Determine thickness of thrust plate (34):

1 Attach synchronizer body (25), bearing sleeve (31), thrust plate (34), bearing sleeve (35) and the synchronizer body (39) onto the plug gauge (42).
2 Check the protrusion (A) of the plug gauge.

se thrust plate (34) with the appropriate thickness if the protrusion (A) does not match the specified value.

Thrust plates with 5.70 to 6.15 mm thicknesses and a graduation of 0.05 mm are available.

3 Remove synchronizer body (39), bearing sleeve (35), thrust plate (34), bearing sleeve (31) and the synchronizer body (25) from the plug gauge (42).
