CooLift
®
1)
Place the CooLift on a level flooring surface with the holding brake engaged. Raise deck completely.
Turn
off main power switch.
Disconnect the batteries.
2) Disconnect the motor from the propulsion controller.
3) Remove the deck and the rear bottom pan.
4) Loosen the jam nut on the motor adjustment plate on both sides of the unit. Loosen the 3” long outer
adjustment screw so that the motor can slide forward.
5) Find the master link on the chain connecting the motor output sprocket to the clutch input sprocket. Use
pliers or a screwdriver to remove the master link. Remove and retain the chain and master link.
6) Remove the four 1” long hex head cap screws (B) from the motor adjustment plate on the LH side of the
unit (note - if you are only replacing the motor adjustment plate on this side, skip to Step 12).
7) Remove the two 2” long hex head cap screws (C) from the motor adjustment plate on the RH side of the
unit (note - if you are only replacing the motor adjustment plate on this side, skip to Step 13).
8) Lift the motor assembly and motor spacer plate out of the unit. Retain the motor spacer plate.
9) The new lift motor assembly will come with two screws in the side of the unit. Remove the two screws as
shown.
10) Place the spacer plate against the RH side of the motor so that the notch is toward the front of the CooLift
(as shown). Also ensure the plate is flush against the motor gearbox.
11) Place the motor in place in the CooLift. Wrap the chain around the motor output sprocket.
12) Apply blue thread locker to the four 1” long hex head cap screws (B) and insert through the adjustment
plate and into the CooLift onto the LH side rail; finger tighten only for now.
13) Apply blue thread locker to the two 2” long hex head cap screws (C). Insert into the motor adjustment
plate and into the CooLift onto the RH side rail; finger tighten only for now.
14) Wrap the chain around the clutch input sprocket. Install the master link.
15) Adjust the outer adjustment screws on the motor adjustment plates until the chain has 1/4” play between
the two sprockets. Make sure that the motor adjustment plates are the same distance apart from the block
on both sides of the frame.
NOTE 1: Uneven tensioning of the chain between the clutch and motor will cause alignment issues.
Misalignment will cause: extra noise, chain wear, uneven sprocket wear, potential for the chain to come off
sprocket, and potential failure of the chain and/or sprocket.
NOTE 2: Over-tensioning of the chain (even if tensioned evenly on both sides) can also cause issues.
Over-tensioning may cause deflection of the motor output shaft resulting in miss alignment of the chain
(see NOTE 1) and may result in shorter bearing life in the propulsion motor. Over tensioning will cause
the chain to stretch faster, leading to shorter chain and/or sprocket life.
16) Tighten the jam nut on the motor adjustment plate.
17) Fully tighten the hex head cap screws in all adjustment plates.
18) Replace the deck and bottom pan (use blue thread locker on the screws for bottom pan). Plug the motor
into the controller. Reconnect the batteries.
19) Turn on the unit. Carefully test propulsion to make sure it drives in the intended direction.
