Fan Freewheeler

1. Before starting installation, lay out and identify all com-
ponents, including fasteners, to determine if anything is
missing.

2. Remove existing fan blade and spacer and determine
pump shaft diameter. The “FREEWHEELER” is designed to fi t
a ¾

" diameter water pump shaft. If shaft diameter is 5/8", use

5/8" to ¾

" bushing ALL99026 (not supplied).

3. Push water pump pulley(s) squarely against the fl ange on the pump shaft and measure distance the water
pump shaft protrudes through pulley. The maximum acceptable distance here is 5/16". If shaft length exceeds
this dimension, carefully grind the shaft protrusion.

4. Install the “FREEWHEELER” drive mandrel and pulley(s) and bolt to the water pump with the 5/16"-24 x 1"
socket head capscrews. Make sure that the capscrews fully engage the water pump fl ange by looking at the
backside of the pulley. (Maximum pulley thickness with these bolts is ¼

". If setup is thicker, proportionately

longer bolts will have to be used.) Once proper bolt length has been determined, remove bolts and apply blue
thread locker to the threads, re-install and torque to 19 ft. lbs.

5. Slide the “FREEWHEELER” housing assembly onto the mandrel. Apply thread locker to the ¼

"-20 x ½

" bolt,

install it and the 7/8" diameter fl at washer to retain the housing on the mandrel. Torque the bolt to 4 ft. lbs., or
49 in/ lbs.

6. Apply anti-seize to the 5/16"-18 x 1" hex bolts and then install the cap and fan blade, using the lock washers
and fl at washers. Torque the bolts to 13 ft. lbs.

7. The “FREEWHEELER” is now ready to use. The knurled head lockbolt can be inserted and secured with the
nut and washer when fan is to be used. Torque the locknut to 12 ft. lbs. When fan is not needed, remove the
lockbolt. (A plastic hammer may be needed to gently tap the lockbolt for removal or installation.) Use WD-40
or equivalent occasionally to ease installation.
