Hi ss ie fans, Had my bike looked over by P & H Motorcycles, Crawley, Sussex due to misfire! Which seems to have been rectifiedhowever during the test run the tech guy 'Rae' said my front wheel bearings need replacing! Is this easy to do guy's or do I need specific pullers or punches to remove the worn ones?
I would guess the same as my ST3 - easy as long as you make a tool to remove the first bearing Basically take a screwdriver and file a large v into the ide of the end so when you put it through the spindle it will hook against the iner edge of the bearing so it can then be hammered against to push the bearing out
sorry for slight hijack on thread but do you know what was the cause of your missfire as i am trying to trace one on mine at the moment and not having a great deal of success cheers johnboy
All you need is a Haynes manual and a front stand or somewhere to lift the front end off the ground. Have you got the Allen key for the front wheel spindle? No special tools needed just the modified screw driver or a punch to tap the bearings out.
You may have two notches at one end of the central bearing spacer........a long thin (say 5mm) screwdriver with a slight kink in the last 12mm can be pushed into the notch from other end of the spacer and the centre race can then be given a clump via the screwdriver.........don't forget to alternate between notches.....
Ok the tech guy said it had a rusty earth point! Near the ECU also the front cylinder was burning a lot leaner than the rear
thanks there phil another thing to check on my hit list and yep the others are right thats a cracking bike fair bit of polished alloy and is that a polished nickel frame or chrome
Just use whatever's available to you. Poke something through the spindle hole and tap the old bearing out, keeping it as square to the hole as you can, then tap the new one in using the old bearing as a drift, job jobbed. And that really is a lovely looking bike
Thanks Pete, not purchased the bearings yet might hold you to that! Also need it to get a bit warmer before I attempt the job! Also suffering from storm damage where I store my Duke so just leaving her wrapped up for the time being! Look forward to catching up soon though! Cheers
Not done you model but done plenty on KTMs. Try a socket as sometimes the OD of the socket is the same as the ID of the bearing and goes through the spacer to knock the old one out. Also try heating the wheel hub with a hot air gun (not too close) to warm and this expand the hub to make the bearing fall out easier. Keep the new bearings in their packets in the freezer overnight then again heat the hubs and drop in cold bearing. You can use a different socket that only sits on the outer race to refit unto the shoulder in the hub. don't forget to put in the spacer before fitting the other side bearing. Just remember to only hit the outer race of the new bearings !
Oh that's what that big white thing in the kitchen is for! Thanks for that advice! I guess it makes sense to heat it up before slipping it in! Ooopps maybe I should'nt of put it like that!
Wheel bearings tend to be pretty easy out / easy in on all six wheels I have done.................the main thing to watch is that the spacer length doesn't interfere with the bearing sitting home, but even more importantly, that the spacer isn't too short and the bearings inner races can't get pulled together.........Check that the wheel spins easily when they are all installed and tightened up.
Front wheel bearings now fitted! Gonna test it today! I took the front wheel t my friendly bike shop 'T Northeast' in Horley, Surrey he got the old ones out! He said they were very well seated, he did have to apply heat to remove them! Only charged me a fiver, so I rounded it up! I could not of managed this at home, not got the blow lamp etc..... Happy now fixed! Next job Brake pads!
