flyby Posted May 14, 2008 Share Posted May 14, 2008 Hey I new conrod bearings on my old engine. I look on the size of every conrod for the bearing size. On one side it say 2 1 on every one and on the other side it say 2** ** = kb, vb, wb, gb, gb, pb Like 2KB and so on. Is it then size 2 ?

Scooter Posted May 14, 2008 Share Posted May 14, 2008 Hey Is it then size 2 ? This is per my toyota manual First - if you have not yet undone them then there will be a mark on the old bearings themselves (1-5), so you could note this as you go. if they are off the engine you need to add this '2' to the figure stamped into the crank for each one. So you will need size '2' bearings only where the crank is stamped '0', size '3' if the crank has a '1' stamp and size '4' if the crank has a '2' stamp. Basically try and find these 6 stamps on the crank and add 2 to each one to give you the bearing sizes you need. Disclaimer! - this is me reading the manual, if you haven't dismantled the conrods yet then i'd be interested to see if the number stamped in the bearing you remove does indeed equal the some of the crank and rod numbers.

Yes this goes for the Main bearings, Thay are all marked "3" and "4" But the conrod is only marked outside the the conrod. Inside thay is not marked. The have a part no, that toyota cant use for anything.(thay say) if they are off the engine you need to add this '2' to the figure stamped into the crank for each one. So you will need size '2' bearings only where the crank is stamped '0', size '3' if the crank has a '1' stamp and size '4' if the crank has a '2' stamp.

It is not eazy to understand the manual on this matte. Quote Link to comment Share on other sites More sharing options...
