PULLEY DISTANCE AND ALIGNMENT 0
GENERAL
The pulley distance we will refer to in this section,
is the space separating the drive and driven pulley
outside diameters (Z measurement).
This basic distance is provided as an assembly
guide and indicates the dimensions between which
satisfactory belt deflection will be obtained.
Both pulley distance adjustment and pulley align-
ment must be carried out to ensure the highest
efficiency of the transmission system. Further-
more, optimum drive belt operation and minimal
wear will be obtained only with proper pulley align-
ment.
CAUTION: Before checking pulley adjustment,
the rear suspension must be mounted on the
vehicle and track tension/alignment must be
done. Always check pulley adjustment after
suspension is adjusted.
All pulley alignment specifications refer to:
X = Distance between straight bar and drive pul-
ley fixed half edge, measured between pul-
leys .
Y = Distance between straight bar and drive pul-
ley fixed half edge, measured at the end of
straight bar .
Z = Distance between outside diameter of pul-
leys.
GENERAL PROCEDURE
Remove guard.
Tundra
Use driven pulley opening tool (P/N 529 034 200).
Skandic LT/LT E
Use driven pulley opening tool (P/N 529 035 501).
All Models
Remove drive belt.
Insert a straight bar 9.5 mm (.375 in) square, 48 cm
(19 in) long or the proper alignment bar into the
opened driven pulley.
Measuring Procedure
Using Straight Bar
Always measure distances X and Y from the far-
ther straight bar side (including its thickness to the
fixed half edge).
1. Straight bar
2. Front of vehicle
The distance Y must exceed distance X to com-
pensate for the twist due to the engine torque.

WARNING
Failure to correctly perform pulley alignment
may cause the vehicle to creep forward at idle.
