This is a factory made replacement brake hub/drum that fits 2 cycle gas E-Z-GO Golf Carts made from 1982 to 1994 and electric E-Z-GO Golf Carts and Utility Vehicles made from 1982 to Present. This brake drum has a 3/4" center hole with a 24 tooth 'star' spline. The drum is held in place by a castellated nut (5/8" x 18tpi) and a thick (.118") flat washer. This hub drum has the smaller center hole as shown on the right in the picture.
E-Z-GO Part # 19186G1
This hub/drum also will fit the E-Z-GO electric 4 seater personnel carriers (Liberty, PCX4, 4 Caddy & TXT 2+2) and utility trucks (800 [both the earlier 2-cycle gas 800 and the later Industrial & Turf 800 electric] and the WorkHorse & MPT models 1000E). This also includes the Cushman Commander 2100 electric truck, the Jacobson 1110 electric Hauler. It also fits on many other golf car brands that have the same Dana H-12 electric differential such as Columbia ParCar, Hyundai (gas & electric) and Melex but not Yamaha.
In the early 80's E-Z-GO used an axle hub with a separate brake drum that slides over the brake shoes & hub. This one piece hub/drum is suitable to replace the early hub & drum, if they have the star spline described above. Some of the very early 80s cars had a separate hub that employed a straight key rather than the star spline. This hub/drum will NOT work with keyed axle/hub interface.
Note 1: A thin shim (.032") is required between the drum and the axle bearing. The thin shim & thick outer flat washer are essential to the proper tightening of the hub/drum to the axle. The shim slides onto the axle & fits between the inner hub/drum surface & the axle bearing. The thick washer goes against the outer hub/drum followed by the castellated retainer nut. Tighten the nut to 80 foot pounds (140 ft lbs max.), using a torque wrench, and then tighten a little more to the next position so as to insert a cotter pin.
Note 2: If the nut works loose the entire hub/drum will start to rock on the splines each time you start & stop the car. Eventually the splines in the hub/drum will strip out and the car will not move, even though the engine (or motor) seems to work fine. If this happens to you look at the hub/drum retainer nut as someone starts the car. If the nut spins and the car does not move, then the drum has spun out and you will need to replace it. Usually the axle is OK but be sure to clean the axle splines before installing the new drum.
Note 3: Clean off any dirt or rust and check for grooves or excessive wear, especially at the edges. Scruff up the inner drum surface and the brake shoe material with some course sandpaper to deglaze the surfaces.
If you can't get the rust off, or if the drums are badly worn, replace them. The drum should not be resurfaced on a brake lathe.
