Ive searched for 1 hour now..

Search feature owns me!

what are the tolerances for our main bearings?

for some reason mine were speced to 0025, 0024,0025,0024,0025

 

.024-.048mm and .0009-.0019in

 

my bad.....that was for the main bearings.....give me a second and ill get you the rod bearing specs

 

nvm...ignore last post....the numbers i gave you are right.

 

nvm i was asking about the main bearings anyways!

are having them so loose bad? also you see the crank? i had the oil holes chafered out so additional oil could be slinged around the rod bearings!

 

.017-.040 is the recommended oil clearance..........having loose main bearings is bad..........go on ahead and put a leash on the crank and take it for a walk........go to calico.com and get your bearings......there calico coated ACL race bearings and are the cheapest place i could find them

 

mike....txt me if you need anymore info or anymore questions.......my internet is fu<kin up

 

are they .0025 in INCHES or MM?.....inches are .0007-.0016

 

im guessing inches, since they say 0025, 0024.


He told me now to run 10w40.. maybe he speced this motor for this oil? i dunno GRRR

 

son of a mother ******......ok.......

Rod bearing oil clearances
IN.0009-.0019
MM.024-.048

Main bearings
IN.0007-.0016
MM.017-.040

 

So my motor is out of spec!

Tommrow i will call p-tuning maybe one of those guys will have some info for me! i know they did alot of testing on this! hopefully these guys chose this clearance for a reason! i have alot of money into this motor now

 

i hear ya man.......you are torqing the main caps to spec right? 30ft lbs then 90 degrees

 

I used ACL race bearings (std size) and they were a tad over spec. I used Dart Machine in Troy, MI for my coatings and they can coat them to whatever thickness you need.


I have mine on the tighter side of toyota spec for both the rods and mains

 

i think mine were just a tad over spec........like say they were supposed to be .025....mine were .027 at the most.......

 

im not assembling the motor.. CFT is. im going to call today

 

Don't use OEM main bolts. Get ARP studs and have them align bored the block. Send you head to RLZengineering. The do the head work for most of the big team, like Tony Palo and Leslie Durst...

I set my clearances to 19 to 21 on both my main and rods. using calico coated ACL. I decided that after talking on the phone with Horizon motor sports (scion team).

 

lol....yea mike dont use oem head bolts.....geez.....NNNNOOOOOOOOOOOOBBBBB

 

if you could read, I said MAIN bolt... HENCE getting an align bore.

Nice try

 

NOOOOOOOOOOBBBBBBBB(to me)...........i used my oem main bolts.......there not tty so you can reuse them.

 

the motor was aline bored.. crank is fully balanced. each rod is fully balanced from heavist to lightest rod. basically a fully balacned rotating assembly. bs removed. carrila a beams je 9-1 pistons race bearings arp head studs
