Assemble the Bearing 30X62X16 (11) in Spindle with suitable dolly

Fitment of collar (14) to Spindle Groove (3)

Fitment of O-Ring (12) to Hub Housing

Ensure free rotation of bearing rollers after assembly

Assembly should be free from dust and foreign particles

Apply grease during assembly of oil seal only

Hub End Assembly Critical Settings

For cassette oil seal, maximum internal float recommended is 0.30 mm. Hence SHIM (7) selection is required to control it within 0.20 mm (if more, the lip of the oil seal will invert). Calculation must be done when Spindle or hub housing is replaced. It should also be done when early hour oil seal leakage is observed.

For Example- reading = 0.32 mm

Recommended maximum float = 0.20 mm

SHIM = 0.32 – 0.20 = 0.12 mm Spindle Play should be max. 0.20mm

NOTE:-

HUB END -ASSEMBLY PROCESS

HUB END ASSEMBLY CRITICAL SETTINGS

On hub housing, measure the GAP from bearing top to hub housing flange using tool “AGFAYNMG 004”

For ExampleMaster height = 35.00 mm

Measured reading = - 0.204 mm

GAP = 35.000 – 0.204 = 34.796 mm
