[QUOTE="tech.35058, post: 123912, member: 14347"] I have reassembled my machine. I have not "completed the repair" because it appears that I am still transferring oil into the gear case. When I do it again, it should go much better, since I am now "experienced". ( & I have made a cab jack, & all the crowfoot wrenches needed for the job) I failed to heed Shanmar's very good advice to replace the o-rings while I had the pumps out. After all, mine weren't leaking. After all the gyrations, removing hoses, replacing hose, tightening hoses, they were now leaking. And Tedious to fix in the machine. For the un-initiated, JIC caps & plugs in the -16, -14&or-12, -8 and maybe -10 will be useful if you do not totally drain your oil tank. I already had a set of smaller crowfoot wrenches, but this job called for 1&1/2 inch, 1&1/4, i think 1& 1/8, and 7/8. I could have used a 9/16, also, but just didn't. It is not impossible to make your own, but it takes a lot of time. I am of the opinion that torque specs are published for a reason, & have over tightened & under tightened enough stuff to do me. Since I had the spec, and a torque wrench, I took the time to use it. ( My former employer would have been unhappy if I took time to do this on his job, but this is my machine, and any do-over is on me.) I will recheck for oil transfer since I ran the machine several hours yesterday, but I expect this to be a "do-over". when I installed the new rubber cased seals, one would not stay in the seal bore, but kept "popping out". I pressed it in & installed the retaining snap ring, but this is my prime suspect. in the do over, I will attempt to get the proper old style metal cased seal. we shall see. I will try to post photos of the torque charts later, for any one that would like to kknow the "real specification" Remember, if you replace a grade 5 bolt with a grade 8 bolt, the female threads( unless you changed them) are still made for grade 5.
