Shimano 600 Arabesque Rear Mech

[Hanlon]

Hit another issue in rebuilding my late father's Holdsworth Mistral (and hope I don't bore the pants off people in the process !) Need to source some new jockey wheels for the Shimano 600 Arabesque rear mech, and of course in lockdown I can't just saunter into a bike shop and match things up Shimano 105 RD 5700 and RD 6700 look similar - but would be grateful for anyone who knows and just as important, where to get them ! And while you're here, I tried to use my classic screw in Campag crank puller on the TA chainset and it would not go into the threads. Does the TA have a different thread or are the threads just mullered ? All advice gratefully received !

Tacx ones will do the job or basic upto 10 speed shimano ones from 105 upwards.

I think any Shimano-compatible 8 speed 10 tooth wheels should work, including Tacx T4025, T4020 and T4000, which seem easy to find.

Are Campag pullers different? I'd expect TA to take a generic puller. Threads corrode readily, sadly.

The Tacx ones, despite no float that shimano used on later mech jockey's are excellent. Need no looking after other than wiping clean.

Many thanks for the helpful information chaps - no more blundering in the dark on that one now
The Campag puller works fine on every other chainset I've tried - SR Royal, Raleigh, Nervarstar etc - so it looks as if the threads on the TA have given out

I have an older style Stronglight TA crank which has a larger thread size. It's not much larger but enough not to allow the puller to grip .

Campag is 22mm. TA is 23mm. As above you likely need a TA extractor.

Thanks Illaveago & midlife (great IDs BTW!) I Think you've cracked it - this TA is definitely old skool and the threads look fine and the dust caps screw perfectly I managed to get the chainset and cranks off with one of my classic car hub pullers so no damage done Thanks fellas!

Update: Thanks for the advice to get Tacx jockey wheels. Ordered the T4000 type and after some trial and error selecting the correct insert shims they fitted perfectly. There are no lubricating instructions with the wheels - does anyone know please if I should apply oil as with the old Shimano type ?
