V-Belts; Change The V-Belts; Checking Condition; Testing By Hand - Daewoo DE12T Manual

6.6. V-belts

(1) Change the V-belts if necessary
If in the case of a multiple belt drive, wear or differing tensions are found, always replace
the complete set of belts.

(2) Checking condition

Check V-belts for cracks, oil, overheating and wear.

(3) Testing by hand

•
V-belt
The tension is correct if the V-belts can
be pressed in by about the thickness of
the V-belt. ( no more midway between
the belt pulleys )
A more precise check of the V-belt
tension is possible only by using a V-
belt tension tester.
•
Poly belt
Poly belt will be properly tensioned if
the deflection force " F " is applied mid-
way between the belt's tangent points
with the pulley.
T = 0.015 x S ( about 1.5 mm per 100 mm )
T = 0.015 x *S (mm)
( T : Deflection, S : Span )
( D-d )
*S = C 2 -
C : Distance of pulleys (mm),
D : Large pulley diameter (mm),
d : Small pulley diameter (mm)
