Espace 24v ZF 4HP20 ( LM0 ) OIL TYPE when changing

[renaultbiler]

Ive already started the gearbox removal, and it is possible without removing engine - someone has done it before and it was said to be "okay" and got a brief description over the phone today. So now remains a couple of big bolts and then lower the engine on one side to pull off the box. Hopefully i will get the remaining time tomorrow before we go on a good long weekend without kids. Dont know if i make any update on the progress but i will post as soon as possible.

In addition i have two more JE's standing here now - one with faulty ABS and one non starter due to electrical problems. So i hope the three of them will have some nice conversations during the next days And i will try to fix them as soon as possible since the neighbours now are pretty sure i am completely mad in my head

HAHA! Look at the positive side: Now your boring neighbours with boring lives finally have something to talk about! Like my neighbors, who has been looking at my Murena standing outside on the little road in front of our house without rear suspension and wheels for a week. But they know me by now...!

Quick UPDATE

L@@K, the gearbox is out

Approx 4 hrs work summed up, but i'm sure it would be near to half if i was to do it again. So now my transmission is off to Berlin for rebuild as they had an error in stock and no LM0-005 available. Just as good, i'll be getting back my own box again.

Well done, Tom! It looks very good in there. I hope you'll get your box back quickly. It will be nice to know you have a "fresh" one in now.

New plans for the gearbox

GSB Berlin has a fantastic delivery and pick up service anywhere in europe EXEPT Norway that is outside EU - so in the end it seemed like a lot of hazzle with transportation and cash euro payment to the driver upon delivery in Sweden (the closest they could offer to meet me). A shame since they have really good service both by email and telephone - you can actually drive your car to their facility in Berlin and drop it off and get it fixed by next day - and they arrange a hotel and a rental car while you wait. Unfortenately my car was not driveable, but if it was i might have done just that.

So now it is on the way to ZF's facility in Gøteborg Sweden for rebuild and bench test and is promised back in about a week delivered to my adress. A bit more expencive but not much, and since this goes through the Norwegian ZF representative i feel that the warranty might stand stronger IF something should happen within 6 months.

[Anders Dinsen]

Too bad the Berlin solution didn't work out, but I'm glad to hear that you have found a good alternative. I agree with you that warranty service will definitely be better this way, so I suppose you'll get a little out of the extra payment. by the way, how much will it cost?

The GSB service sounds really good, especially the solution where you go there and stay one night in Berlin while the car is serviced! I think I'll give them a call as I now have a new engine - so why not a matching fresh gearbox?

GSB Price was 1349 euros plus shipping for exchange box/rebuild existing. But they operate on different pricing based on how long warranty you want and wether or not you are a mechanic or private.

My ZF price are approx 1900 euros IF no breaking exists on the gearbox casings.

What seems to have happened is a faulty bearing around the converter shaft, but this is a fairly good guess only as we where unable to pull off the converter (probably due to this).... used no force on it though. But it also makes sence with the noise and oil leak.

[renaultbiler]

And since this topic started out as an oil type thread, the ESSO LT 71141 oil IS the same oil you get on Renault LM0 bottle - exactly the same color and very distinctive smell. 100% identical.

[Anders Dinsen]

Thanks for sharing the prices, Tom. I don't think either is too bad, actually. I remember being given a price in the range of 30000 DKK, that's about 4000 EUR just for the box repair, when I consulted a local gearbox specialist back when I got our car four years ago.

Cheers,

Quick update - they called from ZF today and offered a new converter instead of exchange unit since they where currently out of overhauled ones and a week extra to wait, they charged 180 euros extra if i choosed a new converter and ofcourse i want a new one!

The reason for the breakdown was the oil pump, dont know if i got it all correct but apparently a gasket from the oil pump shaft went off and this eventually destroyed the sealing around the converter shaft causing a leak there aswell. Something like that anyhow. Rest of the box was fine, but still it is ofcourse rebuilt with a few available upgrades/improvements in addition to pump, filter and all the rest of it. Recon it will be like new again and i will get it back next week if it passes bench testing.

[Anders Dinsen]

Hmm, it sounds like an oil pressure problem has eventually destroyed the seal causing the leak? Anyway good to hear they are progressing and giving feedback on the problem. That's always a good sign. How did you get in touch with them, by the way?

Got this rebuild arranged through a very professional Bosch Diesel Center that i use for parts etc - and it is run by a friend of mine They have various partners they use and this is through one of them.

So i guess my prices are very good on this one - and the follow up is also very good.

I am told that ZF has a new and modern facility in Sweden and some boxes are fixed there and some are sent to Germany. This one is dealt with in Sweden.

Today the repaired gearbox arrived safe and sound, so i will put it back in during the weekend

[Anders Dinsen]

Congratulations! That was a quick delivery and return, I think. I wish you good luck and fun with the reinstallation. It looks good!

Hopefully the last UPDATE in this matter, the gearbox is in place and working like a clock. Just did a 30km test drive and it is shifting and driving absolutely lovely. Constantly logging temperature etc with NXR during the test drive.

The mileage is now below 1 ltr/10km in average on this spesific route and it was never that low before. So i suspect the gearbox to have been cause of several minor "misfire" problems that i thought was engine related (that is, i hoped it was engine related - but now im glad they seem to be gearbox related....).
It is all gone and the engine/gear assy is realy cozy like a cat down there now.
