main. bearing caps

[sandwich1987]

Managed to source amother agu block for my eventual striker engine...but the seller hasn't included the main bearing caps, I've sent him a msg but if he dmeant have them can I use The ones I had from my other block or are they all individually line bored?
Chee're

If you uses different caps on another block it will need line hone

 

[sandwich1987]

Will that mean I have to use oversize bearings? Think it will probably be better to source a complete engine! Oh well another block for the scrappy

 

[Andrew@A.L.D]

No mate

The cap are machined at the mating face bring the the cap closer to the block if you know what i mean then they are torque down to the block then line honed to the standard size

Yeah I get what you mean, the height of the cap is reduced slightly.

i have managed to get in contact with the original seller of the block so i think im going to be ok and match the original caps....phewwwww. now i just need to wait for an agu/aeb head and then order all my stuff from IE. Andrew do you know if going for the 83mm bore, is it 83mm exactly that the machine shop bore it to? Or is the boring size/tolerance sent along the stroker kit? cheers

 

[Andrew@A.L.D]

No if you get a 83mm bore piston doesn't alway mean you get a 83mm piston

A machine shop will measure all the pistons and bore the block accordingly to each pistons to get the right piston to wall clearance.

pistons are usually .05mm smaller than the bore they are designed for

I have JE pistons and they are 0.1 undersize which is apparently normal for JE, so '83mm' pistons in my case are 82.90
