Installation Tips
Avoid excessive misalignment between the engine and power take-off. Check the fol-
lowing if abnormal wear of parts exists:
Verify the power take-off is properly lubricated prior to starting the engine. All
serviceable points have a hydraulic ("zerk") grease tting. See lubrication in Main-
tenance for more information. Improper lubrication will result in premature failure
of components.
Verify the clutch is adjusted according to the procedure outlined in Clutch Adjustment
in Maintenance. Failure to do so will result in premature clutch wear and failure.
NACD will not be responsible for any damage or injury resulting from improper ad-
justment and/or lubrication. This includes any accessory drives and loads.
Excessive loads tend to deect parts to which power take-offs are mounted. A dial
indicator can be mounted on a rigid part of the engine or independently on the foun-
dation to determine deection under actual operating conditions.
Readings taken before the drive is installed with the engine standing still and when
under operating conditions will indicate the extent of deection. In no case should
the deection exceed .010" at the bearing carrier. See Figure 6.
Avoid excessive tightening of belts or chains. See Table 5 for allowable side load
information.
