Hi Bob,
Just finished a total re build on my 1955 Willys Cj3b w/F134 cu.in. 4 cyl."Hurricane" F-head flat tappet engine (w/a raging 75hp), a Warner T-90 3-speed Synchromesh trans., Transfer case: Spicer 18, 2 speed, Front axle: Dana/Spicer 25, Rear axle:Dana/Spicer 44, Semi-floating hypoid.
The origional manual lists lubricans from the early 50s.
Any advice for what to use thats available now would be appreciated.
Thanks Jax

I agree with daves87rs in his agreement with 94supraonchrome. Where you live I would kinda, sorta, maybe favor the VR1 40.

VR1 it is then1!!

SpitfirS: the original recommended lubricants were:
Motor- just "motor oil"
Trans/Trnsfr-GL4
F&R axle/differentials-MIL-L-2105B

Thanks, Jax

Greetings! Nice to have another Jeep guy here. I have a 1959 CJ5 with the same drivetrain. I run Delo SAE30 or any conventional 10w40. Actually, it currently has Supertech 10w30 while the body is off for repair. F heads are pretty indestructable. You could run just about any oil in it without problems.

Also, I run Coastal 80W90 gear oil in the transmission/tcase/axles.

Well, they can't be too picky then. You could probaby run used oil in there with no problems...

I'd consider using HDEO (diesel) such as Rotella 10w30 in cooler months, and 15w40 in summer...
 
HDEOs are very reasonable and very good. The 5 qt bottle at Walmart like Rotella or Shell would be my choice, as the 15-40 would seem perfect for that engine.

I would run a 10w40 or 15w40 or 20w50 depending on climate and add some ZDDP additive to it to decrease the stress on the flat tappets, although these are Indestructable engines... But you know... We are crazy here for oil!

The F head has the intake valves in the head and exhaust valves in the block. Kind of F'd up.

Yeah,
FYI, Kind of an evolutionary "missing Link". Wartime MB/GPW & M38 jeeps
34.gif
& the postwar civilian models CJ-2A & CJ-3A, had limited horsepower 60+-hp w/the 4cyl L-head (flat head)"Go-Devil" engine. Willys began putting the new F-head "Hurricane" engine in its larger vehicles in 1949,its intake valves were in the head rather than the block, allowing them to be larger.The increase was about 10-15hp "WOW" shes at warp speed at 60mph in OD but small-N-she'll crawl up anything w/her 5:38 rear end

.
The first Jeep w/the engine was the military M38A1 in 1951 w/the new "round-fender" body, it was used for most Jeeps for the next five decades F'n reliable...wot
LOL.gif
. The 1st Universal Jeep w/a "Hurricane" engine was the new "high-hood" flat fender CJ-3B in 1952; it stayed in production well into the sixties as a shorter-wheelbase option.
 
Boy you got that right Steve,
You must own a jeep??
I have a "hot rod" ford truck when the need for speed hits me,hardly use it now, but the Willys sure gives me a different perspective. She gives me time...to take my time. Like "back in the day" you can actually look around when you drive somewhere and I'm usually on a two lane road when shes on the road but she perfers slow in low asross rocky dirt tracks to nowhere. Keeps things simple and sane it todays world.

They didn't come with OD. You had to buy an aftermarket unit (Warn) that bolts onto the PTO port of the Spicer 18 case. Without it, you'd be lucky to hit 50mph.

The older Jeeps did OK, but even with the 5.38's, the poopty 2.99 first gear in the T90 and marginal 2.46:1 low range in the Spicer 18 only gave it a 39.57:1 crawl ratio. By comparison, a new Rubicon's low range is 73:1. My rig is 103:1.

Actually, it stayed in production until very recently (IIRC, 2001-2002) by Mahindra in India. You could get it with a Peugeot diesel engine too.
 
You are quite right Zaedock,
The OD is an aftermarket Warn that was on it when I got it from my uncle, the 1st owner. I'vekept it pretty much stock The only practical modification option for my Willys would be a T98a w/a"granny gear" 6.34. The advantage is the 1st gear. Overall gearing of the T-98 in 1st gear, w/the transfer case in high range, is roughly equivalent to 1st gear of a T-90a w/the transfer case in low range. Putting the transfer case in low range and the T-98 in 1st gear gives one a 'crawling compound low' that is good for going crawling over a steep difficult terrain.
If you stall going uphill, you can put it in 1st gear low range, leave it in gear, work the starter. The gearing is low enough to start the engine and get going again without any sudden jerks or strains.
My Old Willys is pretty much a frame off,mainly stock restoration. I've rebuilt the engine,trans,trnsfr, axels,steering and the origional with factory Powr-Loc rear differential.Parts have been quite an adventure to find but through the internet I've found them all over the country. Modifications,mostly updates to safer stuff, have been: disk brakes up front,11" drum in the rear,(the standars 9" scarred the daylights out of me one day on a steep hill),Alcan springs n H shackels,12v conversion with a 1wire alternator fm 6v and an M38 open side type "summer top" and bows. She's great for coastal fishing, bird hunting on the mountain and getting lost and back sometimes.
Sounds like you have quite a nice YJ rig Rock Crawler. 1O3:1 is very low. Do you go to those crawls in the Mass.or the SW US?? Saw some places in the Utah wilderness that looked like neat places to go trailing.
I thought Mahindra in India might stil be in production.Sorry to hear it isn't.
Keep jeepin, Jax
 
The perfect oil would be a 10w40 Mystik...or if you must run 15w40 then use any of the diesel oils (rotella, delo, valvoline blue, etc.)

But Mystik has the good additive, it is a syn-blend, and is a non-High Mileage oil so that is a tempting choice if it were me.
