Greetings from Snowy York,
I've just changed the front discs and pads on my neighbour's Vauxhall
Carlton. I must be mad, doing it in this weather.
However,
I spoke to Mocal today, telling them that their filter thingy leaks. The
helpful bod on the phone admitted that they do soemtimes get a 'problem
block' and offered to machine one of the next batch of adaptors to suit
measurements I send.
Good idea but how could I possibly make accurate measurements with the block
in situ?
So, helpful bod said that they have different thicknesses of outer (square
section) sealing rings and will send me some to try. Good man.
This got the old grey matter ticking so I went to visit my local bearing
supplier, having bought a new paper oil filter c/w new rubber seal. Having
measured this new seal with the man's fancy calipers, we found it was 3.2
mm. thick, front to back.
Now, your standard, nominal 1/8" O-ring (round section) measures 3.5mm-are
you thinking what I'm thinking?
On paper, we get 3/10mm. extra crush on a round section seal which will give
a narrower sealing area. The material is also softer (75Shore rating as
against 90 for the standard seal).
So, armed with this O-ring and the thicker square section seals from Mocal,
I'm going to stop this leak, so there!
Mocal Oil Control is a UK company, a.k.a. Think Engineering. They live at
Isleworth in Middlesex.
Will this idea work? Stay Tuned.
Cheers, Dave Hill
