Title: inside of diameter rear main bearing cap/holder
Post by: impaw on 20 January, 2020, 08:00:11 AM
hello all :)

Do anyone have the inside diameter for the rear main bearing cap/holder of a 4ths series 2,5litre B20 engine?
From factory, that is.

There ha been some previous damage to the engine so my builder is trying to establish correct data.

From an old post of mine regarding main bearing caps. These are still available.

The first set of 4 is from B20 3142 shell bearing
The second set of 4 is from B20 3079 shell bearing

Any help to you?I
Chris

Thank you Chris,

I will have a talk with my builder.
I am not very adept at engine bulding, but as I understand from my builder, he will try to line bore the engine case(?)-
So he was curious what the original dimensons of the bearing holders was.

I will have a talk to him, perhaps he might as well replace the caps.

thank  you Chris!
