→ Determining shim -A-

• ‒ To adjust planet carrier, install all components (Items 1 to 9 and 14 to 18) in gearbox housing.

• ‒ Engage parking lock.
• ‒ → To slacken bolt for small input shaft, insert screwdriver in holes of large sun gear.

Note:

If the parking lock cannot be engaged, use a second screwdriver to hold the large input shaft.

• ‒ → Install bolt -1- for small drive shaft together with washer -2- but without shim -3-.
• ‒ Tighten bolt to 30 Nm.

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

• ● Reading in following example: 2.00 mm.

• ‒ Determine size of shim(s) according to table. Part Numbers

=> Parts catalogue

Table of shims -A-

• ‒ Remove small input shaft bolt.
• ‒ → Fit determined shim -3- onto small input shaft (arrow).

Example:

If the reading is 2.00 mm use a shim with a thickness of 1.7 mm.

• ‒ Insert bolt -1- for small input shaft together with washer -2-.
• ‒ Tighten bolt to 30 Nm.
• ‒ Carry out planet carrier check measurement => Page 37-140.

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.

Note:

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 37-113.
