How to Install a Bobcat 4G32 Timing Belt

by Brenda Priddy

A Bobcat 4G32 is a skid steer loader tractor used in outdoor construction, warehouses and other industries. The steer loader has a variety of uses, including moving materials from one place to another, digging holes, shoveling snow and placing objects or boxes onto pallets or shelves. The Bobcat 4G32 has a 4-cylinder gas engine that has a timing belt just like any other engine. Replacing the timing belt will help the engine work again and prevent future belt issues. The process of replacing the belt is the same as for any other engine.


Open the back of the Bobcat 4G32 to expose the engine. Unscrew any screws holding the back plate in place with a screwdriver, and set the back plate and screws aside in a safe location.


Jack up the tractor to expose the bottom of the engine for easy access.


Locate the crankshaft of the engine. It should be located near the camshaft and flywheel. Set the timing marks on the flywheel and cam so that the number one cylinder faces the top dead center (TDC) mark. You should be able to change this by flipping a small switch with your fingers or a screwdriver.


Locate the timing belt cover. It should be near the crankshaft. Unscrew the screws holding the cover in place and set them and the cover aside.


Locate the tensioner pulley adjustment bolt holding the belt tight along the crankshaft. Loosen this bolt with a wrench to loosen the timing belt.


Slip the timing belt off of the pulleys with your hands.


Place the new belt in place and fit it over the largest pulleys first, and over the smallest pulleys last. Make sure the timing marks are still in the TDC position.


Tighten the tensioner pulley adjustment bolt to secure the belt in place. Place a wrench over the bolt in the center of the largest pulley. Rotate the engine twice by tightening the bold. Align the marks into the TDC position again before testing the engine.
