Removing and Replacing Belts
Remove belt guard. Loosen starter-generator unit
mounting bolts and push the unit toward the engine as
far as it will go. The belt (s) can then be removed.
(Note: Starter-generator units on some models are
equipped with two belts. On these units, both belts
should be replaced even though only one belt appears to
be worn. Use only matched sets of belts.) Do not force
belts onto pulleys. There is sufficient adjustment to allow
them to be slipped in place. After belt has been installed
apply a 30 lb. (13.6 kg) force to the upper pulley and
Tighten mounting bolts securely and replace belt guard.
NOTE: Belts are of special high strength design. See
Figs. 134 and 135 on page 43. Use only genuine factory
replacements obtainable at authorized Briggs & Stratton
Emergency Winter Operation
If run-down batteries are repeatedly experienced due to
short or infrequent operation at low temperatures, it is
advisable to temporarily increase the generator charge
A simple method of increasing the charge rate is to
disconnect the lead to the regulator BAT terminal and
reconnect this lead to the regular (L) terminal. This
bypasses the current-voltage feature of the regulator
automatically increasing the amount of charge to the
battery. See Fig. 132.
: Operate the regulator with these connected during cold
weather when operating periods are short or infrequent.
Re-establish the original lead connections as soon as
mild weather returns or operating time becomes normal:
otherwise the battery will be damaged by over charging.
A 12 volt battery of 50 ampere hour capacity is
recommended. CAUTION: Battery must have negative
(-) terminal grounded to engine or machine frame.
Maintenance of Battery and Cables (See Fig. 131 for
Check electrolyte level every 100 hours. Maintain level
with distilled or demineralized water. Avoid overfilling.
Keep top of battery clean by periodically washing with a
brush dipped in ammonia or bicarbonate of soda solution
followed by flushing with clean water. Keep battery hold
down clamps tight to prevent vibration of battery, but do
not overtighten as this may warp case.
Battery cable clamps must be kept tight on terminals to
provide a good contact. If corrosion occurs at terminals,
disconnect cables and clean clamps and terminals
separately. Coat clamps with petroleum jelly and re-
