Hi Clois,
I am happy that you like the clutch calculations. Sorry that you need to convert to inches, perhaps I need to update the sheet with a tab in inches and lbs.
It would be a day that you guys will change everything to metric.
The last week I was surprised with this fact. I was removing the Melling
oil pump and I did select a inches socket to dismantle the pump cover, at that moment I though this socket doesn’t fit correct. When I did look to the bolt I found that is was metric.
I never did expect this, because my experience is:
Old basic stuff is Inches new technology is metric.
Like the engine block, it is inches, but the injection components are all metric.
So it is time to get crazy.
I hope this sheet will give you the required information, lots of people has used here in Europe and all say that it works very well.
There are some components like friction etc that are not take in account but the influence of those is minimum.
A very important item is the stroke at the slave cylinder, you should have some spare there for the time that the clutch and clutch plate start to get worn, at that time you will need more stroke at the slave cylinder.
