• About to buy engine bearings.... by Barry W on 05 Jun, 2007 22:16
• I need the link to the main bearing mod that I had seen a few months back. Anyone got that? Done it?  Or give me any tips or quick referance?

• The "mod" is just that you buy the 6 piece main/thrust bearing and reuse the old thrust bearings so you don't have the machine them because they are already set for that engine.
  
  This is what you want (for a 1.6 TD)

  NOT THIS (which has the thrust bearings built into the main bearing)

• Why would re using the old Thrust Bearings be better than using new ones of the same size?

• Bit of a "religious" debate... the old-style thrust bearings are built using 3 separate parts and have about twice the thrust surface area of the new bearing design (one part with an integrated lip on both sides).   There have been some reports of the new design self-machining the crank surface.... the idea being half the surface area equals double the force on the crank.
  
  So, some people buy two sets of bearings, toss the thrust bearing, and re-use 2 of the 3 pieces of the old thrust bearing along with a new shell.

• well i think all that i am going to do is make sure i put the bottom end back together the way it was originally (if the bearings that the machine shop buy look any different, then they will not be going in..).. i mean it's been driven for 130'000km or so and looks good to me!
  
  all this thrust washer and bearings not to buy... hmmmm
  
  so I need 4 thrust washers correct?
