Lots of leaky seals on this old hoe. I'm working on fixing the worst offenders first. This is an early model 580c with 2 piece pistons. There's a flat white seal that was included in the seal kit Its relatively soft. I can't seem to figure out where it goes. It seems like the only place it would fit is underneath the wiper seal...but if I put it under the wiper seal, then it seems like the wiper seal will sit too high in the gland. I attached a photo and pointed out the seal. Does anyone know where it goes?
Hello from the New Jersey A lot of seal kits have extra parts for other applications, you probably don’t need them for yours.
Looks like the seal that goes under the gland seal. The gland seal looks to be the one above the one you pointed out. As nova said, there is a chance your cylinder does not need this seal.
That seal is called a buffer ring. If it is to be used, the gland will have a specific groove between the pressure seal & bearing. 580C's generally would not use that seal unless a gland has been replaced with a new one. If your gland doesn't have that groove, the buffer ring is to be discarded.
On my NH cylinders that would be a buffer seal. Note the direction the notch is facing if it has one.
Rebuilt every cylinder on my 76 C machine with 2 piece pistons and had lots of parts left over from kits, OEM and aftermarket. It's a universal thing.
I appreciate the replies!
