1. Lightly lubricate the gearing of the armature shaft and the engagement lever bearing with grease.
2. Lightly oil the bearing and gear.

Battery connection method to test gear distance. Measure the gap between the arrows
1 - battery
2 - connected switch
3 - gear thrust ring
4. Starter gear, when current is applied, jumps forward onto the thrust ring (3), however, there must be a gap between the gear and the thrust ring. Measure this gap with a flat feeler gauge or caliper. If the gap between the arrows is greater than 3 mm, something is wrong in the starter.
