What about trying a mini hammer impact driver? (small version of the original type) like this: https://www.louis-moto.co.uk/en/mini-impact-driver-set-7-piece-chromed-10002580?partner=googlesea-uk&cpkey=jqz0L3SMyo-B8GYqQ8TL7fx8sYHObdEBxBpU2KX4nJHuziyMJdQLYNIAT7aU63MyWsaRKGiZkPovzza5G4iTuA%7E%7E&gclid=CjwKCAjw2K6lBhBXEiwA5RjtCXgLNumA4X71e0KiwNZeNHQ7sk-TTRB5xvIedCji1xtnZWZu7dyIrhoC3x4QAvD_BwE&filter_article_number=10002580
I have that tool...it's very unclear which way is which, but if you use it on a fastener that isn't tight, and just give it a little tap, then you can see which way it turns it for the L or R setting.Nb - do you need to remove the windings to polish the case? If it ain't broke etc...
All my JIS tools are also marked with a PH number as well - all academic now as I have undone the lot.Following Matt's idea I read some online instructions - put my Big Boy work gloves on - found my second biggest lump hammer then gave the outer screws some serious percussion - all came loose in under two minutes.As I was undoing the inside screws my tool fell apart - I found the balls & cups put it back together re-fitting the circlip - last two came undone but not before the tool came apart again. Needs a new circlip I guess.I'm now knackered - enough for today - time for a beer!
Always better to tackle the problem now Ted rather than wait until it really becomes a problem. It would also be easy to damage the windings accidentally if you'd left it in to polish, the weight would have made polishing it harder IMO. When inserting the drive bit twist the tool to preload the bit so when you hit it the drive will move immediately. You can buy JIS bits to fit that impact driver.
PH3 is Phillip's, not JIS
