Rear Axle Toe In; Transition Drive Chain - Hillco 2970H Operator's Manual

REAR AXLE TOE IN

If the rear tire and wheel size changed after the proper sized rear tires were installed the toe
in should be checked. Consult your combine's operator's manual on the correct toe in for
your tire and wheel size.

TRANSITION DRIVE CHAIN

Check to see that the transition drive chain is in proper alignment and has proper tension.
Misalignment of these sprockets will cause premature wear of the sprockets and chain.
Chain tension is maintained with the tensioner that is bolted to the right side of the transition.
Tensioner adjustment can be found in the following paragraph.
CHAIN TENSIONER ADJUSTMENT INSTRUCTIONS
Step 1
Adjust the tensioner to the correct degree of tension by first placing a wrench on the square
portion of the tensioner body and loosening the mounting bolt with a second wrench.
Step 2
Apply pressure to the tensioner body in the appropriate direction until the chain is properly
tensioned. (See Figure 1) Note that the tensioner is designed to deflect up to 30 degrees
either side of its normal position.
Step 3
While holding the tensioner body in position, torque the mounting bolt to 60 lb ft.
Step 4
Before starting the drive, check the nuts on the idler bolt for tightness.
Step 5
After the drive has been started, visually inspect the tensioner for alignment and proper
tensioning.
