Determining the thickness of adjusting washer “S4” l  Gasket ring for output flange removed. –  Press large outer ring/tapered-roller bearing for shank bevel gear with thrust piece -MP6-414/7 (3253/7)- from the assembly device -MP6-414 (3253)- into the secondary shaft housing → Chapter. –  Press small outer ring/tapered-roller bearing for shank bevel gear with thrust piece -MP3 458 (VW 472/1)- into the secondary shaft housing → Chapter. –  Position large inner ring/tapered-roller bearing onto the shank bevel gear.

–  Press small inner ring/tapered-roller bearing for output flange. –  Insert shank bevel gear. –  Fit the thickest adjusting washer S4 = 2.5 mm onto the shank bevel gear, assign via the → Electronic Catalogue of Original Parts.

–  Insert output flange with inner ring and position nut. -A- M 10 screw, screw in as support -B- socket wrench insert -C- protective jaws –  Tighten nut to 50 Nm, turn screw -A- back or release fully. –  Press shank bevel gear towards large outer ring/tapered-roller bearing and to do so turn eight times.

–  Set the dial gauge to 0 with 1 mm preload on “0”. –  Move shank bevel gear up and down -direction of arrow-. –  Read off play on the dial gauge and determine adjusting washer S4. Example:

	Adjusting washer	2.50 mm
-	Compression (constant value)	0.20 mm
-	Play (read off the dial gauge)	0.35 mm
Adjusting washer S4=		1.95 mm

Note Assign the adjusting washers via the → Electronic Catalogue of Original Parts. Available adjusting washers for S4

Adjusting washer thickness (mm)
1,30	1,65	2,00	2,35
1,35	1,70	2,05	2,40
1,40	1,75	2,10	2,45
1,45	1,80	2,15	2,50
1,50	1,85	2,20
1,55	1,90	2,25
1,60	1,95	2,30

–  Install determined adjusting washer S4 instead of the 2.50 mm thick washer. –  Screw secondary shaft housing with a temporary adjusting washer S3 onto the final drive housing.   Note When fastening the secondary shaft housing, an adjusting washer S3 (e.g. 1.2 mm) must be inserted, thus the shank bevel gear should not rest directly at the final drive housing.

–  Lock output flange for angle gearbox with stop plate -T30097/1 (T10108/1)-. –  Screw the nut for the output flange onto the shank bevel gear and tighten to tightening torque → Chapter. -A- socket wrench insert with 3/4 inch drive l  Drive shaft with head bevel gear is removed.

–  Measure friction torque. -A- torque gauge 0...600 Ncm -B- socket wrench insert -C- adapter of 1/2 to 3/4 inch Following friction torques must be adjusted:

new bearings	used bearings → Note
100…240 Ncm	30…50 Ncm

1)  in service for at least 50 km If necessary correct by a thinner (more friction torque) or thicker (less friction torque) adjusting washer S4.
