SPLINE SHAFT ASSEMBLY LAYOUT

1

Spline Shaft Assembly Critical Settings

CONE CENTER DISTANCE

As per the value etched on Pinion & bearing height SHIM = CONSTANT –(value etched on pinion face + value to measure)

Use special tool for measuring bearing height (bearing outer race top to inner race top)

Pinion Bearing Preload

1)Place the CCD shim as per selection.

2)Slide the inner race of the inner taper roller bearing with suitable dolly. Ensuring that the inner race firmly & squarely

3)Place ‘outer race” of the inner bearing, ‘Outer spacer”, Inner spacer few shims, ‘Outer TRB along with outer race, ‘Oil seal runner’ & ‘Crimping nut’. Use suitable pressing dolly.

4)Fix the Spline shaft on FIXTURE. Torque the Crimping nut 70 N-m with a special wrench.

5)Wind the rope on the end of the Spline shaft as shown. Fix the Spring balance on the other end of the rope & measure the pinion bearing preload.

6)Pinion preload should be within 3.0 – 8.0 kg.

*If the Preload is more – add some more shims. *If the Preload is less – remove some shims.

CONE CENTER DISTANCE

1)Measure the gap between ‘Circlip’ & ‘Spacer’ with a FEELER gauge.

2)The gap should be 0.10 mm. Add SHIM to fill the excess gap.

NOTE:-

Ensure free movement of bearing rollers after assembly. Assembly should be free from dust and foreign particles. No Grease should be applied during assembly
