Front Diff Oil

[SkyPup]

The one large oil fill bolt (on top of the axle housing) is where to add oil for the entire front axle, it will drain down into both bevel gear housings at each wheel. We always use straight UDT in them as well.

The main difference between a gear lube and a tractor fluid is the hp capabilities. Gear Lubes are designed with high pressure additives to cushion the gear to gear contact. A tractor fluid (HyTran, HyGard, etc.) may not have the characteristics necessary. I am a former Case-IH, Deutz Allis parts manager and sell Lubrication Engineers line of enhanced lubricants. look on my companies website @ homepage for information. <font color="blue"> </font> <font color="blue"> </font>

Hytran, hyguard, etc.. ( jd 303 NH 134d ) are all rated as final drive lubricants.. that leads me to believe the addative package handles ep duties... Nh has been spec'ing it's 134 fluid ( in various forms ) for years for even the large ag tractores that have common sumps for hyds and final drives.

JD has been doing the same.. as well as many foreign manufacturers.

If UDT,and super UDT is good enough for the rear differential with all it's stresses,then it certainly can handle the front differential.
