How do I replace the rear wheel axle pins?

Tools/Supplies
(1) 1/8 inch (.125) hardened steel punch
(1) Hammer
(1) Solid Piece of Wood to Support Axle

Procedure
#1) Remove the wheel from the axle to expose the axle pin (sprocket must also be removed on 4-Series caddies).
#2) Support the axle with a piece of wood to make sure the axle is not bent while driving out the pin.
#3) Using the hardened steel punch, hammer out the axle pin. Once the axle pin is over halfway out, you can use the replacement pin to punch out the rest of the way.
#4) Align the new pin so an equal amount is exposed on each side of the axle.
#5) Reattach the caddy wheel (reattach sprocket and wheel on 4-Series caddies).
