    Hydraulic Lift Valve

    Solved! I partially disassembled the pump by removing the end covers, piston yokes and cams. Four bolts did it plus the sleeve retaining screw on the front, item 16 in the exploded view. With the housing open, you can see the square shaft sticking out the front through a fork sleeve, item 14...

    Hydraulic Lift Valve

    I think my pump may be scrap. When I removed it, there was no spool shaft sticking out the front and the spool and possibly the spring is deep inside the bore. I tried fishing out the spring (if it is still there) with no luck. Also the square end of the front rod sticks out of the housing...

    Hydraulic Lift Valve

    While removing the lift cove on my Ferguson TO30, I spread the fork arms to release the valve stem bar and it fell to the bottom. Somehow it had become disconnected. Just before that, I made the mistake of trying to lift the cover without disconnecting it and possibly that forced the clip to...

    Old Lift Cylinder Rod Packing

    That's beginning to sound like a good idea. After watching the Pakastanis straighten cylinder rods I might consider trying it as a DIY project. I don't have a big press or heavy steel beam but we'll see. I sent out four RFQ's for the packing sets. If any are not too expensive, I may give it...

    Old Lift Cylinder Rod Packing

    Thanks, I'll send an rfq. One of the rods is bent about 1" in the middle. Is it worth straightening and fitting new seals? I can get a new cylinder for $220 with free shipping.

    Old Lift Cylinder Rod Packing

    Thanks. This is very informative. I'll give them a call. For 2500 psi table 2 recommends a 4 -5 vee stack which is higher than my 1" gland so I'll need to talk to a rep to figure it out.

    Old Lift Cylinder Rod Packing

    Did that already. They're the one that took the caps off for me. Their estimate was $1200 for the four. I will try Baum again. I did get a quote from Hercules for about $200 with shipping for the rod packings so a little progress is being made.

    Old Lift Cylinder Rod Packing

    The stack you referenced is 1.25 thick but the gland is only 1" deep. The price with shipping for the four cylinders is around $300 just for the rod packings. This after I paid for sandblasting the old paint off, another $160 to a hydraulic shop to loosen the caps and gland nuts and before...

    Old Lift Cylinder Rod Packing

    Thanks, this confirms what I've heard from other sources. So far, standard stacks including the end pieces fall 1/16 short of my measured packing. Perhaps a shim washer might be used. I'm still looking for the right kit. There are a lot of materials to choose from. My system operates under...

    Old Lift Cylinder Rod Packing

    Here's an overview of the disassembled lift and tilt cylinders. Except for length, they're all the same.

    Old Lift Cylinder Rod Packing

    Here's the cylinder end cap and screw in gland nut. The end cap screws into the cylinder and is sealed with an o ring. The packing in the end cap is 2-1/8 OD x 1-3/8 ID X 1 which you can see inside the end cap. The assembly procedure is to screw the end cap into the cylinder, tighten the nut...

    They said they don't have packing seals.

    Tried Baum; no luck.

    Not Baum, though I'll give them a try. I did check with a hydraulics parts distributor in Oregon with no luck. No dice at Mc Master. No hits on Safari/Google.

    Old Lift Cylinder Rod Packing

    My tractor has an old Lord front end loader from the '60's. The lift and tilt cylinders are 2-1/4 bore and have screw in rod gland caps compressing cylindrical rubber packings 2-1/8 OD x 1-3/8 ID x 1 long. I suspect they're 90 durometer Buna-n. I can't seem to find packings of the correct...
