Re: Engine Work - Update
Good work! Glad to hear that you are making progress. Keep pecking away at it, lots of winter, working in the shop weather coming to the midwest this week. That is if your shop is heated..

Re: Engine Work - Update
Hopefully your ring end gaps fall in the correct range and you won't have to adjust them by filing.

Re: Engine Work - Update
Looks like ring (Hastings) end gaps are within spec. Clearances were .010 for the top rings, .009" for all four bottom rings, and .035" for all the spacers (above/below oil retainer spring). All ring end gaps were consistent at same location in each bore. I took a top ring and placed it into the bore, squared it with the piston, then measured the end gap.
Hastings manufacturer info sheet spoke of a dot, laser mark, or no mark on the rings. If dot or laser, then that went up; if no mark, then it didn't matter which way was up. Mine didn't have any discernable marks on them.

Looking good. It's always nice when you don't have to file the rings to size.

Re: Engine Work - Update
Had a big ol' time in the shop this afternoon. Wanted to take advantage of feeling good and having the time and warm weather. Supposed to get 6"-12" of the white stuff tomorrow.
Since all my bores/rings were within spec, I got the pistons loaded up with rings and upper bearing.
Once piston was in, installed the connecting rod with new bearing, hand tightening the nuts. Engine assembly lube was used.
Once everything was in place, I torqued the connecting rod nuts to 20 lbs/in per the Specs. Here's the finished install of the pistons:
Next, was getting the exhaust/intake valves installed. The machine shop did the initial work of grinding the seats and valves, but I still needed to lap them to fit. Did each one, got the valves installed, springs, caps and retainers in place.
I cranked it over several times by hand to do the valve clearances---IT CRANKS SO NICE AND SMOOTH. I'm looking forward to getting this engine up and running one day. Thanks to all who have advised and comments. You're a confidence booster to an amateur like me.

Re: Engine Work - Update
Everything looks great! I love doing the assembly of an engine. It's therapy for me. I enjoy fitting everything together and making sure everything is just right.

I have a feeling someone is being modest about their abilities here!!

Re: Engine Work - Update
Had some time and energy after church, lunch, and a nap to get the head installed.
Head bolts, thread sealant, and copper coat spray on hand to get this step done.
First, sealed the head bolt receiving threads in the crankcase using a pipe cleaner. I wanted to be sure sealant was there all the way to the bottom of the hole at the water jacket.
Next was sealing the bolts.
I sprayed 2-3 coats of copper sealant on each side of the head gasket.
Lastly, installed head with new bolts torqued to 50 lbs. Taped off the water outlet and temporarily placed old spark plugs in to cover all the holes; don’t want debris getting into the rebuilt engine.

Re: Engine Work - Update
Stanton, I sure wish I lived close enough to you to have watched & learned from this project. Engine rebuild is about the only major task I haven't tackled, and I find it daunting, but from watching your work, feel it would be extremely rewarding.

Re: Engine Work - Update
The engine is looking good, Stanton! I hope you're enjoying the assembly process as much as I do. I've enjoyed watching your progress just like Dale said. You always do such good work.

You're too kind. I'm just trying to learn from others on here by heeding their advice and going along in the "Service Manual: Engine GSS-1007" on reassembling order. Certainly, if you were here, we could bounce thoughts off each other and I'd probably have this thing done by now. I'm very slow; tentative, but I'm glad to contribute (in a small way) to the overall knowledge base here on the Forum.

Again, kind words that I don't feel I'm qualified to receive. But they're appreciated nonetheless. Thanks, Ricky!
