Car Forum / MINI / September 2003Flywheel Nut/Bolt size?
I shouldn't need to ask this but: What size socket/spanner do I need for the nut on the flywheel of a 1978 1275gt? I forgot to buy one before starting to take my engine apart :\ splam BIG > I shouldn't need to ask this but: > [quoted text clipped - 4 lines] > > splam I had the heat up the nut big time when i tryed to get mine off, its not just tight its glued on to the bolt too :( good luck, you will need a BIG hammer too And Rocky was sitting next to Elvis in the spaceship, which I thought was kinda strange, but then they turned to me and said: > I had the heat up the nut big time when i tryed to get mine off, its not > just tight its glued on to the bolt too :( > > good luck, you will need a BIG hammer too Only if you don't mind bending the crank or wrecking the thrust bearings.

Yep - dont hit the back of the flywheel assembly to try and get it off !! You risk cranking the flywheel too! - Any you don't want one of those exploding at high RPMs... TTFN, Dave I use a 3/4 BSW socket not sure what that works out to be in AF but the equivalent in AF will be measured across the flats to give the size. > I shouldn't need to ask this but: > [quoted text clipped - 4 lines] > > splam I use a 3/4 BSW socket not sure what that works out to be in AF but the equivalent in AF will be measured across the flats to give the size. xsplam wrote: > I shouldn't need to ask this but: > [quoted text clipped - 4 lines] > > splam 1 1/2" AF.

It's amazing how hard it is to find a 1.5" af socket on a .5" drive. Of course, you can get metric in 2mm sizes up to 40mm :( grrr > It's amazing how hard it is to find a 1.5" af socket on a .5" drive. > Of course, you can get metric in 2mm sizes up to 40mm :( 1.5" = 38.1mm. >> It's amazing how hard it is to find a 1.5" af socket on a .5" drive. >> Of course, you can get metric in 2mm sizes up to 40mm :( > > 1.5" = 38.1mm. Yup, I did the math for that - .1mm to big for a 38mm socket ( and indesperation I did borrow one and try ). Just remarking on how weird demand driven supply can be.. or annoying perhaps?

Now let me get this correct your saying a socket that is .004" under will not fit the flywheel bolt??? rm ops <martin@w'gong.apana.org.au> wrote in news:3f548671$0$95051$c30e37c6 @lon-reader.news.telstra.net: > Now let me get this correct your saying a socket that is .004" under > will not fit the flywheel bolt???

You can get 1/2" square drive to 3/4" square drive adaptors. John Mackesy "John Mackesy" <mack@melbpc.org.au> wrote in news:bj22kc$fiq$1 @possum.melbpc.org.au: > Sigh. You can get 1/2" square drive to 3/4" square drive adaptors. *Sigh* yourself monkey man - of course you can, that's not the issue. It's just the bolt that holds the flywheel to the crank... it's not quantum physics. > "John Mackesy" <mack@melbpc.org.au> wrote in news:bj22kc$fiq$1 > @possum.melbpc.org.au: > > Sigh.

John is completely right, if you can't find a 1-1/2" AF 1/2" drive socket, and if you can't get a 38mm socket to fit, then a 3/4" drive 1-1/2" AF socket is the obvious solution. > hat is uncalled for. > > John is completely right, if you can't find a 1-1/2" AF 1/2" drive > socket, and if you can't get a 38mm socket to fit, then a 3/4" drive > 1-1/2" AF socket is the obvious solution. Yup, I agree, and at no stage did I say I didn't. John *sigh*ing at me thinking I hadn't thought about getting a 1/2" > 3/4" drive adaptor is what I have issues with - as well as the availability of decently priced 1-1/2" af sockets - ( i.e. not SnapOn's 100$nz+ socket, I just don't need that quality of tool ) I've actually removed flywheels before - you could probably find my posts on groups.google.com - but with borrow tools, hence my original question was only about the socket size. splam > >> 1 1/2" AF.

Even Halfords stock them these days.... or any reasonable Mini parts supplier ;-) SignatureRgds Steve steve@dsnclassics.co.uk www.dsnclassics.co.uk Remember there are 2 thread sizes on the flywheel for the puller legs. I think the change must have been when the A+ was introduced I had to buy a new puller as the one I used back in 1979 didn't fit. The new puller came with both thread types. > I use a 3/4 BSW socket not sure what that works out to be in AF but the > equivalent in AF will be measured across the flats to give the size.
