Toro 3650 squealing...??
Original Message Jan 11, 2009 3:22 pm |

I have a 4 year old Toro 3650 and it has been very good. However, of late it has started to squeal alot when it is under a strain from a bit of snow when before it used to go right through it. I presume this to be the drive belt? Does it need to be adjusted (if possible) or simply replaced? Is the drive belt replacement pretty easy if that is what you think it might be? Thanks in advance.

From the 3650 manual: Note: After extended use, the drive belt may wear and lose its proper belt tension. If the drive belt slips (continuously squeals) under a heavy load, increase the belt tension by inserting the spring end into the top hole of the control bar. The belt may slip (squeal) in wet conditions; to dry out the drive system, start the rotor and run it without a load for 30 seconds. Checking the Cable:
Important: Check the control cable for proper adjustment initially, after the first operating hour, and then annually thereafter.
1. Move the control bar back toward the handle to remove the slack in the cable.
2. Ensure that a 1/16 to 1/8 inch (2 to 3 mm) gap exists between the control bar and the handle
Note: To adjust the cable, refer to Adjusting the Cable below.
Important: The control cable must contain some slack when you disengage the control bar for the rotor blades to stop properly.
Adjusting the Cable
1. Unhook the end of the control cable spring from the control bar
2. Move the Z-fitting to a higher or lower hole in the adjuster link as needed to obtain the 1/16 to 1/8 inch (2 to 3 mm) gap between the control bar and the handle
Note: Moving the Z-fitting higher decreases the gap between the control bar and the handle; moving it lower increases the gap.
3. Replace the spring cover and hook the end of the control cable spring into the bottom hole of the control bar.
4. Check the adjustment; refer to Checking the Cable.

If by chance the belt does look worse for wear and you do need want to replace it, the procedure should be similar to what's shown below (from an older generic Toro single stage service manual) :

THank you both for your reply. I finally found the manual online and saw the pictures and instructions on how to change the belt. I did not see about changing the spring positioning. I appreciate your help. Jeff |
