Drive shaft check

Bearings in. A doddle. Freezer and heat again but really not that much heat, just so you can touch/hold for a short moment.

I need to pull my paralever soon and check / service it.
If bearings need replacing, Motorworks can shut up and take my money!
These look GREAT!
good write up too
 
Aren't those paralever bushes the same as those that caused problems on bikes on the ADV rider website.. ?

They might be! I haven't checked ADVRider on this particular story. What kind of problems?.

I'm happy to give these a go. Now I've done it, I can see is not a huge job to change them. They are less than half the cost of the taper bearings and new pins...

Off out for the test ride now. Hopefully no luck needed

I don't think they are Neil. The ones on adv were just machined bushes to replace the bearings. These look to be better engineered with custom pins etc
 
Just a note on the slow rhythm that people talk about. After much deliberation, I reckon it's tyre wear/blocking which gives a harmonic beat due to the different wheel sizes. I'm on original Tourances and wondered if anyone had noticed a change when they fit new/different tyres?
 
Back from the test ride. What a difference. All symptoms have gone. Tracks beautifully at slow speed, absence of the little rhythm. Clearly I had been compensating for the change in handling. I'll have to compensate back over the next days .

I remembered one last specialist tool . To reinstall the FD splined shaft into the main drive shaft I used this (along with some choice words, it is a fiddle that bit!). It's not my idea, read about it on here I think, but I added the cable tie to the idea. Cloth stuffed under the main shaft to get it roughly central. Once FD engaged, pull the cable tie to retrieve the cloth. Worked well.

As for the ABS sensor gap. After a search it seems the gap for iABS is up to 1.7mm? Which means mine is well inside that. And no faults were displayed.

And while I remember, torquing the adjustable pin proved more tricky that I expected. The instructions tell you to bottom out the pin, then back off 1/4 turn. That all seemed too tight to me so I backed it off a little more. With the torque bar disconnected, I checked the movement. Same again with the wheel on. I'll be keeping an eye on it over the next week or so. The nice thing is being able to add some lube if needed.

Hope this has all been useful for anyone considering the same job. Someone like Steptoe or Mikey would get this done in half the time it took me, but at least I know what to do now.

ps. It looks like Steptoe is the one I need to thank for the rag trick (thank you Packer for your early post ref. refitting the FD)

The ones on ADVRider you mention.
From memory were just Phospher Bronze bushes from Rubber Chicken Racing.
The last time i looked at that article, it seemed to me that there wasn't much benefit and some had converted back to regular roller bearings as original.

These how ever look better than both.
The cup will stay in place, filled with grease, pump appropriate grease through the pin which will then fill the cup.
There will then be a filler of grease between the pin and cup which is how lubriacation works - a fluid medium between two working surfaces.

Any update of miles/wear of the MW bushes????
 
The bushes are no longer available from MW. I wonder why?
Do you mean the phosphor bronze versions?

I see that I started this thread almost exactly 2yrs ago.

I'm pleased to say the bushes remain spot on. Not one iota of discernable play (I can't 'feel' any movement whatsoever). I had the torque bar off just a month ago to try and get a little more grease in. I couldn't. And the FD moved up and down very smoothly.

So a thumbs up from me. Oh, that's 2 winters, two 3k+ Italy trips and some commuting. Roughly 15k miles.
 
Glad theyre holding up well Rodin. Yeah i meant the ones you linked to - went on to MW to have a look and theyre no longer available for sale.

The OEM BMW ones usually last for 30k, so come back after another 15k and tell us how you are getting on

Agreed. I'm not even half way through what should be a much longer life expectancy than 30k miles (IMO).

But so far so good. Which I am of course very happy about after having to fork out to get the rear shock rebuilt at the 11th hour before I head off! Argh.

Any ideas why MW stopped them? Sourcing issue or complaints?

My original bearings have been in for 16 years and 70k miles 👍 Been greased a few times over the years though .

That sounds more like it

The bushes need greasing too. Sounds like the message is, maintain it

Still interested in how long these bushes will last. I'm afraid you're all gonna have to wait for a few years for my feedback though
