Harold- I would purchase replacement springs from Overdrive Spares in =
UK. It appears that you would want to get 4 new short springs (the're =
tired), and if all 4 long look equally correct you could re-use them. =
The importance being that together they "equally" put pressure on the =
clutch lining to keep the car in direct drive (without slipping).  Be =
sure to put the shorts (inner) and long (outer) in properly or they will =
coil bind and really not work well.

=20

I don't know the spring rates, but if you get them from OD Spares, they =
will be the right ones for the job. Be sure to give them the overdrive =
number on the casing for reference to get the correct set. Moss has them =
as well as AH Spares, but did they come from OD Spares, or made in ...?  =

Subject: [Healeys] Overdrive Clutch Springs

I am rebuilding a 22/3087 Overdrive from a BJ7. What should the free =
length of the clutch springs be? All 8 are made from 0.095=E2=80=9D =
diameter wire. The long springs measure 4-7/16=E2=80=9D to =
4-15/32=E2=80=9D and the short springs are 4-1/16=E2=80=9D to =
4-1/8=E2=80=9D. The manual states the springs should be 4-1/2=E2=80=9D =
and 4-1/4=E2=80=9D. I was surprised the short springs are more =
undersized than the long springs.

=20

I saw some mention that the clutch springs in earlier OD models were =
made from two different wire sizes. Does anyone know the wire diameter =
of length of new springs from a reputable supplier?

=20

Thanks=E2=80=A6 Harold
