Got a 2009 tc, spun a bearing. Got the engine apart already, crank seems fine, no scratches or nothing unusual. I drove the car only 10 miles home after I began hearing the knock. I found the rod bearing that failed, so I went to toyota to get a new rod bearing set (might as well get the whole set). Problem is, it doesn't fit. On the rod itself, it has the #2 , so that's the one I got from toyota. I went home, torque them down, and I was able to wiggle it slightly with my hand side to side, up and down it was solid. Is that normal?

Since I figured it didn't fit, I went back to toyota and ordered #1 and #3 bearings and again, none fit.

Am I going to have to take it to a machinist and have them resurface the crank and measure for new bearings?

Has this happened to anyone else?


It's my first time tearing down this engine. So any help will be much appreciated.

Thank you

 

Anyone?

 

If there was a spun bearing than there is going to be crank damage.

 

I checked the clearences of all the journal. They r all fine, except the one that spun. It's .0040 in, when recommended is .0015-.0020 in. What size bearing would I need?
Would it be a undersize .0025?

I'm not going for performance, just stock daily driver for a while until I sell it. Should that undersize bearing work long enough?

 

There's no other way to dice it, if you spun a bearing, the crank is damaged. I've rebuilt dozens of engines, especially Toyota and what you're doing is a vain attempt to save some money. Feel your pain brother but once the bearing is spun, you will HAVE to regrind the crank, get appropriately sized bearing and clean the hell out of your engine before reassembly. If you omit any one if these steps, you'll be tearing apart that motor within the next hundred miles.
