This coming weekend I'm going to remove the part of the Haldex 3 unit that attaches to the drive shaft so that I can remove the pump and check if it works yet as I'm about to put the AWD unit all back together before the weekend.

My question is this, when I put this piece back on, I'm assuming it needs to be torqued to a certain value, does anyone here know what that value is? Also, is there a preload torque valve that I should know about as I'm assuming there is a crush washer inside this unit.

I hope this makes sense, looking for insight.

Thanks in advance,

Matt

I can't find any torque values, just 'snug'.

This is a nice but long write up:

Keeping it running is better than buying new

Thanks KlausC,

I just finished reading this thread.

The torque value is 110 ft-lbs. I got this by asking XeModex in Canada, what the value is, and that was the response.

I've replaced the filter, pulled the pump and cleaned its filter, which was not dirty at all, then added clean fluid. Not sure the oil was ever changed. Bought the car with 198k on it, and I now have 204k on it.

The rear diff fluid has been changed as well, and it was awful as well.

This weekend I tackle the transfer case rebuild. I pulled one out of an 06' S60 this past summer. It was leaking badly, and its bearing's were shot, so all of them are now off. The ring, pinion, and ring gear splines are in great shape, and to boot, this design has new beveled edge on the inside which makes for a better sealing.

I also had a bottom drain plug added to the unit so I can just drain it straight away with out having to suck oil out and then push oil back in.

Fun times!
