Nissan Extroid Cvt - Strip Down And Repair!

I've recently pulled the CVT out of my 2000 Nissan Y34 Cedric as it had some serious amounts of small gold coloured and metal particles in the sump not to mention shockingly dirty fluid.

According to the blokes at CVT.co.nz you need to be a trained professional at rebuilding these boxes and they want $6-$11,000 for a rebuild/repair because they are one of the only english speaking extroid CVT experts in the world. Obviously I can buy a wrecked CVT equipped Gloria/Cedric in Japan and ship it over for a lot less then that, so i decided to rip the box apart and find out exactly what fails and have the parts replaced/replicated if the expensive is considered reasonable.

The box in question is the RE0R04A 6 speed CVT which will be very similar to the 8 speed found in the GT8.

I started the strip down last night and all i can say is its a nightmare. The amount of different sized bolts and clips/gears are scary. I've done the best i can at logging where all the bolts go and document everything with pictures so hopegully she'll go back together fairly easy.

Since I have only worked on it for about 2 hours (including an hour to take the box out) here are some pics for you to have a gander at.

I will provide more pictures/information as it comes to hand.

Cheers

Ben

cool. it will be interesting to see how you get on. no doubt a lot of your work will apply to the GT8 trans as well. since neither is really an 8 speed or 6 speed both are just a CVT with different 'shift' programming you can utilise giving a number of set ratio points.

I honestly have no idea what wears in them but it should look like this inside as I understand nissan use the type of CVT with a belt drive with 2 variable size pullleys. which is probably the most common type. there are a few potential spots though I can think of off the top of my head.

and here's a good little gif for those who have no idea how they work.

      Wife wanted basket things in the wardrobe in our temporary house. Thought about ripping our the wardrobe and fitting the entire IKEA set, but it's a temporary house and we want to move in a few years. So IKEA advertises this as a 50cm unit, however the actually basket and rails measure 46cm wide. Only issue was depth, IKEA stuff is quite deep, where as the builder special junk is super shallow at less than 40cm. Send it, chopped the rails, then offset the mounting holes, job done, happy wife, less shit scattered all over the bedroom. Did the same to the other side too. Also drove the Skyline shit box today, dropped off oil at Supercheap Auto. I didn't realise they only now take max 2x bottles per visit. I visited 2x Supercheap Autos.

      I've seen similar actually in my situation. You never know what tables are attempted to be used when the car thinks it's -99C or +200C. The fail state is not usually that extreme but you know what I mean - it was in my case though! This is where being able to read all the sensors is useful cause you see this stuff really quickly.

      The above is very important. However as long as you keep timing relatively low, it's plausible to make your own knock ears and plausible to learn to tune with a modern ECU that can do wideband O2 correction like a boost controller. I mean if you only have one viable road to even drive the car on, learning to tinker to this level may be worth doing given you can't do much else with the car...?

      I find the fact that the rear plate has to be bent inwards at the rear not so bad: but the front is just awful: It's like come on. (these are my very old, now retired/turned in plates) TBH it is a lot of money to fix a minor issue, the fact I said "I'll never really spend the money on doing this" is why people ended up buying them as a gift for a 'car guy' who can be hard to shop for.. for car guy things.

      I just bent the ends of my premo plates. It even went through Regency like that after the engine conversion and the inspector (a great bloke!) just squinted his eyes and said "I didn't see that". Plates, and how they look, are just something that have zero importance to me.
