Determining shim -A- –  Install all components ( → Item to → Item) to adjust planet carrier into gearbox housing → Item.

–  Insert screwdriver through holes of “large sun gear” to loosen and tighten “bolt for small input shaft”.

–  Install bolt for small input shaft -1- with washer -2- without shim. Torque setting: 30 Nm –  Insert dial gauge in -VW 382/7-.

–  Set up measuring instrument with dial gauge tip positioned on bolt head centre with 1 mm preload. –  Zero dial gauge. –  Press small input shaft up and take reading. Example: Measured value 2.00 mm –  Ascertain thickness of shim according to table and determine part no. from parts catalogue. Table of shims:

Gauge reading (mm)	Shims (mm)
1.26 … 1.35 1.36 … 1.45 1.46 … 1.55	1.0 1.1 1.2
1.56 … 1.65 1.66 … 1.75 1.76 … 1.85	1.3 1.4 1.5
1.86 … 1.95 1.96 … 2.05 2.06 … 2.15	1.6 1.7 1.8
2.16 … 2.25 2.26 … 2.35 2.36 … 2.45	1.9 2.0 2.1
2.46 … 2.55 2.56 … 2.65 2.66 … 2.75	2.2 2.3 2.4
2.76 … 2.85 2.86 … 2.95 2.96 … 3.05	2.5 2.6 2.7
3.06 … 3.15 3.16 … 3.25	2.8 2.9

Example: Gauge reading 2.00 mm = Insert 1.7 mm thick shim. –  Remove small input shaft bolt.

–  Insert correct shim -3- on small input shaft -arrow-. –  Tighten bolt for small input shaft -1- with washer -2-. Torque setting: 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 planet carrier was adjusted with reverse gear brake -B1- and freewheel removed, reverse gear brake -B1- must be installed before installing planet carrier → Chapter „Assembling planetary gearbox“.
