Bolens 608, 609, 607 manual Lower Drive Belt, Front of Tractor

Lower Drive Belt

NOTE: Proper removal of the lower drive belt requires the removal of several tractor components. Read through the following procedure prior to attempting it to determine if you feel you could successfully complete it. If you don’t, see an authorized MTD service dealer to have the belt changed.

IMPORTANT: Note the routing of the lower drive belt around both the pulleys and the belt keepers BEFORE performing the following steps.

•Locate the variable-speed pulley by looking through the battery tray opening. See Figure 16.

•Remove the variable-speed pulley by loosening the hex bolt that secures it to the transmission. Use a second wrench to hold the hex nut on the bottom side of the pulley.

•Slide the belt off of the variable-speed pulley as you lift the pulley up and out through the battery tray opening.

•Remove the hex bolt from the center of the engine pulley. See Figure 17.

•Lower the engine pulley far enough to be able to remove the upper drive belt from around it.

IMPORTANT: When remounting the engine pulley, torque the center hex bolt to between 38 foot- pounds and 50 foot-pounds.

•Remove the drive belt by feeding it from both ends toward the front idler pulley on the double-idler bracket. See Figure 16.

•Reassemble by following the above steps in reverse order.

•Reroute the new belt around the pulleys, keeper pins and belt keepers EXACTLY as

the old one was routed. Refer to Figure 16. The drive pedal is properly adjusted when the hole found in the double-idler bracket has approximately 1-3/8" of travel with ten pounds of pressure applied to the drive pedal. See Figure 17.
