Hi,

Thanks to this forum and Pindelski's web site. I did the valve lash adjustment on my 83 SD. The valves are all tight. Exhaust valves are around .25mm, intake valves are around .05mm and some are less. The CAM lobes have no visible wear. The chain stretch is around 0 to 2 degree. I think there will be some in-accuracy when measureing the chain stretch by the CAM and crank damper marks.

Well, most importantly, it runs much smoother and less vibration, less noise after the adjustment.

By the way, I have to grind down one of the bent wrenches which I bought from **************. The bottom nut is thinner than the thickness of the wrench.
