So here's a little more info about the BJ8 engine with the ring gear halfwa=
y on.... or halfway off.....depending on one's perspective. I learned from=
Steve Byers (BJ8 registrar) that the car that had that engine is in Englan=
d as of 1989 (or at least a car that has the body # plate of that car). S=
teve happens to have the British Heritage certificate for that car but no o=
wner info.=20
Because the ring gear was rubbing on the two upper engine plate bolts and m=
aking lots of noise=2C the diagnosis at the time was certainly some kind of=
engine failure=2C and therefore=2C the engine was pulled. This is an engin=
e that has a little over 5=2C000 miles on it.
I have a theory as to how this how this happened. The heads on the bolts a=
re ground down a bit but there is no apparent damage to the ring gear. Obvi=
ously=2C it's a much harder material. The ring gear was up tight against th=
ose bolts heads. This leads me to believe that the engagement of the starte=
r must have pulled the ring gear off its perch and up tight against the bol=
t heads. =20
I have this motor for sale on Cragislist in Portland Oregon. I'm not going =
to fix the ring gear so the new owner of this engine will see what I am tal=
king about and understand why this is such a low mileage 29K motor.

I have found the comments on this topic to be very interesting with regards=
to the heating of the ring gear. I am no metallurgist so I tend to pay att=
ention to manufacturers instructions regarding the heating of metal compone=
nts very carefully.
In the BN1 workshop manual instructions are given for shrink fitting new br=
ass syncro cones onto the gears. The instructions read:=20
"The heating (of the syncro ring) can best be done by immersion in oil of 2=
50 degrees Fahrenheit and then fitting by means of a hand press. After shri=
nking on=2C the unit should be immediately be quenched in water to prevent =
the heat softening the gear itself.
250 degrees Fahrenheit is the equivalent of 121 degrees Centigrade.=20
Well=2C if we are going to be heating the actual RING GEAR to 2 or 300 degr=
ees Centigrade should we not perhaps be a tad concerned about heat softenin=
g the ring gear??
Just a thought....

If you can't fix it with a hammer=2C you've got an electrical problem.
