For a ZF 4HP22EH transmission ? Castrol Transmax Z has been my go to syn ATF for a very long time. Is it still the standard for Dex IIIH type fluids ? or are there more modern formulations that surpass it now ?

This is something I've pondered for a while, Weismann's famous (in the late sixties/seventies/eighties) road racing locker and latterly the Kaiser Locker from Brazil use a sprag clutch type arrangement to fully lock under load, ie. they have a series of rollers running in a case that cam out and...

One for Bruce and Mola. How comparable are Industrial gear lube specs with Automotive ones ? Would this particular lube (Alpha SP220) http://www.castrol.com/liveassets/bp_int...ange_eu_tds.pdf go the distance Ok in a centreline spiral bevel and a hypoid diff ? (both require xW-90 lubes, and at...

Any suggestions, I really don't want to pull this assembly down as the O ring that's leaking is behind a critical (fixed) pre-load adjuster and it's a right royal pain in the posterior to get to.

This is a bit of a follow up to the Q I posted the other day. I've looked and can't find a comparison between these specs on gear, bearing wear and spiral bevel gear wear (comparing between the CAT and API spec) I realise that the CAT spec also addresses wet clutch/brake performance, but I'm...

My old Fiat 550 tractor specifies engine oil (20W-40) for the transmission/hydraulics/diff and final drives (which are a separate compartment) FWIW brakes are dry, not wet, engine and PTO clutches I'm not so sure of. CAT TDTO TMS looks like it might fit the bill a little better...

Fallacy or fact ? If so, what speeds are we talking about ?

OK, I have to ask this as it's really been bugging me. Since when did a ride on mower become a 'tractor'?? How can something with a twin B&S or Kohler be considered a 'tractor' ? Am I being a tractor snob 'cause I have what I feel is only a small tractor yet it's a diesel, is rated at 55HP...

What does the brains trust (ie Mola and Bruce and anyone else qualified to comment) think of straight high oleic acid canola as a bar lube without any additives ? A number of pro loggers and cutters on another board are doing this. I suggested it might be a lot better with an additive like...

Apologies if they have been posted before. They detail the specific problems of the GM V6's and how the rust-sludge occurs through faulty IMG's, radiator caps, system design and the OAT chemistry. http://www.imcool.com/articles/antifreeze-coolant/dexcool2007Part1.php...

Bacteria and its Effects on Coolant Shelf Life Page 9 KEEPING COOLANT ‘HEALTHY’ Complete fill style radiator coolants are a haven for bacteria of all kinds. Some airborne yeast bacteria are attracted to coolants, but this can be dependent on the inhibitor chemicals used. A different inhibitor...

"While SIN RG110 has some limited slip properties it is not designed for these types of differentials. SIN Gear 75 or 80 should be used. Use with caution if there is likely to be water contamination in the gearbox or differential as the additive system is water soluble and seal degradation may...

They have official approval from Volkswagen. Us Aussies tend to knock this smaller blender as they generally state 'meets' but they have official approval from VW for one of their low SAPS oils. Interestingly it appears the testing costs ¤1340.00...

I know this has been discussed in the past, particularly by Doug, unfortunately we all know how well the search function works so... What do I look for when dropping some oil onto some paper,and what type of paper is best ? eg. white or brown ? thanks.

....and specifically say not for petrol (gas) use ? Currently using an ACEA E4/E6/E7, CI-4, MB 228.5 l, Cummins 20078, Volvo VDS-3, MAN 3477/ 3277CRT, etc, oil that is not recommended for use in petrol engines. Anyone hazard a guess at the add package or specific adds that may used in diesels...

for local consumption. Exxon have applied for a certificate for the importation of a 'polymer of low concern' (PLDC) http://www.nicnas.gov.au/PUBLICATIONS/CAR/NEW/PLC/PLC0700SR/PLC789.asp http://www.nicnas.gov.au/publications/CAR/new/PLC/plc0700FR/plc789FR.pdf Unfortunately the type is...

This is a Group III (Australian blended, Korean sourced base) 10W-40 ACEA E4/E6/E7 Euro spec HDEO that also meets CI-4 as well as various Euro Engine manufacturer specs. NOACK is 9.5% which I think is pretty impressive for an oil that isn't a PAO/ester base. 13.1 cSt is at the low end of an...

What would be considered a 'normal' oil operating temp in a light diesel, and what should the maximum be ? (thinking operating viscosity here, disregard syn/GIII vs mineral base for oxidation purposes) Currently logging with a thermocouple on the outside of the full flow oil filter (it's...
