These videos contain trouble shooting tips for Ragtime Roll operated machines. There is a buy now button below each video. Please be sure that this is the part you need by following closely all instructions.

Before you can trouble shoot a Ragtime O roll machine you must remove the front panel as shown:

It would be a good idea to check the rewind switch adjustment before proceeding. This will eliminate or demonstrate the need to adjust it. Please follow the video below:

Adjusting the spool frame brakes. The paper should not never be loose...It should have a slight amount of tension to keep it against the tracker bar. Too much tension will result in cross tracking and could tear the roll. Never tight, just enough tension to know it has tension.

If you are having rewind or play problems you will need to trouble shoot the Roll Frame as shown in this YouTube video:

If your Ragtime Machine goes into rewind when you turn it on you may need to replace the Lock and Cancel valve:

This is a diagram of how the tubes from the Lock and cancel valve hook up to the Suction Motor and the Trackerbar.
Follow this YouTube video to replace your lock and cancel valve:
This is the Lock and Cancel Valve shown below:
If you have determined that you will need a Lock and Cancel Valve you may order it here below:
If you just have a broken Bleed Cup, shown below, you may order it with the Paypal Button Below.

The paper roll runs as shown here. Off the back of the top roll and over the back of the bottom take up spool. The edges of the paper are approximately between the two sets of staggered holes.
Please notice that there are two sets of staggered holes. One set on the left and one set on the right of the tracker bar. Photo below. The paper will touch one or sometimes two of these holes on each side. They vary because of varying paper width. Paper swells with humidity. If it was cut on a rainy day it could shrink on a dry day so the width of the paper will vary about 1/16 of and inch from time to time. It is your job to then adjust the holes in the paper to run directly over the holes in the bar, provided it is centered between the staggered pairs, more or less.
Staggered holes on the right side of the tracker bar.

This is an A162 Calliope Pipe Valve. Used in all our roll operated calliopes including the D42r. Order below if you need one.
If you find broken elbows at the pneumatic, you will need these:
One elbow or in sets

If you need the elbows you probably need some 5-32 inch Ts.

Ts for tracker bar tubing
This is a Drive Dog:
This Green super glue is thick enough to build up and the pink is thin enough to seep into thin cracks. The debonder takes it off your fingers when accidentally encountered. The Zip Kicker causes instant hardening when sprayed on sparingly. Be careful, it gets hot when they come into contact with each other. 1 ounce of each plus more of the zip kicker

This is a Drive Dog:
If you need a Drive dog, this is what it looks like and you may order one here:

This is our Rewind Pneumatic:
If you have determined that you need a rewind pneumatic you may order it here:
If your Ragtime Machine is more than 20 years old you may need to upgrade with a new take up spool. The new one tracks better, helps eliminate tearing rolls. It also has a hook on both sides making it twice as easy to change the roll:

Other parts that may be needed are the following:
Rewind Lever:
This is a new and improved rewind lever. Units 20 years old or older have a lever that will loosen. The old one does not have a shoulder or hub like the one shown in the photo.
Right Hand Carrier:
This is a new and improved roll carrier for the right side. Units 30 years old or older have one that may come apart when snapped open. Two sets are used on each roll frame, top and bottom right.
Right Hand Carrier Spinner:
Rarely lost, but possible to be lost if someone lets it get stuck in the right side hole of the paper roll spool end then does not notice it drop to the floor. First look for it in the bottom of the piano or under the piano. To replace it it simply presses in with a slight click.
Spool Frame Motor with sprockets:
Spool Frame wiring harness. If your spool frame speed control is erratic or does not adjust the speed, or only goes in rewind you will need to replace the entire wiring harness.

If you are capable of soldering and wish to repair the wirting harness it is usually the LM317T variable voltage regulator that gets fried due to being shorted out by rough handling. This instrucional will help you do that. To order the parts here just add to cart.
With or without extras

On Ragtime Machines older than 30 years, you may need to replace the complete spool frame. The old ones don't have speed regulation, injection molded takeup spool, leather lined adjustable breaks and many other features. The metal frames were subject to bending when the pianos are moved incorrectly. They were attached to the bottom of the piano which will flex when dropped roughly while on a piano dolly or in a shipping crate. This flexing bends the metal spoolframe which would not return to it's original shape. The new polymer spool frames have a memory and return to the correct shape after being flexed because they are flexible. They are made from a material which has rubber added to it. This eliminated a lot of problems for us since we ship our pianos all over the world and have no control over how they are moved once they leave the factory.

This is the way the transmission should look from the back. Check the sprocket hubs for cracks. You may successfully use a small hoseclamp to repair a crack, as shown. You may also order OEM sprockets from us. If the chain jumps off the sprockets, check for a bent link in the chain. The little "ears" should not bend inward. Check for any cracked or broken parts and replace or repair as necessary.

