The coolant pump and alternator are driven by the belt drive,
as also is the A/C compressor.
(The fan is mounted on a special bracket and is driven by
the hydraulic system. See in chapter 5 Hydraulic system)
The drive belt is a “Multigroove V-belt”, i.e. the belt has numer-
ous V-shaped grooves on the drive side. The pulleys are of
corresponding design and the belt therefore has an extremely
large contact surface for its width. A large contact surface re-
duces the risk of belt slippage.
Included in the belt circuit are also jockey pulleys, the purpose
of which is to give the belt a good arc of contact round the pul-
leys.
An automatic belt tensioner is used to obtain the correct belt
tension.
