Thread: 300TDi centre idler pulley - fan hub shaft - bearing

There is a replacable bearing and the timing case cover does not have to come off. The bearing is the same as the other two idlers, so it is wise to replace all three at the same time - then you can forget about it for another 100,000kms or so. KBC Bearing part No. is C3G14 (not sure what genuine is) and they were about $7 each a few years ago. Dimensions are 40mmOD x 17mmID x 12mm wide. The one that you seem to have the trouble with is a bit tricky to get off - it's been a while since I did the last one and can't quite remember what the trick is - but there IS an easy way so give it some thought before racing into it.

this is the one that has the shaft the fan screws onto....

Oops sorry - picked up on the word 'idler pulley' and went off without reading your post fully.
Looks like yours is a more complex job than just the idler pulleys.

The fan pulley bearing in made by INA, but you can't buy them separate from the front cover - over $400.

If the bearing is just a bit noisy, pull the cover off, you will see a seal that can be removed (if you are careful) from the bearing, then flush the bearing out, pack it with long life grease, then re-fit the seal.

The bearing in the air con compressor clutch is a common deep groove ball bearing with seals both sides - sorry can't remember the number.

Inc, genuine is the whole timing cover. I replaced mine as a 'just in case' @ 178,000km when I was doing the timing belt back in January, cost $440 incl., then three weeks later saw one of the Aussie ebay vendors have the correct bearing on it's lonesome for approx $80-90...........

Thats more like it. I could not see Land Lover going into the bearing business for a one off special.

It is part number ERR7146BRG, price is $115.50

You will need a hydraulic press to do this job. When replacing the bearing, the bearing together with the flange that the pulley bolts to must be pressed out of the cover together. Then the flange is removed from the bearing. If you try to remove the flange from the bearing while still in the cover you WILL BREAK the flange. Any workshop with a press will be able to do this job for you.

thanks alan, much appricated.

i dont have access to a press or the time to take it on myself at the moment, so i have booked it into MR Automotive at redcliffe to do the job.

the fan hub is cracked as well from what i can see but i will have another lookeesee in daylight this afternoon.....

just got to throw it back together so i can get it down to them...
