I have a bunch of 83mm liners pulled from various blocks that I have
torn down. Once I bored some out to 89 mm, but the walls were way
too thin and never used them. Joe(B)

Interesting stuff. Though I suspect most of the cylinders laying
around
available for remanufacture are the spun cast ones. I know I have
boxes
of them and I don't think there's a single OEM one in the bunch.

Subject: [FOT] TR3/TR4 Cylinder Liners-Remanufacturing
FOT,
In an earlier life, I spent a lot of time in "Department 62". This was
wet sleeve cylinder liner machining for tractor engines. It certainly
doesnt make me an expert, but I have a fascination with cylinder
liners
that carries over from this experience, to our Triumphs.
I have been playing around with "reman" liners for a couple of
years...in short segments of time, usually during the winter months.
I have used nothing but remanufactured liners....however, to get what
I
want and in the quality perceived, it takes a great deal of time to
get
the desired results. Then you unclamp the part and put it the engine
and
now how does it change?
This is using a good cylinder block and a torque plate for machining
and
honing.
What is the next step? We are meeting with a tool and die shop to
develop a HOLDING FIXTURE that will do the same things as a OEM
cylinder
liner manufacturer.
I have access to some very sophisticated processes on the
manufacturing
side and engine engineers, not more than 15 minutes away.
If we are successful at developing the manufacturing processes needed
we
might be able to provide liners to street and regular Vintage Racing
folks, and do it at reasonable prices.
Sidebar: We are getting some indications, in machining
characteristics,
that the OEM materials may be superior to current spun castings that
come from various sources.
Just thought I would share this....and solict any further insights
anyone might have.
This list could use a little more technical discussion. It has been a
little quiet in that area.

Joe A
