Backward thinking to me.

Shame about the box, that brass looking bit is probably a syncro

well it already had MTF in it and it was like water when we took it out, Tim made a phonecall to someone he trusts and thats what was recomended, so thats what he did

I run really thick oil in my box to. And that box has done 25-30,000k's of racing and targa with no issues as yet (touches wood). In fact the oil i run in my box is a 4wd oil, and another car that i know uses tractor oil in its box. OEM oil is designed for oem conditions, not for crazy amounts of track work.

Coupe-R · 24th July 2007, 09:10 AM

Hmm interesting, I changed to 80/90 oil and changing gears while cold was a BITCH.

How do the boxes go with the 4wd oil and tractor oil when cold?

Remember gearbox oil isn't just about viscosity.

I run Motul 75/90 (Pretty much the honda MTF 10w/30) Different weighting system.

They seem to go just fine. I have never had a problem with mine. The only problem i have is getting the oil, because it is out of japan.

Ah yes I think you have told me about the stuff you use 8)

doo0T!doo0T! · 24th July 2007, 11:09 AM

I have always run Castrol magnatec w10-30 in my gearboxes up until now when I decided to try MTF. (castrol recommends Magnatec in S and L series gearboxes)
To tell you the truth next time I change it I'm going back to Magnatec, the MTF just seems way too light to me, I'm feeling a lot of vibration and bearing noise in nuetral at idle is noticable with the MTF where it isn't with magnatec. The shift is also a little bit notchy at low revs too.

When I was pouring it in I was surprised by how thin it is.

Deanis · 24th July 2007, 05:21 PM

why dont you guys run gear box oil coolers, surely its not hard or expensive to do? a small pump and a heat exchanger, drill some holes in the box and plug them in. might save $$ on oil changes all the time and broken boxes.

dazznz · 24th July 2007, 06:39 PM

we just pulled tims box out and took it to bits. Im sure he will let you know what the deal is with it.....

Uh oh...

timmiblc · 24th July 2007, 07:41 PM

All the talk of what oil does what is pretty much redundant now - the box is rooted.

Car's off the road until I have the money to repair it or get another one, funds won't be on hand for at least a month, maybe two, and quite possibly three.

It'll be rebuilt or replaced for NIMM though.

Oh well I guess we know what happens when a box has no oil, I guess I can be thankful that it didn't completely seize and blow the clutch as well or worse.

Horny_Devil · 24th July 2007, 07:45 PM

what was actually wrong with it tim?

and u know u still have my helmet at ur place

ill have to pick it up at some stage

timmiblc · 24th July 2007, 07:47 PM

Yeah I saw it there this morning, was going to pm you.

Can't watch the video of the box blowing, almost makes me cry.

Dunno from looking at it what gears do what etc, but it's gonna need a rebuild at the very least with new parts.

Yeah first it pops out of third gear and then won't go back in :evil: :evil: :evil:

And because the running of the day was complete arse I didn't get any decent runs at the track either (before the box blew), so a bit of a waste of time.

doo0T!doo0T! · 24th July 2007, 08:29 PM

I'd be happy to take a look at it if you want Tim.
Did it overheat? Is there any blueing on the cluster? The refusal to shift in and out of third sounds selector fork related to me.

Well it's in bits in my shed at the moment, and there are teeth that are munched, but being uneducated on all things gearbox I can't really say what's wrong with it apart from it don't work.

Happy to have you over for a beer and a yarn if your keen Mike.

Horny_Devil · 24th July 2007, 08:49 PM

Theres the edited version of the video

Coupe-R · 26th July 2007, 12:02 PM

Doubting it would have been a selector fork, they are so simple and don't have huge forces on them. Also the selector fork doesn't rotate, and i doubt would be hugely affected by running no oil, unlike gears and syncro's.

After MANY k's the secltors can geat a little slop in them but mostly the syncro's will wear. In this case with no oil its probably a gear thats shat itself.
Sounds like gears and syncros are munched to me. TOO HOT with no lube.

Yeh when Victor chapman raced/drifted that EK civic it had an oil cooler off the gearbox.

Plate LSD will heat up the gearbox oil also!

Esprit · 26th July 2007, 12:12 PM

Bad luck Tim.... if it makes you feel any better, "Project Titanium" has hit a lengthy and costly delay and I'm now going to have to pull finger to get it here for October and certed for NIMM

I feel your pain.

Must catch a beer sometime, my shout.
