This time with stripped threads in the crank-case.
The engine is cleaned out and back together ready for it’s test run.
Here is the Laser 90 ready for testing.
Before and after timing case.
Starting to look more like an engine again.
There is some play in the “big end” but I am not, at this moment, set up to replace the bush in the con-rod. I am just being picky here, the engine should have a new lease on life with the new bearings and piston rings.
One of the piston rings in the bore to check for fit.
The ends of the ring must have a gap, seen to the left side of the picture, to allow for expansion when hot. I think .005″ will be OK.
Pressing the bearings back in to the crank case and crankshaft housing.
Bearings came out fairly easily using a car wiper arm removal puller.
