Re:
Update,
Still waiting for new bearings etc.
Because of the difficulty in finding a suitable spanner I decided to make a tool for use with the two pin adjustable cup. Its not the prettiest but I found an old plug socket spanner and ground it down to leave two pins which works just fine...
Re:
What a day!
Having given up trying to source a specific tool I opted to go with some of the suggestions here and set about with various punches and a hammer. After getting nowhere fast and having hit my hand a few times I went for the bigger 4lb club hammer.
Well, it was not going to...
Oh yes, that is the main reason for removal, there is probably +/- 2-3mm of movement on the crankset and a horrible clicking sound.
Many thanks for everyone pitching in.
I just looked at the Park Tool FR2C which has pins at 25mm and would probably fit but if it isn't designed for the stresses...
Just out of curiosity what are the main factors that determine whether a long cage or short cage derailleur is fitted. The reason for the question is that both my bikes have 14/28 rear clusters but the one with the short cage Huret has 54/42 chainrings and the one with the long cage Suntour has...
Re:
The chain sets both have Sakae dust caps and Silstar crank arms. The 79 has 54; 42 chainrings and the 83 has 50; 36 not that that's particularly relevant but raises another question for another post!
I have gingerly tried tapping with a punch and hammer and nothing seems to want to give so...
Re:
Thank you, I guess it is going to come down to that.
It does seem a bit odd though that these were mass produced fittings 40 years ago and one would have thought a specific tool existed?
Should have added that whilst it appears that the HCW 11 is an appropriate tool it would be nice to hear from someone that has actually removed this fitting before.
Re:
Thanks for that. The spanner you show is the HCW 11 and would seem to be the necessary tool for these slots; I don't know why I didn't notice that :roll: Ideally however, I would want the prongs mated with the 36mm box end of the HCW 4 wrench then I would have both sides covered but I guess...
I am trying to overhaul my crank bearings but on the adjustable side I cannot seem to find a tool that fits the two square slots. There are many 2 pin spanners around but the Park tool pins are 29mm apart and therefore too wide. Also, being square slots and not holes I cannot see how a 2 pin...
Hi I'm Graham and came across this forum while searching for some information.
I still have and enjoy my 1979 Claud Butler that I purchased new from Cooks in Brighton. It cost me £180 and in those days it mean't a bank loan for 3 months.
Is there a protocol on this forum? If a discussion...
