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

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)

Ok, these are too dmall to use with Reimax gears.

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.

      How dare you sell your unreliable Skyline and buy a reliable, Toyota/Yamaha car with a strong gearbox, torsen LSD and Toyota reliability. At least you won't need to worry about oil pumps, big catch can, oil restrictors, blowing off power steering belts, sheering off 3rd gear, failing ABS relays/pumps, etc.

      Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

      Leak from Tokico BM50 Brake Master Cylinder

      The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/
