	5.2.2 DriveMaster Super Kit		INDEX
	page 3 of 8 < PREVIOUS | NEXT >
Install a Super Kit if the bearings are running rough or if the DriveMaster fan drive needs to be completely rebuilt due to excessive wear. The Super Kit consists of the parts listed and described below:			Learning Objectives: • Describe when a Super Kit would be used.
	Fan Mounting Disc (#1): The fan mounting disc is the part that the fan is bolted on to. It is also the part that contacts the friction liner when the fan drive is engaged. The fan mounting disc is screwed onto the jack bolt. Different DriveMasters have different stud lengths. Check this when making repairs. Button Head Screws (#2) Friction Liner (#3): Attached to the sheave on top of the spring housing / piston assembly. Cage Nut (#4) Spring Housing / Piston Assembly (#5): The internal mechanism that engages and disengages the DriveMaster fan drive when air pressure is either removed or applied. Air Chamber Seal (#6) Retaining Rings (#7, #12) O-Ring (#8) Face Seal (#10) Bearing Nut (#11): Used to hold the sheave onto the journal bracket shaft. Air Cartridge (#13) Sheave Bearings (#14): Use a bearing press to remove old bearings and install new bearings into the center of the sheave. The bearings are prelubricated and sealed. They also have markings that need to be aligned for proper installation. (If there are spacers in between the old bearings that were removed, reuse those spacers by positioning them between the new bearings before installation. DO NOT remove the seals and attempt to lubricate the old or new bearings.) Some DriveMasters use one double row bearing instead of the two single row bearings. Check to make sure you have the right kit. T55 Torx Plus Bit (not pictured) O-Ring Lubricant (not pictured)
