Always enjoy your diff videos. I have a question that no one has answered for me. When checking gear patterns, I understand checking the drive side with pressure on the ring gear. However, when checking the coast pattern, shouldn't the pressure be put on the pinion and turn the ring gear since during coast, it is the ring gear that is supplying the driving force?
@@skutahuniai4830 The driving force always comes from the pinion no matter which way the ring gear is turning. The only exception would be coasting to a stop and letting the drivetrain slow you down. Don't confuse the coast side as not doing any work. On a low pinion front axle, the coast side of the gears is what makes it go forward.
@@TheBFHGarage I understand that the pinion is supplying the drive force both forward and reverse. However, the only time the coast side of the tooth(hence the name "coast") sees any force IS when you are coasting to a stop. All other times, the drive side of the tooth is seeing the force. In that case, as I said in my first post, it is the RING gear that is supplying the force or "drive" and the "holdback pressure" should be applied to the pinion.
Let's take it a step further. Because the coast side is called the "coast" does it mean that it only sees force when coasting down the road. Take a high pinion rear axle for example and it will drive down the road using the coast side of the gears. Coast doesn't mean it only operates when coasting.
@@TheBFHGarage It is my understanding that the reason for proper gear setup is to eliminate gear noise and to guard against premature gear failure. I don't think that the minor amount of time a diff spends in reverse is going to have any significant role in either of these when going in reverse. I'd be more inclined to think that it is more important to eliminate gear noise when "coasting". As for your attention to diffs using the coast side for driving force, that is not the case here. I would assume that the same condition would apply - pressure on the ring when driving, pressure on the pinion when coasting. Reverse is irrelevant either way.
That was a great video, thank you sir 👍😁
Very nice!
That looks very much like the Ineos Grenadier (or maybe the other way around).

@skutahuniai4830 what about reverse?

Of course that is not a Jeep, it is a british attempt to copy the Jeep.
