Inspecting Slack
Chain “slack” is the term for the amount of looseness a chain has. Chain “section” is the area of a chain between 2
sprockets shown as “C” in Figure-8. A common mistake occurs when the Mudd-Ox is on the ground, and mechanics
simply wiggle one section of chain to check its slack. This will not provide an accurate reading, as slack occurs in
multiple sections. The following measurements are approximations of total slack for each chain:
Front set (1 per each side): 1/4”
Rear sets (2 per each side): 1/2”
1. See Raising the Mudd-Ox under Jack Points. Although the parking brake is set, the wheels will be able to freely
rotate a few degrees. Because of this, slack is no longer in multiple sections of the chain - and can be inspected
in a single section.
2. Locate the chain you wish to inspect. Remove floor board, engine cover and/or seats as necessary.
3. This example will utilize the rearmost right side chain. You may now wiggle the chain up/down and measure
how much slack is present (Figure-10). If they are not the desired measurement, proceed to Adjustment. Note:
Chains can be sharp and potentially harmful. We recommend wearing protective gloves.
4. Repeat above steps for remaining chains.
