The problem Dave is that he's in Cornwall Far from any embassy or decent sized university, and there aren't that many Japanese people in Cornwall either. I guess there might be a sushi place in somewhere like Truro maybe?
(don't worry - I'm half Cornish. My mum is from Saltash, and my parents live in Bude now). |

That LHM stuff is probably very similar to what is in it. How would you describe the smell?
I used to use LHM in my mountain bike brakes because it is the same as the mineral oil for the brakes, only it is a fraction of the price! Is there not someplace that you can send a sample to and they'll tell you what it is? I know you can do that with engine oil to tell you what kind of oil it started off as, what has leaked into it, and what is suspended in it, i.e. bits of bearing. |

Hi
We dont have universities here in Cornwall.We only got schools a little while ago.
The fluids page is the key...thanks rich...top job (Saltash... ged on....u nearly a janner then lol)
The system is probably circa 1L of fluid total so looking at the two lowest items(right hand page) suggests ATF/ATF SP or a GL4 spec.
(Toying with translating Japanese i.e order of words etc gives very close results to the ATF SP entry and the heading on the other page about the systems operation).......although I might as well be reading a sushi menu.
Higher spec ATF's also are documented to conform to GL4 spec....so as these fluids seem to be intriniscally linked by their specifications.
ATF is also pretty passive so doubtful it will ruin the seals.
Also now knowing the approx viscosity range suggested for these type of gear type pumps the cst of ATF SP and GL4 seems in the correct range.
I think we might have cracked it met.
I need to get a couple of metal hydraulic lines made to replace some rusty ones but looks like Ill be putting it all back together soon.
Wish me luck
thanks to everyone for their efforts and discussion. |

I am in the process of trying to change the rubber pipes that go to my ATF cooler and have been in touch with several hose companies.
The overwhelming advice is that ATF is very aggressive and attacks lots of rubber compounds and only certain ones are suitable for ATF.
THIS PAGE says:

O-Ring materials that are NOT SUITABLE for using in the environment containing Automatic Transmission Fluid include
Butyl: Butyl (IIR) is a synthetic rubber, a copolymer of isobutylene and isoprene.
Ethylene-Propylene: Ethylene-propylene (EP) is a copolymer of ethylene and propylene.
Natural Rubber: Natural rubber is a product coagulated from the latex of the rubber tree, hevea brasiliensis.
Silicone: Silicone is a semi-organic elastomer with outstanding resistance to extremes of temperature.
Styrene Butadiene: Styrene-Butadiene rubber (SBR) has properties similar to those of natural rubber.
Vamac: Vamac is the tradename of a class of Ethylene Acrylic elastomer (AEM). |

Hi
oh dear lol
Take out a rubber o ring seal in ur cooling system and it will have been attacked in time but only in contact with water/antifreeze, brake fluid attacks seals in ur braking system,gear oils attack certain metal parts of diffs and LSD's.....
I have read stuff in hydraulic forums about compatibilty is different depending on whether seals are dynamic/static/hi pressure or lo pressure.Which also adds to the confusion.
There are no o ring seals on the high pressure in the system side and all o ring seals on the lo pressure side are static.
I have got a small supply of o rings and had already thought about getting a litre of each for a compatibilty test.

It is a bit of a minefield!
I have got some NBR rubber pipes for my cooler that almost everyone says is OK - except one supplier who says it will be dissolved by ATF.
So I am still searching for something that is compatible with ATF and might end up at the dealer and buying OEM pipes - but the dealer isn't an option for you if they haven't any idea on your system. |

Have you tried the Australian Mitzy websites as they were importing Mitzys, Nissans and Toyota's from Japan before the Brits could even spell Japan also the American and Malaysian websites as they also speak English and were importers of Japanese cars. |
