Chassis weigth is 4960......maximum load 8500....... good load for a 15cwt truck.

I took photos as being faster than finding files. The unattached plate is courtesy of Bob Carriere, comes from a cab 11 or 12. The plate on the brown background is facing the driver on a Chev Cab 13 doghouse.

Been for a little drive in the C8 up/down the road.

Lack of power was noticed . I discovered , the timing was retarded by quite a lot, so a quick twiddle of the dissy fixed that .

I connected my old vintage ECHLIN vacuum gauge to the wiper motor pipe , it shows 20" of vacuum at idle , with a steady needle on the gauge and a blip down when I rev the engine . So I guess that's a good sign .

I've always had a strange squeaky noise coming from the engine , I thought it was bad generator bearing ? Well turns out it's the fan belt . The modern fan belt V section does not match the old V ways exactly , it rubs on the sides of the V . I think I will try a Industrial B section belt .

I'm not an expert - but I thought V-belts did run on the sides of the V, not on the bottom?

In my case, the V angles of the belt and pullies don't match as I have already stated

Been doing some more testing. The valve rockers appear to be running dry, I can hear the noise of rattling valve springs . A peek in through the cap in the rocker cover reveals no oil anywhere . There should be some oil in there surely ?

Maybe the oil line coming up through the block to the rocker shafts is blocked ?

I will have to unscrew the pipe at the shafts and see if any oil comes through .

Rub some soap on a squeaky belt and it will stop squeaking. Liquid soap works too.
