Great info! I’ve found Optilube ZDDP to work good for a zinc additive in my trucks. I also use the Optilube XPD to hopefully protect and give additional lubricant to the entire fuel system.
Thanks for this great information. Definitely will be trying some of these formulas. Especially the pink antifreeze. Thanks for all you do for us Garrett!!
Nice to see videos from Korea !
I am running a 15w-50 grade with both zinc and phosphorus blend in my truck which is a 1953 REO M-Series gasser... For the transmission t-case and axles I been doing the 80w-140 long life gear oil.. the brand of both are AMSOIL full synthetic fluids.
Keep up the videos!!!
Good video. Thanks
Good stuff Thanks
I'm liking a SAE 50 Mobil Delvac synthetic fluid designed for manual transmissions. Harder to find but works very well in these transmissions. I was only able to find it locally because I live by a Summit Racing. I need to try the big truck places because I use Something similar on Kenworth trucks at work.
On my 72 M35A2 I'm running spin on filters with Lucas 15W&40 oil and 2 Quarts of Lucas oil stabilizer
"cavitation" is the word you were looking for regarding vibration caused corrosion I think.
I believe the effect you were mentioning around the 21 minute mark is cavitation.
Would you recommend running a coolant filter with the ASE stuff, or any other antifreeze?
So I've been wondering something ever since I serviced my truck. I wonder if you could put a modern heavy truck SAE 50 synthetic transmission oil in the deuce Spicer trans. It's safe for brass eaton transmissions have brass in the syncros for the range selector etc, its literally made to be in a transmission, its thinner than 90w gl1 but a bit thicker than ND 30 engine oil and it has all the extreme pressure additive packages. Right now I put ND 30 and 2 quarts of lucas stabilizer in my Spicer and it shifted like butter compared to when it had the original gl1 90 I drained out. Give me your thoughts I'm tempted to try the heavy truck sae 50 synthetic trans lube that's what we run in the heavy trucks at work with eaton transmissions. If you look up Lucas makes a sae 50 synthetic fluid for heavy trucks and the description for the fluid sounds like everything you would want for the deuce trans.
@@tacticalrepair sounds like next service I know what I'll be putting in. I was planning on it until I seen that nobody does it I was confused on that but it must be that nobody knows about it or just puts in what Spicer recommended back in the 60s like I did. Another great option would be Caterpillar TDTO (transmission drive train oil) it comes in a variety of different viscosities from 10w, 30w, 50w, multi grade. It's made for gears and stuff pretty much every Caterpillar transmission, differential, gear box or planetary final drive uses that stuff and 30w is typically the all around average temperature range for every application.
Regular. Lucas oil stabilizer has no real zinc just thick oil
Shell Rottela has 1200 ppm zinc. Which is plenty by itself for zinc. Most S oils today are less then 300 ppm zinc. To much zinc in oil can cause problems such as sludge and clumping
How much do you want for the power steering kit
That's one of the only things that suck about a duce is no power steering
