I looked closer at a few of the markings.
I don’t know what this stuff means.
In 2004, I had a recently rebuilt 440 throw a rod so I bought this block to replace it. It is a 1974 casting.
I tried to fit the Lunati cam in. It cleared the first three bearings but stopped at #4.
I pulled out my trusty cam bearing clearance tool:
I packed the cutting grooves with bearing grease and slipped it in. It stopped at #4 bearing too so I slowly rotated it until it went in…then it stopped at # 5. I spun it some more but it wouldn’t move in anymore. Using a rubber mallet, I tapped it in.
From there, I spun it until it moved freely.
When I pulled the cutter cam out, I saw this:
#3 bearing moved to the rear. I was able to get it back in place with a paint stick and mallet but then I found the bearing was loose in the block.
I’ll have to take the block back to the shop to have my guy replace the one bearing.
Weird story…. Thursday the man called to say that the rearmost bearing wouldn’t stay in place. I bought another set of cam bearings and brought them in. Now #3 is doing the same thing.
