Have the rod out of one cylinder so just the tube is mounted to the tractor. Noticed during disassembly there is a good bit of play where the cylinder mounts to the round crossmember/yoke (whatever it is called) that passes behind the radiator. How difficult a job is it to renew whatever is in there? Cannot see how the thing comes apart so help is needed there too. '67 D4/D4D 78A7171
There are a couple of retention methods. Look for two or four bolts that retain a lock pin on the cross shaft. Two bolt version has a grease zerk in the end. Fits in a groove on the yoke stub shaft. There are two bushings/bearings each side that supports the yoke.
The bearing/bushing there is a zerk, inboard of it are two bolts. Is there a shaft that extends from one side to the other or can the right and left assy's be individually serviced? How big (heavy) a job is replacing the bearing/ bushing, all I have is armstrong power for lifting.
The yoke shafts are separate, just long enough for shoulder to retain at the bolts. Yokes themselves are not that heavy but along with the cylinders that's to much to be lifting without assistance.
The cylinders are just hollow tubes at the present while the piston/rods are having the yoke end turned to reduce slop and packings replaced. Might be with the bare tubes the weight is manageable. You mention two methods of retention, any chance they both use the same bearing/bushing part numbers (hint, hint)? Thanks OM.
Both the 2-bolt and 4-bolt retention arrangement use the same bearing/bushings. Inner small 4J4233 (2-reqd) Outer large 4J4232 (2-reqd)
I am bunping this up to ask another lift cylinder question; Which way is the piston supposed to be installed? After replacing the seals in one cylinder (where the sealing ring was closest to the nut), the other was disassembled to find the piston was on the rod the opposite of the first. It appears it works either way but which way is correct?
The deep groove for the seal should be farthest away from the nut.
Good, I won't need to go back into the first cylinder. The one I tore down yesterday is backwards. BTW, thanks for the part number help, changed out the yoke bushings over the weekend.
