LUBRICATION SYSTEM | GENERAL FOR 1500CC ENGINES REFER TO PART B OF THIS CHAPTER

1. A forced feed lubrication system is incorporated in these engines which circulates oil round the engine from a supply in the sump below the engine block. Engine oil level is indicated on a dipstick located on the right-hand side of the engine. It is marked to indicate the optimum level, which is the upper of the two marks; the lower mark indicates the minimum level to which the oil should be allowed to drop. Oil is replenished via the filler cap on the top of the rocker cover.
2. The oil pump is mounted at the end of the crankcase and is driven by the camshaft. Three different types of oil pump have been fitted at different times. These are the Burman rotary vane type, or the Hobourn Eaton, or the Concentric (Engineering) Ltd. concentric rotor type. All are of the non-draining variety to allow rapid pressure build-up when starting from cold.
3. Oil is drawn from the sump through a gauze screen strainer and is sucked up the pick-up pipe into the oil pump. From the pump it is forced under pressure along a gallery on the right-hand side of the engine, and through drillings to the big-end, main and camshaft bearings. A small hole in each connecting rod allows a jet of oil to lubricate the cylinder wall with each revolution.
4. From the camshaft front bearing, oil is fed through drilled passages in the cylinder block and head to the front rocker pedestal where it enters the hollow rocker shaft. Holes drilled in the shaft allow for the lubrication of the rocker arms, and the valve stems and pushrod ends. This oil is at a reduced pressure to the oil delivered to the crankshaft bearings. Oil from the front camshaft bearing also lubricates the timing gears and the timing chain. Oil returns to the sump by various passages, the tappets being lubricated by oil returning via the pushrod drillings in the block.
5. On all models a full-flow oil filter is fitted, and all oil passes through this filter before it reaches the main oil gallery. The oil is passed directly from the oil pump across the block to an external pipe on the right-hand side of the engine which feeds into the filter head.

ELECTRICAL SYSTEM

STARTER MOTOR | REMOVAL AND INSTALLATION

1. Disconnect the battery ground lead and apply the handbrake.
2. Depending on your model, some equipment may need removing to improve access to the starter motor. For example, you may need to remove the air vent hose, and also the fuel pump if you have an engine driven pump (see Chapter 3 for details).
3. When you can get to the starter, undo and remove the nut and washer securing the electrical cable to the starter motor and move the cable out of the way.
4. Remove the two nuts and washers retaining the starter motor to the engine and withdraw the motor from the bolts (see photo). Retrieve the shim and adaptor noting the sequence in which they are fitted.
5. Installing a starter motor is the reverse of the removal procedure, but make sure that, when the motor is being fitted, the terminal for the electrical cable is uppermost. Tighten the retaining nuts to their specified torque and finally, refit any components you had to remove.
