Finished adding all the bits to the engine, carbys, dizzy hoses etc etc.
Attempted to get some washers behind the plate, however not enough space. Keeping the plate near the end of the cam there is very limited space. Had another person hold onto the outer edge (chain) and lightly tapped the plate outwards (toward the front of the engine) with a piece of 1/2 inch copper pipe used as a punch, without success. The parts seem to be locked together, solid.
Using the marks on the harmonic balance plate I measured the position of the inlet cam when the slot in the cam is in the correct position. It is 12 degrees ATDC, which equates to 6 degrees of cam timing.
Calculated by measuring the distance between the TDC mark and 10 degree BTDC mark around the permitter edge at 20mm (approx), so 2mm = 1degree. Then measured the position on the crank pulley when the inlet cam slot was lined up correctly, this I measured as 24mm, which equates to 12 degrees
If my calculation is correct the inlet cam is late by 6 degrees.
Before the head work, the car was driving OK, and when removing the head I noticed the cam timing was out of sync. Now with the work completed, new reseated valves , etc I am reluctant to crank over the engine. However, I have turned ithe engine over manually using a spanner on the crank pulley, and everything turns OK.
Any other suggestions regards separation of the plate and chain (sprocket)…or is the 6 degrees of late Inlet valve timing ATDC not going to make a much difference???
Paul, yep I am extra careful when working around the front of the cams. On disassembly, without thinking clearly I snipped off the safety wire and a piece dropped into the “cavern”. Luckily the piece landed on a bit of a ledge, so using a magnetised screwdriver was able to extract the piece of wire…sometims luck is on your side, also learnet a great lesson.
