Snubber Gap Measurement

SNUBBER GAP MEASUREMENT
The gap between the snubber face and the top of the chain should be 0.0 - 0.030 inch with chain slack removed. The gap can be adjusted by installing snubbers with different off-set mounting holes. The amount of off-set the mounting holes has, will determine the position of the chain snubber.

The snubbers can be identified by their color. There are three different snubber colors available (black green and tan). The black snubber will give the most clearance between the chain and the snubber face. The green snubber will give the least clearance between the chain and the snubber face. The tan snubber is the nominal snubber.
1. Insert screwdriver into the 18mm hole below the chain and pry up on chain to remove slack in chain.

2. Using a feeler gauge, measure the gap between the snubber face and the top of the chain (Fig. 306).
3. If the measurement is not within specifications, install the correct snubber as required.
