MAINTENANCE/ADJUSTMENTS
DRIVE CHAINS Checking the Drive Chain Tension Check the tension of the four drive chains after the first 250 hours of operation on a new machine or new chains. Then, check the tension after every 1000 hours of operation. 1. Lower the loader bucket or attachment to the ground. Turn the key switch to OFF and stop the engine. 2. Use a jack or hoist and lift the ma ch ine. Install blocks or a xle stands under the machine. 3. Clean the area around both inspection covers and remove.

9. Move the chain up and down and measure the deflection as close as possible.
1. DRIVE CHAIN INSPECTION COVER
IMPORTANT: If the deflection is more than 40.0 mm (1.5 inch) total movement for one chain, adjust the deflection of all chains. See Adjusting the Drive Chains on page 172 of this manual.
4. Sit in the operators seat and pull the seat bar down.
10. Repeat this procedure on all four of the drive chains.
5. Start the engine.
11. Apply sealant between cover and chassis.
