Nope. I have no idea why anyone would run seals and grease. Oil is much better than grease for hubs for many reasons.

Care to elaborate? I've been running grease simply because it doesn't make a mess when you pull a hub off. If there is enough benefit I would be willing to let them get oily.

I'll throw in my .02$ on this one as I've had my hands full developing the B14R lately anyways. Here is a pretty good comparison

http://www.machinerylubrication.com/Read/923/grease-oil

Both have pros and cons as you can see. Grease has been used extensively in wheel bearings for decades and oil has been as well. As much maintenance as a race car gets anyways I'd say that both are equally as good and is as much mechanic's preference over anything.

I will agree that oil is not neccessary, except to cool for long hauls. But, if its cooling the ring and pinion as well, then go with it! Plus grease does not circulate, so any trapped debris will stay, and get fed back in, as oil will move weight/debris away, allowing the magnets to trap particles.

Better lubrication and pulls heat from the bearings for starters. I can see using grease for crawling and it being easier to deal with, for fixes and for prep and inspection. But IMO oil is better for going fast and having it last.
Your rear brakes alone build huge heat that transfers to the hub, when hooking it through the desert, which is what I'm guessing the new car is for...

Somebody has to give you some VORRA competition...

I hadn't thought about it carrying brake heat away. I'll give it some thought. It would be nice to only have to make one set of axle seals.

which seal would one run to minimize a leak at the hub if one were to fill the housing with oil. a standard dana part type seal at the back of the hub would leak like crazy wouldn't it?

and then to hijak....

and if all this filled-up-with-oil housing stuff is ok then is there any reason i cant just fill my ifs dutchman 9" housing to the brim to account for the flipped 9 im going to run up front? vs needing to run a pump or "scoop" type arrangement to keep it loobed?

A True Hi 9 takes a lot of oil in the front. It doesn't fill it up, but it does go up past the axle centerline.

The 9" pumps are pretty trick and not too spendy and it puts the oil right where you need it. As a plus you could run it to a cooler and then back to the gears.

i dont like the hp robbing thing. i like the internal pump. just set it and forget it. (and hope its working)

what about he hub seal thing. I know that this application has proam hubs but wouldn't a normal seal on a 14b/dana 60 etc leak if you overfilled the housing with oil instead of using grease?

14FF, D60FF, and most other full floating axle hubs use oil to lube the bearings not grease.

Is there room to run that 9" pump on a 14FF if you broached the pinion? The pinion isn't that low and the carrier is bigger.

You will also need to have the head of the pinion broached and the case machined to accept the pump. Mark Williams does it. May be less of a headache to send your case and pinion out vs. taking your machines down for modding one case.

Doubt it will fit the 14 bolt straight up but with a few mods...

A bit of a teaser... working with Jason @ Tubeworks right now to incorporate some of his recommendations, then it's time for production.

That's pretty bad ass. The only thing i dont like is the countersunk Allen head bolts. Judging from the bottom of our 9" those pockets that the heads are in would quickly be beaten down around the bolt head, and the hex's would also be thrashed, making removal a major pain in the ass. I'd much rather see regular machined faces for standard bolts.

Back when we were running 60's with crane covers we ended up replacing all the allen head bolts they supplied for just this reason. Every time we needed to pull the cover we'd end up welding nuts to the head of the bolts to get them out.

Appreciate the feedback, Jason actually mentioned this same thing to us a few days about and haven't changed it yet.

IMO the skid still looks like crap, but we'll have something nice and pretty for final production.

Awesome to see the progress!

I think a fitting name would be the BA14... Ballistic Apex 14 bolt? or Bad Ass 14 bolt!

Any thoughts to mirror the pinion over the centerline and have high pinion gears cut to fill that area of the market?

I've had HP gears quoted out and I'm not quite ready (or able) to spend that kind of $$$ at this point, but I've definately thought about it. Maybe offer one or two common ratios just to start with.


Material is A356.

Jeff,

How about something like the skid I built for my Jeepspeed. You could even make the front stick out more to protect the pinion yoke. (I'm not a big fan of the pinion guards as I think they collect rocks in the desert that can damage the shaft/yoke, but I see the use/application for the rock crawlers.)
