There's a notch in the steering and the MOT is coming up so I thought it would be best to replace them before in case it fails on it.

I don't want to take it in to a mechanic for them to do it and charge me a bomb so I'm doing it myself.

I'm a noob when it comes to doing something like this so any tips on how to not ruin my bike would be helpful. Would mainly like to know if there are any specific tools that I could do with having before attempting this.

Thanks

C spanner, drift (steel rod), tin of grease, a piece of metal tube (hoover tube works), a dremel if you've got one, if not an old knackered chisel and the right sockets or spanners to get the big nut off the headstock and to undo the clamps where the yokes grip the fork legs.

edit- a hammer

Remember not to tighten them too tight, as this will knacker the bearings, you need to take up the play and no tighter.
Good Luck.

Not really and anyway, the fork seals were replaced only 1 or 2k miles ago.

Thanks for your replies Thumbs Up

Im doing this sometime soon on my 125.

anyone happen to know what size the bearings are for taper rollers?
do they need seals?
Plan to get them from local bearing shop rather than a motorcycle place.

TIP:

Dave Silvers do Taper-Roller kits; they are about £25; they fit; they come with upper and lower seals, and make the job nice and easy and hassle free.

If you go on e-bay; you can get taper bearing kits for about £15 +p&p.

If you c an get dimensions, and go to a bearing stockist, you might get the bearings seperately for perhaps £5/6 each.

I have done, on different bikes all three. And yes, savings going e-bay or local bearing supplier can look worth while.

BUT saving is, in reality bog all. At best its £15..... e-bay or stockist, lack of top and bottom seals means messing around trying to salvage old ones or loose savings sourcing them seperately; risk buying e-bay kit or loose bearings is that they are a tad too tall for stem length meaning grinding down lock nuts or stuff..... and possibly petrol to find and fetch, and hassle either way.....

For such a small saving, and for a first timer / ameteur on the job; that extra tenner to get 'the bit for the job' with confidence its a hassle free fit, with come back on reputable supplier if it ent, is worth that small saving. DIYing it, you are saving big money over sending it to a pro, ANYWAY.
