Re: Nexus 8 cassette joint damaged

Reporting back - I re-fitted the original CJ-8S20 reaction arm. When I removed the CJ-8S40 the waterproof boot seemed quite 'draggy' on the cable. I replaced the cable and set it up very carefully using the Shimano tool TL-CJ40. I noticed that the cable housing run underneath the bottom bracket was ...

Re: Nexus 8 cassette joint damaged

Thanks for that Brucey - I have CJ-8S40, so I'll remove the rubber boot and test the bike before carrying on with the procedure.

Re: Nexus 8 cassette joint damaged

Brucey - I couldn't get the yellow marks to change using the shifter and if anything the chain is a bit loose. When I unhooked the cable from the cassette joint I noticed that the rubber boot was right round the pulley and almost touching the bit where you insert an allen key to move it against the ...

Re: Nexus 8 cassette joint damaged

Thanks Brucey; I'd be really obliged if you would as I have had four years of bother with this bike. It's like Groundhog Day :( .

BTW, the yellow marks are stuck between 5 and 4 in both directions.

Re: Nexus 8 cassette joint damaged

Well I rode 105 miles before gears 2,3 & 4 slipped. Before I even slacken off the axle nuts to investigate, is there a systematic procedure I should follow in order to isolate the problem?

Re: Nexus 8 cassette joint damaged

Brucey - as far as I can tell the reaction arm is not moving at all when I change gears, at least in the workshop. If/when I lose the gears again I'll look for wear on the hub fitting. I've had the wheel off so many times I've stripped the axle nut threads, so am waiting for new ones along with a ne...

Nexus 8 cassette joint damaged

This hub is fitted to a Cube Travel Pro 2016 model chain drive bike. It can run smoothly for up to 70 miles, but then when I shift from gear 5-4 I lose gears 1-4 completely. I dismantled the hub assembly to have a look inside and it was very clean and there were no signs of wear or damage. I dipped ...

Re: Nexus 8 still slipping

Brucey - I should have said that the tangs are pointing to the open end of the dropout so are under the axle when the bike is upright. When I released the axle nuts that freed up the yellow marks. They were correct when I moved from 1-4 but way out when I moved from 5-4. With the axle nuts still loo...

Re: Nexus 8 still slipping

Brucey - the bike was upside down when I took the photos, so the tangs are under the axle. Today I rode 18 miles without slipping, but when I got home I checked the yellow marks. Initially they were correct but as I repeated the test they started to go way out of alignment, then stuck completely goi...

Re: Nexus 8 still slipping

Brucey - When I re-fitted the wheel I initially tightened the axle nuts by hand. The left hand nut was snug up to the cone locknut, but there was a 5mm gap on the right side. This meant I could see the frame moving as I tightened the nut with a beam wrench. I wonder whether there should be an extra ...

Re: Nexus 8 still slipping

Well I rode the bike for 40-50 miles before it slipped again in gears 1-4. This time I removed the innards and dipped them in ATF. Everything looked as good as new and the ATF has mixed well with the grease. Once again when I re-assembled the wheel the yellow marks lined up perfectly from 1-4 and 5-...

Re: Nexus 8 still slipping

Brucey - I've ordered some of that Land Rover swivel grease. Two questions:

a) Should I wait for a while before adding it while the ATF does its work?

b) Will it be OK to just add it to the hub without removing the innards?
