UPDATE:
Bit of a more interesting update this time with pictures
On thursday I made a 4 hour trip to pick up a gearbox that needed a rebuild because of crunching in 3rd gear. The plan is to strip and rebuild this box with all new synchros, bearings and seals along with cryogenically freezing followed by shot peening all the shafts and gears. The synchros in 3rd and 4th will be replaced with updated iron ones (I think they are iron or steel) these will also be just cryogenically frozen to improve strength.
On friday I began about setting out to strip the box down to base compoenents and shafts etc, was relatively simple, had one hiccup that the shafts became stuck in the wrong half of the box, with a chat with Mr [MENTION=29]foxspeed[/MENTION] it turned out they just needed a little tap to free them. Over the weekend I have removed various bearings and discovered a huge input shaft bearing failure, which could also be another week spot in these engines? Anyway I'm off to Greece for a week so wont be abe to make any progress (I wish the engine would fit in mt suitcase :lol: ) anyway some more pictures and I hope to have this box completely stripped and ready for treatment and re assembly by beginning of next month. There will also be more progress on the engine due to a massive parts order happening when i get back off holiday, then the car will come off the road in november ready for its transformation, cant wait!
Oops :lol:
Thanks guys.

It's alright mate, I'd be ripping yours apart anyway, so ideally wanted a box like this that was faulty.

UPDATE:
Not to much progress as Ive been on holiday and had callipers to do. I have managed to completely strip the output shaft of the gearbox, this was done by using a bearing puller/splitter to remove the end tapered roller bearings, with these off I took the shaft to work and used the 20 ton press to press the gears off of the shaft, it was then disassembled and laid out in order and then thoroughly cleaned with solvent degreasers. The input shaft is proving a bit more of an arse to disassemble, there is a nut on one end that is screwed onto the shaft to hold the bearings on, problem is that its bloody tight and holding it securely is proving a pain. i did try it in a lathe 4 jaw chuck but it still would turn. I plan on getting an old 197 clutch and using the spline to hold the shaft securely while I undo the nut. Also I have started cleaning the cases and will shot blast the outside this week and then remove all the bearing races and seals and then give it a lick of paint. Anyway im sure ill have more to show you next time
Thanks guys

Hello again guys
Not to much to update on again. But first things first Ive just been enjoying the clio this week, finally cleaned it in over a month and went for a meet up at Eurospec for a dyno day. It was really a great day and really glad how much my clio made, 193.2HP and a reasonably straight curve, these rollers are also known as the "heart break" rollers and normally read lower than others, so there is a possibility that its making a wee bit more. It will be hopefully a good 150HP more than this by next time its on the dyno
Anyway back to the build, and to my relief I have finally undone the nut on the end of the input shaft. I couldnt find a clutch plate for love nor money to help me hold shaft so I could undo the nut. Therefore I had to make an aluminum collet in order to hold on the spline so I could get a breaker bar and get it undone, man it was tight! Also managed to remove all the bearing races and seals from the bell housing side of the casing, I then shot blasted the outside ready for paint. The casing was then cleaned 3 times in hot soapy water to remove all dirt and sand.
All the seals, synchros and bearings are being delivered this week so I can then get the bearing races installed and also paint the casings.
Thanks everyone.

That's the spirit, can do you a head and cams next year for a good price
I would have gone along myself that day but due to taking the car in this week I didn't really need a figure and frankly the miles and money I could do without needlessly spending right now! If they organise another next year sometime I may go.

And gain about 3 hp :lol: yeah was a really good meet, lots of cars and some very tasty evo time attack cars
I'm sure they will, it was a big success.
