Was gunna ask. But I figured I should not.

They know you need a break from too many projects

[Eugen]

Yeah Matt, I'm lucky they're looking out for me

@propane1 no harm asking, ever.

I've decided to start working on the backhoe again. This evening I've replaced the main bearings. Took me 3 hours, not a walk in the park but not horrible either. Not sure what's worse, working in the freezing cold snow or in sweltering heat and mosquitoes attacks. The bolts for the bearingcaps take a 15/16 socket. Have not torqued them to spec yet, don't know the spec yet either. My torque wrench maxes out at 150 ft-lbs, might be too weak.

Found the value in the service manual: 145 - 155 ft-lbs.

@Eugen I have one you can borrow . it maxes out at 250 lbs. Will be more acurate for that job.

Thanks Dave, I'll take you up on this. Next time I come by I'll bring the sleeves for a rub too.

Glad you’re making progress @Eugen.
I know this one has been kind of aggravating. I’m hoping it’s a short road from here to having it running again.

Thanks, it is what it is. Sometimes in life things don't get resolved according to our expectations or desire. The company that I ordered the sleeve and piston assemblies on March 3rd has delayed the shipping date every month, and now I have given up on that. The sleeve and piston assembly is a kit that would include sleeve, piston, rings, and sleeve o-rings. I've been told that it's the sleeves which are continually on back order, while the other components are available to buy separately, not in a kit. Guess what, it's about 400 USD more expensive to buy these parts separately. It's not that great.

But here's another piece to the ramble. The other day I replaced the main bearings, meaning, the old ones were in the tractor, the new ones in the box next to me. The upper bearings are a little tricky to get out, involving turning the crankshaft by hand while inserting a thin rod through the lubricating hole in the shaft journal so as to hook the upper bearing and slide it out. The bearings that were at the far ends of the shaft were the hardest due to the position and hard access. So out came the old bearings, and I wipe them and inspect them. I read STD on them and it dawns on me that the new bearings sitting in the box are also STD. Same with the the rod bearings, by the way. Thank God for sparing me the extra pain of having to order a different size of bearings, because I was so short sighted that I did not check which size bearings were in the tractor and simply assumed they were STD. Phew!!!!

Luck was on your side that time Eugen.
