Nope... dissembled Johnny-5, I don't know why I did that

I would go with the volt meter. Easiest and it tells most of the story.
Either that or the new hour meter.

Has been a diverse and wet/stormy weekend for me. I finished up some small paint jobs and cleaned up the electrical items. I replaced the connector terminals on the stator, and cleaned up the regulator. Ended up in a discussion on an electronic forum as to how the three terminal regulator worked internally (incase I needed to build a replacement) I did find a OEM regulator online just in case. I rebuilt my test power supply, and put new seals in the timing gear cover. Rear bearing gasket should be here tomorrow.

Finally some engine progress, front bearing cover installed and pistons installed. Even though I bought a ring compressor I still had to use a band clamp to get the oil ring started.

Any suggestions on installing the timing gear? I can't seem to get it on far enough to line up the key. The key is still in the shaft, never came out. I tried tapping it on with a rubber mallet and PVC. No luck, and this thing has sharp edges. I am thinking of putting the gear on the grill and heating it up and use gloves to see if I can at least get it lined up with the key and drive it home.
Thoughts?

In the B48G Service Manual, it says to heat the gear and drive it on. Getting it aligned while warm may be fun, might use a pair of channel locks to set it in place. Gloves may get warm!

You're going to want to use something other than PVC. Maybe have a big, deep well socket ready.
If you have a deep freezer, I would freeze the shaft and heat the gear. Every micron is a help.

I'm sure the wife will let me put the block in the freezer, I'll tell her you recommended it.

Owwww, had a thought. What if I heat the gear on the grill, and pick up some dry ice and pack it around the shaft. Hmmm. sounds like a plan. I'll need to bring my cooler with me tomorrow.

[larrybl]

I will try heating the gear on the grill a 375 - 400 for a half hour or so tonight and see what that does. Some are saying it should slide on easily after heating.

I'm sure that would carry as much weight there as here...

Took the afternoon off to mow grass as we are expecting rain/storms/sever weather through Sunday, and the grass was thick. Clogged up the deck on RED twice. Any how, I fired up the bbq and brought it up to ~600 or so and roasted the gear for 25 minuets. The last 5 minuets I wanted to see how high the grill would go... 750    I put on leather gloves and used a large channel lock wrench. The gear slid all the way down on the shaft slick as snot. No force needed.   Lined up the cam gear and installed the thrust washer and snap ring. Thanks for the heat suggestions, worked great!

Glad it worked!

Coming along nicely Larry glad you got the gear on. My first experience of heating a gear was on a 1966 Volkswagen, I was about 22 years old. It went on so easy I thought I screwed up. Did you marinade the gear before roasting :)

I posted this question over at Onanparts.com.

"I was looking over my notes and I have a question on the oil rings. I had some difficulty compressing them to get the piston installed. Thinking back, the old rings had a "octgon shaped" spring that installed behind the rings, the new oil rings did not come with this spring, but the manual indicated that it needed to be there. Did I make a mistake leaving the "spring" and installed the new rings and spacer over it? At this point it can be removed if recommended."

 

I actually had this question in my notes, read the manual, and installed the pistons. This kept nagging me so I decided to ask before I got too far with the assembly.
