Adjusting Drive Belt

1346 Views 3 Replies 2 Participants Last post by  gunbarrel
Craftsman GT model 917-273223 with a Kohler 24hp and Hydro-Gear transmission. Their is NO mower deck installed.

Is there an adjustment for the drive belt and if so how do I make the adjustment ? ( It is the long belt running from the front engine area to the rear of the unit).

All I have seen on the drive belt follows.

Park the tractor on level surface. Engage
parking brake. For ease of service there
is a belt installation guide decal on
bottom of left footrest.
• Remove mower (See "TO REMOVE
MOWER" in this section of this
• Engage parking brake (creates slack
in belt).
• Remove belt from clutching and fan
idler pulleys.
• Loosen belt keeper above transaxle
• Remove belt from transaxle pulley.
• Remove belt from engine pulley and
front V-idler pulley.
• Pull belt out of all belt keepers and
remove from tractor.
• Place V part of belt into grooves on
engine pulley and front V-idler, making
sure to route belt inside of all belt
• Route belt on right side, coming from
V-idler, towards back of tractor, above
midspan belt keeper and to top of
transaxle pulley.
• Route belt on left side, coming from
engine pulley, towards back of tractor
and through loop in midspan belt
• Place V part of belt into grooves on
transaxle and fan idler pulleys, making
sure to route belt inside of all belt

If you don't have a manual you can find a copy here.

Be sure to read the troubleshooting section about "Loss of Drive".

Thanks for the information, looks like there is no adjustment for the belt. Found the installation diagram under the left footrest as you suggested.
