Trugrip Collet chuck Mods

Re: Trugrip Collet chuck Mods

Thanks Nick.
Despite taking off all visible screws, I can't seem to disassemble further than removing the threaded collar.
I've taken out the ring that I guess retains the rotating part that the collar was screwed to, but that's not budging - I've also taken out the three screws with the long plain ends that I think must retain the pinions, but the pinions themselves are not coming out - but they move a little more now the screws are out though.
Any more pointers? Are things press fits - do I need to use a puller or a press ?
Cheers,
Youra.

Re: Trugrip Collet chuck Mods

Youra,

It's not quite clear from your description whether you've managed to remove the threaded collar. From memory that's as far as I got, or needed to make the change to 5C: I didn't completely dismantle the chuck. That said, pinions are often tight, held in by coagulated grease as much as anything. They will pull out with a bit of persistence once the retaining screws are removed - which it seems you have done. The internals of all chucks are, or should be, pretty tight fits so yes some persuasion may be required, but unless the Crawford is 'back to front', which it might be given the LH collet thread, the pinions need to come out first. I can't recall the rest of the chuck construction and would have to remove mine from its back-plate to remind myself, which I'm reluctant to do. I may come across a another in my travels and will report back if you haven't succeeded by them.

Nick

Re: Trugrip Collet chuck Mods

All sorted :-)
I had managed to get the threaded collar off - it was further on from that, that was a problem.
I eventually managed - by tapping from the front (not *too* hard) to get the pinion ring that the threaded collar was pinned to out, and it's also clear why the pinions themselves wouldn't come out:

I've no intention of taking out the second ring that's preventing the pinions from coming out - I can clean and lubricate perfectly well at this stage.
There's also a sheared anti-rotation pin that should prevent the thrust washer rotating in the body of the chuck to replace, and I'll use the matching hole in the washer to drill a location for a new one.
Thanks everyone for the help!
Youra.
