Thread: New Series 1 project

Hi
you can get
or I have them
they are about 1/2 a mm over size
this takes up the wear in the throttle body
it is strange the shaft wears, the body does not to the same amount
cheers

Definitely keen to get through you if you are offering! How much are you asking?
Yes I thought it strange too, they must have used a fairly soft brass to ensure it wears first.

Hi
I can buy them local
would have to ask for the current price
cheers

In a gritty environment with only a little movement (heat not a problem) and especially in a vibrating environment, wear tends to be on the harder item because grit embeds in the softer material. I have had two specific examples of this on my 110 - firstly a brake line rubbed through where the nylon fuel line touched it, secondly, an airconditioner pipe rubbed through where the starter cable touched it. In neither case did the softer material show significant wear.

The material used for the shaft will have been chosen for machinability, and the body material for its performance when die casting. I would be very surprised if any thought was given to the effects of wear.

That'd be good, I haven't been able to find an Australian source.
Dunsfold do them, and the carburettor hospital - both O/S.
Thanks.

Yes dirt and probably oxidisation from the body metal.

Hi Ashhhh
been on to my supplier here in Adelaide
he has standard 5/16", 8.1mm first oversize, and 21/64 oversize about $14 ea.
I have found the first oversize usually takes up any slop in the throttle body
if the wear is greater you will need to run a 21/64 ream or new drill bit very carefully from one side to the other of the T.B.
if you want the shaft send me a PM with your details
cheers
Ian

Thanks mate, PM sent.
