Yes people, progress with No27 is slow but I keep running out of cash - I reckon Racing Rod overcharged me in the first place ;-) Only kidding Uncle Rod. I love her even though she's never moved from my garage. Anyway, I don't care if progress is slow so long as I do it right.

So the status of No27 is that she's exactly as sold to me by Uncle Rod i.e. minus an AJP engine. HOWEVER I have recently acquired (read "spent all my overtime money again" on an original Tuscan Challenge engine.... the RV8 version. It has spent the last few years in the careful ownership of a nice chap called John Forsyth in the back of his Pilbeam hillclimb special.

So my garage floor now has a 1999 Tuscan, an RV8 Tuscan engine and a T5 bearbox all neatly laid out but not altogether.

I need a bellhousing for starters (more overtime aaarrrgghh). But that aside I'm not sure how the two mate together........ the T5 has a splined shaft end with 23 splines but the hole in the end of the engine (when looking through the flywheel) is about the same diameter but with only 10 splines i.e. a much coarser pitch. Are the two supposed to mate or is there an additional component inside the bellhousing ? I suspect there isn't, so what is my best course of action - change the gearbox shaft to a 10 splined jobby or the engine to 23 splines ?

Thanks !

Richard

That sounds like good news - just need to find out how to take the existing plate out (looks straight forward enough) and determine an appropriate replacement.

Thanks !

Thanks Graham.

I'll post some photos shortly so you can see the clutch assembly.

That bellhousing looks pretty good. I see a lot of people suggesting using an auto bellhousing and then fabricating a plate but I don't like the sound of it a) it sounds a lot of machining work and b) it sounds a bit rubbish. So I would prefere to buy a cast housing made for the job.

Cheers
Richard

Okay got some photos.

First 3 are of the clutch end of the engine and the last two are of the T5.

Sorry my photography skills aren't great.

Notice on the following photo, there is the end of a bolt just visible at the 10 o'clock position on the cover plate - any ideas how this is accessed to remove the plate ?

Pleased to hear the gearbox is ready to go straight onto the JE bellhousing...... "Dear Santa, I've been a good lad all year. Please give me a JE bellhousing"


The flywheel is 260mm diameter to the outside of the teeth. I started loosening the 6 allen bolts but I get the distinct impression that the vaned parts of the clutch just behind the cover are sprung and will shoot across the garage floor when I take the last bolt out. D'ya reckon it'll go back together without the need for a hydraulic press or something. Doesn't matter if you don't know - its got to come off anyway so I might as well give it a go.

Just added some more photos of some spares that came with the car. One is the water pump casing DSCN0940, 948 & 950 (no internals though). You can see in 950 that its not a closed casing so I'm a bit confused there. Is the electric water pump the better way forward ?

Any idea what the top item in photo DSCN0943 is ? I assume the two black boxes below it are some sort of ECU's.

Appreciate your help by the way and would love to see your photos.

Cheers !
Richard

The ignition system that was last used on this engine was the MSD jobby in pic 944 http://community.webshots.com/photo/506618349/507394 and he did show me how to wire this. It comes with two rev limiter chips 7000rpm and 3000rpm (for wet).

Did you have to cut any of the chassis cross-member to get the engine in ? Also, did you fit it with the gearbox attached to the engine or did you fit the gearbox separately ?

I'll get in touch with John Eales next week about the clutch/flywheel.

Any idea what the two parts on the left of pic 941 are ? http://community.webshots.com/photo/506618349/507394
The bits on the right are spares for the end of the drive shaft so i just need to transfer the pulley ring onto my engine to drive the alternator presumably (damn, I need an alternator - more overtime!). But I can't work out what the two parts are on the left of the pic ????

Hi Graham

I'm in Northumberland but next time I'm in your area I'll get in touch - how do I email you offline... through blackcat racing ?

Just taken the clutch plate off - easy.... and nothing flew across the garage floor

The flywheel is actuall 268mm dia and had 6 8mm holes on 200mm PCD. The clutch plate mating face on the flywheel is 185mm dia which I assume is for a 7 1/2" clutch. I've emailed John Eales to see if I can keep this because it already has the starter motor fitted and I'd rather not spend £680 for his slightly larger dia flywheel if I can help it.

Going to check out your alternator link now.

Cheers
