The current clutch slave is about to pop, the mechanism for moving the clutch in and out appear to be overly stressing the hydraulic components.
As I’ll need to take the gearbox off anyway so it seemed like a good time for an upgrade. Apparently the ZF 6 speed from the E46 320d is a straight fit and as a bonus the same angle as the M20, it’s also a more solidly built and younger than the getrag that’s in there now. Only down side is that I might need a different final drive ratio to make full use of the new ratios.
One eBay special later:
But the shift linkage at the top was smashed in transit 🙁
So decided to try and fit it using HTS 2000 brazing rods. I tired this with propane but it wasn’t hot enough. I instead got a can MAPP gas and a new burner from B&Q:
Braced with a bolt and a custom cut piece of rod
Seems pretty solid, will see how long it lasts!
