Migthy Mule Posted August 22, 2012 Author Posted August 22, 2012 Yes I tried the seal that way round in desperation - I thought it may be fouling in the hole, I have it the right way round now
Migthy Mule Posted August 22, 2012 Author Posted August 22, 2012 oh and definitely only the one seal, my photography is a little poor
Migthy Mule Posted August 22, 2012 Author Posted August 22, 2012 Im going to see if I can find the old seal, but its a bit late now ill keep you posted, thanks
Moderator Airhead Posted August 22, 2012 Moderator Posted August 22, 2012 why the old seal, why not the new one correctly fited?
Migthy Mule Posted August 22, 2012 Author Posted August 22, 2012 Ill post some photos tomorrow and see If its any clearer
Migthy Mule Posted August 23, 2012 Author Posted August 23, 2012 Ok here we go Yoke showing shoulder Grease seal in place Bearing in place Cups driven in to shoulders Top bearing in Stem in Top seal on Drawn up with threaded bar lock nut on 5-6 mm gap between top of stem and top of yoke. I have just re fitted it with the old grease seal which has given me an extra mm or so, see image below
Moderator Airhead Posted August 23, 2012 Moderator Posted August 23, 2012 thats not good! The castle nut should be pretty much filled with the stem thread The old seal fits around the shoulder doesnt it, thats why you gan a bit extra there. are both the new seals the same with the same sized holes through them? of course if you rough it together with no seals you should have lots of stem thread available...if not then the bearings are no good! ?
Migthy Mule Posted August 23, 2012 Author Posted August 23, 2012 Yes you are correct the old seal fits around the shoulder but omitting both seals only gains me about 2mm I have tried the seals every which way even the wrong way up the holes are the same size. Think I am going to order some more bearings, can you recommend a supplier I was going to go through Yambits

Think I am going to order some more bearings, can you recommend a supplier I was going to go through Yambits by all means use yambits but why not ring them and speak to Dave (mr Yambits) talk to him about all the issues you are having with this
Migthy Mule Posted August 23, 2012 Author Posted August 23, 2012 Thanks Thats a good plan, Ill keep you posted
Migthy Mule Posted August 24, 2012 Author Posted August 24, 2012 Just spoke to Dave, apparently the tapered bearings are slightly taller so he suggested I order the original ball and race bearings, thanks Paul
Sacha Posted August 24, 2012 Posted August 24, 2012 Well that's kind of a pisser isn't it? Isn't a reason behind getting the tapered ones to get away from the older style? Hmm I hope I don't run into that.
Moderator Airhead Posted August 24, 2012 Moderator Posted August 24, 2012 mine has taper ones fitted and i never had an issue!
Migthy Mule Posted September 8, 2012 Author Posted September 8, 2012 Hi all got the new bearings today Looks like thats my 5mm, very strange parts in the freezer, hope to have it back together tomorrow happy days
Migthy Mule Posted September 27, 2012 Author Posted September 27, 2012 Hi, yeah all good. after assembling and disassembling it so many times the whole thing went together in about 20 minutes. came across another issue (see topic - front wheel alignment) set out for its mot last Saturday but the gear shift pedal broke before i got to the end of the road fingers crossed for this Saturday
pyro plim Posted September 28, 2012 Posted September 28, 2012 I have the top and bottom yokes of a ct1 if they fit? in good nick if any use.They were not on taperd bearings but i beleve you can fit them .Looking at your pics the replacement bearings look wrong anyhow good luok i am only near crewe if you need the bits Ian Edit i see the problems sorted..
