How to use this chapter
This part of chapter 2 describes the repair work. which can be carried out without removing the engine from the vehicle. If the engine is removed from the vehicle and will be disassembled as described in parts D, all preliminary steps for disassembling the engine can be skipped. Note that despite the fact that it is physically possible to carry out a bulkhead of such units as a connecting rod and piston group without removing the engine from the car, these operations are not carried out separately. Usually some additional operations must be carried out (not counting the cleaning of parts and oil channels). For this reason, such operations are classified as main actions and are described in parts D of this chapter.
IN parts D describes the removal of the power unit from the vehicle and repair operations that can then be carried out.
Engine Description
The engine is a six-cylinder, in-line, with one camshaft installed in line ("North South") with a transmission located behind the car.
The crankshaft is mounted in a cast-iron cylinder block on seven main bearings. Axial movement is controlled by thrust washers mounted on each side of the 5th main bearing.
The connecting rods are attached to the crankshaft with horizontally cut connecting rod bearings, and to the pistons with floating piston pins secured with circlips. Three piston rings are installed on the pistons: two compression and one oil scraper.
The camshaft is driven by the camshaft sprocket from a single row chain.
The camshaft is held in seven bearings on an aluminum alloy cylinder head and actuates the valves via cam levers.
Chain driven oil pump from the front of the crankshaft.
