Hi all,
I have inherited from my late grandfather a selection of stuff. In
amongst the stuff is a mystery crankshaft, still in its protective
wrapping from when he ran the garage on Bowes Moor in the 50's and
60's. The tag on it says Austin 5HP STD, £15-6-6, £6-6-6 Exchange, and
the address of the garage. It has 3 mains and 4 cylinders, one end is
stepped, the other end has a flange with 4 holes in it. I cannot see
if its part of the crank, or a seperate piece, as its covered. on the
web near the flange end is a cast in number, 1746, with maybe an L in
front.
I would measure the journels, but it seems a shame to remove the
protective cloth (?) wrapping.

Does anyone know or have any idea what this might fit? I suspect its
austin seven, but they werent 5hp...
dimensions of bore and mains spacing can be taken, if its of help.

thanks

Dave

I'd guess the 5HP is a red herring - just a bit of a part number, etc.
Most likely for an A or B series, if it's something he kept in stock from
the 50s/60s.

I don't actually know the answers to your questions, but I don't advise
taking off the protective wrapping unless you absolutely have to. Once you
let the damp air in, you will never get it out again.

The stepped end would be the crankshaft pulley end; the four holes would be
where the flywheel mounts. The price suggests a relatively early date.. I
would guess that this could be A30, A35 or perhaps A55.

Have you tried asking the Owners Club? There might be someone there who can
positively identify it.

Ive not tried an owners club yet, as I didnt really know which owners
club to contact.
Im pretty sure its not an A Series crank (Im a mini owner), they have
taper flywheel mounts.
Ill take some measurements with a ruler tonight to see if I can figure
out bore spacings.
Is there a 'generic' austin owners club?

thanks

Only on transverse installations. Morris Minors etc have flanges just as
you describe.

Thats a mini crank with the taper for the clutch east west motor - the a
series A do have a flange for the flywheel/clutch mount.

Could even be an old side valve crank if its that old.

Ive learnt something then. I assumed all a series fitments had the
same crankshaft.
Do the longitudinal engines have 'skinny' cranks, ie no balance webs/
weights?
Ill have a look in Vizards TBASE tonight, but iirc that mostly deals
with the mini engine...

A few dimensions might help.

Overall length for a start, and some idea of the stroke, which you should be
able to give us without unwrapping it too much.

Was just in the garage doing that...
All measurements with a ruler, so reasonably accurate, but not
precise.
Cranks is ~17" oa length. stroke is ~3.5", give or take a smidge.
Mains are ~1.75" dia, 1 3/32 wide. big ends are ~1.5"
The cylinders are on centers of: 1 and 2 ~2 9/16" 2 and 3 ~3 and 9/16
and 3 and 4 ~2 9/16" the extra inch is in the center main, not thicker
webs.
The center web has no extra past the main bearing,neither do the mains
at the ends. Ive not seen a crank like that before, usually there is
some balancing web. In Vizards TBASE the photo of the A30 crank (pg
359 in the second edition) looks similar, but the webs between 1 and 2
and 3 and 4 are to thick, and there are balancing weights, whih are
not present on the mystery item. This itself suggests to me it is a
crank for an earlier engine?
The measurements are a bit approx as ther wrapping is in the way,
otherwise Id have used the micrometer etc.

The old Morris Minor side valve 918cc motors had a 3.5" stroke. That
motor was from a Morris series which started in about 1935? and
continued till the OHV Minors were introduced in 1953. There could have
been what they classified as a Morris 8 (8hp) Morris being 800cc motor (
or could this writing be 8 HP not the 5 HP) something to do with road
tax of the time. This would make sense.


I would rule out the OHV A series motor. A series OHV motors were from
2.7" to 3.3" stroke the 3.3" is a 1275.

most mains are 1.75" the journals are 1.625" stroke 3" on a A series
948 CC engine there are no flanges on the crank for counter balance.

The conrod bigends are offset on the rod so the pistons line up in the bore.


The center web has no extra past the main bearing,neither do the mains
at the ends. Ive not seen a crank like that before, usually there is
some balancing web. In Vizards TBASE the photo of the A30 crank (pg
