Bleeder wrench size ? Trans/diff nut size

What size flare wrench is used on the bleeder screw on the 235 caliper?

Also which size socket or bit socket is need to drain if applicable / refill the manual trans and diff ?

And what suction tool do you recommend for siphoning and filling those parts ?

Thanks

not sure on the exact size, but just buy a metric set of hex drain plug sockets, there are 3 sizes total you need for both parts (one for the diff, 2 for the tranny (manual)

I bought a cheap dc powered drain pump of ebay, was like $20, none needed for trans.

have not bled the clutch, but looks like std. brake nipple so prob. 9 or 11 mm.

Then get yourself 2 fresh transfer pumps for the fluid going in, I buy my fluids in gallons so they just screw on and I pump them in till overflow.

Pretty quick when you get the hang of it, prob 45 minute job second time around.

Not sure on clutch bleed, looks like std brake nipple 9 or 11 mm. Keep in mind that is brake fluid so you will need to pressurize or have someone pump the clutch like the bleeding brakes.
