Tucker steering pump (Vickers)

[Eric L]

Is this thing missing parts? Seems like there should be a baffle in there or maybe even a filter.

I've been having probs with it aerating the fluid.. didn't do it much when I first got it, but she hasn't seen much use either.

should the reservoir be vented or sealed?.. I would assume the fluid needs room to expand with heat and the level would change as the steering cylinder moves... but it leaks bad enough as it is (mostly from the aeration)

Thanks,
Eric

you should have a top and a cap either the cap wipp have a vent hole in the top or a popet valve in the cover also i 'm not real familiar with the tucker but to blead most hydraulic systems you need to run lock to lock to blead cylinders also on the hummwv's especialy armord models we had to jack the wheels to cycle the hydraulic systems to get the air out because there was too much load on things and the pumps would cavitate and never blead you may have to do that with your tucker or you may have a bad pump.

OK.. I took the cap off to show what was (not) inside..

I have not ruled out a pump failing, but with the engine running the fluid is like a gusher coming out of the return hose and hitting the cap (and theoretically making bubbles?)... at higher RPMs i'd bet it would shoot higher than the cab. I'm planning a baffle of some sort to test.

I disassembled a reservoir from a heavy-duty truck and it had all kinds of cool stuff inside.

I added a small baffle over the return port and another flat plate about 2" above the bottom of the reservoir. I call it the "percolator".

Sure seems to make a difference, I can run and steer (in the shop) without the cover on the can, even at high RPMs. no signs of aeration at this time.

was tempting to take it out tonite, but wouldn't have proven anything without taking it for a longer drive than I can give it in the neighborhood. Maybe next weekend or the weekend after.

Well it seems to work just fine now.

Took it out on Sunday and all was good in the steering department.

now onto new exhaust, some electrical upgrades and track repairs (money permitting).
