1 Measure and note dimension "D" of sealing surface from front section of transmission housing to cylindrical roller (arrow) of cylindrical roller bearing (21).
D26.50-0046-01
2 Measure and note dimension "A" from countershaft to the sealing surface of the front section of the transmission housing.
D26.50-0047-01
3 Measure and note dimension "B" from the upper edge of counter shaft to the collar of the bearing seat
4 Determine thickness of adjusting ring required (for specified value, refer to table)
Calculation example: Dim. "A" 179.7 mm - Dim. "B" 15.2 mm = Dim. "C" 164.5 mm
Dim. "D" 164.8 mm - Dim. "C" 164.5 mm = axial play 0.3 mm
Adjusting rings are available in thicknesses of 2.2 mm to 2.95 mm in increments of
0.05 mm

5.1 Remove locking ring (1) (up to transmission no. 006777).
As of transmission no. 006778 the countershaft bearing bore in the front section of the transmission housing is closed, the locking ring is deleted.
5.2 Remove roller sleeve using internal extractor (as of transmission no. 006778).

6 Remove adjusting ring (2).
7 Gently drive back roller sleeve (25) using a suitable drift punch.
8 Insert appropriate adjusting ring (2).
