Adjusting The Belt Tension - Eliet Major Anleitung

11.5.5 Adjusting the belt tension

Caution:
The engine should always be switched off and the spark plug cap should be
disconnected when adjusting the belt tension.
• To adjust the belt tension, remove the guard. To this end, remove the four M6
bolts (without nuts). The guard is also secured to the chassis by means of an M6
bolt equipped with a dome nut, and an M8 bolt at the front of the guard. Two ring
spanners should be used here (10 mm and 13 mm).
• To check the exact belt tension, a 7.5 kg weight
is suspended from the V-belt. If the belt sags by
1 cm, the belt tension is correct (see figure).
Adjust the belt tension by sliding the engine block forwards. To this end, four M8
•
bolts on the engine block should be unscrewed (2 x 13 mm ring spanners).
Slightly turn the M10 bolt at the front of the engine backwards after releasing the
lock nuts. The engine block can now be pushed forwards using the nut at the rear
of the engine.
• Prior to releasing the engine, use a felt tip to mark the chassis plate at the side of
the engine block. This will save time later when aligning the pulleys.
Tighten the (M10) bolt at the rear until the correct tension is obtained. The bolt is
•
secured with a lock nut.
Align the two pulleys by retightening the bolt at
•
front of the engine. The pulleys are correctly
aligned if they touch a straight piece of wood
held against them in four places (see figure).
CORRECT TENSION + CORRECT ALIGNMENT
After the correct tension and alignment have been obtained, the position of the
•
engine may be locked by firmly retightening the four engine (M8) bolts (using 2 x
13 mm ring spanners).
The guard should only be refitted in its original position once everything has been
•
carefully rechecked.
