Fan Hub Installation

The following instructions detail the process for installing a Marley HP7000 Fan on a Marley Geareducer® with a tapered fan (output) shaft and bolted fan hub retention. Installation on other gear reduc- tion units may be different. Contact your Marley sales representative for supplemental instructions if required.

1–Remove the retention plate and hardware from the top of the Geareducer shaft. Thoroughly clean the fan shaft, fan shaft key, and the fan hub center bore to remove any debris and/or protective coatings. After cleaning, apply a coat of anti-seize compound to the top 5″ (130mm) of the fan shaft.

2–Prior to hub installation, fully seat the key in the fan shaft keyway. The key is a tight fit across the width and must never be altered.

3–Raise the fan hub above the fan shaft for installation. Slowly lower the hub onto the shaft with the keyways properly aligned. Make cer- tain the key does not slide down during installation. Stake the key in the keyway with a center punch if necessary.

The fan shaft key should be approximately centered in the engaged portion of the hub when engaged on the shaft. Verify the center hub is fully seated by visual inspection.

4–The hub retention plate will sit on top of the spool. Discard the retention bolts that come with the Geareducer. New retention bolts are provided with the hub cover hardware kit. Torque bolts to 50 ft·lbƒ (68 N·m).
