BobCat 753 – FLYWHEEL AND HOUSING – Ring Gear Removal And Installation

NOTE: Photo’s may be different but the procedure is the same for all models.

Remove the flywheel. (See Flywheel Removal And Installation on Page 70-90-1.)


The ring gear (Item 1) [Figure 70-90-4] on the flywheel is an interference fit. Heat the ring gear enough to expand the gear. Hit the ring gear evenly around the gear to remove it from the flywheel.

Clean the outer surface of the flywheel thoroughly so the new ring gear will fit smoothly onto the flywheel.

Clean the new ring gear and heat it to a temperature of 450°-500° F. (232°-260°C.)

Fit the ring gear on the flywheel and be sure the gear is seated correctly.
