6.2 V8 Chev diesel

Recommended Posts

I was helping a mate pull one of these motors out of his Toyota Landcruiser yesterday 

Anyway we pulled the motor right apart and his son who is engine machinist is going rebuild it

After we had it all apart I was watching a YouTube video on these motors and it says that the push rods are harder one end than the other and to mark the push rods as they come out 

Well we never did oop's 

Does anyone on here know of a way pf checking push rods to find which end is the hard end ?? And if not , how critical is it with push rods ????

The You tube  video that mentions about the push rods

 

Any advise or help appricated

If they really are different, GM should have marked the harder end. I don't know a thing about the 6.2.

If Volvo has good sense Paul, they’d make you head of Mack brand sales marketing. You have the gift.

I found this description for the pushrods

This pushrod has an actual length of 8.845 inches. It is made of .375 diameter steel tube. It is tipped with one welded .375 diameter M-4 tungsten steel ball (copper flashed with hole) and one welded .375 diameter steel ball (with hole).

According to this description the copper flashed end is the hard end.

How long the copper will last is anyone's guess but they are probably really just worried about the assembly line

 

The copper lasts long enough to set a matched wear pattern to each rocker arm point. GM suggests that you keep them in assembled order to the rocker and the lifter. Don't know many who do that, even GM techs.

The hardened ball is supposed to save them both from damage/ excess wear of the push rod and rocker from miss adjusted valve lash. GM learned that with the first gen Olds and Caddy diesels.
