Observing frozen oil under a transparent differential cover

[@Taydrum]

If anyone is interested in observing the oil in differential while running further, I recommend you check out Gale Banks videos on differential oiling using different diff. covers. He shows how switching to a modified differential cover can change how it gets oiled good or bad

[@thelol1759]

Banks has a great set of videos for sure. It’s interesting because this video is such a great example of how terrible aeration is for oil.

[@5.43v]

@@the_kombinator you definitely could with a manual but it'd be a little messy

[@mr_nice.]

@@ВадимВадимович-ь6т ....I would assume it depends on where the differential is. If it's located next to the gearbox, as in modern front wheel drive cars, which is right next to the engine, inside the warm engine bay, it picks up heat from the engine too, (apart from the internal heat), and it deffinately gets up to temperature. You may need to drive it for a while, to warm up, but eventualy it reaches some temperature. It may or may NOT be the "opeating" temp, but it will get warm enough to flow nicely as it is designed. Or at least flow as we see it in room temperature. If the diff is away from the gearbox, like the one in the video, I have my doubts. It is very well cooled all the way around, and you may need to run it for longer, or maybe with load, to warm it up enough to reach the flow of room temperature.

The spec for the amount of gear oil was wrong. The plug level is correct. If you dont get the level to that height the inboard and outboard axle bearings are not recieving any lubrication. The level should always be just above the bottom of the axle tubes. Regardless of the axle.

[@chrisking4616]

Yeah the capacity of the diff was increased as the vacuum formed cover was made over the exterior of the original, yet the screw holes were in the same location. Only adds a millimetre or two here and there but it all adds up when it comes to volume.

[@robc7812]

was looking for this comment

[@xidarian]

The repair book volume is for draining through a plug and changing which leaves some residual behind. They definitely should have filled it all the way.

[@jeremypike9153]

I was wondering why they didn't vacuum form the inside of the differential pan. Probably harder to get all the air out on the inside then it was on the outside.

[@chrisking4616]

Vacuum forming the inside probably would have done the opposite; made the volume smaller slightly and raising the oil level too high. Ultimately unless you took a mould of the original and then cast a clear replacement from the mould, it’s always going to be slightly different. Easiest fix would have been to just follow the general rule and fill it to the plug regardless of how much you have to put in.

[@slob259]

The cover is shaped so that the oil is like a hose to the front pinion bearing, that's why those big square diff covers are junk, they just make a big foaming mess and stop oil flow to front pinion.

[@dalehatton6965]

That's why the shape of your cover is essential to getting correct lubrication of the differential, after market bling covers can cause diff failures.

[@joebledsoe257]

Gale Banks did this on his KZbin page sometime back, except the cold show. Oil never really freezes, but it does get very, very, very, thick at extreme cold. As thick as it reguarly is when warm it adheres well enough to the stuff when not moving to lubricate it for a while when operating cold. Look at how much is on the sides of the housing when the cover was off. It will warm up shortly when operating and continue doing its job. Following what Banks showed about aftermarket covers, I took mine off and fabricated a channel of aluminum sheet metal to direct the lube directly onto the ring gear and the side splash onto the spiders. The hardest part of that process was deciding where to put the mounting holes for the channel into the diff cover. I used 2 stainless steel studs in the cover and attached the channel with nuts and lock washers using spacers to locate it close to the ring gear. Thanks for the video that was nice.

Well over ten years ago there were polycarbonate diff covers available for dana 30, 44, and 60 (which also fits 70) axles. They discontinued as far as I know from a lack of interest.

[@TsunauticusIV]

Banks has a much better clear diff video series. The added a light inside the diff so we could see better.

The reason the amount of oil was lower is that you've cast the cover on the outside of the real one. So the internal volume increased by the volume the walls of the metal cover would have taken up.

I have a rear end tail, or tale. I had a 99 Rodeo and the pinon leaked and the right wheel bearing leaked too. I had not been checking the level but found out it was very low. It was cold, cold for here one morning, about +15 to 20 deg F and after driving for about 5 miles the rear end started howling and guess what oil was in it was sticking to the case starving the gears. The closest place was Walmart about 4 miles away. Pulled in there and they filled the diff but it stilled howled about the same. Got a rear end from the salvage for $250 and installed it by my self in a day. No more leaks and the rear end was quite. For me it turned out OK and learned a lesson.

