Recently came across a rkra711 kit on eBay and noticed it says it works for the 71M along with the 710 line and such. Now I'm confused on the 71M part because I'm assuming it means the No.71-M and the parts, while mostly the same, arent a complete match. Looks like a bushing and the name plate are included which aren't on the No. 71-M and the selector is one piece instead of a brass pin with a steel lever held by the brass being hammered over. I haven't worked on a snap on ratchet with the name plate so I have no idea as to if it'd make any difference being installed on the No. 71-M. Curious if anyone has any experience with No. 71-M and if that kit actually is compatible with an extra piece, maybe mines just stuck but looked like it's part of the body on No. 71-M but assuming it's built in, and an upgraded selector or if there's something I'm missing as far as something else using the 71M code once upon a time.
Snap On No. 71-M rebuild kit

The 71M does not have a name plate, so the wheel would be different, would not be bevel
with the plane of the rat, uses a 24 tooth wheel, the 711 kit has a 32 tooth wheel, The 71M uses a RKRA71 kit, I do not think it is available. The 711 kit would probably work, but the wheel flange would be low.

Thanks Snapmom, figured the same on the differences but was confused at the inclusion of the 71M on the compatible ratchets section on the 711. I would think if the bushing was replaceable on the 71M it would work as an tooth upgrade kit but mine didn't appear to have any gap like you'd see with a removable bushing. Was thinking maybe there was a removable bushing in later 71Ms or something to make the inclusion but haven't seen any evidence of it. Also the 71 kit is discontinued. Can find a few one ebay here and there still though.
Looked around for info on the S71, kinda more modern version, since it's listed on both kits too. Noticed alot of them have the little relief in the back of their drives like the name plate ones cover. Couldn't find anything on if they have a removable bushing but both kits come with one so I'm assuming they probably do and it's in the kit just for the few that might, 71 doesn't come with the plate. Also nothing on tooth count so far, not much out there with older models unless they're very old and highly available. Granted if both kits work then some would be 24 or 32. Thinking the 711 might work fine, S71 doesn't appear to be off with the divot versus without, and of course more teeth and the not so nice looking divot in the back of the drive. Overall I can't see a difference between the two drives in the pictures other than the divot. Plus potentially the 711 might work in the S71 with the name plate which would probably look nice. Think the plate versus no plate would just be the military vs civilian models and kits and probably the 711 being used instead of the 71 kits on later batches as an upgrade minus the plate.
This is the difference between a wheel with a rat with no cover plate and one that does, other than this , the S71 kit should be the same, but if you use the wheel from the s71 kit, it fits, but you will have a gap where the top of the wheel fits in. if you can live with that, then get the kit for the S71 (the newer kits, will have that gap), the older S71 kit would be the same kit as the 71M

Thanks for a better comparison. It's not noticable in the pics of the ratchets I seen but I ended up more confused after finding a rebuild video, 710 upgrade from 24 to 32 with plate, where the no cover parts had a divot and the drive with a name plate didn't. So maybe they all were old kits and for some reason some were divoted in the pics I looked at. I assumed the plate was about the thickness of an aluminum can and was just a thin piece to seal off the back, not removing almost any material from the drive, but I guess I was wrong. I'll be looking out for the 71 kits, looks like they're out of season on ebay right now, but I might get a 711 kit cheap for the spare lever mainly. My 71-M lever has a little give so it'd be the first piece to wear down with use. Might be able to find the code and get the lever on its own too if I look around for it and it's sold on its own still.
Snapmom, I was wondering about the books you have with the diagrams of various tools internals, you posted the ratcheting adapter pages in another of my posts. I recently found the collecting snap on website and was curious if those are somewhere on there. Seems like a copy of them would solve my questions for the most part before I ask on here. Already found the 1938 pamphlet diagram booklet but it doesn't have any of the more common stuff since it's an older collection.

