Could´t find it :s

Atleast on 3b the ideal measure should be 0.04.. I will order new bearings and some plastiguage..


Found it now.. 0.10 / 0.5mm radial clearance..

hmm.. that´s strange.. Could it be some other bearings ? When I search on the number I find this ones: http://martsources.en.alibaba.com/pr...Audi_Seat.html

I know that 034 is the code for AAN and I think 707 is the over size bearing number since 701 is the stock ones..

Could someone look up what audi´s uses this rod bearing with this number: 034 105 707

On a -92 AAN 034105707 is the yellow bearings with .25 u.s so just need to order new bearings

"034" covers a wide range, if not all, of the Audi 5 cylinder engines.

034 105 707 is the 0.25 mm undersize con rod bearings for a wide range of engines, including the KV, NG, NM, and 7A

For future reference:

034 105 713 = 0.5 mm undersize

034 105 719 = 0.75 mm undersize

Interesting that the last numbers go up by "6" with every 0.25 mm, i.e.
stock = 0.00 mm undersize = 701
0.25 mm undersize = 707
0.50 mm undersize = 713
0.75 mm undersize = 719

Hopefully that info will help some others to!


Here another question.. the piston ring gap - should the top one point towards the intake side, the second 120 deg clockwise and the oil ring another 120deg clockwise ?
