Carl: Thanks again. Today I pulled out all of the contacts. They are solid Silver and replaceable. They were not that bad, so I reground them to the original slight arc and polished all 8 and that made a huge difference in the for/aft control. Then an adjustment to the lift and tilt switches got rid of the jerky response. I fetched the leaky cylinder from the hydraulics shop and re-installed it. I used the machine all day with no control problems whatsoever and no more leaks. I also received a manual thru eBay today. It covers the Allis Chalmers ACE 20 thru 120 series Electric forklifts and has all of the schematics and systems trouble shooting info. It looks like my system is not Actronic, and after reading the Actronic section of the manual, that's a relief. So, I'm in good shape now thanks to all of the help here. Thanks guys.

If you can find a LPM lift dealer or a Crown dealer they should be able to help with the electrical parts Contact tips could help if they are arcing or depending on the control system {actronic or GE } it could be as simple as an adjustment or control potentiometer in the foot pedal control box think of it as a volume control on a radio If its a GE system there should be a creep adjustment on the control card that adjusts the initial start speed  so it barely moves when you push on the gas pedal There is also a 1A time on the control card that adjusts how long it takes for 1A to pull in at max pedal and should be a smooth transition to max speed If its an actronic system all bets are off as they use different cards to control speeds and are a nightmare to work on LOLHope this helps and PM back if you have questionsCarl

Thanks. Found a completely dry Master Cylinder and filled it. It took quite a bit of time to work all of the air out, but the brakes have been holding solid for the last few days. I found several tilt cylinder kits, all different numbers, but without a parts manual I thought I'd be throwing money away. I did find a local machine shop that agreed to rebuild the tilt cylinder for $100. They have it now. My next project will be trying to smooth out the slightly jumpy controls. From what I've read, the controller contacts may need service.
