Engine rebuild pt1...

With a clean cloth and some degrease solution I gave the block a good wipe down, removed any over-paint from the flanges.

Using STP oil I coated the big end shells and dropped the crank in to place, next the thrust washers again giving everything a good coat of oil. On with end caps and hand tighten at this point.

Checking the end-float of the crank came in just over half way between of the recommended tolerance.

Next the pistons, checking the ring gaps where at 180 deg to each other, I used a ring clamp to compress them and trapped the first one in. Again covering the small end shells with oil and hand tighten them - after each piston was attached I used the crank pulley to help rotated the crank.

STP oil is very sticky stuff and crank is fairly stiff to rotate - it's also very cold today and trying to snow again!
