Dimension "a" = 28.5 mm
With a depth gauge, measure from the housing to the bearing surface of the ball bearing. See Fig 3 .

Dimension "b" = 26.8 mm
Measure the thickness of the lower snap ring (No. 8, in Fig. 30 in DISASSEMBLING AND ASSEMBLING TRANSMISSION G 86 ).
x = a - b

= 28.5 - 26.8 mm

= 1.70 mm

Measure the thickness of the snap ring in accordance with the table:

SNAP RING THICKNESS SPECIFICATIONS - INPUT SHAFT

Measurement result (mm)	Thickness (mm)
1.48...1.56	1.54
1.57...1.65	1.63
1.66...1.74	1.72
1.75...1.83	1.81
1.84...1.92	1.80
1.93...2.01	1.99
2.02...2.10	2.08
2.11...2.20	2.17
2.21...2.27	2.25
2.28...2.35	2.33

Force the snap ring and ball bearing onto the input shaft with the special tool 30-100.
Determine the thickest snap ring which can still just be used.