Be careful about the collecting Snap-On website. There is a LOT of misinformation there. Just verify elsewhere any information from there. It has value, but is full of holes.
Main thing on it is the catalogs. Need to gather some functional information like diagrams and parts lists so I can have an idea what I'm doing without going all over around here hunting for part of what I need. Tried checking out the forums but it's more confusing than here so I'm avoiding it. So far I've only found the 1938 parts booklet which is kinda useful but lacks the more refined models. Along with anything modern of course. Wish Snap On left their old diagrams up instead of 86ing everything's existence from their site.
Is it actual booklets from snap on or is it a collection of information you've found? The adapters section is the kinda stuff I'm looking for mainly, a simple design view and a overview of parts. 1938 booklet is the same thing but only the oldest stuff. Would think the drivers would have something like that too but local guy doesn't work on anything at all now and before he only knew the basics and no tricks. Especially with the more finicky stuff that has to be tapped the right way, you could expect it to sit in some acetone for a week or two then come back as it left.
Thanks that might be enough of a lead to finding them online. Going to see if I can find a pdf anywhere then go to support and see if they might be of any help if I don't find anything.
Nothing on Collecting or online that I could find. Google isnt that useful though since there's a thousand different manuals for various snap on electric equipment it brings up regardless of how you phrase it. Went to support and we'll see what they say tomorrow. Meanwhile 1938 booklet and date code sheet will be printed out tomorrow. Plus lamination for date code since it'll be in direct line of fire during any tool maintenance.
Also looks like my adapter does have a bad spring, the written instructions makes it clear compared to the drawing showing two springs which is actually a split view. No kits, even 3rd party, so pen spring will have to do. Once I decide to break it open again of course.
Mines one of the original 67s before the variants. Spring stayed through all the variants though which is kinda surprising considering its brass. IMO it's probably the biggest failure point in it since it's a softer metal. Not sure how much use mine went through since it was bought with a socket set with a ratchet and a shorty breaker bar by my great uncle but the spring is the only piece to show major wear with the two ground off rings leading it to split into two.
They look different than what mine are. Mines brass and around the size of a pen spring. Code from the pages shows ESD-47 as the item code too. Yours look more like a self centering detent spring or something. But maybe they did change design but the two would have to have a bearing or something between them to not lock together eventually. Also received a reply from support, they sent me a page of the various pseudo patent versions of various ratchets, the ratchet whole with parts in x-ray view and noted, from 2001. Kinda like a study sheet for a test to identify the parts.
I'll measure my 67s base and see what it is but the spring should be about the same length as the whole base. Maybe a hair shorter to help line the pins up for reassembly. Estimate would be about 1/2 inch long and if the deburring instructions are the same as the spring it'd be 1/8 diameter.
Heard back from support again. They said they don't have any service parts list booklets. Recommended collecting site too. Looks like it might be a search for people with the different copies that has a way to scan and upload. Also spring is about 1/2 inch in length.
For some reason my reply didn't post but here's the recap. Support replied no booklets are available. Recommended collecting instead. Spring should be around 1/2 long.
Edit:didn't realize it went to two pages.

Hi if you've looked through the replies you'll see the rkra711 is the kit available from snap on, rkr71 if you get lucky and find one 3rd party. Rkra711 will have a recessed drive head on the back of the ratchet though. Haven't popped mine apart again to see how the bushing works but with bushing replaced with the one in rkra711 it should look right with name plate and all. Currently waiting to see on a rkra711 then I might do a fit check and make sure everything lined up proper. Only thing I'm not sure on is the bushing though, everything else should work fine minus the recessed drives cosmetic wise.
Update on rebuild kit rkra711. Was watching one on eBay and it ended up going past retail. Noticed recent auctions have been going over retail on alot of the cheaper stuff for some reason. Was also watching a beat up williams 1/2 36 tooth usa model and it went for same as the new one on Amazon I ordered. So basically waiting on either $200+ order for free shipping or have someone track down a driver for the kit.
