How do you fit fan belt on Massey Ferguson 1135?

To fit the fan belt on a Massey Ferguson 1135, first, ensure the engine is off and cool. Loosen the tensioner pulley to relieve tension on the old belt, then remove it. Route the new belt according to the engine's belt diagram, ensuring it fits snugly around the pulleys. Finally, adjust the tensioner to apply proper tension to the new belt, and double-check the alignment before starting the engine.
