The upper top hydralic cylinder, being 3 3/8 dia x 36: L, is leaking oil and I do not have a repair instructions. The top of cylinder is secured by a top plate with 4 torque head bolts. They are not accessible without raising the mast. Do I have to have to pull the mast to its very top, revealing the bolts and allowing removal of the top cylinder. Please help me by telling me the correct procedure to removie the top cylinder. I have the seal ket from Hercules Hydrauic ( the 3 3/8" seal kit pulled from a mast ket clk-1811164-E) at an excellent price. They were very helpful.
Thanks Bill

Call a Clark dealer , so you do not lose any limbs.
I've done a few of these in the past and send them all out for repair now because they are a pain in the *** to reseal without the proper tools -not to mention how dangerous it is. Definately a job for the shop with some old guy technology on hand! good luck
thank you for the correction, Larry m...
maybe I should only post while I am awake, waddaya think?
Able machine in Taylor, SC
is this one with a telescoping cylinder, that has a couple chrome sections that come out from each other?
I would not tell you to try and repack this type cylinder, since the size of the sections makes it pretty difficult and the alignment is pretty critical to getting it all back together. I would tell you to send that cylinder as a complete unit to Able Machine in Taylor, South Carolina (thanks Larry m) who sort of wound up specializing in this type of cylinder.
Yes- you need to raise the upright until you can acess the bolts. Chain all the rails (you'll need at least a couple 3/8 chains) togeather and make sure they're secure by lowering the rails on the chains with the hydraulics. Take a good look at the chains and make sure they're looped clean- make sure the chain is supporting the rails- not something is caught in between them. It's very dangerous. If the rail comes down on your arm, or even worse your neck it will make for a very bad day! If your not sure- call your local Clark dealer- ask for one of the old-timer mechanics to do this for you. We've done alot of them!