[@prjndigo]

The plug fill/drain on the differential housing is located at the height you must not fill above or the fluid will flow out the axles and mess up those greased bearings and the brakes. So the fill amount is actually about 1.5 quarts / 1.4 liters at the plug hole maximum. Banks did a video of the development process and had clear caps of different after-market designs and is worth watching.

[@xeigen2]

The volume inside the diff cover is going to be higher because it was formed around the outside of the original. It will need more oil to reach the correct level.

[@adamhbiggs]

That's what I came here to write.

[@sonicdewd]

Running the numbers using volume of a sphere is v = 4/3 x pi x r^3: Assuming differential cover approximates the shape of a 1 foot diameter ball (it roughly does), the volume of this ball minus the volume of a slightly smaller ball inside of the first ball will give the volume trapped between the balls. The slightly smaller ball will be smaller by as much as the thickness of the metal in the differential cover. So, the gauge steel used for differential covers is about 14 gauge (about 1\16 inch) thickness, so this converts to 1/192 ft. If the first ball has an r1=0.5 foot, and the second ball has an r2=0.5-(1/192)=0.49479166 ft., finding the volumes is just using the above formula for the two balls, and then v1 -- v2 will give the volume, as mentioned before, of the space between ball 1 and ball 2. Chop that result into a third of it (only about a third of the ball will rest in the differential cover) and you end up, after converting empirical units (freedom measurements) to liters, you'll get 0.152835 liters of additional oil needed. That's like a spitball's worth, albeit a big, sloshy goober type that would sound like "THUNNNNNG" in a spittoon rather than a "ping". However, this is even wrong - the plastic was shrunk onto the outside of the flange as well as the roundout. That means that the plastic flange will end up exactly where the metal one once was (that is, bolted up against the cast iron case), which means the plastic one emulated the metal one almost perfectly in almost every way. This means that the overall volume remains almost unchanged. One wouldn't even be able to measure any change at all.

[@austyndrums1993]

Just so everyone is clear. Frozen oil isn't usually something one needs to worry about. Most civilization exists in warmer climates.

[@SuperMegaValy]

You said it yourself, so put some soarcream in that diff and see what happens.

[@zeropointzero]

Diff oil level should always be just above the bottom of the axle tubes. After you washed the diff, everything was dry. Then it picked up some oil and the level was low again. Diff oil lubricates the axle bearings at the wheel end too, and if it can't make it down the tube, bad shit starts to happen.

[@johnnyg632]

It seems they could engineer the cover to help direct more oil out and toward the bearings when it's running at cold temperatures with thick oil.

[@ldnwholesale8552]

Oil transmits itself where required. The star gears do not require a lot, the side bearings require even less. Axle bearings get it as it wraps around the shafts to the bearing. In motorsport applications however some diffs require baffles in the axle tubes as all the oil goes up the tubes with G Forces. Then wants to stay there in turn causing axle seals to leak,, and starving the ring and pin of oil,, then they fail. These little Salisbury diffs are quite good standard in that respects. Try this same test again with synthetic oil. It flows far better cold. And takes a lot of heat out of the oil also,

[@shadowfox-nf6zi]

It would be very interesting to see these transparent-case comparisons with the proper fluids for the application, rather than mineral oil. Show us 0W20 vs 10W40 at -10C in an engine, and proper viscosities of gear oil in the diff.

[@ronniemaeker9102]

How about put some small "baffles" on the cover to direct the oil? Open a "window" in the axle housing to see what the oil does for the outside bearings? Put clinging and climbing oil, similar to Lucas to replace, or supplement the regular oil? The old "trick" for used cars: STP additive?

This is more Dr. Doom stuff. The mechanical forces the oil subjected to will make it warm up as soon as you start moving. Check the specifications of the product you are using and the specification of the production itself. If you can use a certain weight of gear oil down to a certain temperature, all you need to do is turn the key and start driving. Common sense says, in very cold weather, drive as moderately as you can when you start out to give everything a chance to warm up. Most people don't live in a place where it ever gets below -5F (-20C) overnight.
