Determining the Thickness of Snap Ring 20
This procedure must be carried out if any of the following
components have been renewed: spindle 2, flange 3, gear
assembly (items 4, 5, 9, 22 and 23). The procedure, referring
to only one crankshaft 9, should be repeated for all three.
1 Lightly tap the outer ring of bearing 22 installed on
crankshaft 9 of gear assembly H, using press jig J and
a hammer to make sure the gear is fully seated in
spindle 2.
2 Install the thinnest snap ring 20 into the snap ring
groove in flange 3.
3 Lightly tap the outer part of the snap ring with the press
jig and a hammer.
4 Use a feeler gauge between snap ring 20 and bearing
22 to measure the clearance.
5 The required snap ring thickness T = feeler gauge
thickness + thickness of snap ring installed ± 0.05 mm
(0.002 in). Select a suitable snap ring from the twelve
detailed below.
