Flexible Coupling for Engine/Transmission
A flexible coupling is mounted between the engine and transmission. The half with the 1” bore
mounts to the engine, the half with the ¾” bore mounts to the transmission. A flexible coupling
element is between the two coupling halves.
1. Check the parallel alignment of the coupling in at least 4 places (every 90 degrees), top and
bottom and left and right sides. The sides of each coupling half must be within 0.015” in all axes.
If adjustment is required use the following procedure to align.
a) To begin this adjustment loosen engine and transmission mounting bolts but do not
remove.
b) First make the vertical adjustment to the coupling assembly by moving the transmis-
sion up or down on the transmission mount plate. Tighten transmission mounting bolts.
c) Using a straight edge make the horizontal adjustment to the coupling assembly by
moving the engine left or right on the engine mounting plate. Tighten engine bolts.
d) When alignment is correct and the engine and transmission mount bolts are secured,
recheck alignment with a straight edge.
e) When alignment is correct, both coupling halves and the flexible coupling element
should be centered between the engine and transmission shafts. The coupling assembly
should be pressed together as tightly as possible and the set screws tightened to the
torque specified. Use thread locking sealant. See notes below.
