Cush Drive Rebuild

	Cush Drive Rebuild
	Tools Used: Drill Press Safety Glasses Ball Peen Hammer Rubber Hammer Flat Head Screwdriver Pick tool Small Punch Center Punch Pliers Circlip Pliers Channel Locks Vice
	To test the Cush Drive shake it If it makes noise the Springs inside are broken
	This step will happen when you take the Cush Drive out of the motor, this is for demonstration purposes only Push the threaded side of the Cush Drive Spindle
	With you other hand catch the Roller Bearings Inspect the roller bearings. There should be 21 to 24 depending on your model.
	SET the Cush on the vice DO NOT tighten it
	Pull the Circlip that retains the bearing
	Flip it over
	With a Rubber Hammer gently tap the Cush Drive Spindle Make sure the vice is open larger than the bearing on the other side This will push the bearing out
	The Bearing and Cush Drive Spindle will be stuck together you will need to separate them
	SET the Bearing and Spindle on the vice DON'T TIGHTEN
	Tap the Spindle and it will come free from the Bearing

	Inspect the Threads on the Cush Drive Spindle REPLACE if they are damaged
	Now you are going to drill out the Rivets
	With a Center Punch tap each rivet

	You are making a guide for the drill bit to go directly into the center of the rivet
	To start drill off the heads of the (6) rivets (7/32 drill bit)
	Lift off the metal plate
	Now you can see the springs
	Pull them out with your small screwdriver If they are broken they should just fall out
	Spin the Outer Gear Pull up on the Inner Gears

	Drill out the center of the rivets (5/32 drill bit)
	Be Careful it is very easy to break the bit Drill slowly The rivet is softer than the gear you will be able to hear when you are drilling into the gears if this happens stop and reposition it
	Pull the back plate off
	Clean EVERYHING BLOW off all the metal shavings


	Put the 2 gears back together BE CAREFUL you can put it together upside down
	THIS IS INCORRECT
	This is what it should look like (no lip)
	Install the NEW Springs out of your Rebuild Kit
	To install the NEW Springs compress them with the Cahnnel Locks and tap them with your hammer
	This is what it should look like when you are done
	Install the NEW Back Plate
	Install the NEW Rivets
	Install the NEW Top Plate
	To lock them in I like to use a vice to get them started
	Set the back part of the Rivet against the vice and peen the rivets with you ball peen hammer.
	It should look like this


	Install the Cush Drive Spindle with this side down (so the threads are sticking up)
	A little bit of Grease will help the bearing go in

	Use a Large socket to tap it in
	Install the Circlip

	Note: This step will actually happen when you install the drive into the motor but Ill show you now for demonstration purposes. Grease the bearing race
	Grease your finger
	Now the bearings will stick to your finger
	Place them into the race
	Tap the Cush Drive Spindle into the
