-
Remove master gauge and install measuring mandrel into transmission housing.
-
Dial indicator extension -A- = 6.5 mm long must be installed
-
VW385/3 centering disc faces cover for final drive
-
Install differential cover and tighten 4 bolts to 22 Nm (16 ft. lbs.).
-
Using adjustable ring, pull 2nd VW385/3 centering disc out as far as possible, so mandrel can only just be turned by hand.
Note: For transmissions with drive flange without polygon bearing use VW385/2 centering disc instead of VW385/3 centering disc opposite dial
indicator.
-
Turn mandrel until dial indicator plunger tip touches end gauge on pinion shaft head, measure maximum runout(return point).
-
Measurement in following example "e" = 0.26 mm (red scale)
Note: After removing universal mandrel, and with VW385/30 master gauge in place, check dial indicator again to see if it indicates "O" with 2
mm preload, otherwise correct adjustments.
Determining thickness of shim "S3"
Formula:
S3 = S3*+r-e
(-e- in black scale)
or
S3 = S3* - r-e
(-e- in red scale)
Notes:
-
The deviation "r" (tolerance) related to the VW385/30 master gauge "Ro" is measured for the final drive sets supplied as replacement parts and
marked on the outer circumference of the ring gear.
-
If measurements are based on red scale, subtract value "e."
