Belt Replacement

Drive Belt

NOTE: To aid in reassembly, note the orientation of the drive belt

on the two idler pulleys and the engine flywheel pulley prior to

performing the following steps. Refer to Fig. 7-1.

The edger drive belt is subject to wear and should be replaced if

any signs of cracking, shredding or rotting are present. To replace

the belt, proceed as follows:

Working in front of the edger, loosen the flange lock nut

on top of frame, allowing the idler pulley assembly to pivot

slightly out from the frame. See Fig. 7-1.
With your other hand, carefully reach under the rear of

the edger and remove the belt from around the engine

flywheel pulley. See Fig. 7-1.

Remove the spindle sheaves belt guard by removing the

two self-tapping screws which secure it to the blade plate

assembly. See Fig. 7-2.

Carefully remove the belt from off of the pulleys, again

making sure to note the orientation of the belt. Discard the

belt. See Fig. 7-2.
5. Working from the front of the edger, place the belt

onto the spindle sheaves, route it back onto the two idler

pulleys, and then place it onto the engine flywheel pulley.
NOTE: Make certain that the “V” side of the belt is seated

into the top pulley and the flat side of the belt is seated

into the bottom pulley. See Fig. 7-2.
Reinstall the spindle sheaves belt guard with the self

tapping screws removed earlier.
Make certain that the drive belt is on the engine flywheel

pulley and idler pulleys, and retighten the flange lock nut

on the top of the frame.
NOTE: Make certain that the drive belt is seated correctly

and that it is riding smoothly on the spindle sheaves and is

not pinched between them. Repeat the first three steps if

the belt is pinched.

WARNING!

Never operate the edger without the

spindle sheaves belt guard in place.
