Crankshaft


All parts listed are suitable for Saloon/Sports and 4x4 applications unless otherwise stated.
Note: Around mid 1994, Land Rover introduced a crankshaft-driven oil pump - built into the timing cover - for certain 3.9 litre and larger engines. These engines required a crankshaft with a longer 'nose' than previous engines.
For this reason, crankshafts are available with two different nose lengths, as follows:-
All 3.5 litre engines, plus factory 3.9 & 4.2 litre engines up to around mid 1994 (exact engine numbers are listed below), are fitted with short-nose (70.6mm) cranks. These engines have camshaft-driven oil pumps and separate drivebelts for ancillary components.
3.9 & 4.2 litre engines from around mid 1994 onwards are fitted with long nose (90.3mm) cranks. These engines have crank-driven oil pumps and a single, serpentine drivebelt for the ancillary components.
Please check your engine number before ordering.
The exchange unit must be a similar type, otherwise a surcharge will apply.

Stroker Kits
These kits enable you to enlarge the cubic capacity of your existing engine by increasing the stroke, hence the name 'stroker'. The kits comprise a brand new, high quality crankshaft, conrods and pistons (with bearings and piston rings supplied). The stroke is increased from the standard 3.5/3.9 engine’s 71.1mm to a massive 86mm, (longer than the standard 4.6 litre stroke of 82mm) giving a capacity of 4.3 litres on a 3.5 engine and 4.8 litres on a 3.9 engine. Both engines require a 20 thou rebore before fitting. Finally, a small amount of grinding is required to the bottom of two cylinder liners (full instructions supplied) to allow clearance for crank rotation. The result of the extra stroke is a huge increase in torque, even on an otherwise standard engine. Alternatively, you have the basis of a high performance engine, to which you can add our fully modified, big valve cylinder heads, uprated camshaft and sports exhaust system.
