Clark C500 SERIES:
C500Y30 tilt cylinders will not go all the way forward

I bought a used Clark C500Y30 off of eBay from a dealer. They claimed it was totally refurbished. When I received the truck, the tilt cylinders were drifting forward quite fast. I called them and they shipped me out two repacked used cylinders. They are exactly the same length/diameter as the originals.

I got to work and pulled one of the old cylinders off. The pistons on the repacked set were not extended out as far as the originals. Changing the first, I used a ratchet strap to adjust the distance. Pulling the mast in towards the truck, I was able to get the piston bracket on the repacked cylinder positioned and attached to the mast. Then I tightened all my hose connections. I proceeded to do the same to the other side.

When I fired up the truck, the forks would not tilt all the way forward. Eyeballing it, there is easily 6 inches of unexposed piston in the cylinder. I tried cracking the hoses and bleeding air out of the lines, but only fluid came out. I also topped off the hydraulic fluid.

It seems like there should be an easy solution. This is the first set of hydraulics I have tinkered with and I probably missed some step. Any advise would be appreciated.

Thanks

Stam is probably correct. You will have to take the cylinders apart and see if there are stops on the rams. If these cylinders came off of a truck with a three stage or very tall standard mast there will be tilt restriction spacers on the rams.

Someone may have sleeved your new rams to limit fwd. tilt.
This is usually done after a salesman has sold an undersized truck or an attachment was fitted.
To know for sure a dismantle is required.
