[Healeys] Timing chain tensioner

[Michael Oritt]

Gordy--

Most of this post is somewhat off-topic as I have a 100, so if you
don't care to read it stop now and just be glad you have a six.  For other
100 owners, or those who want to feel somewhat grateful and/or
superior--read on.

Because there are no springs, etc, between the chain and tensioner on a 100
the task is a tough one.  The chain--with rubber tensioner belt, and two
chain sprockets in place and slip over the two shafts--while everything is
in situ and the keyways aligned.  I don't know how much "assembly slack"
exists--probably a couple of eye lashes' worth--but everything is "offered
up" to the shafts and the two gears--with keyways correctly situated--are
gradually driven onto the shafts until seated. Easy to say but difficult to
do.

I did this alone with engine in place and though a second set of hands
would have helped to keep things aligned and assembled during the process
there is not a lot of room for two bodies in front of the engine--though it
would have been nice to have had a "helper" there to swear and blame
everything on. I don't remember how many attempts it took to get
everything started--several as I recall--but once the sprockets are started
it is just a matter of driving them down the ends of the shafts and into
place.  I do not drink but if I did I would certainly have rewarded myself
with mere beer on the job's completion.

Luckily this operation is not one which must be done frequently.  I'm
guessing I had 75K miles on the engine since the previous rebuild where
this definitely would have been done. Doing this on a bench would certainly
have made things much easier, but it still a difficult job.

Good luck!