If you are having problems with the paper tracking properly you may have a tracker bar which has lost it's "bow". This can happen if the rubber tubes shrink and pull on the bar. Raising the spoolframe or relieving the tension by supporting the tubes so they don't pull on the bar will often help. It must bow out in the center about .010" or the paper will not run true. With a .010" feeler gauge at each end of the tracker bar, place a staight edge across. If the center of the TB does not just touch the straight edge, you may need to replace it. Sometimes the little tubes on the back of the trackerbar break, or the tracker bar gets bent. You will need a new one. $180 each. Choose the button below.
If you have a roll operated Steel Drum it may have a special Tracker Bar. Please measure the height of the holes first. All other units use the normal tracker bar.

The sprockets may need to be replaced.
A155c - The upper clutch and shaft wears out after about 150,000 plays. You may need to replace it if it won't rewind manually or automatically. When it wears out the clutch and shaft are damaged and the entire unit must be replaced. Test this by raising the rewind pneumatic. If the unit goes into rewind, you hear the motor speed up and the roll doesn't reverse it may be bad. Please check that the hex drive knob is not stripped out inside. Sometimes this happens.
A178 - This is the Lower Clutch and Transmission. If the bottom takeup spool is forced or held in place, the transmission can be broken. You may need to replace it if it binds on rewind.

If your roll lurches forward and stops when you go from rewind to play you have one of three possible problems:
1. Slipping or cracked hex drive to the bottom spool. To check this, rewind the roll to the top spool. Remove the bottom spool. With a flashlight look to see if the hex knob is turning on the left bottom drive shaft with the unit in play. If it is turning, grasp it with your finger and thumb and see if it stops easily. It may be cracked. If it is, you will need to replace it. You may buy one above.
2. The drive sprocket on the motor shaft is cracked. If this is the case, the top chain will be moving, but the lower chain and hex drive won't be. If you determine that the hub to the drive sprocket is cracked then simply put a small hose clamp around it and tighten. If none of the chains are moving, and the hex knob just jumps forward a little then check for problem 3 below.
2. The lower clutch is worn out or damaged. If the hex knob turns for a moment and stops, look to see if the chains are moving at all. If they only move slightly then all stop, it sounds like your lower clutch needs to be replaced. This is especially the case if it binds up half way through the roll rewinding.
Our pneumatics can be tested with 3 pieces of tracker bar (1/8") rubber tubing. Take a 15 foot piece and attach to the nipple. Attach vacuum to the supply nipple and then tape over the other side. With vacuum on, place and remove your finger over the end of the tubing. The pneumatic should work ok, maybe a little slow but it works. If it doesn't work, or is very slow, try it with a 10 foot piece and finally a 5 foot piece. If it doesn't work with a 5 foot piece of tubing, it is bad. 15 feet is the desirable amount. All pneumatics here can be tested in this manner except the no bleed pneumatics used in the Glockenspiel and the cymbal. They must be paired with a normal bleed pneuatic using a small T. Then test as the others are tested. Both pneumatics should work at the same time. Below are the various pneumatics you will need. All the no bleed pneumatics are piano pneumatics without a bleed. We also use piano pneumatics for some instruments. The only difference is the amount they open. The large skins open a little further for a longer stroke.

This is our Piano Pneumatic.

This is our No Bleed Glockenspiel and O roll Cymbal Pneumatic.

This is our Reiterating Pneumatic with valve. Used on the Snare drum and optional on the woodblock and tambourine.
Reiterating Pneumatic
This is our Large Skin Pneumatic, used for rewind and some instruments.

This is guitar, bass, banjo, ukulele, bailalaika, mandolin Fretter pneumatic.

This is guitar, bass, banjo, ukulele, bailalaika, mandolin Plucker pneumatic.

This is a piano stack of pneumatics. Our current pianos come with 54 notes and a special tubing arrangement which sounds better than the previous 66 note stacks, costs less and stays in tune longer. If you have an older nickelodeon or Ragtime nickelodeon made before 1986 you will most likely need to upgrade to the new design and tubing arrangement. The older designs show signs of failing after 20 years, however the new design, since 1986, has not yet shown signs of failing. If you do not know the age of your conversion, there are some signs. Tan pneumatics, pneumatics with ridges across the back, purple skins, aluminum bodies or pianos with soldered together brass T's.are all between 1971 and 1986. Order either upgrade here.
Replace Stacks

A161 - If you are on a budget and wish to recover the old pneumatics yourself instead of buying new ones you may want a yard of two of cloth

12 note double Bass Kit

This is our Double Bass kit. It consists of 12 pneumatics made without bleeds so that you may Y tube them directly to the octave above. This makes the nickelodeon have a much richer bass. It is also available with bleeds for other projects. Please select the correct one below:
Double Bass set options available

If you would like to convert any existing antique upright piano into a nickelodeon or digital piano then perhaps one of our conversion kits would be right for you.
Piano Conversion Kits

Our first style of stack, made from 1971 until 1977. Individual pneumatics tubed to a stack of valves. The predecessor of the unit valve pneumatic. Hand made. No individual photo available.
Various versions of our pneumatics over the past 40 years.

