Fan Hub Installation
The following instructions detail the process for installing a Marley
®
HP7000 fan on a Marley Geareducer
shaft utilizing a bolted fan hub retention plate or a straight fan shaft
using a split taper bushing. Installation on other gear reduction
units may be different. Contact your Marley sales representative
for supplemental instructions if required.
with a tapered fan (output)
Note
If the fan installation is for a Marley 36, 38, 3600, or 4000 model
Geareducer, or uses a U1 split taper bushing on a straight (output) shaft, refer to the applicable instructions below.
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 7″ (180mm) 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
certain 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–Install the retention plate and hardware. Torque bolts to 70 ft·lb
(95 N·m).
ƒ
36 and 38 Geareducer
36 and 38 Series Geareducers use a tapered fan shaft key.
Correct key installation is imperative for proper and safe operation. The following instructions detail installation for these
applications.
1–Remove the retention plate and hardware from the top of the
Geareducer. Thoroughly clean the fan shaft, fan shaft key, and the
hub center bore to remove any debris and/or protective coatings.
After cleaning, apply a coat of anti-seize compound to the top 7″
(180mm) of the fan shaft.
2–Install the 36 and 38 Series Geareducer fan shaft key in the fan
shaft keyway as shown in Figure 2. The key is a tight fit across the
width and must never be altered.

Fan Hub Installation
3–Raise the hub assembly above the fan shaft for installation. Slowly
lower the assembly onto the shaft with the keyways aligned. Make
certain the key does not slide down during installation. Stake the
key in the keyway with a center punch if necessary.
Figure 3
36 and 38 Geareducer
After the hub assembly is installed the bottom end of the key must
extend through the bottom of the center hub, and the top end of
the key must extend 5/8″ (16mm) minimum above the top of the fan
shaft. Do not force the key down once these criteria are met.
4–Figure 3 illustrates proper retention plate and hardware installation. The retention plate is designed to allow clearance for the fan
shaft key, and when properly installed will not extend over or interfere with the key in any way. Torque the retention bolts to 70 ft·lb
ƒ
(95 N·m) then turn up the locking strap corners to prevent the bolts
from loosening.
