P a
rts List
All engine accessories are rigidly-mounted onto the cylinder block by means of accessory moun ting brackets on the left and
right-hand sides of the engine.
The left-hand bracket supports the air-cond itioning compressor and steering pump.
The right-hand bracket su pports the generator.
Dowels between the accessory mounting br ackets and the engine ensure that the accessory pulleys are accurately aligned
with the accessory drive belt.
A ccess
ory Drive on Supercharged Engines
The front
en
d accessory drive description and information for the
supercharged engine is identical to that given above. The
only difference is that the drive belt for the supercharger passes im mediately in front of the accessory drive belt. Therefore,
before any work can be done on the acce ssory drive belt and associated components, the supercharg er drive belt must first
be removed.
