Cerbera V8 Power Steering Pump - How difficult to change?
Discussion
Seriously?????? There is no way to remove the pump with engine in situ. Fluid level is perfect. The problem i have as i'm driving down the motorway for example so over 60mph, small steering inputs does not change the direction of the car, from what i read, if the pump base line pressure reduces (not peak pressure i,e steering full lock mode) with wear and tear then it can give the above problems, plus when you move the steering fast the steering suffers from catch back, i.e fluid not flowing fast enough in the rack which means worn power steering pump. If i do go for the electric pump route what do i do with the existing pump leave the pipes disconnected? i guess the pump uses the power steering fluid as a lubricate so i guess that would be bad practice.
Excellent the manual to me confirms the shaft is not bolted on, seems like its only pushed into position. Looks fairly easy to be honest, i just hope theres room to get it done. I will probably do it over the Easter Holidays. Can anyone confirm out there if it can be done without engine out pls.
Oh i have already bleed the system its not air, i had stripped down the steering rack last year because there was some freeplay, which is now all fixed, and at the same time i did the bumpsteer mod, i'm certain the pumps base line pressure is low as its potentially worn out. I have been reading up on how power steering work and am certain the baseline pressure is currently too low. Baseline pressure is really important especially on a quick rack style steering which our TVR's have. If pressure drops then this effects steering response, more so on a quick rack than a normal rack.
Hi i just managed to change the steering pump today, to be honest its fairly easy, just abit fiddly to get to the bolts but it was easy.
I had a spare pump but off another complete different Vehicle (brand new)_, the housing just slightly different, so i swopped the internals over to the TVR unit, i also decided to change over the relief valve and orifice outlet (output side) seems like the replacement had a bigger hole to give more flow, this is something i was after to improve baseline pressure to improve steering feel at light inputs.
Boy is it so much better! Steering feel so much improved!!! I'm not sure if my old pump was worn or not, or if the outlet orifice hole made the difference its one or the other or both.
Before the steering would jolt when one wheel went over a bump, not now. Car feels much safer at Highway speeds to.

Hi it was a long time ago but check this link you can see what the hoses look like.
