hour tops. bench bleed the master first. if you're replacing them on the 240, get the damper loop removed and get a stainless "damper loop removed" clutch line. It'll save you alot of time on the bleeding.

if you have a look under your hood, you'll see the clutch master cylinder. follow the hardline to the transmission. you'll see some weird box thing that it hooks up to. from that box, you'll see a loop and then it'll run to the clutch slave cylinder. If you check out splparts.com you can find the new clutch line that will eliminate the box and loop. That is a problem area even for experienced mechanics since air loves to get trapped in that box from hell. So now you should have only a clutch master, hard line, stainless steel clutch line, and clutch slave cylinder. open up the clutch slave cylinder and pour some brake fluid into the clutch master cylinder's reservoir, it'll take a little bit to trickle down to the slave cylinder but when you see fluid start to ooze out, close the slave and top off the master. pump the pedal a few times and hold while someone opens the clutch slave cylinder's bleeder and let all that air infested hydraulic fluid squirt out. Close the bleeder and repeat. Don't let the fluid level fall below min on the reservoir. repeat till the fluid that comes out the slave cylinder is air bubble free and clear.
