For the ignorant among us (certainly me), other than the kit, how best to go about getting what you need? Seems to me that there either must be a general parts reference somewhere to identify rings/seals by part number or dimension. Or you pull it down and take it to your local purveyor of such parts (if there is one) and let them figure out what you need, and hope they both get it right AND have it in stock for a decent price. At least that's been my past experience on such things. Is there a reference to help?
I ask because the I've got the two main (inverted) cylinders on my B2150 (loader numbers are long faded and gone) that weep themselves dry even with the pressure relieved. They work just fine and don't leak noticeably in use, but long overdue for a rebuild, and I hope to get that done soon. Bucket tilt seems ok, but I'll probably do them at the same time.
