  • Methanethiol is an organosulfur compound with the chemical formula CH ₃SH. It is a colorless gas with a distinctive putrid smell. It is a natural substance found in the blood, brain and feces of animals, as well as in plant tissues. It also occurs naturally in certain foods, such as some nuts and cheese.

  • The very last thing Rob said was "Why the he'll does this gear oil smell like shit?" Lol,,, I think it's from high sulfur content which is similar to rotten eggs. It's also so you don't confuse it with motor oil because you can tell by the odor. Natural gas has Sunkist odorant added called "mercaptan" for safety reasons otherwise it's odorless and you could blow yourself up if striking a switch or match

  • Yo Rob! I've never set backlash on a diff before but I think if you just read the factory manual, they have a much easier way to do the adjustment,,, I believe it involves using a dial indicator! And or maybe some white grease or paint on the teeth

  • It might be too late to tell you now. If you're able to not destroy the old bearings, take a carbide bit to the inside bore of the bearings and you can use them as "set up" bearings. Very useful to have when setting up a diff.

  • When will this car be finished? After 1000 videos? With your time, money and resources, this project should've been done and dusted weeks ago. There is nothing wrong with taking time for a well done project. Aerodynamically, I am sorry to say, your cooling solution is an absolute mess. You have unnecessary weight beyond the front axle. You have tubes blocking a great percentage of the rads' frontal area. You have 2 heat exchangers physically conducting energy between each other. Suspension kinematics are far from ideal as well. Come on... With your time and budget, you could've done so much better. Anyway, your top speed and acceleration will suffer, particularly above 70 or 80mph. Power is not everything.

  • Peg your diff. In the land rover world we don't have the best diffs/axles😂 so we peg the diff by have a phospha-bronze Pas running on the back of the crown wheel held in place by some studs through the diff case. This stops the crown teeth walking up the pinion screw and stripping teeth. Best strength mod you can make

  • German car youtuber Philipp Kaess is using the same/ a similar diff in his rs4 limo build and he also ran into the whole driving it backwards problematic. They are now engineering a new billet housing that flips everything to drive it the right way around and use the strong side of the teeth. Might wanna get in contact with him.

    enemysfriend22enemysfriend225 kuukautta sitten
  • just as a point of reference.. if that diff is not designed to go in reverse, i would suggest you take high detailed measurements of the current ring an pinion and put that in a cad file and make a new one capable of living in reverse

  • Start saving now and you'll be able to replace the diff after it destroys itself from driving it backwards. Hypoid gearsets like the ring and pinion have an offset to compensate for the drive rotation which is now going completely ass backwards.

    Toms TechToms Tech5 kuukautta sitten
    • No, hypoid just moves the pinion below the centre-line of the crown wheel, amboid is above the centre-line. I do agree that the thrust is now on the wrong face though..

    jerry hendersonjerry henderson5 kuukautta sitten
  • Whait, this goes backwards? The normaly coasting teeth side gets load? This diff wil break sooner or later. Beacuse of the angle of the teeth there will be a shit ton of side load on the pinion, reason why you are not suposed to drag heavy loads in reverse.. Simple fix flip the casing upside down and that wil work.

  • You don’t shim under the pinion bearing like a Ford? To set pinion depth?

    Sloppy MechanicsSloppy Mechanics5 kuukautta sitten
    • @Ramjet You are correct, using the existing shims will always get you 95% close from experience

      Sloppy MechanicsSloppy Mechanics4 kuukautta sitten
    • Pinion should have a + or - number to indicate the pinion variation from “0”. +5 means the pinion is 5 thou bigger, and you need to compensate by taking 5 thou out of the shim thickness. -5 means the pinion needs 5 thou added to shim thickness. If original pinion was +5 and new is -5, the pinion variation cancels and you need no shims.

      DadsGarageDadsGarage5 kuukautta sitten
    • Shims should be between pinion gear and inner bearing. Reusing existing shims will probably get you very close to the right setup. The shimming is usually case specific, not ring and pinion specific. IE the cases and carrier have more machining error than the gears

      RamjetRamjet5 kuukautta sitten
    • I guess it could go either way. But I was going to shim the race on the pinion and save the crush sleeve for the preload without changing that depth. Honestly this is only my second rodeo 😂

      Rob DahmRob Dahm5 kuukautta sitten
  • Rob, you should add some round sump magnets to the diff that will help with the fine metal. You should also call BMW and ask it the rear lubricates in reverse some splash oiled diffs use splash and the rotation of the diff to pump oil up to the pinion bearings it would be worth a call...

  • Banks did research showing your ring and pinion could be damaged due to oil aeration by flat differential covers under large torque. If you love gear oil, keep that cover.

  • Rob I have a very important question, you said your front diff is always running in reverse because it's a diff off the rear of a bmw, but here's my question, why didn't you just flip the diff upside-down, minor mods need to be done but it's super easy and common and will lengthen the life of you're diff

  • The timing of this couldnt be awesomer. I am rebuilding my diff for my big tires offroad miata this upcoming weekend. Im upgrading the 4.1 stock rear gearset to a 5.38 Paco motorsports rear gearset. Just waiting on all the bearings to come in the mail.

    SmallTownMadnessSmallTownMadness5 kuukautta sitten
  • Given the fact that the rotation is now going to be reversed, are the pinion bearings going to be lubed correctly? There is an oil galley that the ring(in regular rotation) serves as a water-wheel and directs oil into the galley and constantly lubes the pinion bearings.

    Johnny -OJohnny -O5 kuukautta sitten
  • If you want a basically zero slip diff, I have seen a torsen diff for sale for the E36 BMW that should bolt up to the ring gear as it's a drop in replacement for the stock. Don't remember the power rating though if there even was one listed.

  • A 1000 mice power with a 5.14 7 tooth pinion diff. It will last a very short time. And drain the oil first! You shim the pinion inner bearing to raise or lower in the carrier. The crown wheel carrier usually comes in various offsets to put it closer to the smaller pinion. And then shim or adjust to do the final adjustment. Though as you say the diff is running in reverse so you need a front diff with the teeth cut the right direction.
