CASTOR WHEEL AND FORK
DISMANTLING
STEP 1
Remove castor socket cap with flat bladed screw driver, hold the lower fork stem nut secure
with 19mm spanner and remove the upper fork stem nut.
STEP 2
Gently tap the threaded end to the fork stem with a mallet taking care not to damage the
threads. Remove the castor fork assemblies
STEP 3
Lever out the top fork bearings carefully, using the fork stem as a lever. Take care not to
damage the threads.
STEP 4
Remove the castor fork bearings using a drift and a mallet, tapping gently to avoid damaging
the castor socket and bearing.
STEP 5
To remove the castor wheels undo the axle nut with a 13mm spanner using a second
spanner at the other end of the axle to lock against rotation. Remove the axle bolt and
remove the wheel from the fork.
STEP 6
Remove the bearings by hand.
To reassemble reverse step 6 & 7, but adjust tightness of nut until the wheel runs freely to a
gradual halt.
a) If the wheel stops abruptly, loosen the castor axle nut.
b) If the wheel wobbles (sideplay), tighten the castor axle nut enough to allow free spinning
without sideplay.
TO RE-ASSEMBLE
STEP 1
Insert the fork stem bearings using a mallet and drift across the bearing to prevent damage.
STEP 2
Start at the bottom and place the threaded end of the fork stem through both bearings and in
the castor fork socket.
