VW385/3 plastic piece faces final drive cover
-
Install cover for final drive and tighten four bolts.
-
Using adjustable ring, pull 2nd centering disc out far enough, so that the mandrel can only just be turned by hand.
Determining dimension "e"
-
Turn measuring mandrel until dial indicator plunger tip touches end gauge on pinion shaft head and measure the maximum runout (return point).
Measured value is dimension "e" (red numbered area).
^
Measured value in the following example: "e" = 1.60 mm
Note: Dimension "e" is required to determine thickness of S3 shim.
-
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. If not, repeat measurement.
Determining thickness of shim "S3"
Formula:
"S3" = "e"-"r"
e = determined value
r = deviation (indicated in 1/100 mm on ring gear)
Example:
determined value "e" 1.60 mm
Deviation "r" 0.42 mm
Thickness of shim "S3" 1.18 mm
-
Determine shim as closely as possible according to table.
