A box of parts arrived at my house on Monday and I finally got started with reassembly today. Realized I forgot to order a rear cover gasket and PTO valve gasket so got those ordered right away. The differential, pinion shaft and diff lock fork all have to go in together, took a little bit but it went together. Then got the PTO brake piston inserted and lined up with the brake shoe. Installed the pinion drive and range selector shafts and torqued on the front case. Once that was done I could install the PTO brake springs and tighten that up, along with the range selector detent ball and spring. Everything seemed to work as it should so installed the hydraulic pump and hydro drive motor. Then cleaned up and bolted on the axle housings. Pretty much stalled until I get the gaskets.
This afternoon I was cleaning up and discovered one of the alignment pins had stuck in the old cover. With numerous studs along with the other pin I just didn't notice. Was able to pull the axle housing, loosen the cover and get the pin installed with minimal effort. Only problem is now that the whole front case assembled, I can no longer see that the PTO brake piston correctly engaged in the shoe. Pretty sure it's fine but another thing to worry about. Probably take an hour and a half to pull the pump, hydro motor and front case all apart and put it back together again just for a quick look, but that's the only way to see. I'll sleep on it, maybe remove the PTO brake piston again, measure the depth, just take another look at it.
Took a bunch of pics during assembly, then run a borescope up behind the gear to see how well I could see the bolts. You could easily see the bolt heads but you'd need to rotate the differential to see all of them.
I bench tested the high strength loctite on a 1/2 bolt and it's very stout stuff. I cleaned the bolt with brakleen, then applied primer, loctite and threaded the nut about halfway on by hand. Next day I put a 3/4 " wrench on and leaned into it, the bolt turned just slightly then locked up. I pulled about as hard as I could and it would not budge further.
