A few days ago I disconnected the power steering pump from the drive system, but removing the belt and replacing it with a shorter belt to just drive the alternator. I did this because the pump is knackered, and I'm trying to sort out what's gone wrong before replacing it.

Since disabling the pump the fuel economy has improved, and it hasn't been bothering me (although parking is a pain!) and I'm toying with the idea of leaving it disconnected.

If I do this, will there be any medium to long term implications in terms of increased wear to the steering rack / steering column bearings?

 

its not gonna pass mot , thats a bit ov a problem me thinks

 

yeah it will probs put excessive wear on the rack and bald your tires and wear the bushes quickly too on the upside u will have forearms like popeye lol

 

its never gonna pass mot with pas not workin lets be real

 

Should make steering lighter if you remove fluid as you are pumping it when you steer.
If it was all removed and steering usable why would it fail an mot?

 

Can't see why it would fail if the whole PAS system was removed, they can't fail it on something that isn't there !

 

So not being able to apply as much load to the rack will achieve all this how exactly?

Confucious he say man with no idea better off keeping mouth shut, that way foot not enter mouth so easily.

I know of a scoob that has removed all power steering pumps etc, and is running aound with an MOT just fine.

 

hello he says he has disabled the pas pump its still fitted he's just running smaller drive belt thats not running the pas pump so thats a fail, agreed if he was to remove the pas altogether fair enough but thats not wot he said

 

I was thinking similar but you said it so much better than I could have

Where in the MOT book does it say check the PAS system is to be working? All the MOT does is check that there is not excessive play in any part of the steering system. Working in the motor vehicle trade I used to do pre-mot's (was not in a position to hold testers ticket). I did have full access to all books used and requirements.

 

Thanks for the advice everyone

Regarding the MOT, the following page states that 'Power steering systems are checked with the engine running'. This may simply be a statement of the obvious (you wouldn't check the steering with the engine off if PAS is fitted), but it does have the word 'check' in there so I'm not sure!

MOTester.co.uk - The MOT Test and UK MOT Testing > Car Owners Guide to The MOT > What Is Tested?

 

there is another with commom sense on here thank god,

 

Yeah.

If something's fitted (whether OEM or not) and it's not fitted correctly/unsafe/don't function as it should = fail

If totally removed safely and correctly... nothing to test = can't fail.

I've removed the front foglights and switch - no problems with MOTs... as they're not present to test!
