300Tdi Power steering pump - how does it mount?

[VladTepes]

Driving and suddenly squeals from the engine bay and alternator light comes on.

Investigation shows that no tension on serpentine belt, and the power steering pump is flopping around like a fish in a bucket.

Can anyone point me to an appropriate diagram showing how / where it is supposed to be secured, and what particular fasteners are required?

Thanks

Here is the problem:

Are these supposed to line up and have bolts in them or something?

Yeah you appear to have lost a couple of bolts, the pump bolts to a bracket and that bracket bolts to the timing cover.

[VladTepes]

Any reference as to the parts I need to buy?

No but they are just bolts, take one of the existing ones out and match them.

I don't remember exactly how the pump mounts up on the 300TDi but there may also be some bolts deep inside the alloy holder that the pump is sitting in. If the outside bolts fell out I'd definitely look closely once you've got the pulley off and the steel plate out of the way. From memory all the p/s mounting bolts are M8 by 20mm or thereabouts, LR use 10mm heads but normal 13mm ones should fit. A dab of Loctite on the bolts won't go astray.

you appear to be missing at least 2 of the 3 mounting bolts that secure the pump to its mounting bracket. (video wont load for me ATM Im making the assumption off of just the photo)

if you're lucky they have just worked their way out, if you're unlucky they have snapped.

to replace them as is you will need to remove the pully from the pump and as the serpentine belt wont hold the pully for you you will need a filter strap to hold it while you undo the bolts.

from memory the 2 bolts should be m8 1.25mm with a 30mm length. they are a shouldered bolt and are suspiciously exactly the same as the longer of the short bolts that hold your water pump in place (IE not the ones that go through the pump, housing, p gasket and into the block) as well as the bolts on your timing cover.

I was hoping I could get away without removing the pulley - bugger eh.....

[VladTepes]

While we're at it is it easy to remove the fan shroud?

[PAT303]

It is after removing the fan. Pat

you can, but it substantially increases the "fun" factor. Its one of those things I'd do just to prove it can be done, not how I'd recommend doing it.

depending on why you want to remove the shroud its easier to remove the fan, the only reason I wouldnt pull the fan to do it is if I was pulling the shroud to replace the radiator only. Then I'd unseat it to allow the radiator to be pulled, the only justification for doing it that way is that you dont care if you damage the radiator on the way out.

I remember Gav (Bacicat/Homestar atm) helping me replace one of these, without removing the shroud. ***** of a job, but got there in the end. If the bolts aren't snapped, surely it shouldn't be too hard to put 2 new bolts in (perhaps with some Loctite this time)?

If you want to pm me your address, I will try and get over this afternoon and have a go at fixing it for you.

Does the PS pulley actually turn
Is it possible that the PS pump has seized, thus loading up and shearing the retaining bolts?
Well what most likely happened is they tore out of the alloy housing?
If the pump has seized you will want to check the PS circuit for metallic badness

I would be pulling the shroud and fan off in order to reduce the swear jar donations...

Yep, seems to,

Got it fixed, up and running.

Thanks so much Tony !!!!!!!!!!!!

He's a top fella, helped me out a few times now ;)

I got my "LR fix" for the day and finally got to meet the infamous VladTepes.
What more could a bloke want.

So 2 bolts went awol and the 3rd snapped.

"So 2 bolts went awol and the 3rd snapped."

Any ideas as to why? shaft runout? pulley/belt not running true? hydraulic blockage in steering box?

Seems a little weird to just happen out of the blue. 300tdi PS pumps can be pernickity at times...

[Blknight.aus]

howd the third break? flush or with enough showing to make getting the rest of it out easy?

did you manage an in situ fix or did you have to pull it down a bit?


Additional FYI.

I just remembered, there should be 4 bolts holding the metal plate that the pump mounts on onto the ally support housing, you should be able to rat 2 of them as an emergency fix.

[jboot51]

The bolts in question are the three that hold the pump to the bracket.
1 bolt has been missing for a while, the plate was rusty.
Another has recently vanished, the plate was still shiny where the bolt head should have been.
The third snapped off flush with the pump.
A small piece of the pump housing from around one of the threaded holes was also missing.
I had a spare pump that we decided to install.
Easy fix, got lucky with undoing the viscous though. Not the easiest without a fan belt to hold the pulley.
Everything seems to be in order with the rest of the pulleys etc.
Possibly the bolts were never torqued up and just came loose over time.

finally got to meet the infamous VladTepes.


A highlight of your life to date, no doubt :lol2: :lol2: :lol2: :lol2:




Infamous eh? I've been called worse.. :D

[VladTepes]

Going back I found out that a new power steering pump was fitted shortly after I bought it (Nov 2013) and the usual "Australian cost". Grrrr.
