How to: 751 Bobcat Timing Belt


Bobcats are multipurpose utility vehicles known for their ability to work heavy loads and turn on a dime. Though Bobcats are most often recognized for their frequent use as skid-steer and track loaders, they are also used as tractors and excavators, and can be fitted with a wide variety of attachments so that they can be used for other purposes. The 751 model boasts 40 horsepower, hydraulics, and hand and foot controls. Replacing a Bobcat's timing belt is very similar to replacing one in any other engine, and generally requires a working knowledge of automotive parts and function.

Things You'll Need

  • Car jack
  • Flashlight
  • Wrench
  • Replacement timing belt
  • Screwdriver
  • Jack up the Bobcat to allow for easier access through the bottom.

  • Remove the rear cover for the engine, and locate the large, cylindrical camshaft. It should be located near the flywheel.

  • Unscrew the plastic timing belt cover-- which is located beside the crankshaft -- and set it aside.

  • Using a spot or flashlight, check the status of the valves and pistons -- looking for breaks, dents, dings or cracks. If the valves or pistons are damaged, then the belt failed before it was replaced. The 751 Bobcat models were fitted with either Kubota or Peugeot engines, and only the Peugeot engine models had timing belts.

  • Loosen the timing belt. Find the tensioner pulley by following the belt over the camshaft; the pulley attaches the belt around the camshaft. Loosen the belt by loosening the pulley's bolt.

  • Slide the used belt carefully off its settings.

  • Place a new belt over the pulley and settings, taking care to keep the timing marks on center.

  • Tighten the tensioner pulley bolt to tighten the belt until it is strung taut over the pulleys.

  • Turn the engine twice by moving the wrench along the bolt of the largest pulley.

  • Double-check the alignment of the camshaft before replacing the timing belt cover.

  • Turn the engine on to check the assembly.

Tips & Warnings

  • Bobcat can often supply the Kubota converter kits at a substantially reduced price, compared to repairing damaged pins or pistons on the Peugeot engines.
