→ Determining shim -A-

• ‒ Install all components (items 37-106 .

• ‒ → Insert screwdriver through hole of "large sun gear" to loosen and tighten "bolt for small input shaft".

• ‒ → Install small input shaft bolt -1- with washer -2- but without shim.
       Tightening torque: 30 Nm.

• ‒ → Set up dial gauge so that top of gauge is positioned on bolt head centre with 1 mm preload.
• ‒ Zero dial gauge.
• ‒ Move small input shaft up and take reading.

Example: Reading 2 mm

• ‒ Specify thickness of shim according to table and determine Part No. from parts catalogue.

Table of "shims":

Example:

Measured value 2.00 mm =

Insert 1.7 mm thick shim.

• ‒ Remove small input shaft bolt.
• ‒ → Insert correct shim -3- on small input shaft (arrow).
• ‒ Tighten small input shaft bolt -1- with washer -2-
       Tightening torque 30 Nm.
• ‒ Carry out planet carrier check measurement.

Planet carrier check measurement

• ‒ → Insert dial gauge in VW 382/7 and place the tip on the bolt of the small input shaft.
• ‒ Move small input shaft up and down and take reading of play on dial gauge.

Play:

min. = 0.23 mm

max. = 0.37 mm

If the planet carrier has been adjusted with reverse gear brake -B1- and free wheel removed then before installing planet carrier install reverse gear brake -B1-, => Assembling planetary gearbox, Page 37-91 .
