I have a 1999 s10,2.2l in the process of installing a. Crankshaft and bearings,

(1999 Chevrolet S10)
in Timberlake, NC on August 28, 2014
#3 main bearing is different from the others. This bearing will not let the crankshaft drop into position. It is the same size as the others but when installed it becomes too narrow at the sides. I checked measured everything. The #3 cap is narrower from side to side than top to bottom. Is this weird? How did it fit the old bearings and crank.

Did you get a 'complete crank kit'...??? IF so, check the casting numbers... The crank design was changed in the engine around the mid to later 90's... You may have the wrong parts! Compare the new (thrust) bearing to the old one while looking at the locking tabs on both!!

I got a new crank kit. Cast # is good. Bearings 1,2,4,5 are good fits. Thrust bearing is is good also. #3 is different. The locking tab are reverse of the other 4.

Couldn't remember which was the thrust... I tough it was # 3 Been awhile since I did an engine rebuild... However i knew there had to be some info on this as the parts store sent me the wrong crank... So here you go... Look over that whole page... Good luck!

I read this and zerode in on the part where they changed the tangs on #3. That's why it was different. The did send a bearing to match these tangs. What can cause "out of round" on mains?

Is the bearing going all the way down in the block and the bearing cap?... Locking tab going into the cutout? .. What happened to the old crank... It didn't break did it??

The bearings are going all the way down to the bottom. I did some more measuring. It seem the bearing for this #3 journal needs to be about .020 thinner. However, all journals are 2.485 od.

That's the reason I stopped f-ing with them!... No machinist around that's worth a crap anymore, can't get the right parts, just too many different problems with the same engines!... Back in the day, it was a breeze...but them days are gone!.. You may need to get another crank kit to get it right.... Bearing size should be stamped on the backside of the bearings... Just make sure the crank turns free after torquing each cap, plastigauge is a good idea!.... It's hard to be much help online!.. Really need to be standing there.. Good luck with it!!

Thanks so much for your help . I'm getting the feelings about this crap. People want to sell you stuff but they don't want to get it right.Bright
