Fan Hub Installation

The U1 split taper bushing provided with the fan installation kit

U1 Split Taper Bushing will be either a Type 1 or a Type 2 bushing. A Type 1 bushing will use the fan shaft key provided with the Geareducer. A Type 2 bushing uses an integral key that is shared by the output shaft and the fan hub keyways. To distinguish which type of bushing is provided, refer to Figure 4.

1–Remove the fan shaft key from the top of the Geareducer shaft and discard if a Type 2 split taper bushing is being used. Thoroughly clean the fan shaft and fan hub center bore to remove any debris and/or protective coatings. After cleaning, apply a coat of anti-seize compound from the end of the fan shaft down to the length of the shaft keyway.

2–Remove the U1 split taper bushing from its packaging. Discard and replace the 5/8-11NC black steel cap screws provided within the bushing packaging with the 5/8-11NC stainless steel cap screws provided with the fan installation kit. Thoroughly clean the bushing center bore and outside taper (barrel) surface to remove any protec- tive coating. After cleaning, apply a thin coat of anti-seize compound to the outer taper surface of the bushing.

3–Aligning the outside taper (barrel) bushing key with the keyway of the hub bore, loosely start the Type 1 or Type 2 bushing into the bore of the hub. The three (3) threaded holes in the hub must be aligned with the non-threaded holes in the bushing flange—Note, the two (2) threaded holes in the bushing flange are used only for disassembly. Apply anti-seize compound to the threads of the 5/8-11NC stainless steel cap screws. Insert the cap screws through the non-threaded holes in the bushing flange and thread them by hand into the hub two or three turns only.

4–If a Type 1 split taper bushing is being used, prior to installing the bushing-hub assembly onto the fan shaft, fully seat the key in the fan shaft keyway. The key is a tight fit across the width and must never be altered.
