Transfer Chains Length Measurement

The need to replace the transfer chains because of excessive wear is unlikely. If chain length is suspected to be long, perform the following procedure to measure the chain length:

Fig. 439:

1. Insert a screwdriver into the 18 mm hole with the screwdriver ABOVE the chains (Fig. 439).
2. Pry the chains down at the center of the chains.

3. Butt a scale against the snubber and mark the scale at the bottom of the chains (Fig. 440).

4. Insert a screwdriver into the 18 mm hole with the screwdriver BELOW the chains (Fig. 441). An assistant may be needed to perform this step.
5. Pry the chains up at the center of the chain.

6. Butt a scale against the snubber and place a second mark on the scale at the bottom of the chains (Fig. 442).

7. Measure the distance between the two marks placed on the scale (Fig. 443). If the two marks on the scale are more than one inch apart, replace the drive chains.
