Wortham blake fisher boy mk3 gearbox flange removal

[RLWP]

Whatever...

[johnny nosh]

Richard, Mike is right

I have already had the nut off

 

I put the gearbox in gear ( forward ) and undid the nut

 

I just have to contort myself into some sort of unusual yoga

postition to find the woodruff key ! !

 

Thanks Richard for the air concern

[RLWP]

In which case, use a lever or a hammer to drive the flange off. It is on a straight shaft with a Woodruff key like this:

It's not an 'Air of concern', I'm trying to help you avoid unnecessary work, What I described is pretty much my day job

I think getting the flange off has turned into a mission, whether necessary or not!

[johnny nosh]

OOOOH Chaps

One at a time ! !

Thats how I almost upset all you kind gents last time

My puter is steam driven, and my typing skills are on the same level !

 

I would love to find a simple way of doing this job, helicoil sonds so good

BUT I have lost 3 yes 3 drill bits into this bolt, titainium drill bits, so drilling

is no longer an option

 

The flange has come off ! !

[johnny nosh]

Mike you are right

Even though you think I am a lager swilling

lout who enjoys footbawll ( I dont by the way )

the flange has to come off ! !

By the way where I come from if you like footbawll

you are considdered rather limp wristed and have a taste for

music by soft cell and boy george.

 

Rugby league is the only sport my town and me are interested in

and I dont live in wigan ! ! !

Richard

Thanks again

I wish you where up our neck of the woods ( meaning I wish you where near to )

I would give you the job and pay greatfully but you are not

 

I am greatful for the pictures and your expert knowledge

but the flange has to come off

Tracy Tools usually stock left hand drills and taps. Regards, HughC.

It shouldn't be massively tight (yeah, right), I would try levering it off first. A mooring spike is a handy lever for this kind of job

IT`S OFF ! ! !

I have done it ! ! !

I used a cut down bolt and a wheel nut from a 1974

Hillman hunter gls ( the one with twin dc0e40 webbers and a holbay engine )

to spread the extraction force evenly.

I put the cut down bolt between the output shaft and the prop shaft, placed

bolts though the prop shaft flange into the output flange and tightend.

 

Nothing happened for a while, then CLICK the output flange started to move.

 

It took a while but the flange came out ! Leaving the woodruff key in the

output shaft and no great GUSH of gearbox oil.

 

Now all I have to do is get the sheered bolt drilled out and retapped ! ! !

 

Thanks again for the hints and tips and the info.

 

I`ll update you all with my progress

All the best

Good work!

Hello all

As promised, here is an update.

The flange came off, had the old bolt drilled out

and re fitted the flange and all the other gubbins.

 

I let her idle for 20 mins then took her out for  a little

trip down and back along the cut for about an hour

and she did`nt fall apart ! ! !

 

Time was getting on, so the plan this weekend is to

just tweek everything up and take her out again.

 

Thanks once again for all the helpful tips and

general banter.

 

All the best
