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 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 (engine numbers listed below) 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.
Series 2 Range Rover Main Bearing Sets
Note: The latest bearing sets feature thrust plates only on the upper half of centre bearing.
'Stroker Kits'
Includes new 86mm stroke camshaft, con rods, pistons/rings & bearings. 4.3 kit fits to 3.5 litre engine (20 thou rebore required) for 4.3 litres. 4.8 kit fits 3.9 litre engine (94mm bore) for 4.8 litres. Not suitable for 4.0 or 4.6 litre blocks.
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 instruction 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.
