'72 Interstate Restoration

06-2600 is what is stock but could have been replace with 06-3020 but I doubt it. Most likely stock 72 bushings.
No flange.

I may have encountered another problem!! My dad and I got the barrels on a few days ago, but from what the manual says, the timing cover chain and oil pump etc. should be assembled first. This is because you need to be able to hold the crankshaft so it doesn't turn while putting the nut on the timing side end. Without thinking we put the barrels on first, is there a way we can hold the shaft while tightening the nut down so we don't need to take everything apart again??

You could just lock up the pistons. Drop a block of wood into the bore and clamp another piece across the top of the barrel.
 
Well, i think i need to pull the barrels again anyways to deal with the stuck cam issue. :x should make it easier to hold the crankshaft.

About the camshaft play, from what i remember i do have the stock '72 bushing and have no idea if the washers ever made it back on. Since the barrels are coming off again ill take a closer look.

Also, I read that camshaft play is not too big of a deal since the timing chain keeps everything in line...that seems right to me. Is it true?

I havent gotten into the barrels yet, but rather rebuilding the gearbox again because there were some things i dint like about it the first time. When tightening the countershaft sprocket nut there is a lock washer that is supposed to go around it with a screw that goes into the sprocket. I cant get the washer to line up with the hole on the sprocket. Ive tried numerous times. Is the washer something you guys wouldnt dare to go without?

Torque just a little less or a just little more to line up. They can be a pistol to get just right but do it.

I also couldn't get the nut torqued to 80ft/lbs before the cases started to turn in the vise.

Also forgot to ask what the best way to hold the sprocket and sleeve gear is. I put the chain on it and drilled the chain into my workbench and the screws still ripped out and the case turned in the vise... 80ft/lbs is a lot!

That screw is a real PITA I tried to get it in on the sprocket before it was even on the gearbox and an hour later it still wouldn't go. I think I must have gotten the wrong size or something!

The answer is yes. PITA is correct. It has to be at the perfect angle. I'm sure it took be an hour to get that thing in. :mrgreen:

The best way i have seen is with the gearbox installed and a socket in between the swing arm tube and a sprocket tooth.. I have an electric impact wrench which saves headaches in many ways. 80ft/lbs is a lot so purhaps a little less and line up the other screw will do. That's what it there for.

As far as the screw goes, take a close look at the angle of the threaded hole. I believe it is neither level nor perpendicular with the face angle of the sprocket. Match it up perfect and it will start. Make sure the leading thread of the screw is nice and sharp and not rolled over.
 
Looks to me you have the lockwasher on upside down, not that the position matters, but if it's close, just tighten it a bit more, it'll go. 80 ft/lb.

The gearbox is at my dads office where a bigger vice will hopefully allow us to torque the nut.
In the meantime I got the stuck cam issue dealt with and got the timing case stuff done up.

Here's how I held the crank in place while I tightened the nuts. Credit to rich_j... thanks

Sorry for the crappy pictures, iPads aren't great for them. I also have no idea why they are sideways.

Matt
 
If you're taking the picture in landscape, it will be sideways when you post it.

You can download the PS Express (FREE) app to rotate them before uploading to your picture host if you want. Or just post them sideways and tell anyone who complains to eff off. :D
 
I took the pictures in portrait not landscape...its beyond me why theyre sideways. Heres a picture with the head on...annealed the copper gasket and nipped up the head bolts. She's lookin pretty nice. I'm excited to get the shiny rocker covers and timing cover on.

Annealed gasket:
How long does the copper stay soft after it is annealed. Just curious?

Lookin' great!

FWIW, I think the iPhone/iPad sometimes interprets the image and determines whether it thinks it's portrait or landscape. My phone seems to lag a bit as I rotate it around, thus enabling the possibility that my picture could be taken in an aspect other than how I would want it.

Either way, it's fine. :p
 
Photos can easily be rotated in Photobucket (click on the photo "Edit" then "Rotate" and either "Save a copy" or "Replace original").
 
keep this up Matt!!! thats one amazing commando you should be really proud of yourself its going to look brilliant when its all done really will bet you are buzzing :D

what paint did you use on the barrel?

Thanks,

Tom
 
Yeah Matt, crappy pictures are good enough to embarrass me to approach your level.

Thanks Tom
I controversially powdercoated the barrels with gloss black. Hoping that it all goes well.

Thanks hobot,
I'm anxious to get it rolling. The crappy pictures make it look better, they hide the imperfections :D
