Can you give me very accurate measurements of the O.D. of the drive flats and the O.D. of the round section of the collar.

Thanks

Do you have to machine the crank much to fit these?

I don't have a micrometer but with a vernier I get 43.7mm and 40.7mm( I have contacted the manufacturer for confirmation. These have sold for years in NZ but I have just started offering them on Ebay.com.au and SAU)

No they are not. These collars are the same dimensions as the Jun collars and have been used with all kinds of pumps. Reimax do not say their gears are not suitable for the standard crank or crank collar. It is possible that they are made to a different cold tolerance because of the type and mass of the materials from which they are made but when hot will be correct.

Your machinist should know how to obtain an interference fit but the guidelines are 0.05-0.10mm interference fit.