If you are on a budget you may purchase the Ragtime pneumatic rebuild kit. The prices for the various kits are listed below. Click on this YouTube link for a tutorial on how to assemble the pneumatic once you have dissassembled it.

Pneumatic Rebuild Kit - Consisting of one Precut Pneumatic Skin, Pouch and Pouch retainer. In most instances this should be enough to rebuild the pneuatic. There is a 90 degree nipple that may break, available above and the valve may be hard. It can be taken out through the top valve hole with a small pair of needle nose pliers then the new one may be pushed back in with an 1/8" dowell.

Pneumatic Rebuild Kit

If you would like to try covering and trimming the cloth yourself, you may purchase the pouch and retainer separately here:

Click on the following YouTube video for information on how to rebuild the pneumatic. There are Spanish Subtitles too.

MIDI valve for Ragtime pneumatics.

$5 each. This is a pneumatic spring, most are black. It is especially made of virgin acetel. It last longer than steel without breaking for more repetitions. There is also a lighter version which is brown, but not common. If you need brown they are the same price. Although the plastic springs never break, they do fatigue easier than steel. Steel is better for high performance and for weight which will be pushing down on the spring with gravity indefinitely.
Two strengths

$12 each. Steel Spring replacement for all plastic Springs.

This is a pair of Spool Ends for piano rolls not made by Ragtime so that they can fit a Ragtime O roll piano. The left side as a hex drive, the right side is round for a spring loaded pin.

This is a normal Ragtime Vacuum motor. If you have and older unit and need a replacement, it will probably be taller and painted black. For the last 20 years they have been white with black top and black bottom. They have mostly been round. Some ultra quite boxes were built for pianos with the room. They are square with this round motor inside for sound insulation. Ultra quiet motor not shown. This is the replacement for the one inside. If you want to upgrade, order the Ultra Quiet. Be sure you have plenty of room for it. There is a third option and that is the commercial model. It is a brushless motor with a liftime of 30 years. It is very expensive, but necessary for 24 hour continous use.
This is a photo of a Ragtime Pressure motor. Note the pressure elbow on the side for 3/4 inch pipe. These are used in pianos with pipes, calliopes or some pianos with accordion if it is on pressure. Accordions may run on pressure or vacuum depending on what instruments accompany it. If with pipes, the accordion will run on vacuum to balance the system.
Ragtime Replacement motors
Sometimes a customer may wish to locate the suction motor in a remote location, say for recording. This keeps the unit quiet of motor noise. Doing this will require a cut out valve to be located in the piano near the roll frame. It should be within 3 feet. A cut out valve will also be necessary if you want to shut off an instrument automatically using coding in the roll. Please be sure to select the correct one below.
Vacuum Cut Out

This is a set of 6 of out pluckers. They slide over the control arm. Snap in place. If your clutches (ratchets) are fine, you may replace the pluckers. Availble one at a time or as a set of 6.
Pluckers Only

If your pluckers are not broken but the ratchets don't grab quickly, they may be worn out. It is recommended that you replace them all at the same time.
Complete Plucker Assembly

Click on the YouTube video below to see correct Coin-Op adjustment procedures.

This is our Pneumatic Coin Op. It is quite simple. A quarter dropped into the slot holds a 10amp Cherry micro switch closed and the piano comes on. At the end of a song an air signal from the roll passing over the tracker bar causes the pneumatic to kick the quarter out and the piano goes off. Adjustment is critical. 1/8" from the resting Corner for the coin trip wire. The push rod must be resting firmly agaist the back.
You may try replacing the micro switch if broken, try replacing the pneumatic if not functioning. If you would like a new one you may order it here:

Often mishandled and broken, you may need to replace the switch. It is a modified Cherry E51 and requires special tools to attach the wire. You will need to follow the adjustment procedures to replace it setting the "let off" to about 1/8 inch shown in the video above. You may order one below.

We have these double rubber wheeled piano casters made expecially for us. They protect floors from marring and they roll nicely on carpet. If you have a broken caster you will need to replace them all as they are different heights and the others will break anyway. 16 Extra long screws (not shown) are included just in case you need them. Often the screw holes are stripped, so you may need them. Also, we make caster spacers. It is possible you may need to raise the caster away from the piano a bit so that the double wheels can miss the piano bottom or recess edge when it rotates. 4 spacers are included as well, shown in the photo. Also there are 4 caster sockets included. Many old upright piano casters have 3 screw holes, ours have 4. If this is the case you will need to drill a pilot hole for the screws.
