It seems to me that the model should be C20B and I think that you are missing a digit in the serial #. It should probably be 291-813 which puts it at a 1966.

THANKS! This truck ***. If you step on the brake on a incline it justs keeps rolling backward and if you are going uphill, such as loading a trailer, halfway up it starts to slip. If you put it in neutral for a few seconds then back in gear it works.

It sounds like a problem with the inching valve or the inching master cylinder. If you take of the floor board and depress the left hand pedal you should see a lever move on the top of transmission. That is the inching valve. Either it is working intermittantly or not returning properly. There is a spring and seal kit available for the inching valve. It sounds like an easy fix (for someone that is familiar with forklift trucks). You might want to call a dealer and have them repair it before you go ripping things apart.

Albany. Thanks for the info. One more question, I don't see a way to check how much to put in. There is no dipstick' etc.

I think Justin was referring to the brake fluid-DOT3. The hydraulic fluid is AW32. The tank has enough hydraulic fluid in it when the mast lifts all the way up and tilts back and forth without cavitating. There is no dipstick because all the tanks are the same capacity and size. It takes alot more fluid to raise the forks 20' than it does to raise them 10'. Make sure the forks are on the ground when you add fluid.

The forks won't raise unless the mast is tilted all the way back or all the way forward. If the mast is straight the forks don't raise, does that mean it's low on fluid?

tilt is a double acting cylinder in almost all forklifts these days, and as such, the same amount of oil is returned to the reservoir tanks as is taken out, only the lift cylinder is single acting, taking oil from the reservoir to fill the lift cylinder.

if the fluid was low, as you raised the mast, it would start to shake and shutter as air is being pumped into the cylinder New York, New York its a heluva town ..you know that The Bronx is up ..and im Brooklyn down

The only reason I thought the fluid might be low was that it leaves puddles whenever it sits for awhile

The lift problem is probably the age of the machine. You have an alternate path through the control/spool valves and or the tilt cylinders. The previous advice about hiring an experienced professional is solid advice. Understand Clark has never been a stable company and of sound engineering practices. By that I mean they utilized very strange technology; whether converting a diesel engine to propane or using wet brakes inside the transmission. Clark has been sold, gone out of business, etc. many ti mes. You will need a very good mechanic for this unit. The average forklift mechanic will have his lunch eaten by an odd Clark design. You need to evaluate the mechanic you choose carefully and understand it may cost a lot to repair. Also you may not be able to get parts. Veni, vidi, vici.- Julius Ceasar
Value an honest mechanic, he earns his pay.

I disagree with Submariner. This truck was built when Clark was king and had about a 40% market share. I am quite confident that you can get any part that you need for this truck although in some instances you may have to settle for a used one.
