Help ID Crosspoint screw-in fittings on pump body
(OP)
Hi guys:
I'm trying to find the correct tool to remove the crosspoint/philips-like covers on the radial pump shown in the attached picture.
It is powered by the engine of a rally car and used for operating the power steering and the hydraulic shifitng of the manual transmission. Size is about 3 inches diameter and about 10 inches long, mounted on the engine block with multi-v belt connection.
The pump was made by Toyota Team Europe in the mid/late 1990s and I'm trying to get it operating, but it now has no pistons (other internals/eccentrics/one-way valves are ok, I think).
Any idea as to the tool used to remove (unscrew) the caps/covers over each piston bore? Covers are about 3/4 inch dia, but probably metric sizing. The pump body was made in-house, but the caps appear to be commercial - die cast, etc.
Thanks for any help you can provide. Bruce

Snap-On used to sell sockets (basically big screwdriver tips) for wrenching stuff like that, but I couldn't find them in the online catalog, and you didn't give us measurements of the cross recess dimensions so I gave up looking.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

A screwdriver blade was too thin and was buggering the slots on the screw-in covers so I bought a 5/8 in cold chisel and ground the tip to fit the slot. The chisel has a hex shank so I used a box wrench for leverage to remove the screw caps.
Interesting that current ZF radial pumps now use only a single slot in the covers not a cross.
Thanks again for the suggestions! Bruce
