TO CHECK THE ENGINE OIL LEVEL
Be sure the correct engine oil level is maintained
by checking the oil level daily. Use the dipstick to
verify the correct oil level and add oil as indicated
on the dipstick. When changing the oil you must
first remove the drain plug which is located on the
rear of the engine. Refer to the Briggs & Stratton
Engine Owners’ Manual for more information on
recommended type and grade of oil to be used.
DRIVE SYSTEM SERVICE INSTRUCTIONS
TO ADJUST THE NEUTRAL SETTING
The only item that should have to be moved is the linkage rod itself. By adjusting the clevisis in or out, one
should be able to achieve neutral when you install the new belt or if the machine begins to creep.
TO REPLACE THE FORWARD DRIVE BELT
1. Remove the two (2) inspection plugs on the right hand side of the machine which allows access to the
bearing plate on the end of the differential.
2. Reach in through the inspection holes and remove the two (2) bolts that hold the differential bearing plate in.
Remove and retain hardware.
3. Loosen the chain idler pulley and move it to the top of the slot to relax all tension on the chain. Retighten
the idler.
4. Remove the drive wheel chain by walking it off the differential. With the idler out of the way, it should all you
plenty of clearance to come off the end of the differential.
5. Move the bearing plate in an upward position to give you clearance for installing the new belt.
6. Begin by working the forward drive belt around the bearing plate. Once this is around the bearing plate, the
reverse belt off the differential shieve and leave it lay off to the left hand side of the shieve.
7. Take the main forward belt and work it back around the forward idler underneath the main drive shieve and
around the rear of the forward and reverse idler pulley and up over the forward and reverse idler pulley.
8. When installing the forward drive belt, one side of the belt is printed and says “This Side Out”. On the
forward drive belt, you want to have that so you cannot read it when it is installed. It will be riding against
the shieve itself on the differential because the machine is driven off the backside of that belt.
9. Once that main forward drive belt is installed and routed correctly, reattach the reverse belt the same way it
was routed before.
10. At the front of the machine, refasten the bearing plate on the end of the differential to the frame.
11. Start you chain back around the differential and readjust the idler for the drive chain.
12. Any fine adjustments for neutral that need to be done should be done with the linkage rod only.
