DRIVE CHAIN 3.3
Checking The Drive Chain
The drive chain must be checked for adjustment after the
first 50 hours of service and every 150 hours thereafter.
Correct chain tension must be set to 1/4 to 3/8 inches (6
to 9mm) free play.
1 Remove any attachment, raise the boom arms and
engage the boom support pins. Shut off the engine.
2 Remove the small inspection cover located to the rear
of the steering lever. (fig. C2024)

4 Check the chain tension using the special tension tool
P/ N 960997. Slide the special tool into the filler hole and
use the hooked end to grab under the chain. (fig. C372)
Pull upward on the tool using a force equal to approxi-
mately 30 lbs (13.6 kg) pull. The special tool is calibrat-
ed in 1/4 inch increments. (6mm) Correct adjustment is
calculated by the number of marks the special tool moves.
The special tool should only move 1/4 to 3/8 inches (6 to
9mm) at a 30 lbs (13.6kg) pull. Replace the plug if no
further adjustment is required.
5 Apply a thread sealant to the inspection / fill plug
before replacing. (fig. C2279)
