I have a customer with an older clark c500-100 with leaking lift cyl seals in the upper rams. usualy my company sends these out to be rebuilt by a cylinder shop, but the customer is concerned about long down time. I have a friend who used to work for a clark dealership who said that theses aren't to hard to repair if you have the correct packing tools, and impossible if you don't. Are these packing tools available for purchaes and where can I get them if they are? I can get the mast and cyl #s if needed, I just don't have them right now. thank you. Andy.

Andy,
if you still need the kit I can dig out the info I have. I recently ordered a hub seal installer from the same machine shop that manufactures the tooling for Clark. You are talking about a triple mast- I assume.

Andy, there is a reason your company sends them out. They are an absolute bear. If this is the telescoping type cylinder the gland nuts are brass and have very little tolerance for pressure. If you use the typical chain or spanner type wrenches (or even worse a hammer and punch) you will deform them and then you will have the cylinder back out again going to the hydraulic shop. I am sure you are a very competent tech but this is a fight you will loose 8 out of 10 times unless you do them everyday like a hydraulic shop. Just trying to help a brother out when its hot as hell out.

Andy, compound cylinders are a pain you need to send it out the labor to do the cylinder will kill you if you have a warranty issue.
we are a clark dealer and my guys replace the gland nuts and have the rods rechromed ,if they are going to rebuild. we mostly send them out. It is the best savings for you and your customer.

Thanks for the feed back guys, truth be told, I realy don't want to do it in the field, the customer was trying to avoid the extra expence of transporting the machine back to the shop and all the related down time, and I don't blame them for trying to avoid all that. Since not all the seals are leaking, putting feelers out about a field repair seemed reasonable. Next time I see the guy I will tell him that the international council of forklift repair elders give that idea a thumbs down! ;)

Andy,
At the risk of being appropriatley chastised.... I have resealed a few of these in the field. The top two packings in the truck is what I am talking about. Never this capacity- but I think it is just a matter of scale. The trick is getting the brass collar above one of the seals out as I recall. I can check my teardown pics if you want, but it seems that one gland nut does not have a collar- just the seal. On this one you just pick it out. On the other seal, I chain the free lift from moving, remove the gland nut, start the machine and feather the lift spool just enough to push the collar and seal out. Take the top bracket loose, snap ring-ring- and 3 dogs. Remove and clean gland nuts, sealing area inside tubes as well as possible, grease and slide seals on place. Push one side of seal in and gently work the remaining seal in- pushing with a wooden dowel rod.
