Engine tear down, Engine help Options

Also, when you do assemble and install the cam, pay special attention to those bolts to make sure you have clearance against the case. I'm not sure how often it happens, but I had a small clearance issue that required some minor grinding on my part to make sure everything rotated cleanly.

Good luck. Getting it back together and hearing it fire up (and not blow up) is very satisfying (IMG:style_emoticons/default/beerchug.gif)

So I am now starting the rebuild after the tear down, cleaning, new parts, testing, etc....One question, I am putting in new barrels, pistons and cam, pins, bearings etc, but keeping the original crank which was tested and is in good shape. In addition, all 4 crank rods checked out. However, I assume I should replace the 4 round bushings at the small end of the rods. From what I have read, this isn't a do-it-yourself home job, but instead should be done by local machine shop. Am I correct?

Ohhh man...that engine stand is a recipe for disaster. (IMG:style_emoticons/default/blink.gif)

Those cheap engine stands are crap, over on the samba a guy sells reasonable priced 3 arm stands.
And I hope that bench is screwed to the wall. As soon as you add the weight of the crank and P&C's the whole thing, bench and all, will fall on it's nose.

No, it won’t. There is an Alfa Romeo engine inside the crate. And I’m only using it to do one half.

Yep not DIY,I have found these stand up fairly well but with piston pins worn on cold start you hear a noise like ticking it soon go's away after the engine warms up.
The new lubed piston pins should be a firm push to pass through the rods.
Best to replace,EMW have speced rebushed rods for a great price ,last time I checked it was $55 for 4...excellent value from a good shop and most likely cheaper than the small end bushes to fit and ream somewhere else.

Have you had the case checked and / or decked? 50 years on, there's a good case that the registers need to be trued up. Usually on the 3/4 side. If the registers are off, the head won't seal to the cylinders properly and you'll have to tear the whole thing down to fix it. I'm going through this right now on a 2.0 engine. #4 register is .020 out. Ugh.
