Definitely, I''m a lot better with a hammer than fibreglass

After finishing the hillclimb season a month ago, I was going to get the engine and gearbox out for a rebuild, but various friends at Tavern MC were planning to do the Carfax Stages at Longcross in November so I decided to enter that instead, with Teresa co-driving as she lives just round the corner

The engine is fine for the rally but the gearbox needed looking at so it came out and I dropped it off at Competition Transmission Services http://www.gearboxman.co.uk/ (who are now Quaife's main stockist for my type of sequential box) together with my 5.1 axle as the pinion had a lot of play and the LSD had a bit too much S in it

A week later they phoned with the bad news, as the input shaft had come loose and a lot of oil had dropped out, everything that touches the input shaft needed replacing together with the shaft itself and most of reverse, which came to a complete cost of £1900, but they offered a very good discount on a new 6 speed box so I went for that instead

I picked everything up last weekend so today's job was to put everything back together







It looks identical to the 5 speed except for the gold plated top plate (that's why they're expensive ) and I've gone for a 2.2:1 first and a 0.87:1 overdrive 6th - coupled with swapping to the 4.6 axle permanently (the 5.1's going in Fly ) this should give me almost identical top speed in each gear as the 5 speed so the same acceleration up the hills, but a top speed of 128.5mph
I doubt I'll need this at Longcross - it depends where the chicanes are - but its there if I need it

Spot the lock-wired input shaft housing just to be safe

While the gearbox was out it made sense to check the clutch and bellhousing - the clutch was fine but the bellhousing wasn't



This still shouldn't have made the input shaft come loose, but it cannot have helped so I bought a new one from Rally Design - it's thicker all round and even comes quick release as standard with strengthened bosses threaded M10 to mount the box to, very nice shame I had to drill a large hole for the layshaft bearing - they should do ones with this feature as they do for Duratec's, etc



And it's all in now except for the gearstick, tomorrow I'll be fitting the axle so I can do some testing

Also, after the fan coming loose in Wexford, I removed the rad to have a better look, found the rad sides were loose so that's been reconditioned as well, and I modified the fan motor shaft with a split pin as a back up in case the screw comes loose again

Nice gearbox gavin, i should be off to see Bernie to have mine and Andy Pipes type 9s rebuilt in a couple of weeks. He always gives us great service. Must say I like the 6 speed though

Just read through all of this over the course of a few days mind, what a cracking write up.

I was pleased with the quick turn around and a very sensible offer for the old gearbox

I tried out the 6 speed earlier, very nice, got to 70 very quickly on the local bypass

Then I found a nice deserted lane to set up the spotlights for the dark stages

And finally did some brake testing - too much on the front as normal, so I wound a lot more on the back - the balance bar must move by itself as all I've done all year is put more to the rear

On my car we have slid some fairly snug fitting petrol hose on either side over the adjuster threads, works a treat, although not so good if you have to use a cable dash adjuster...
I don't have a dash adjuster, but at least it doesn't adjust itself

[GavinR]

Re: GavinR's Mk2 Stage Car - DVY

That sounds a very good idea, I'll try that

I've got a dash adjuster lying around somewhere but can't see the point in fitting it as I can just reach under the dash and adjust it easily

Thanks

Longcross is Sunday 22nd November, unusually for me I've got some Service Crew (a few from Tavern MC as there's a lot of Tavern crews out, and Teresa is bringing Ian and has also arranged a backup codriver / service crew in case she doesn't make it back from holiday in time )

But you'd be more than welcome if you want to come
