Lesson 3/Learning Event 2
Maintenance of the Drive Belts.
To adjust the drive belts, perform the
following steps.
Step 1. Remove the tensiometer from the toolbox and check to see that it is
clean and serviceable.
Step 2. Set one O-ring at the 3/8-inch mark, and the other O-ring at the 0-
pound mark against the sleeve. Put the small end of the tensiometer against
one of the four drive belts, halfway between the engine and pump pulleys
(figure 10). Press down on the tensiometer until the O-ring at the 3/8-inch
mark touches the belt next to it.
Remove the tensiometer and read the
position of the second O-ring which was moved down the scale by the sleeve.
The O-ring should be between the five to seven-pound mark for correct belt
tension.
