I’ve got a 089/129 gearbox that I can rebuild and supply if you’re still looking for one?

Yep. Got one I can rebuild @Stevendjk

Mk2 crownwheel needs to be machined to suit the blackline - the same as the quaife. The mk3 crownwheel is bolted on. Couldn’t say if the diff fits in a Meg box though I’m afraid.

Good to know mate! They work well in the mk3 clios too.

Lol

Did a trial run with the diff fitting this evening. Fitting was fine and no preload adjustment required! Heated the crownwheel and fired it on the diff. Only negative is the thread for the nut isn’t as nicely cut as you’d get on a quaife, but, the nut tightens down to torque spec, so all good!

For anyone else interested in the blackline diff, I now have a blackline diff in my possession to fit in a mates gearbox. It’s nigh on identical to the quaife, and I will be fitting it in the box tomorrow evening for a dry run - just to see what the fit is like. If it’s all good, I’ll then fit...

Right ok fair enough. Well there’s a strong possibility that there’s an unhappy bearing in there then if you can hear a droning noise. Unfortunately these cars were built in the knowledge that they were going to be abused. But the diff will make noises when it’s jacked up.

They all make a noise when they’re jacked up, so I’d advise that you drop the oil out of it and make sure the oil has no debris/particles in it. The gearbox code you have is a jc5 089. You ideally want another one of those, or a 129 - this gearbox has a speedo drive as does your 089. I can’t...

Tag didn’t work for some reason 🤷🏻‍♂️

@Touring_Rob do you want all the Renault part numbers? I have the correct ones for all the bearings in a 130 box. Or are you only after specific ones?

The bell housing of a 197/200 box is huge in comparison mate. Only real option is to find a 6 speed TL4 from a dci as they have a smaller bell housing from memory, then fit the 197/200 gear kit inside the box. Next problem to overcome is the crank sensor position as it’s different on the TL4...

None.

You’re welcome mate 👍🏻

Yeah you can do it. I’ve done loads. You need to drill the hole straight and then transfer the speedo drive bits over from the 129.

Yep that’ll work fine with a 089 👍🏻

Email this guy: allan@bridgecraftmotorsport.co.uk Tell him I sent you and he should be able to help you out mate.

You need the upper casing half that’s got the twin taper bearing setup. The later boxes had a taper bearing and a parallel roller bearing, so you can’t use them as they’re not compatible. If in doubt, upload images of the casings you’re offered and I’ll tell you if they’re any good or not.

I can do mate yeah, but it might be worth checking the cost of shipping first buddy. The Brexit morons have made life seriously hard work

Well that’s no bother to sort mate either way. I’m Lichfield Staffordshire, so midlands basically. If you can box it up, you can get it delivered for about £40 using the ups option on interparcel. Just have to put it down as car parts! Put it down as a gearbox and they’ll refuse to take it lol

I’ll say about £400 if I’m doing synchros and seals as well mate?

Well generally 9 times out of 10 they’re repairable. The only time they’re not is when it’s damaged the casing and allows the oil to come through into the clutch housing. I’ve got plenty of spares to help keep costs down as well 👍🏻

Yeah that’s the mainshaft bearing has failed mate and allowing it to move around - there will be metallic particles in the oil. Guaranteed lol

In fact, that could even be a clutch cover failure after listening to it again. Drop the oil out your box and have a look at the colour and fit bits of metallic particles.

Lolololol yeah that sounds pretty unhappy doesn’t it 😂 deffo sounds mainshaft bearing. Does your car run a speedo? If it does, then that box *should work, but quite why they’ve listed a jb3 box up as a 182 gearbox is beyond me!

The dci boxes have shite ratios and are also no stronger than the 129. It’s the torque that kills the jc5 unfortunately. The only way to not kill them is run decent oil and change it regularly. The only potential option in terms of jc5 is to get the 089. They have taper bearings on the input...

You’ll always have power (12v) at the injectors mate. They’re fired by the ecu giving them an earth signal, so I’d say it’s possibly not the cal file.

Nothing to do with me mate 🤷🏻‍♂️

Can also confirm, that bear sits in other peoples piss in Gucci suits.
