Ilford CAP 40 RA-4 conversion

[smng]

Hi all, I'm following the instructions for RA-4 conversion of an Ilford CAP40 paper processor as seen here https://justinrichards.xyz/blog/ilford-cap40-mod/
First hurdle comes at this instruction "Use an allen wrench to loosen the set screw on the drive pulley, and remove the pulley from the gearbox."
Problem: there is no set screw on the drive pulley. Any other magic workarounds besides yanking it off with brute force?

I'm not familiar with this machine, but have done similar conversions on the RCP20. On these machines, the pulleys are simply pressed onto the drive rod. They are removed with a small pulley puller tool. So basically by force - but ensure that it's applied judiciously...

(Oh, just noticed it's you - I hope the move went well and you settled comfortably in your new home! So sorry I never made it to Amsterdam when you were there...entirely my fault!)

If the pulley and the shaft are both metal, you can apply heat to the pulley to make it expand before trying to get it off. The key to removing such things is to make sure you do it as straight as possible. So don't pry from one side.

There was more than one version of the Cap-40, though I don't know if this part was different

Automotive stores like Harbor Freight sell pulley remover/installer kits. Some auto supply places will loan tools (usually to install a part you have purchased)

This is your first challenge, you'll be fine

I know through a different channel that @smng managed to separate the pulley from the shaft. She used a pulley puller and the thing came off nicely in one piece.

Yeah, those are the kinds of places to look, although automotive pulley pullers are often too big for this particular task. There are very small ones as well; look for those.

I used a baby version of this on my RCP-20 Worked well
