3. Reversing Gear Pumps (Z030f Z033, Z041)
Reversing Gear Pumps are fitted with a single check valve assembly which allows
operation with unbalanced rams.
To clean the valve assemblies, it is usually only necessary to remove the cap, spring
and ball. The dirt will in most cases be washed out with oil from the reservoir.
If the seats and 0 ring seals are removed, these are best replaced by using the cap
(without the spring) to position them. The cap may then be removed, and
reassembled with the spring in position. Ensure all parts are reassembled in the
correct sequence and nothing is missed out.
