Iron horse 121 Posted October 21, 2018 Share Posted October 21, 2018 It was time to tackle my head bearing which had become a bit notchy. The wheel would self centre when lifted off the ground so definitely needed some attention. I bought a set of tapered roller bearings. It was a bit of a faff removing the top yoke with all the cables and hoses but managed to move it to one side. Stripped it down and found that it was only the top bearing that that was pitted and corroded. Anyway set about removing the hear from the bottom yoke. That came off fairly easily. The top stem outer race not too bad, tapped out with a screw driver from underneath. The bottom race had caused me some issues as it very easily got wedged at an angle and now seized in place. I have tried heat with a hair dryer, don't fancy melting the loom and hoses with a blow torch! Also WD-40 but it won't shift. I have a sealey bearing removal tool on order - in hindsight I should have got one in the first place. Any recommendations or tips on what to do next? Anyway, the forks have some nice new oil in them once I do get it all back together. Link to post
Guest machinman Posted October 21, 2018 Share Posted October 21, 2018 Gently tap it back in to the frame. Persevere, it will go back in. I punched mine out with a big blunt punch from the top. Keep alternating the blows 180° to keep it as square as poss. Ensure the bike is secured and safe and you have plenty of light, get an assistant to help. Keep us posted Link to post
fj_stuart 4,753 Posted October 21, 2018 Share Posted October 21, 2018 Phil, I feel your pain! Replacing steering head bearings is one my least favourite tasks. On the last two bikes I've done (Honda CBF250 & Yamaha FJ1200) the lower races were a nightmare. They are pressed into the frame with no way tapping them out (the uppers are ok) I ended up partly grinding through the races with a Dremel and splitting them with a chisel. Another method I've heard of is to weld a bar across to allow the race to be driven out. For the gory details see my blog here http://fjstuart.blogspot.com/2014/05/cbf-spring-clean-2014-part2.html 1 Link to post
rjp996 1,091 Posted October 21, 2018 Share Posted October 21, 2018 +1 for the dremal. I've had a needle bearing race stuck too, could not shift it with a bearing puller and slide hammer. Spent a whole day at it, until I decided to use a die grinder on a dremil and it was out in about 10 mins. 1 Link to post

Iron horse 121 Posted November 19, 2018 Author Share Posted November 19, 2018 Thought I'd report back on the steering bearing problems I was having. Anyway, I ordered a Sealey removal tool which clamps up over the top of the bearing race. 3 whacks with a hammer and it popped out. Much better than I was expecting and would recommend one of these tools as essential for anyone doing this. Same goes for the castle socket for tightening the bearing too. One gripe though is with the design of the bike. Why did the Honda engineers decide it was a good idea to run some metal brake pipes out directly under the steering bearing? The clamp unbolts but the pipes are right in the way when it comes to driving in the new race. Not helpful. So would I do a head bearing again? Yes probably, given that I now have the tools and learned a lot the first time round. However, if I'd known it was going to be tricky as it was I might have booked it in somewhere for a pro to do. 2 1 Link to post

Hi Phil, do you have a part number or reference for the Sealey tool which you used for this job, thanks, Will Link to post
Iron horse 121 Posted November 13, 2020 Author Share Posted November 13, 2020 Hi Will It was one of these https://www.sealey.co.uk/product/5637192210/motorcycle-steering-stem-bearing-race-removal-tool . I think paid about about £30 delivered from memory. Bottom race popped out with three taps with this in place. 1 Link to post

It's a bit cheaper from Demontweaks https://www.that auction site.co.uk/itm/Sealey-Motorcycle-Bike-Universal-Steering-Stem-Bearing-Race-Removal-Tool-MS040/301927919333?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 1 Link to post
Slowboy 20,446 Posted November 14, 2020 Share Posted November 14, 2020 +1 for that, and I’ve also got the bearing installer, it makes it so much easier. Link to post
djsb 491 Posted November 5, 2022 Share Posted November 5, 2022 Did you install the standard bearing races (bearing cage/balls and top/bottom races) or a taper bearing replacement (if available)? Link to post
Steve Case 951 Posted November 13, 2022 Share Posted November 13, 2022 Burgman lower head race was blind, could not see it from the top so i bought a blind bearing puller which is a finger set that expands into the gap above the bearing that screws to a slide hammer. Did the job, Sealy i think. 1 Link to post
Steve Case 951 Posted November 14, 2022 Share Posted November 14, 2022 Sorry just repeating what everyone else said. Thought i'd jump in because of the Burgman and having exactly the same issue and having to buy the tool for it. Link to post
