dead easy
1 undo the battery cables, and (optional) drain the box
2 whip the tailshaft out, if you didnt drain the box put a bung where the tailshaft goes into the back of the gearbox to stop the oil leaking.
3 support the motor with a jack
4 undo the speedo drive and reverse light switch wiring
5 back the clutch cable adjustment off to release the pressure on the clutch fork. the two 17mm nuts on the clutch cable at the firewall.
6 whip out the starter motor
7 undo the bellhousing bolts from up the top that you can get to.
8 support box with jack and unbolt mount and remaining bellhousing bolts.
9 evenly remove clutch pressure plate bolts in a hexagonal pattern so as not to bend the pressure plate.
10 remove clutch and then flywheel, get flywheel machined. note you must do this or otherwise problems will come out later on down the track.
EDIT: lube the gearbox points of contact for the clutch fork assembly and also replace the spigot bearing, this insures that you wont get a mad noise down the track when its siezed in the end od the crank lol
11 repeat steps using correct torque settings on the flywheel bolts (use loctite too) and also importantly the clutch plate alignment and the way you do up the pressure plate bolts. do them up in a hexagonal pattern at quarter of a ratchet turn each, doesnt sound like much but you can bend the pressure plate and damage the assembly if you dont do this properly.
if in doubt get somebody to help you.
cheers kurt

minor detail pigdog lol, angle grinder takes care of that.
so ok before you undo any of the bolts under the car, undo the circlip that hold on the gearstick and remove the gearstick.
there will always be something i would forget to write down lol

Easy as mate The boxes weigh next to nothing which helps to. If you have a manual follow the instructions if not there is probably a manual on here somewhere.

unless its my car and it all sits at least 20mm higher than its supposed to then just whip it all out and do an engine conversion just for the sake of a new tunnel

would be quicker ay piggy

Hmmm seems like too much for me. Id get it jacked up, engine supported, gear stik out and g box out, but thats all i could probably do.. I might need some help.. I thought id try it, everywhere i called today quoted $160+, all i needed was labour, ive already got the clutch. Didnt think it took that long.

Haha im pretty happy with the A series right now!! Conversion for later!

Get yourself a Gregories service & repair manual for a Datsun 1200 [try eBay] they are cheap & are writen for the home maintainer.
They have lots of photos showing how things are done & should be one of the first things you buy whenever you get another car. They will save you a lot more than their purchase price with the first screw-up that you DON'T make as a result of reading it twice & fixing it once.

For what it's worth, I've been a mechanic all my adult life & I have a book case full of Datsun manuals. Real mechanics DO read the manual when necessary despite what some backyarders might tell you.

As Dodgy said,theres nothing wrong with"how to manuals"cause nobody is infallable.As well as buying one you might consider jacking it up and getting it on stands(nice and high)then calling a mobile mechanic and asking him if you can be his second man...cause you want to learn for future referance how to change a clutch.

$160.00 is only about 2 hours work which is reasonable if in doulbt,it's worth a try.
