Ford 3600 pinion carrier

Hello forum members, long time viewer first time poster here. I was changing my trans and hydraulic fluid in my tractor, and while I was at it I took the inspection plate off of the left side of the rear end housing. The PTO had jumped out of gear on me two times this year while bush hogging. I wanted to get a look at the dog clutch on the PTO shaft. The splines on both halves looked like new so I m hoping it s just the detent, anyway to the point. While I was in there I noticed there were six mounting bolt holes in the pinion carrier, and two pulling holes, however the top and bottom mounting bolts were missing. There is not a mark one on the carrier, so I believe they were never there even though there feels to be threaded holes there. Is this normal?

Yes, I've seen that before. If the other 4 haven't come loose by now, they never will. A 3600 doesn't
generate enough torque to even remotely stress those bolts.

Thanks for the reply Bern. I was hoping those others weren t rattling around loose in there. Since posting I noticed other pics on internet with those same bolts missing, any idea why Ford would make provisions for those bolts and not use them?

This is pure speculation on my part, but I would assume it's the way for engineers to be able to easily step
up power levels within an existing housing, thinking ahead to future needs. Either that, or they designed it
with 6 from the start, and then some other engineer/bean counter decided that it only needed 4 and that they
could save money and time by leaving 2 out.

Your probably right Bern. I guess some of this stuff will always be a mystery and up for speculation, anyway thanks for the replies.
