Engine Service
CAUTION; Disconnect spark plug wire before working on machine.
For the engine, read “Honda Owner’s Manual”. Engine oil should be changed in conformity with “Honda Owner’s Manual”.
Keep the cylinder head clean so that it can cool the engine properly. Frequent oil changes will significantly prolong life of
engine. SAW 10W30 is recommended by Honda (see Honda Engines Owner’s manual). Unleaded gasoline is also
recommended to increase valve life.
If service or repair of engine is needed, contact an authorized Honda Centre,
GRIZZLY
equipment warranty does not cover the engine, which is covered by a separate warranty from Honda.
Lubrication
Lubrication recommendations are as follows: Roller bearings on wheels are pre-lubricated and require no greasing. Flange
bearings (item 17 on part list) that support planer disc are pre-lubricated and require greasing only about every 100 hours
operation. In extremely severe conditions greasing may be required more frequently. A high-quality lithium based multi-
purpose grease is proper lubricant. Use extreme care when pumping grease into bearing not to push too hard. Destruction of
bearing seal will otherwise result. Removal of belt guard is necessary for access t upper flange bearing. Treaded rod on
depth control requires a spray lubricant (such as WD40) to keep it turning freely.
Belt Adjustment
Belt adjustment may be necessary at times. To inspect belt remove dust plate on back of motor mount (see Fig. 8). Push
down on the belt with your thumb midway between pulley with about 20 lbs. pressure. When properly adjusted you should
get a deflection of nearly 3/4". To adjust belt, loosen 4 bolts on engine mount (item 101 on parts list). Then loosen locknut
on belt adjustment bolt, shown in Fig. 9. Turn bolt clockwise to tighten belt, counter clockwise to loosen. When desired
tension is set, re-tighten the locknut and also the four engine mount bolts. If belt replacement is necessary, remove belt cover
(item 4 on parts list) by removing two bolts. Replace belt cover after changing belt. Tighten bolts securely.
