Bell Housing Adaptor Kit – Holden V8 (Turbo Pattern) to Rover (4, 5-speed manual)

Bell Housing Adaptor kit to suit Holden V8 (Turbo Pattern) to Rover 4, 5-speed Manual

This kit is made to suit vehicles fitted with the Rover alloy V8 engine (3.5L, 3.9L, 4.0L) with a manual transmission.

The GM V8 engine kit consists of an adaptor plate that bolts to the rear of the engine. The standard Range Rover / Land Rover V8 bell housing then bolts to the rear of the adaptor plate. The transmission does not need repositioning for this conversion as the GM V8 engine has similar external dimensions as the Range Rover / Land Rover V8 engine.

Clutch

• A standard 10.5″ GM clutch kit can be used with the Range Rover / Land Rover 4-speed transmission as the clutch spline is the same (10 tooth)
• A 10.5″ GM clutch pressure plate and Rover 5-speed clutch plate can be used with the Range Rover / Land Rover 5-speed transmission.
• A Range Rover / Land Rover clutch kit can be used, but the GM flywheel will need to be re-drilled and tapped to accept it.

Clutch Kits

• Chev / Holden V8 Petrol 10.5″ 10T Spline – MCK117
• 10.5″ Chev petrol to Rover V8 23T spline – MCK410

Flywheel

The original GM flywheel and starter motor are used for the conversion. The bell housing will need to be modified to allow the starter motor nose to clear. If a hi-torque starter motor is used, the bell housing modification can be minimized.

When fitting Chevy petrol engines, the smaller 10.5″ 153 tooth flywheel must be used as the larger 11.0″ 168-tooth flywheel will not fit inside the original Range Rover / Land Rover bell housing.

Most Chevy petrol engines imported into Australia were originally fitted to automatic transmissions. Marks 4WD Adaptors manufacture flywheels to suit these engines.

A Range Rover / Land Rover clutch kit can be used; however, the GM flywheel will need to be re-drilled and tapped to accept it.
