Hey guys,

Ive got this XB falcon here, rite, and the clutch is gone. Like completely gone. Obviously I have to replace it, so ive got a few questions for yous plz

The first1 is, what are the chances that my flywheel needs machining, considering that the clutch has been worn to the pt where its just like there is no clutch there

Second is, ive got a mate who has some experience with clutches, i have none, can we change the clutch ourselves? Ive got the service manual and everything, and i know in general how it all works

Thirdly, in the service manual, for all the falcon models xcpt the xb it says that when removing the transmission you merely need to lift the car up onto stands, but for the xb it says you need to put the whole thing on a hoist? why is this? if i decided to do it myself it would be on wheelstands, not a hoist, so this is why I want to know

Thanks guys

what type of gearbox are you running? toploaders are great big heavy things you'll need a helper, whereas the single rail is fairly light you should have no worries moving it about for removal and installation.
yes you should machine the flywheel if your putting in a new clutch and from the sounds of things it will probably need it anyway if its been that worn out.

there isn't that much to doing the clutch even if your using hand tools.

RevHeadRon,

What is a top loader? the gearbox is a 3spd transmission with synchromesh on on second and top speeds (thats straight out of the service manual) its a colums shift tho. The gearbox looks fairly small-ish. It isn't borg-warner. The service manual doesnt say anything more than that. I dont have much experience with this, so do you think it is safe if we do this with the car on stands (yeah, i will have a helper)? Also, i dont really have any facilities to machine the flywheel - whats the worst that could happen?

Thanks mate

sorry i didn't get back to you sooner, yeah you'll be right on car stands. i would machine the flywheel but its not absolutely necessary.
and the worst that could happen would be maybe a bit of a shudder in the clutch.

ok well ive put the clutch in, and it feels good, aside from one thing. When the clutch engages there is what sounds like a hissing noise coming from the bell housing area, it sort of sounds like a scraping or rubbinng. It only happens when I take off, and doesnt happen when i press the pedal while the car is in neutral. Have i done something wrong? is this throwout bearing noise? or is it just some sort of coating on the clutch disc that wears away after a while?

thanks

Michael

could be your throwout bearing, did you replace it when you had it out, and same for your spigot bearing? did you replace or at least re-grease it?

michaelB123

nah i didnt touch it. What is it? What are the probs that it can cause?

Thanks

i was talking about the spigot bearing btw. Yes i did replace the throwout bearing

The spigot bearing is the bearing that goes in the back of the crank that the end of your gearbox input shaft sits in when together.
There are also two types, the later one (which is probably the one that you have) is an actual bearing that when you take the box out, you normally regrease with your fingure and fill the gap behind the spigot bearing full of grease and obviously the bearings too.
The other is a spigot bush, just a solid bush that sits in the same spot but has no bearings. These were used in the XY and earlier.
Although not a huge problem that you didn't do it, you should put it on your "one day when i have time, because i forgot to do it list"
