Does anyone know what the thread is on the drum and cutting blade. I have been to many bolts places and they cannot work it out. I was told it was a BSF thread, but not right.
G'day
Willo and
NormWell, nuts and bolts places you have visited cannot be very good.
The Greens would not have used Villiers proprietary threads at this time.
In fact, the question regards chassis threads, not Villiers proprietary threads.
At this time, Greens were probably using a combo of threads.
In my experience, English used a combo of BSF, Whitworth, and SAE threads
at this time.
In the modern era, the solution will be BSF, SAE UNF, or SAE UNC.
The exception will be 1/2 inch threads which might be Whitworth or UNC.
This is not rocket science, but many 'bolt places' have no idea.
Unfortunately, I have never secured a parts list for a Greens Master.
If this issue causes your grief, PM me and we will work through this.
We are here to help each other.
