NOTE: Care must be used not to bond the bearing, next to each OPC hub, to the cross shaft which could cause binding of the OPC levers and erratic operation.
b)Fuel tank studs where studs are inserted into tank.
NOTE: When installing the nuts onto the fuel tank studs, fully tighten the nyloc nut and back off 1/2 turn. This allows for normal fuel tank expansion and contraction with changes in temperature and fuel levels.

5.2ADJUSTMENTS
IMPORTANT: Disengage PTO, shut off engine, wait for all moving parts to stop, and remove key before servicing, cleaning, or making adjustments to the unit.
5.2.1Cutting height and
CAUTION
POTENTIAL HAZARD
♦When mower deck is not installed or the two front support rod hairpins are removed, the unbalanced weight of the tractor or tractor with mounted mower deck support frame may cause the front of the unit to rise suddenly.
WHAT CAN HAPPEN
♦If the unit rises suddenly, injury may occur.
HOW TO AVOID THE HAZARD
♦Securely hold down the front end of the unit when the mower deck is not installed or front support rod hairpins are removed.
a)Stop engine and wait for all moving parts to stop.
b)Install hairpin clips in the holes for the desired cutting height. See Figure 9.
IMPORTANT: To maintain correct cutting height and rake, check the following for proper adjustment.
1.The front and rear hairpins are in the same holes with the proper spacers under the hair pins. See Figure 9.
2.The tire pressures are set as directed in Section 5.1.12.
3.The length of the rear deck support link assemblies should average 6.89” (approximately 6 7/8” (17.5 cm)) from the center of the balljoint to the center of the farthest hole. See Figure 9.
NOTE: All (4) pins must equally support the weight of the deck. Adjustment in the length of the rear deck support assemblies may be necessary. If one side is longer than 6.89” (17.5 cm), than the opposite side must be shorter by the same amount.
