Changed both fan support bearings on our TD5's. I had no problems with Double row angular contact 3206 European &5206 Japanese bearings I used. both were less than half the price of the uber expensive SKF and both are still going strong several years on.
From what I can see of the specs on bolt Torque.
450nm is that right?
This is seriously tight.
My manual shows it at 460nm and yes it is very tight.Quote:

Wow. I was priced $128 (Usually $180) from SKF for a 3206A-2RS1TN9/MT33 and they didn't have the 3206A-2RS1TN9/C3MT33. I ended up going with a KSM 5206-2RS as the bearing place advised the grease was rated to 120 degrees and breaking down at 180 degrees which I think has to be better than the MT33 grease. The KSM 5206-2RS was only $55 and it's made in Japan the same as the SKF. I'm told it's not rubbish but I'd not bearing expert.Quote:

If I had more time I would have ordered it from Boca Bearings in the states as I have bought a few bearings from them in the past and they have a pretty good reputation for the quality in there smaller micro bearings. Problem is I need the Disco going again ASAP so it's the local bearing suppliers for today.
Happy Days
I've had a KSM 5206-2RS fitted for about a year without issue. Freeze the shaft for a few hours, and heat the bearing in a LOW oven, they'll drop together. Then stick bearing and shaft assembly in freezer overnight. Heat housing with heatgun, run from freezer to car with bearing on a plate, it'll slide straight in.
Don't forget that there's a circlip holding it in when you're pulling the old one.... don't ask
What do you guys think about greasing the housing before fitting the bearing. I had the bearing sitting in dry ice, in the freezer and heated the timing cover with my wife's hair dryer. It only went half way and then got stick. I panicked and tapped it around with a hammer to get it out again. It's back in the freezer and ready to go again but I think some grease in the housing would make it slip in easier.
The reason I'm reluctant to grease it is if a bearing seizes, its never good for it to spin in the housing so I generally would never do it but I'm looking for others opinions.
Happy Days.
That's what I thought, until I noticed the harmonic balancer on mine had been done right before I bought it and therefore was unlikely to be the chirp on shutdown.Quote:

Joel, ditch the hair dryer and use a blowtorch (sensibly), and no grease. There is an excellent tutorial listed hereabouts on www.discovery2.ukQuote:

I talked to my cousin who is a qualified fitter and tuner and he believed the fit was tight enough that lubing it would cause a problem. What might be a problem however was getting a C2 bearing and not the C3. It doesn't make much sense to me as they should all be 62mm in diameter but C3 is a bit smaller to allow for thermal expansion. Why not have a 61.99mm instead of a 62mm, C3 spec. Then I would of cause gone "no that's too big, I need a smaller one"Quote:

I got it in in the end. It went past half way with freezing it with dry ice and putting it in the freezer but the last bit took a good hour of small taps with a small hammer. I did manage tapping away for that long without hitting the radiator so I'm happy but it was a bloody long time. In the end I was trying the cir clip every 2 minutes or so.
Happy Days.
I paid $69 + gst, but this included airbag delivery to WA, on 31/10/13.Quote:
