I'm having a bearing meltdown

[Chasz86]

Hi all so I have hit a wall with my build, checking the repair manual it states that there are 5 sizes of crankshaft bearing and 5 sizes of connecting rod bearings, using the manual I have determined that I have for con rods: 333333 arrangement determined by cap and crank numbers. The crankshaft bearing I have 3222233 determined by imprint on the bearings.

 

Problem is ringing Toyota they only list a bearing kits crank = (13204-46023) and con =(11704-46030) no size detailed for either, they have 5 individual bearing listed but they all have the same code =(11071-46020-03). Can anyone shed some light on this? I was hoping to get some oem precision on the internal rather than aftermarket plug and play but quickly looking like it's the only option I have

Hi mate. If you give paul a ring over at TCB performance he will be able to supply you with the correct size bearings at a very good price.

 

If you are looking at going aftermarket, however, you can get the crank and caps measured at a machine shop to ensure they're within factory tolerances, and they should be able to tell you whether to go for oversized/standard size bearings, which is 1 size fits all. Then as a second check use plasti-gauge to measure oil clearance when reassembling. From what I've read, the factory numbers on the caps and block are garbage unless the engine is brand new anyways. Best off getting it measured IMO.

 

Hope this helps

Thanks for that advicei think I will get it professionally measured, also probably give Paul a shout.
