Pierre Gillet Posted June 7, 2002 Share Posted June 7, 2002 I plan to buy a FACOM bearing extractor. The first use will be the removal of the right hand side front wheel bearings. There are two different size extractors offered by FACOM, one being for cars and the second (smaller) for small mechanical work such as electrical motors etc.. The capacity of the "for car" one starts at 14 mm. Is it OK for the seven? Cheers Link to comment Share on other sites More sharing options...
tbhall777 Posted June 7, 2002 Share Posted June 7, 2002 You do not require an extractor for the fronts. They are tapper roller bearings. Link to comment Share on other sites More sharing options...
Taran Las Posted June 7, 2002 Share Posted June 7, 2002 Pierre, The outer races of the bearings tap out relatively easily without the need for a puller. (Conversely they tap in relatively easy too!) Phil Owen. Link to comment Share on other sites More sharing options...
stevefoster Posted June 7, 2002 Share Posted June 7, 2002 They can need a good wallop = drift. One of those nylon/rubber hammers with the ends that unscrew was the perfect size drift tool (rubber end unscrewed of course).

Pierre Gillet Posted June 8, 2002 Author Share Posted June 8, 2002 Thanks guys. You just save me 200 euros! And the dust cover ? How can it be pressed into place? A big rubber hammer too? I am envisaging replacing the bearings because I must move the nut by only half a castellation to remove the play. Would a very thin washer under the nut allow to locate the nut at a full castellation (if you understand, what I mean !)? Cheers Link to comment Share on other sites More sharing options...
Chelspeed Posted June 8, 2002 Share Posted June 8, 2002 If they're tight with half a castellation then undo it that half a castellation and the free play you have will be fine. A tiny bit of free play is acceptable and desireable. Bit difficult to describe how much is too much on a keyboard though.... Alternatively are there two split pins holes thro the stub axle? There are on mine. They'll be at right angles and the unused one will be full of grease so not easy to see. With 4 split pin holes at 90 deg and 6 castellations at 60 deg there should be an easy match without undoing the nut a full castellation. Link to comment Share on other sites More sharing options...
Pierre Gillet Posted June 8, 2002 Author Share Posted June 8, 2002 Thanks Chelspeed In fact, one castellation cures perfectly the free play.The wheel seems to rotate freely.However , launching the wheel with the hand will give 4 revolutions before it stops, while if I undo the nut by one castellation it would do 8 revolutions. Is a 4 revolution rotation a "free" rotation? I shall check the pin holes in the stub axle as you mentioned presently. Cheers Link to comment Share on other sites More sharing options...
Pierre Gillet Posted June 8, 2002 Author Share Posted June 8, 2002 Chelspeed, I did find the second hole hidden by grease. And yes, it allowed me to turn the nut by only one castellation. Problem solved! Thank you so much for your help. Cheers. Link to comment Share on other sites More sharing options...
