The car is a Jensen, with the 440 and A727 gearbox. (Both standard)
I've got a problem and I don't know what to do next.
My old original starter was on its last legs, so I got a new one from the
chap on e-bay.
It looks like this:

I fitted it this afternoon and when I turned the key it just made a nasty
noise with no cranking. I pulled it off again and checked it up against
the
old one and all the dimensions looked OK - 10 tooth pinions correct
diameter
etc and it spun up on the bench just fine. I replaced it and tried again,
still no luck.
After some serious head scratching I removed the tin shield from the
bottom
of the bellhousing so I could see the pinion, and with the wife turning
the
key I could see the pinion move up to the ring gear and rotate but not
engage - I could even push a screwdriver up behind the pinion and (with
the
power off) try and engage it manually, all I could manage was about 1/10th
inch of engagement at best. The ring gear is in OK condition and I rotated
the engine a bit by hand so that a perfect segment of ring gear was
presented to the pinion. The starter motor is sitting squarely on the
housing.
So, off with the starter (again!) and I checked pinion throw with the old
Chrysler starter. Here's the crux of the matter I think, the new item has
only 1/2" of pinion throw, while the Chrysler one has 3/4". The
lightweight
starter's pinion is almost fully out and spinning before it tries to
engage
with the ring gear, and therefore doesn't manage it.
I'm at a loss as to what to do. Has anyone experienced this problem
before?
Nobody in the Jensen club seems to have had any bother with these starters
before
TIA Julian.
