S1 - How do you remove the bellhousing from engine

[88S1]

Struggling to separate the bellhousing from the engine. Removed all bolts, removed cylinder, Got it about 3/4 inch away, but it just won’t come any more, wiggled, pulled, everything . Am I missing something?????.

Bellhousing will spin round the full 360.

Carl.

The bell housing can spin all the way round, so it is totally unbolted and free of the metal plate and engine. The distance at the bottom doesn’t seem as much as at the top so maybe I’ve cocked it and got it jammed, splitting it to 3/4 inch was easy. I’ll get some levers and give it some welly as Phillpot suggests. Just didn’t want to force it if there is a circlip or something I was suppose to remove from the back end etc.

Thanks both. Appreciate your help.

If I can get a bolt and nut in the fixing holes between the housing and the engine, I should be able to wind them out and jack it apart.

how your supposed to change the clutch with the engine in is a mystery. I’ll certainly be putting a new one in regardless of how it looks.

Does the bell housing mate back up to the block ok, have you tried fitting it back in place?

The result from the above operation may speak volumes

Don't force it out just yet as you may regret it

No, but it’s on a pallet and a bit wobbly. Aaaagggghhhh

Engine and box on the ground with engine resting on sump and sitting level. Trolley jack under gearbox and jack box to primary shaft level as in picture it appears weight of box is resting on it. Then crowbar the two apart

Will give that a shot. Thanks.

It worked, that extra bit of stability sat on the floor, jack at back and a crow bar did the trick. Back on its pallet now. Thanks.

The main shaft moves a couple of mm side to side, is that normal or do I need new bearings???

The layshaft is also prone to wear if it's been run low of oil in its past. No guesses to why I know that........

Your right, let the experts have a look at it. There’s 80k on the clock so probably needs doing anyway, and I don’t want to pull it out again when it’s back together.

Good news that you got it out

It’s easy when you know how, took 2 mins, just having it on flat ground with a jack at the back made a massive difference (and saved a lot of huffing and puffing) opposed to it being on the pallet. Tricks of the trade, worth their weight in gold. I know for next time and re-build. PH saved the day.

[88S1]

Yep. I’m contemplating changing the gearbox bearings myself to save a few bob, I’m a time served tool fitter (a long time ago mind) so it’s not beyond my skill set, but never done a car gearbox, not going to do it if it means taking every cog and component out though (like photo), have a million other things to do.

[88S1]

This looks a bit simpler. But will take it to an expert and get a quote to see how much, there’s a guy locally with great reviews.

[88S1]

Ouch.

Sorry I haven't come in before as I am also an S1 owner.
So now you know the gearbox input shaft can be difficult to get out if you

Thanks for that, The car is in a bit of a sorry state so Ive never ran the engine (luckily looking at the solid waxy stuff in the water ways), and the clutch was solid anyway, it was a bit of a gamble/panic buy/mid life crisis, probably not fit for the breakers yard. Actually never been in a TVR , just always loved them, so here it is, mine ol mine.

Had a look in the gearbox, oil in there and all gears looked ok but it no expert, will take it to a local transmission guy who has great reviews, see what he says (hopefully the bearer of good news). I’m going to be breaking the engine down as much as reasonably viable to check everything and clean it all up, it’s not siezed anyway which is a plus, will be dropping the sump and head off and checking replacing whatever needs it.

I’ll change that crank bearing as a minimum then. Thanks for the heads up.

Cheers Lee

Good luck Lee, it will be worth it in the end.

Pray for a clean pump!!

Good stuff. I’ll drop the sump when I get it on the engine stand and have a look at the pump. I’ll do this as next job so i know if I’ve got engine issues. Thanks for the info.

The old one can be a bugger to get out and you may finish up chopping it out in bits!

Piece of cake ..................... bearing extractor

Im liking that. Great idea.
