All the parts are back except for the ones I forgot to order which I don't know about yet cause we haven't got that far yet. I'm sure I have enough to build 95% of the engine anyway. It's all new except for the heads, oil pump, and crank which was repolished.

Gotta take a first step. Ring gaps. Here's the top ring at a depth of 12 mm (top of piston to 2nd ring). .019". These are pregapped from JE. Everyone say run em at that gap. All rings were between .018" and .020"

Time to move on to another task. Put the can gear on the cam. The gear is countersunk and the bolts are shortened to make room for the Schadek oil pump. The old gear is on the right with no clearancing.

Dave,

Are those your replated Nikkies, or new ones?

I remember these days... (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/cool.gif)

Have fun!

The gear will only align one way cause the spacing of the holes is not consistent. This is not right

After chasing the bolt holes and cleaning I tightened to 18 lbs with Locktite 262. Job done.

On to the crankshaft. Time to install #3 main bearing, timing gear, spacer, dizzy gear, and retaining ring. #3 bearing is on with hole for dowel toward the flywheel end. The wife is gone and the gears are in the oven heating up. Fortunately, I have about 6 hours to get the smell out.

Lookin good Dave!

Glad you are back on it- sorry it took a while- we were trying to dis-sect the issue piece by piece.

Here's the rest of that assembly. After the bearing, the gear to drive the cam goes on. The only hard part is the side with the chamfer fits against the bearing. Next is a spacer, easy to forget. Then the distributor drive gear and finally a retaining ring go on. Access to oven cost some shopping time. Money well spent, she'll never know the difference. Coarse, I cleaned everthing really well first. 400 degrees for 30 minutes got the gears hot enough to expand them so I only needed a tiny bit of persuasion on the cam gear. It was really pretty easy except for the run from the kitchen to the shop.

On to connecting rods.

Dave

Dave, a small cooking eye works well for the gears... sit them on the red hot eye and cover them with a valve cover for 20 minutes and they'll drop on like nuttin!

Ha Ha Dave. When I did mine I didn't bother to make the run from the oven to the garage with the hot gears. I brought my crank inside and set it up on the kitchen counter right next to the oven. I did get some strange looks from the wife on what I was 'cooking'. But she didn't complain. No smell, no mess, so I wasn't worried.

Actually, it wasn't any problem. Everything went fine. I am glat the wife wasn't here though. Just 1 less "nutty" thing to explain.

Laid out the rods and bearings.

I was wondering what the outcome to your motor was...
Glad it's moving forward and hope it's a success this time.

I checked the clearance with Plastigauge All 4 were .001". You'll have to trust me on this but the area between the orange lines is the plastigauge.
