Just picked a gearbox casing to use for the Spada rebuild and it has a nearly stripped drain plug thread question is its M20 x 1.5 are the filler and drain same size and are they the same on bevel box and sump as if so will need to get a kit to repair them

Not sure about the thread sizes but I have a great selection of gearbox gaskets, O rings etc left over from when I rebuilt my gearbox. Mark at Rockingham ordered them for me and Guzzi sent packets of 10 for most parts, I only used one of each so have 9 spares!

Drain and LEVEL plugs are the exact same on both bevel & g/box, the filler plugs are identical and the same as both dipstick (filler) and drain of engine sump. Pretty sure that’s right as I seem to remember the standard sump drain is identical to g/box & bevel fillers, complete down to the magnetic insert bit, but as I have the Allen key type filler plugs (with O-ring) on the transmission I can’t double-check this. NB: on a previous bevel casing I did get the drain & level threads repaired by inserts rather than helicoil (not enough metal). That was by Gard Auto, Rayleigh Essex). HTH

Going to get a Time-sert sump kit they are the solid insert type much better than helicoils especially on filler plugs etc as they often unscrew the insert with the plug, i alway use them on the spark plugs as well

I sem to recall there are one or two expensive bearings in the box. you might be better getting them on your account ay leicester Bearings. I think Guzziology lists the references you need.
Have a look at one of the needle roller bearings that is unrestrained in the end casing? (from memory). It has a habit of walking out of its hole
