18 PROPELLER SHAFT Assemble tube shaft and slip yoke, making sure that the alignment marks are in line. This will ensure that slip yoke lugs and tube yoke lugs are in line. Fig.28 INSTALLATION : PREPARING FOR INSTALLATION In propeller shaft assembly, when there is replacement of worn cross and bearing assemblies with a new kit, it is desirable to rebalance it. Take runout with entire drive shaft assembly mounted on master tooling which locates on the outboard bearing assemblies of the u-joint kit. All yokes should be selected for dynamic balance to eliminate as much unbalance as possible. During balancing, the drive shaft again should be mounted on the same master tooling or yokes. After straightening, balance the entire assembly to the specified limit. INSTALLATION ONVEHICLE Before installation ensure that : Splines should slide freely with slight drag from spline shaft seal. Cross should flex and be free from excessive bind. Note : A slight drag is the most desirable condition on a new cross and bearing kit. Excessive looseness is not desirable and will result in an unbalanced drive shaft. Mounting Flange should be free from burrs, paint and foreign substances which would not allow proper seating at assembly. While installing and servicing system balanced assemblies, The following rules should be strictly adhered to : End yokes must not be rotated from their original position during reassembly. FOR INSTALLATION PROCEED IN THE REVERSE ORDER OF REMOVAL. Tighten the mounting nuts 8 bearing strap bolts to specified torques. Caution : Self locking bolts used with bearing straps should not be reused. Fig. 28
