Variable speed adjustment mtd rnach king

I have changed variable speed belts before, and always do it by replacing both belts, someone tell me how to adjust the rod that connects to the clutch brake and and speed contol lever, the vsp is in good shape and working properly, but the rear drive belt comes of when going to higher speeds. I have the proper belts, i just replaced identicle set a week ago, but didn't require adjustment and worked great, but this one had the rod from the clutch/ brake to the speed control apart. Tell me how to adjust this or how to cure throwing the rear belt. All the help will be appreciated. I can also make a customer happy with your help

Generally if the belt is coming off, there is something besides an adjustment wrong. Often the tensioner arm on these is bent a little and when it flexes, it allows the pulley to get out of alignment with the variator and transmission pulley, causing it to jump off.

There is also a threaded rod that goes from the brake clutch pedal to the speed control mechanism, this had been removed , I put it back on, so it also needs adjustment and there must be a procedure for this. on page 22 of the manual , It reads adjust the spped control as instructed in adjustment section, The manual is missing some pages and is missing the adjustment section, It is a 600 series,

I downloaded a manualfor the tractor. On page 17 . THERE IS A SECTION:SPEED CONTROL ADJUSTMENT: I WILL SHARE IT IN CASE SOMEONE ELSE HAS TO DO IT ALSO

IF THE FULL RANGE OF YOUR SPEED CONTROL CANNOT BE OBTAINED ON YOUR UNIT, ADJUST THE SPEED CONTROL AS FOLLOWS; .adjust the speed control lever by pushing the clutch-brake pedal forward against the stop rod on the running board, if you don't have a buddy to hold the pedal, a pair of vice grips work to hold the pedal there. Make the following adjustment. Place the speed controll lever in parking brake position. Remove the hairpin clip and flat washer, and adjust the ferrule on the rod so it is against the back of the slot. then lengthen rod one more turn Replace and secure flat washer and hair pin clip. Adjust speed control link as follows to obtain the correct neutral position. start the engine.
Place shif lever in Neutral position,
pLACE SPEED CONTROL LEVER IN HIGH SPEED POSITION
rELEASE THE CLUTH-BRAKE PEDAL COMPLETELY, THEN SLOWLY DEPRESS THE PEDAL ALL THE WAY(TO PARK POSITION)hOLD THE PEDAL IN THIS POSITION.
tURN OFF ENGINE>
RELEASE CLUTCH/BRAKE PEDAL.
pLACE SPEED CONTROL LEVER IN 2ND POSITION
rEMOVE THE COTTER PIN AND FLAT WASHER WHICH SECURES THE SPEED CONTROL LINK TO THE variable speed torque bracket assembly.
Push the clutch/brake pedal backward by hand as far as it will go using light pressure. Hold in this positionas you thread the speed control link in or out of the ferrule until it lines up with the pin on the variable speed torque bracket assembly.
Secure speed control link to variable speed torque bracket assembly with flat washer and cotter pin.

I did all of the above, It must have been an adjustment issue, I drove the tractor all over for over an hour, uphill down hill , around the block forward, around the block backwrds, and using all speeds. After doing the whole procedure, it has not thrown a belt, before I couldn't travel 20 feet before it threw the rear drive belt.
I know this was lengthy, and so was the process. I don't think any other shortcut would have worked. HOPE THIS HELPS SOMEONE WITH THE SAME REPAIR. (MAKE SURE TO ALWAYS USE OEM BELTS)

Glad that fixed it for you. I wonder what it was doing that allowed the belt to jump. Giving it too much slack I guess.
