Thread: 300tdi Viscous Fan Bearing - SOLUTIONS!

I'd be taking the pulley to a wreckers and see if you can scrounge a stuffed pump off them to match. The bit that matters is the locating ledge that centres the pulley and the Ford one is very close, requires a half mm or so off it. Dead Fords aren't exactly rare.

One thing that seems to have been missed is that the shaft of the original bearing (in my case anyway) is approx 5/8in while the Koyo or JD shafts mentioned in the thread are approx 3/4in (which from checking bearing catalogues is "standard" for a 1.5 in OD water pump bearing).
So if you have managed (as I have) to get it all dismantled without breaking the original flange, it will be necessary to machine the flange to suit the Koyo/JD bearing unit.
Just something to be aware of.

Both the Koyo bearing I bought and the Ford bearing have a 5/8" reduced shaft at the pulley end.

Can I just confirm that the rear of the timing cover where the bearing sits, has an access to the bearing to be pressed out.
I did my timing belt a while back and can't remember seeing access to the bearing .. but then again I didn't really take a lot of notice of it.

Or is the bearing pulled out of the case from the front?

Reason I ask is that I think there is a bearing and flange available ready made for the job, that requires no cutting, filing, chamfering, or no other hacking of any kind, and I'm just making sure I can press the bearing out easily when the time comes to do it.

And if anyone has the length value of the standard bearing.

Bearing I've found has an apparent size values of:
length = 75mm
shaft = 16mm (5/8")
diameter = 38mm (1.5")

The flange appears to be identical to the LR forged type(4 armed) and not the machined Falcon type.

Bearing is a VE/VF/VG(95-00) Transit bearing that appears to be identical in size specs to the LR type and fitment is similarly pressed into a case, in the the Transit it's the oil pump cover case.
The bearing has a sealed rear end, without the shaft extending out the back like in roverrescue's first post of the original SKF bearing.

There's is a parts store(H&B Auto parts) just a minute or two up the road from my place that sells Transit van parts, so I'll pop in and check the parts out.

Prices are about $58 for the bearing and $40something for the flange. ie. about $100 all up for both parts, but are separate.

I reckon it's very likely that the parts in the Transit are the same as the 300Tdi, going by the quoted dimensions.
So it seems where LR refuse to sell these bearing/flange parts, hopefully Ford are an option.
Note I've tried to track this part down in Ford parts searches, but have no luck at all.

If someone else wants to have a peek, or has access to better parts searching via Ford parts catalogues, the part numbers I've found are:

Bearing: 974F- 8A641-AB
Flange: 864F-8K600-AC

My thinking is simple: if the parts are the same(which I reckon 99.999% likely to be), then get the parts, press flange onto bearing, press bearing into case, and done .. no mucking about(which I prefer not to have to do).
Then, hopefully find cheaper parts via Ford or something.

I'm also going to ask at my local R&E Auto if they can get these VE/VF/VG Transit parts as well.

The bearing can be pushed from either direction.
I push the bearing from the front as there is more room to support the housing from the back.

Awesome!
So the rear of the timing case is clear for the bearing to pass.
Like I said, I had the case off, cleaned it out and all that .... just can't remember seeing the backside of the bearing.

I'm thinking that if you push the bearing from the front, out towards the rear of the timing case, you need to remove the flange first?

The rear of the case is clear.
I removed the flange using the nut from an old viscous.
It may pay to heat the flange as I have since broken 2 flanges
Have a look here I posted some pics.

Yeah, I remember seeing your thread on the bearing replacement .. just couldn't find it again.

Going by your measurements of 47.25mm and 26mm for the bearing body and shaft, adds up to 73.5mm total +- 1.5mm is close to the 75mm length of the Transit bearing .. so I'm even more confident that the Transit bearing and flange is going to be the same as the LR part/s.

I think I kept my old viscous unit, so could probably make up a puller with it .. otherwise may just find some odd bits to make one up. (eg. find a large nut to fit, weld it to some plate, drill hole into plate and thread it .. etc)
