Remove the retention pin from the top of the case. Insert a hook into the lifting
eye located on the top of the weight. Lift the weight out of the Post Driver with a
hoist, forklift, or another vehicle. Set the weight on the ground.
Carefully lay down the Post Driver on its front side.

Remove the retaining ring fastened to the lower sprocket shaft assembly, and pull
out the shaft from the opposite side of the Post Driver.
Remove the tensioning rods and shim(s). Slide chain slack to the top of the Post
Driver.
Find the chain catch and two pins that secure it. Remove the clips that retain the
pins, and remove the pins.
Install new chains over the upper sprocket shaft assembly. Make sure open ends
of the chain are at equal links away from sprockets.
Reinstall the chain catch and pins through the open ends of the new chain. Install
clips on the pins.
Slide chain slack to the bottom of the Post Driver, and insert the lower sprocket
shaft assembly into the chain.
Shim(s) must be inserted between the tensioning rods and the lower sprocket shaft
assembly to maintain proper sprocket location.
Insert the lower sprocket shaft through the side of the Post Driver and through the
tensioning rods and sprockets.
Install shim(s) and retaining ring on the end of the sprocket shaft.
Install bottom chain guard and tensioning springs. Tighten tensioning nuts until
the springs are adequately preloaded but not entirely collapsed.
