Rochdale Owners Club: Rear suspension Phase 2

 

 

 

Rochdale Olympic phase 2, rear suspension.

 

 

 

The Phase 2 rear is based on either the small Ford axle or the BMC axle from either the Riley 1.5/Wolseley 1500 or the Morris Minor. RMP modified these axles to accept their own fabricated rear radius arms, torque reaction arm and transverse panhard rod in place of the semi elliptical leaf springs of the donor vehicle. They use spring/damper assemblies similar to the Phase 1, however these are mounted on the fabricated radius arms rather than acting directly on the rear axle. The top mounting of these assemblies is also lower and somewhat easier to access, being located inside the car itself.

Rear axle removal

Jack up the rear of the car and support on suitable axle stands or similar. these should be placed under the body of the car (with a 12" x 12" thick wooden plate to spread the loading) at the point where the inner wheel arch vertical moulding, and the floor intersect. Remove the rear wheels and place under the car or in a suitable place for safe storage.

 

Undo and remove the flexible brake hose between the axle three way hydraulic pipe connector and the body of the car.

 

Undo and remove the handbrake cable from the axle at the handbrake lever, for the BMC axle item 47 in the exploded view above, for the Ford axle item **** in 2nd the exploded view above.

 

Undo the 4 5/16"UNF nuts and bolts which hold the rear hardy Spicer joint for the prop shaft and remove the prop shaft completely from the car by sliding the splined front end of the shaft first inwards to clear the differential then pull it off the gearbox to remove the prop shaft.

 

Support the axle in its current position using suitable axle stands, be careful not to compress the spring/damper assemblies at this point.

Undo the rear radius arm nuts/bolts which hold the radius arms onto the axle and drift out the bolts to free the radius arms from the axle.

 

Undo and remove the torque reaction arm from the bracket on the top of the axle, located on the drivers side.

 

Note

The rear axle can now be removed and lowered to the floor, due to the weight of the axle it is highly recommended that it be done by two people working one on either side of the car.
