2010 990 SMR Clutch fluid

Post by aa_blackbeard » Wed Oct 23, 2013 1:49 pm

Hi guys,

it seems like there's no Motorex mineral hydraulic fluid for the my clutch in country!!!! does anyone know the specs of the clutch fuid? I'll try getting it from oil dealers, but they mainly deal with huge lifting equipment type of fluids, so they need the specs. I believe it's ISO 15, isn't it?

Do not use normal hydraulic oil (all the dot ones)
it is apparently incompatible with the seals that magura use in our clutch systems

Use a mineral hydraulic oil like citroen LHM (liquide hydraulique minéral )

I am using it and these cyclists have magura hydraulicshttp://www.trials-forum.co.uk/topic/128 ... yal-blood/ they seem happy with it

That's just amazing, coz I've been looking all over the country for motorex mineral oil with no success. While automatic transmission oil is all over the place, I've been thinking about it but I want sure, I'll try it when I change the slave cylinder to Oberon aftermarket after 10000 km from now.

Thanks mate

Oil manufacturers love to sell the same the very same oil in many different types of packages and claimed uses when many of them are the same.
I have used Auto trans oil in all my KTM Magura dirt bike clutches for years and all worked exceptionally well, they now use Brembo clutches which are brake and clutch fluid. :P

Me being me I'm probably over thinking this! lol

Density at 15 °C, kg/l 0,888
Viscosity 40 °C, mm²/s 10,00
Viscosity 100 °C, mm²/s 2,60
Viscosity Index 90
Flash Point COC, °C 172
Pour Point, °C -30
Acid number, mgKOH/g 0,30
Sulphate Ash, % 0,06

- ATF: various specs available, typical cost £9 for 1ltr (1000ml!!)
Example: Castrol Transmax Dex III Multivehicle Car Automatic Gearbox Oil (ATF)

Multiple manufacturer approvals make Castrol Transmax Dex III Multivehicle ATF suitable for wide ranging use.

Density @ 15C, Relative (ASTM D4052) : 0.859 g/ml
Colour (ASTM D1500) : Red
Viscosity, Kinematic 100C (ASTM D445) : 7.2 mm²/s
Pour Point (ASTM D97) : -46°C
Viscosity, Brookfield @ -40C (ASTM D2983) : 16500 mPa.s (cP)
Viscosity, Kinematic 40C (ASTM D445) : 35mm²/s
Viscosity Index (ASTM D2270) : 175

- LHM: various specs available, typical cost £9 for 1ltr (1000ml!!)

Viscosity, Kinematic 100C IP 71 mm²/s 6.2
Viscosity Index IP 226 None 320
Pour Point ISO 3016 °C -50
Appearance Visual - Fluorescent green clear mobile liquid


At the end of the day cost initially isn't really an issue when you're talking a tenner what ever way you go (however what impact might there be on time to clutch master and slave cylinder rebuilds??).........the ATF or LHM makes more sense from the point of view of having plenty of excess fluid to give the system a good flush through.
I know ATF and LHM work fine as a number of guys have said they've been using it but the specs between ATF and LHM vary a lot and even more so from the Putoline Hydraulic Clutch Fluid which, as Putoline states, is suitable for Magura and other clutch systems (and therefore I assume a close match with the Motorex fluid).
e.g. Viscosity Indexes:
ATF 175
LHM 320
PUT 90
Viscosity 40°C, mm²/s:
ATF 35
LHM 20
PUT 10
Viscosity 40°C, mm²/s:
ATF 7.2
LHM 6.2
PUT 2.6


Yeah I know.....anal geek! :eek:

Decisions decisions :confused: ............any thoughts comments?....

....and from ADVRider forum:,
".....with regard to the problems some owners have faced with the slave cylinders failing early, one seemingly knowledgeable member wrote:

the problem is sintered aluminum + mineral oil + heat + pressure. Its called a solvothermic reaction. Swap to a synthetic fluid that's non reactive with the sintered aluminum cylinder and there is absolutely no issue with the stock unit. 60+k miles and no failures. Same for every one of my customers and friends who I've swapped over to 3w synthetic fork oil.. I could make 35% selling these replacement slave but it really isn't necessary, IMHO.
"

Anyone confirm or deny?

Can´t confirm nor deny that syntechic fork oil should be used - but I replaced the original mineral oil in the clutch system to Castrol 5W fork oil when mounted Oberon slave cylinder, about 2000 km ago. It seems to work perfectly.

Hi 'Doms01'

I'm not 100% sure about the capacity in the clutch system, but would be surprised if it's more than 100 ml. I would buy 200 ml, just in case :-)
