How to change a TVR Giffith Clutch
Discussion
Hi,
My 1992 Giffith is now slipping its clutch and I think time for some maintenance.
Is there any documentation or manual which could assist with the job. I did find a website address but this appears no longer valid:
http://www.thetvrsite.com/engine/4-engine/16-clutc...
Any assistance would be most welcome. Regards John

That site is more Cerbera focused so might not be too relevant.
The main question is, do you either drop the gearbox and change it or pull out the engine? Either are possible it's a question of what facilities you have.
There's info in the Steve Heath book http://www.tvrbooks.co.uk/ if you haven't got a copy I suggest that would be a good first step. It's probably the nearest thing to a workshop manual.
Also worth checking out http://www.rv8r.co.uk/home.html
There are some Land Rover WS manuals out on the web http://www.landroverresource.com/40_46_V8_overhaul... which might have some useful information

No... I wouldn't use a hoe to change a Griffith clutch. I used one to lever up some paving slabs in the garden today and broke the bloody thing, now I've got get my wife a new one. It just won't be up to the job.

Unfortunately RV8R has not got a clutch change online yet. Gearbox removal is not covered in the Land Rover manual, it is purely engine.The main question is, do you either drop the gearbox and change it or pull out the engine? Either are possible it's a question of what facilities you have.

Gearbox removal is covered in Steve Heath's book. It contains the TVR generic guide which is not model specific. Oddly enough I was speaking to someone this weekend about this, although for a Chim, and his comment was that it was a real pain to do as the gearbox is heavy and difficult to handle. It is not, apparently, an ideal first step up from changing the plugs.
There are differences between the Rover and T5 boxes in procedures.
If anyone does remove a gearbox I would be really grateful if they could take a few photographs for inclusion in RV8R.

He doesn't want to change a Griffith clutch, it's a Giffith clutch thats needed.Pistonheads - Pedantry matters
I've just had a look at my Steve Heath S Series book, which obviously won't be directly applicable to you but there may be similarities. He says that in the V8 S, it is generally an engine & gearbox out job, then split the two out of the car. He says that it is sometimes possible to move the gearbox back just enough to allow access but that it is difficult, and on the S there may be chassis tubes in the way - he adds that he knows of people that have cut out the tube and re-welded it 
I think I'd just pull out the engine & gearbox, you can almost guarantee that you'd move the gearbox, get stuck, chop out the tube and then still find something that means you need to take the engine out anyway.
HTH

The main problem with just dropping the gearbox is that you cant pull it back far enough to disengage it. the bell housing hits the chassis stopping it going any further back. The trick therefore is to split the bell housing from the box which allows the box to pull back further and disengage. This is easier on the T5 as the bellhousing bolts can be got at externally. The Rovers are internal. Bit more fiddly. You also have to be able to undo all the linkage affair on the T5 above the box.
From what i can gather some do it as above, others pull both the engine and box together and then split them out of the car. Depends what you are doing, if its just clutch have a go just dropping the box.

Hello
I did this on my 92 4.3
the biggest issue is the box is bl''dy heavy and as mentioned to get it in squarely you have to split the bellhousing and gearbox maincase- popping off the clutch arm in the process - so getting it out isn't so bad but back in is a real game, as its very easy to pop the clutch arm off but not so getting it back on especially as you have to twist the box a little to get it past the chassis tubes.
however its still easier than taking the engine out
If you can get some help then I'd imagine its a lot lot easier, as on my own it took two trolley jacks and some fancy language to get it all back in

This sounds like a total non-starter unless you have a lot of heavy lifting gear and ideally a pit to stand in. How much would a garage charge to change the clutch? I know getting grubby is some people's raison d'etre, but I'd be doing a couple of days overtime and paying someone else to graze their knuckles for me.
Hi,
Thanks to everyone for the replies. I don't think I will be doing the job myself but I have a good mechanic nearby who has never replaced a clutch in a TVR so I'm trying to get a rundown on how (hoe) to tackle the job.
He has all the garage equipment so still wondering if the engine + gearbox out is the best idea or the gearbox broke from the bellhousing and moved rearwards.

If you do remove the clutch yourself with help or not from your friend, is there any chance of taking photos and penning a few words for inclusion in www.RV8R.co.uk? PM me.
