MAINTENANCE
Read all of SAFETY and this section before attempting any procedure. Pay particular attention to Notices, Cautions, Warnings and Dangers.
Tighten a new starter/generator belt to 110 - 130 lbs. (50 - 59 kg) ten-
sion when a gauge is applied half way between the two pulleys.
A new belt may be checked manually. A maximum deflection of 3/8"
(10 mm) is acceptable. Tighten an existing belt to 75 - 80 lbs. (34 -
36 kg) tension using the same technique and inspect for cracking or
wear. A maximum deflection of 1/2" (13 mm) is acceptable.
Adjusting the Belt
Loosen the starter/generator pivot bolt.
While holding the lower adjusting nut with a wrench, loosen the upper
jam nut with another wrench. Move the lower nut up or down the
adjustment bolt until proper belt tension is achieved. Hold the lower
nut in place and tighten the upper jam nut against it.
Tighten the starter/generator pivot bolt.
BATTERY CLEANING
To reduce the possibility of damage to vehicle or floor, neutralize acid before rinsing battery.
To reduce the possibility of damage to electrical components while cleaning, do not use a pressure washer.
Cleaning should take place per the PERIODIC SERVICE SCHEDULE.
When cleaning the outside of the battery and terminals, first spray with a solution of sodium bicarbonate (baking soda)
and water to neutralize any acid deposits before rinsing with clear water.
Use of a water hose without first neutralizing any acid, will move acid from the top of the battery to another area of the
vehicle or storage facility where it will attack the metal structure or the concrete/asphalt floor. Additionally, a residue will
be left on the battery which is conductive and will contribute to the discharge of the battery.
To reduce the possibility of a battery explosion that could result in severe injury or death, do not
use metallic spray wand to clean battery and keep all smoking materials, open flame or sparks
en-50
away from the battery.
