Power Steering Leak

Nomad Z · Dec 23, 2011

LR 90 with 200tdi. My power steering has evidently sprung a leak. The steering suddenly went heavy yesterday, and there is fluid on the top of the chassis leg near the pump. The reservoir was empty, and I put most of a litre in, hoping that the leak has been there for a while and is slow. Unfortunately, it seems to be coming out quicker than 'slow'.

It will be a few days at least before anything can be done to fix it. A search unearthed a thread where it was said that driving with no fluid can damage the pump - is this the case? (Lack of lubrication from the fluid?) If so, and if I take the drive belt off and put up with the heavy steering, is it okay to drive, or is there a risk of damaging the steering box as well?

I might try the brake fluid trick in the meantime.

The pump is shot you blew seals. Remove the drive belt and you wont be able to steer it and what about the fan, alternator with out the belt? But some hydraulic oil in it and use it very little. and get a rebuilt unit.

The pump is driven from its own belt - alternator and fan are on a different belt.

On a 200, the power steering pump is on the same belt as the water pump/viscous fan. The alternator is on its own belt, driven off the power steering pump pulley, so you can't remove it, otherwise you will have no coolant circulation and you'll cook the head.

And running a pump without fluid even for a very short time will ruin it.

Not so on 200 tdi defender engine .the above pic is a disco tdi if you got a defender 200 then yes you can take the belt of the pump and drive it although it wont be fun try parking it unlles your name is Arnold!!

Inany case whip the pump out ,of with the puley press the boss off it's pump shaft and change the seal, seal No/size normaly it,s on the face of it , it should go something like (40 -18-10 example)..

Ah my mistake, forgot the Defender unit had a different layout. Also discovered today that they have a different timing set up too, and that doing a timing belt change on my (Discovery) 200 is going to cost me £20 more than it would on a Defender unit due to the extra idler!

Now I'm not sure. The engine number indicates the 200tdi came from a Disco, but it seems to have been a pukka Defender conversion. It certainly looked like the power steerring pump had its own belt, but I could have been wrong. Will check tomorrow in the daylight.

MrJ

I need a new pump as my genuine 200 Tdi Defender unit whilst it does not leak the steering is very heavy - used to be fine so I guess its the pump - I have changed the fluid but still heavy.

What sort of money are they?

Nomad, have you sorted the leak?

Mine must have come out in sympathy!
