Clutch help on RA28

G'day all, I just brought home my RA28 with a 18rgu, got it for $800, has a few good points and a few bad ones, but overall i'm pretty happy with it. One of the bad points is that there is no drive to the rearwheels (or the tailshaft for that matter) and I was told it needs a new clutch. Having never changed a clutch before, and only having owned front wheel drive cars prior to this one, I was wondering if anyone could give us a run through of what to do, and any tips/tools that will make the job easier?

get the car on stands
2x12mm spanners take off the the nuts and bolts attaching the tailshaft to the diff
then take out the 2 bolts holding the tailshaft center bearing
u can now take the tailshaft out but if u havent drained the oil in the box then leave it in for the time being
take out speedo cable from gearbox
disconnect the slave cylinder
get the longest socket extension bar possible one of those 3 - 4 foot ones and stick a stiff socket uni joint attachment on it (if the uni joint keeps flopping around a little electrical tape can help)
take out all the bellhousing bolts bar 2 either side that are easy to get to. then get the trolley jack under the box and take out the gearbox xmember and left over bellhousing bolts, lowering the gearbox onto the ground with the trolley jack.
take the pressure plate off the flywheel and wala.
P.S i typed this up rather quick so if ive missed something someone add it in

Yep, it's easy.
1. if you're not mechanically minded, don't try it! Take it to a workshop and have them do it!
2. if you don't have a good tool set, jack, axle stands, and a few mates, don't try it!
3. if you don't have a hoist or a pit, I advise you not to try it!
4. disconnect battery, jack up car and support front with axle stands.
5. drain oil from gearbox (cos you will spill it everywhere!), remove tailshaft, speedo cable, shifter, starter motor, clutch slave cylinder and reverse light wires.
6. remove bellhousing bolts except the top two for safety, and the gearbox crossmember and gearbox mount, once the gearbox is supported by a jack where it won't fall off under movement.
7. move the box out and down from the back of the engine, and slide it away from the car once free of motor.
8.remove the six bolts holding the clutch to the flywheel, but don't remove them one by one - rather loosen all first then remove them to avoid breaking bolts in the flywheel.
9. once the clutch is out, check the flywheel, and reface it if necessary (probably will be), and reinstall.
10. loose mount the clutch up, as you will need to position it before tightening up. You can buy clutch aligning tools, or use sight if you don't have one - the centre of the clutch should be centred to the flywheel.
11.tighten the bolts up in the same order and fashion you took them off in.
12. remove the throwout bearing from the fork and press a new bearing on (you'll need a bearing press for this too!).
13. reinstall in the opposing order of removal, and don't forget to fill the box up with oil, or you'll be doing it all again in a short space of time!!!

Pffft! Hoists are for pussies. I must have dropped dozens of gearboxes using nothing but a trolley jack and a couple of jack stands. Yeah it's a PITA to do it that way, but still quite do-able.

Cheers, i'll get a quote for a mobile mechanic to do it, if i supply the clutch. If it seems a bit steep (ie. more than 100) i'll have a go myself. I have the tools and the mechanical knowledge, just sounds pretty involved, especially not having the service manual. Thanks for the help.

It'll seem steeper than that my friend!!! I'll agree with the others, doing the job on the ground is doable, but a major pain in the arse! Personally, I'll stick to the hoist!

clint do u realise that not every toymodder is lucky enuff to have a hoist at home yet we still manage with engine conversions and car stripdowns. Doing a clutch while the car is on chassis stands is not a pain in the arse. You shouldnt dissuade people just cause your too lazy to get onto the floor. 
matt dont be discouraged it really isnt a complicated process at all. otherwise go down to your local parts shop and buy a Haynes celica manual for $20. Or even cheaper hire it from the library!

Just adding to clintgoddes little mini manual you can use a broom handle as an alinging tool as well as sight.
Get a manual and have a go yourself its like lego.
just make sure that when you finish you have no bolts left over!!

Thanks for all the help guys, looks like i'm going to give it a go. Best quote I got was $350 supply and fit, which didn't seem too bad, but i think that extra money would be better spent elsewhere, especially since this would be a good "learning experience". I'll jump stright on here if I have any probs.
Cheers

Just a quick point of clarification for all those who think I'm a hoist snob(   ), I don't have one either, and yes most of my mechanicals are done under high lift 5 tonne axle stands with a creeper! I've tried both ways, and prefer the hoist, I have plenty of friends with hoists so have ready access to one any time. I have met someone who tried to do the changeover on the ground, he spent 18 months recovering from a shoulder reconstruction after dropping the gearbox on his shoulder, he stated it rolled off the jack (personally, I like throwing a baseball around so am not keen on this happening to me!). Your W50 will weigh 40Kgs, be prepared for it!
Have fun with it, it a good learning experience!

She's out, took me and my mate about two hours. The clutch is gone, nothing left of the clutch but black fluff in the bellhousing and a steel plate.  Putting it all back together tomorrow, hopefully without too many snags...everything is always harder to put back together.

Using a skateboard to move the g/box from under the car and back is what I used. Then roll the gearbox onto the jack.
I'm with the boys on this, car jacks are easier in my opinion, do it for the first time it will be so easy on any other occasion. Good on you.
