It seems like LHM Plus is getting harder to find stateside. IS there a suitable alternative for it?

Thanks

 

use the citroen suspension green stuff, it is close enough to jaguar hsmo

 

Thanks. It's also very hard to find

 

does your leak and you need continuous supply?
sngbarrat have them in stock in US, you can import from some europe/uk jag spares shop or get it cheap on ebay, but you are right it looks like it gonna be close to impossible to find it locally, if not now than rather soon

 

Since you will not provide a MAKE,MODEL,YEAR I can only guess you have a 3.6 Liter car with power brake hydraulic system because almost ALL 4.0 cars have the 'SLsuspension-delete' and do NOT require the Castrol HSMO 5966 fluid but simply DEXRON III for the steering.

Some owners replaced the hydraulic brake system with a vacuum system.

Sometimes you just have to make a 'judgement-call' and pick an alternative fluid?

 

Thanks, It's actually not for a Jaguar. I own a couple of older RR and Bentley cars that always seem to need attention to the brakes and suspension. I suspect because they spend so much time sitting. I usually end up needing a case every year or so. Shipping fluids internationally does not seem to make sense to me so I'm wondering if there's an acceptable alternative (CHF-11S etc) that's readily available here. I should also cross post to the Citroen forums as RR licensed that system from them.

 

febi 24704 seems to be correct hsmo replacement

 

I knew that I had good reason to visit this forum. Thank you

 

You welcome

 

The last time I needed some HSMO I used TRW LHM Plus Hydraulic System Mineral Oil. I don't know if it is still available. Neither Terry's Jags nor Amazon show any stock available.

Pentosin CHF 11S very well may work, but it is a synthetic oil so it may or may not be compatible with the seals in older Jags, RRs, Citroens, etc. You might contact Pentosin to ask. Our local NAPA and Advance Auto Parts stores carry it, although the price has gone sky high.

Cheers,

I think that CHF-11S is a good candidate and readily available. I actually have 20 liters of the stuff at my hobby shop thanks to Mercedes using it for ABC suspension. Recognizing that it's synthetic, the properties are similar. I don't think ZH-M would work but in reading some Citroen forums, it appears the manual states that a push, you can use 20wt motor oil and some people have been using Mil Spec H 5606 which shells sells by the gallon. I have a gallon of this which a friend of mine gave me to use in my Mercedes Benz 450SEL 6.9. I've never used it but he swore by it.

This seems to be a well discussed thread https://www.aussiefrogs.com/forum/in...e-fluid.93983/

 

How about mineral baby oil? Anyone tried that?

 

Baby oil is suitable for babies, I wouldn't want to put it in a braking system because you can boil your brakes.

 

It would be interesting to compare the bulk modulus of baby oil to that of HSMO to see if Larry's idea could work. Bulk modulus is the resistance to compression, or the inverse of compressibility, which is an important criterion of all hydraulic fluids.

The two material safety data sheets for Johnson & Johnson Baby Oil that I found in a quick search do not include compressibility or bulk modulus. Because the oil is not considered toxic or hazardous, they aren't even required to disclose the actual CAS of the base oil. However, in addition to light mineral oil, the product contains a fragrance, so it would make your brake system smell nice.

Of course, we also don't know about seal compatability.

Cheers,

It would be interesting to test! Maybe soaking some seal material for a period of time would be an idea? Repurposing products isn't a new idea - I run Costco computer duster as a refrigerant in several vehicles!

I suppose the adding of perfume is somewhat similar practice to the adding of bitterants to industrial aerosols to prevent "huffing"

at least your everleaking granny gonna smell good with that stuff
