1.Loosen the pillow bearing bolts only to the point where the bolts will remain snug.

2.Unlock the two pusher bolt lock nuts.

3.Turn each pusher bolt clockwise an equal amount until the chain is to proper adjustment of approximately 3/8" to 1/2” slack in the chain. It is very important that the pulley side and the chain side (pillow block bearings) are within 1/16” of an equal distance.

4.This distance can be checked by using a tape measure or a straight edge ruler, measuring from the inside of the pusher bolt bracket to the face of the pillow block bearing.

5.The drive chain should be adjusted regularly to remove all slack. Once all slack is removed, do not over-adjust, as this will overload the shaft bearings. A slack chain on the crank drive creates backlash and shock loads on the shafts and bearings which results in shorter wear/life of the drive components. Lubricate the chain regularly. Note-it is advisable to carry a spare chain and master links for replacement in the field if necessary.

6.Drive belts should be regularly adjusted to prevent slippage. To adjust the belts, loosen the engine mounting bolts and move the engine until there is a maximum 3/4" deflection in the belts, retighten the engine mounting bolts.

7.Frequent inspections should be made on all drive components to make certain that all bolts and nuts remain tight.

NOTE: PRIOR TO ADJUSTING CHAIN — PLACE THE LOBE OF THE CAM IN THE DOWN POSITION. THE CHAIN SHOULD HAVE 83 RIVITS INCLUDES (ONE EACH, HALF LINK AND FULL LINK)
