Recommend using Hadley Wrench Kit T600200

The Retainer - Freehub Bearing/Seal can be removed using Park Tool FR-5 or FR-5.2 Cassette Lock Ring Tool

Also use light Teflon® fortified oil on freehub pawls.

FREEHUB ASSEMBLY –
1. REMOVE NEEDLE SLEEVE, NEEDLE BEARING AND SPACER FROM INSIDE
FREEHUB BODY. NEXT, REMOVE BEARING RETAINING RING FROM FREEHUB
BODY USING PARK TOOL FR-5 OR FR-5.2 CASSETTE LOCK RING TOOL.
2. PRESS OUT OLD FREEHUB BALL BEARING. REMOVE PAWLS AND SPRING AND
MAKE SURE THAT PAWL POCKETS AND INSIDE THE FREEHUB BODY HAVE
BEEN CLEANED. APPLY SOME HIGH PRESSURE LUBE INSIDE FREEHUB BODY
AND THEN PRESS NEW BALL BEARING ASSEMBLY BACK INTO FREEHUB BODY.
ONCE IT IS PRESSED IN, THREAD IN THE NEW BEARING RETAINING RING WITH CASSETTE LOCK RING TOOL .

3. REPLACE PAWLS IN PAWL POCKETS AND PUT SPRING BACK OVER THE PAWLS
BEING CAREFUL NOT TO OVERSTRETCH THE SPRING. OPENING OF SPRING
SHOULD ALIGN OVER THE PIN THAT IS PRESSED INTO THE FREEHUB BODY.
4. SET THE FREEHUB BODY DOWN WITH PAWL POCKETS FACING UP. DROP
SPACER BACK DOWN INTO OPENING ON TOP OF THE FREEHUB BODY. IT WILL
SIT ON TOP OF THE BALL BEARING THAT YOU JUST PRESSED IN. FOLLOW
THAT WITH THE NEEDLE BEARING AND NEEDLE SLEEVE WITH LIP OF NEEDLE
SLEEVE FACING UP(APPLY SOME OIL ON THE NEEDLE BEARING & NEEDLE
SLEEVE). NOTE: IF YOU HAVE A OLDER HUB IT MAY HAVE A LONGER NEEDLE SLEEVE AND YOU WILL NEED TO USE THE 1mm SPACER THAT IS INCLUDED IN THE KIT THAT WORKS WITH THE NEW SHORTER SLEEVE AND PLACE IT OVER THE AXLE IN THE GEAR AREA OF THE HUB SHELL (IN BETWEEN THE SLEEVE LIP AND THE MAIN HUB SHELL BEARING)
HUB ASSEMBLY –
1. REMOVE OLD SEAL FROM DISC SIDE END AND INSTALL NEW SEAL WITH
GROOVE SIDE FACING AWAY FROM THE HUB SHELL.
2. THREAD ON DISC SIDE END ONTO INTERNAL AXLE AND SLIDE BACK THROUGH
HUB SHELL. POUR OIL (TEFLON) INTO THE AREA WHERE THE PAWLS MEET
THE GEAR. USE ONLY OIL IN THIS AREA AS GREASE WILL PREVENT THE
PAWLS FROM PROPERLY ENGAGING.
3. TAKE FREEHUB ASSEMBLY JUST AS IT IS SITTING AND SLIDE IT BACK OVER
THE INTERNAL AXLE AND SPIN IT UNTIL IT DROPS DOWN INTO THE GEAR
AREA. BE CAREFUL NOT TO DAMAGE THE SEAL THAT IS INSTALLED IN HUB
SHELL.
4. THREAD DRIVE SIDE END BACK ON TO THE INTERNAL AXLE AND TIGHTEN
BOTH ENDS TIGHTLY. SPIN FREEHUB AND MAKE SURE THAT IT SPINS FREELY.
5. IF THERE APPEARS TO BE ANY SIDE TO SIDE PLAY IN THE HUB, THEN TIGHTEN
THE DISC SIDE LOCK RING SLIGHTLY, AGAIN BEING VERY CAREFUL AS TO NOT
OVER-TIGHTEN. THIS IS CRITICAL – AS OVER TIGHTENING THIS LOCK RING
WILL CAUSE DAMAGE TO THE HUB SHELL BEARINGS.
