Keith, that's interesting. All the MSA NPR slaves I have seen are bigger than a 25mm bore (30mm from memory).Quote:

Hey Sheldon. You are supposed to be on holiday. You reading this too.
Got up early and put the Disco slave on. Bled the thing for ages, no bubbles but still no go . Only getting 25mm of throw same as the 25mm slave. The 30mm slave would only be less throw would it not
Then got a bit of crap in my eye from under the truck and cant see for tears. Waisted day. These NPR slaves I got are only 25mm. I wonder if I have the wrong master. What should its bore be?
Have a good one.
Keith
Thanks. Its a straight run. The master is on the chassis rail at the front. The slave level with the rail at the back. 1400 mm of straight steel pipe between. Frustrating so giving it a spell while I fit the Tbox and shafts.Quote:

We could always just make a slave to suit.
Thing is I am working in the dark here not knowing how much movement I should have. Any one with a MSA that can tell me?
I imagine the ratio is about 3 to 1 so 24mm at the slave gives 8mm at the throwout. Is that enough?.
I am getting graunching selecting gears but am wondering if it is because I have no Tbox on yet or wheels on the ground to give drag and stop the gears spinning.
Perhaps when all is connected up it will be better.
Yea clutch will still transmit drive with no drag on the other end as it still has light friction, maybe try lock the output of the gearbag to see of it helps, hard to tell from a description unfortunately, shame to fully reassemble only to have to split it yet againQuote:

The pivot is not really adjustable but the slave rod is. I can screw it out to put pressure on the throwout if need be. I dont think the throwout bearing is supposed to be spinning all the time.Quote:

Put the innards in the Tbox and hooked up the driveshafts. Still wont select properly. Start it in gear, depress clutch , it will stop. Start in neutral it wont throwout enough to engage.
Looked up specs Master 19.05mm diam 35mm stroke
Slave 25.4 mm diam 20 mm stroke.
Even with the Disco slave of 22mm bore its not getting enough and thats with the rod screwed up so the bearing is in contact all the time.
Flywheel runout was negligible so cant think of much else to do except find a bigger master.
Any Ideas anyone?
It may be possible to have the D1 cylinder sleeved with stainless steel, if it needs to go to 19mm so be it. Machining down/replacing the piston shouldn't pose any difficulties. I once had a 19mm cylinder sleeved to 16mm to get travel for a conversion. Made a brass piston for it.
Also check your master cylinder has its full travel available, you may have to raise the pedal rest stop and readjust the push rod.
