I continue to work on my Allis Chalmers 1942 tractor. I am going to replace the seals and gasket on the PTO and the Belt Pulley. I have found a few older messages about doing this, but I thought I would check and see if there is anything new I need to know. I have a 1-1/8" shaft, and it probably has the "oil return groove" others have mentioned. Others have mentioned a need for a speedi-sleeve but not where to get one. Fortunately, I am only a few miles from an ACGO dealer and a NAPA store. Any tricks in getting the old seals out? I hate doing all this and discovering I missed something or the shafts are still leaking, so thanks for any heads up advice ahead of time. P.S. I do have the tractor running now.
