Ditchdiggerjcf Posted July 1, 2020 Author Share Posted July 1, 2020 Lots of folks will run atf in motorcycle trannies. They shifft better and last longer. I am seriously considering it in the the 2 stick that I am fixing to dump all the oil out of to install a PTO.

Maxidyne Posted July 1, 2020 Share Posted July 1, 2020 Unless you've got a good reason otherwise, uses what's recommended. As for using tractor hydraulic fluid in motorcycle transmissions, most share their oil with the engine so hydraulic fluid is a no-no. Harley's are rather fussy about transmission fluid so best to use what's recommended, and a lot of the BMWs use what is basicly an automotive driveline so the usual 80-90 weight hypoid is recommended. However, BMW built some lemon transmissions a couple decades ago, and we found the best way to limp them along until a rebuild could be done was to run 75-140 weight transmission fluid, whose only other common use was Mack rear ends!

Ditchdiggerjcf Posted July 1, 2020 Author Share Posted July 1, 2020 Talking dirt bikes. They see about the most severe conditions you could ask of a transmission. Lots of folks run some sort of atf in them. Quote Link to comment https://www.bigmacktrucks.com/topic/63113-hytran-in-2-stick/#findComment-454587 Share on other sites More sharing options...
Ditchdiggerjcf Posted July 2, 2020 Author Share Posted July 2, 2020 Ttt. Anybody with any experience doing this? Hytran? Hygard? Cat to4? Any sort of gear/hydro oil?

mrsmackpaul Posted July 2, 2020 Share Posted July 2, 2020 Hytran would work fine, it's thin, runny and is built for extreme gear use amd as a bonus it wont froth and can do hydraulic work as well Hytran feels like a similar viscosity to what you might normally use in a Mack box According to Google Hytran is a sae 10 and a sae 50 is what Mack recommended Is this one fith as thick or is it some other measurement ? Dunno sliding scales and what not ??? I know it feels similar as it runs thru your fingers I dont know why you would want to but if you chose to I think it would work fine Paul Quote Link to comment https://www.bigmacktrucks.com/topic/63113-hytran-in-2-stick/#findComment-454691 Share on other sites More sharing options...
david wild Posted July 3, 2020 Share Posted July 3, 2020 Long before I was stuck on a road bike I raced dirt bikes and never heard of anyone using ATF in the trans ???

Maxidyne Posted July 3, 2020 Share Posted July 3, 2020 I'm guessing the OP has buckets or even a barrel of Hytran sitting around and can't afford enough proper gear oil to fill a Mack transmission.

Freightrain Posted July 3, 2020 Share Posted July 3, 2020 In today's cars, they use ATF in the 5-6 spds. They have to due to all the needle bearings. Gear lube would never squeeze through those tiny areas. Old Spicer boxes needed engine oil for similar reasons. I suppose if the box was new enough it would be okay? If it was "loose", it would likely rattle and bang around from the extra clearance from the thinner fluid. I'm ready to mix some oats in my triplex to help fill in the gaps and quiet it down!!

I don't have a ton of slop in mine. I am thinking they may actually shift easier with fluid like that. I am seriously condidering experimenting with it. It wouldn't be horribly expensive to swap it back out if it makes noise. I was planning on adding my usual gallon of lucas, so it may not make much noise at all.

mrgumby Posted July 3, 2020 Share Posted July 3, 2020 I know I guy who uses as he says 75% synthetic and 25% regular 90wt gear oil in his he says it’s easier to shift in the winters I guess that’s would be a synthetic custom blend oil 1 Quote Link to comment https://www.bigmacktrucks.com/topic/63113-hytran-in-2-stick/#findComment-454775 Share on other sites More sharing options...

I'm not chastising. Rather, I simply asked him to refrain from using profanity. The individual repeatedly used the word sh*t in posts, and finally dumb*ass. I politely suggested that he might not use such language here, because we don't want Barry and Watt's Mack to face problems with content issues. The other individual did not use profanity. A bit of dry humor is tolerable. Quote Link to comment https://www.bigmacktrucks.com/topic/63113-hytran-in-2-stick/#findComment-454779 Share on other sites More sharing options...

My apologies if that was taken as an insult. Usually when someone is substituting "off label" lubricants it's to save a buck or that's all that they have available, and I've been guilty of such mechanical crimes when in a pinch. In this case the OP accepts the risks and is willing to change the oil again if it doesn't work. That said, I'd be tempted to try a multi-weight synthetic oil that meets Mack's specs first, then if the hard shifting persist look at other causes. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/63113-hytran-in-2-stick/#findComment-454780 Share on other sites More sharing options...

It came OEM in all 4 of my CAT 7155 semi auto trans and the Oshkosh 18000 transfer cases. Only thing I found when I serviced them a year ago that the current HYTRAN fluid is Zinc free which prevents wear on hard contact points in an auto /semi auto valve body. No issues in any of the transfer cases, in fact in cold weather they range shift easier and are quieter. Viscosity wise I put the lube at close 30wt. Oshkosh and Cat both specificity Hytran or Mobilfluid 424.

Popular Post Red Horse Posted July 4, 2020 Popular Post Share Posted July 4, 2020 Well guys without taking "sides" this old guy likes both sides of an issue. Now at the risk of getting flammed, when I watch Hannity, Every now and then I say..."cut the bullshit" . Trump will say some completely dumbass thing and Hannity lets it slide. and lets face it guys..He does say stupid shit. Not senile stuff like sleepy Joe, but stuff that is let's say .."far from accurate"? Remember when Covid was going strong in NYC? Trump is making speeches that they are bringing in "Freezer trucks to store the bodies.!. Uh Donald, they are "reefers"- and you don't Freeze bodies! Then just recently.."I've saved millions of lives".....he was talking about all his good work in handling Covid. Be honest-your first thought .."millions?" The way I look at it, the people that want him to win, have an obligation to try to get his handlers to get him in control. The election is his to lose. I said to some liberal Left coast relative of mine the other day about all of his "lies" that supposedly get tracked by the left, don't confuse outright lies with exaggeration or mis statements. Example. He was talking about what a great company Boeing was. "They were flying covid supplies in the biggest plane in the world..carries 63,000 lbs." (Or maybe 61? i forgot) Uh Don, I think a 50 year old C-130 does what? 45,000? C-5? Over 200,000! Is that a lie? No its a misstatement. Ah but I'm getting sidetracked- my initial point was two sides to a story make for maybe a better conclusion And cut me some slack-I've been married 50 years and if I get divorced now it will be over my support for trump. But as I tell my wife.."did I work with assholes in my 44 years? Yes. Did I have subordinates that were jerks? Yes But always I would say were the results usually good? Was the objective met? If yes case closed. That is how I can support Trump. Arrogant guy who says a lot of stupid stuff, but look at the alternative. 3 Quote Link to comment https://www.bigmacktrucks.com/topic/63113-hytran-in-2-stick/#findComment-454806 Share on other sites More sharing options...
