I got my tyres after some unnecessary shenanigans. I was let down by the first suppler who accepted my money then contacted me a day later to say the tyres weren’t in stock so they were going to give me a credit. I checked their website and, lo and behold, the tyres were still listed but had gone up in price. I considered this to be sharp practice and told them so. It meant that I could actually get the tyres elsewhere for less than their new price so, that’s what I did and insisted on a refund. I wasn’t bothered by a 4-day delivery time. It took 2 days for the original company’s accounts department to process the refund which then took several days to reach my account. To top it off they asked for my feedback on resolving the issue before I’d even got my money back. I told them what I thought again. Oh, and I promised I’d give them a mention here so, Pneus Online you get a definite thumbs down from me.
Now I’ve got that off my chest let’s get back to the task in hand. As the rear tyre was pretty near bald I decided to tackle that one first. Here’s my tyre changing kit. Tyre levers, bead buddy, valve core remover, rim protectors, tyre lubricant and powder to stop the tube sticking to the tyre. The thing with the yellow string is a home made tool that screws into the valve stem to pull it through the rim. I’ll buy the proper job when I see one. Also on hand was the garden spade. More of that later.
I’m not going through the process of changing a tyre as there are plenty of helpful videos on you tube. This time I’m going to try and get the rear wheel out without having to remove the exhaust. I’m lucky in having a lifting bench with a trap door which should allow the rear wheel to be dropped clear. I managed to get the bike secure on the bench without having to call for assistance.
Ground clearance was an issue when I wheeled the bike onto the bench. The “washer” welded to the side stand caught on the bench top as it went over the crest.
The one thing I did take off was the left hand pannier to give me access to the brake rod etc.
You can see here that, if I want to drop the wheel completely through the hole in the workbench, the ramp will get in the way.
That ramp was soon off.
Now to actually get that wheel off. I’m sure I’ve described this before but never mind. First thing is to disconnect the brake pull rod from the brake hub by undoing the knurled adjuster.
Then the brake torque arm has to be disconnected as well by removing this nut. The fixing at the other end to the swing arm has to be slackened as well before it will come off and that end is difficult to get at with a non-flexible wrist like mine.
I then remove the spindle/axle securing nut before undoing the clamp bolt on the swing arm shown here. I use a big old screwdriver to get everything moving.
Before pulling the spindle out I removed the plate from the bench but put a bit of timber across the gap until I was ready just in case.
The spindle now comes out but I hold the wheel and brake hub against the drive box while turning the brake plate so that no nuts can catch when I pull the wheel toward me off the splines to lower it away from the bike.
I came across a problem at this point. I found that the complete wheel assembly was too heavy for me to manage and, having come this far, I had to come up with a solution quick smart. I decided that, with that bit of wood holding the tyre up, I would lower the bench halfway so that I could drop the wheel through the trapdoor and against the frame of the bench. I was able to take the brake hub off before jacking the bench back up a little at a time until the wheel was free. Where there’s a will…
The actual changing of the tyre was interesting! It was an absolute fight to get the old Michelin tyre off. Breaking the beads was easy enough. I did it the way I always have using the garden spade and jumping on it! After that I spent ages. I could get the first bead over the rim but the second one didn’t want to play. In the end I took both beads off so the wheel fell down inside the tyre. I then had to rip the wheel out from the middle which took all my strength. However I did it without causing any damage to the rim or me. I wasn’t pleased to find that the new tube I had given the tyre fitter (I wasn’t able to do the job myself following my broken wrist) had 2 patches on it. He’d obviously had some issues then! I cleaned up the rim and fitted my new tyre. How easy was that? Only one lever was needed to get the first bead on and two for the second one. There was no heavy levering needed and it was safe to dispense with the rim protectors. Perhaps it’s because these are tube type tyres and the old ones were tubeless but used with tubes. I don’t know but, this is how I remember it used to be.
I got my home made tyre balancer out and was pleased to find I only needed 30g of weights. The old tyre had a lot more than that.
Here are old and new. The new tyre looks a bit wider but isn’t. It’s just because that one’s mounted on the wheel.
While the brake plate was off I checked the linings. They are still good (4mm). I had begun to wonder because I had run out of adjustment on the brake pull rod.
Much to my surprise getting the wheel and brake plate back on the bike was easy enough. I was able to stand behind the bike, reach through the bench and lift the wheel up so I could shove that bit of wood under again. Maybe I could use this technique to get the wheel out next time. So with the wheel back on the drive splines the wheel spindle was put back in place. The brake torque arm needs to go back on before tightening the spindle nut, then the clamp bolt on the swing arm.
As I’d run out of brake adjustment I decide to move the lever on the brake plate. I marked it’s current position before removing.
Then I refitted it turned one spline.
The brake rod was then refitted but to do this I had to lever the arm round a bit first so that I could get everything properly located.
Now I was able to adjust the brake to give about 10mm free play at the pedal and with the bike back together I reassembled my bench.
Front wheel next time. That’ll be easier, right?
