SERVICE
DISASSEMBLY
Before disassembly of pump, remove reservoir filler cap
(when used) and drain oil from reservoir by inverting the pump
so oil may drain out the filler hole.
After oil is drained from reservoir, cap should be replaced
and the entire pump assembly washed in a non-toxic solvent
to remove all dirt and prevent any foreign matter from
contaminating pump components.
1.
Clamp front hub of pump in vise so that the extending
portion of shaft is directed downward, being careful not
to clamp vise too tight as this may distort the bearings.
Use soft jaws in vise if available.
