DeDion Wheel Bearing Removal

[MD]

Not a common job but ultimately the rear wheel bearings in the DeDion require replacement as is the case in one of our cars. Apart from the use of a massive slide hammer, does anybody have a better technique and/or developed a puller tool to remove and reinstall these double race bearings?
An allied job is the removal of the bearing lock ring which also uses a special tool. Any tips of a do-it-yourself tool combo is appreciated.

a bid slide hammer and lots of break-out space!

Hahaaa. 

Been there done that.

Actually what I am looking for is a bearing puller that I can couple up to a rattle gun and save some pain.

Just found an excellent write up on the tools and procedures here:

Thanks for those links MD. Every thread I've read on this job has scared me off.

AWWH 'common Al. Don't let me suffer on my own. Where's that true grit Al Campbell we all know and love? 

I am going to make a start of some kind next week. Either beg borrow or make the tools but I never give up until it's time to put a match to it.

Go get 'em MD . Just remember to take your Go Pro & note book for us faint hearted back in the cheap seats who are still paying attention . Are you going to camber the de dion while its out???

[MD]

Hey Gully,
Reset camber ??!! 
Nah. The missuss can't even drop a wheelie in the shopping centre car park let alone give it howl on the track. You see, this job is for transaxle tragics  like me who will even repair a 75 automatic just to keep 'em on the road. It's her shopping basket.
Consistent with my style of posting, if ask a question, I figure others might need the same answer. So if in my research I find an answer, I am not too humble to answer my own question to keep this info circulating.
To answer your question, I will be more than happy to document parts of what may be different in my approach as the procedure is already well documented in the links that I have provided.
My race car does have the modified rear camber but to be accurate, this job needs to be done on the wheel aligner. Using a bricklayer's spirit level is not the go...

Planning to replace the front wheel bearings on the weekend - on the Yamaha. I think a couple of taps with a brass rod should do it. But if they put up a fight I'm ready to step up.

Some more installments on my way to the Chiropractor...

Two left and right hand thread  Alfetta type lock rings to keep the bearing in place. The bearing itself with the PFI (USA) part numbers typed and the FAG numbers hand written lower down. The bearing size is 75mm OD 42mm ID and 37mm wide.

Can someone lend me a sanity gauge please..

Hey MD, I'd lend you my sanity gauge but the scale doesn't cover replacing DeDion bearings. It ends just after giubo replacements.

Hi Steve. I see you are half baked yourself Buddy. Never mind, Uncle Phil will buy us all a lolly at Alfesta. 

...meanwhile back at the Dude Ranch.
Here's an off the shelf tool set destined for glory and become the DeDion bearing puller kit. Stay glued for the modification to make it work.

Gully, don't worry about taking notes mate, there will be handouts later.

1 19x200mm high tensile bolt with nut & washer.
2 Cut down 3/4 inch drive X 13/4 inch el cheapo socket to form a push plate
3 A 2/12 inch X 3/4 inch drive socket also el cheapo with shortened drive connection and internals removed to allow a 78mm cavity room to receive bearing during removal.
4 The actual bearing.
It's kind of weird but while I was selecting the cheap sockets, it seemed that the imperial OD's were a much closer tolerance for my needs than the metric versions of the same thing.

Still awake down the back of the classroom.

Just made me remember a famous quote from my form 5 maths teacher  " Go to the top of the class , but don't take your books as you won't be there long"

Here is one version of the home made bearing lock ring removal tool. It uses a 3/4"drive 13/4" socket (60mm OD) as a basis to weld on some cut down tool steel sprockets made from a 6mm cheap spanner.
