Where the rocker arms ride is the same, but where they go into the head is different. On engines that have been torn down a few times the holes often end up slightly oversized from fitting the wrong pins.

No LM.

I just measure them. There's an easier way?

Look at the size of the oil hole in the middle.
Ya will see 2 sizes.
The larger is the intake and the smaller is the exhaust. ......................lm

For years I would put them end to end and one day I noticed the difference at the holes and that made things easier/quicker. ........lm

rocker shafts

Post by pc13cb92 » Fri Aug 13, 2010 3:37 pm

Hi, just joined forum. Been looking for this info on the valve rocker shafts, as I have just taken my spare C72 motor to pieces in order to do a check and rebuild. I took out the shafts whithout realising they were different!
This spare motor was in a right mess - someone who did have a clue had had it to pieces before I bought it, and totally butchered it.

I recommend ya put the left side parts on the right and vice versa. .......lm

I TRY to pay as much attention to a part's location and special features etc when I'm dismantling, but sometimes I get too caught up in the act and my attention to detail suffers. There's a learning curve here, that's for sure, but I'm getting better all the time. At least...I hope I am.
