It's not one of those hyper detailed hour long videos!" 😂 Keep up the good work man! This is literally my favorite channel by far because of how dedicated you are to doing things CORRECTLY (unlike 95% of the other automotive YT channels) and the attention to detail you have, along with ACTUALLY explaining it all makes my brain AND heart happy.

[@802Garage]

Rob, it's amazing to me that you have an entire CNC machine and not pilot bearing puller. Exciting stuff. :D

[@matthewhall9530]

Don’t know if the manufacturer says to offset them but usually in multi-plate clutches it’s a good idea to line the plates up as closely as you can so the intermediate plate or plates don’t distort and cause a slip issue. I know in heavy duty trucks the pads of friction material on a puck style disc need to be aligned roughly with each other. Depending on the alignment of the splines to the disc they might not fully align but the lower the overhang between the discs the better.

[@logancannan2040]

[@jamest5149]

A suggestion… Machine a o-ring channel in the oil pan on the CNC and use some o-ring stock… much better solution than sealer on flat surface for sealing.

[@michaelgutierrez6564]

You can pack the pilot bearing cavity with grease then use a rod the same diameter as the output shaft and hit it with a hammer. That will push the bearing out.

Level of detail you put into the builds is top tier. I'm really mind blown by the fact you chose to do this deep of a dive into the rotary motors . I can't think of another power plant that needs it more than the rotary. I'm not a huge fan of rotary wankles , more of a vk56 fan , but your expertise makes this a very very pleasurable channel .

[@Kenji1685]

[@MADDLADO1]

That's just unimaginable that all that hp goes through that little shaft, and doesn't just twist apart. This is truly one of the sweetest cars I've ever seen.

[@Stereomoo]

It does have a mechanical advantage compared to the axles, if there's a 3.5 final gear and 2.5 first gear, the axles get a total of nearly 9 times as much torque (2.2 each for an even split, probably as much as 4x as much torque on the rears)

[@michaelmayer2430]

Probably already been said but use grease instead of bread. I have had a lot of success by packing the bearing full of white grease and then finding a punch or extension thats close to the right size, then wrapping it in electrical tape until its a tight fit in the bearing. couple taps with a hammer and the bearing pops right out. works shockingly well.

[@urdoneson46]

[@freekcorsa]

Clutch: in my opinion, the Clutch plates should be aligned to each other. Now the pressure of one plate is not pressing straight onto te next plate. This combined with temperatures can cause the floater plates to warp.

[@jadeynolah5832]

I want to see the 4 rotor enter grid life unlimited class!!

[@saganworshipper6062]

For me, this is the second most epic thing that happened on Earth today, after TB retiring! When you were putting the thread lock on I heard Derek from Vice Grip Garage in my head saying "that's way too much.....perfect!". I can't even imagine how this must feel for you Rob! This is a true Beauty and a Beast! All the hours and hours are paying off. I can't wait to see you blow the Hoonicorn's doors off! Be safe and congratulations man! What an accomplishment. We all know how hard you worked for this. The way you thought of making every aspect as bulletproof as can be really brings a smile to my face. With that much horsepower you'll know real quick if any stone was left unturned, but I got my money on Rob this time. I think it's going to hold together. Amazing!

[@st3althyone]

Yeah, the rematch will be something to behold.

[@phatmanplayz9561]

I have a small suggestion... when I was doing my training as a mechanic I was taught that when doing up a sealing component especially something such as the oil pan in this case you should tighten/torque from the centre towards the ends so as to avoid any bowing or kinks in the sealing surface. But loving the work Rob love seeing the progress in your knowledge translate into your cars.... absolutely epic.

[@benoitlaurin979]

Wait... You said the engine is in and not coming back out but... I don't see a firewall. You'll work around everything? That will be a pain in the butt no? On another note, this is just awesome!

[@VishnuRajam4x4]

[@jonholaday2733]

I understand I'm late to the comment section, but there's a specific tool made for pulling pilot bearings and is super handy! Literally takes longer to remove the tool from the package than to actually pull out the bearing with it!

[@alexk.8715]

What I usually do for silicone gaskets is to pre tighten the oil pan bolts carefully to a point the silicone gets visible from the outside. Then let it cure completely before tightening to spec torque. That way you leave enough material between the mating surfaces to adhere and seal properly. You just don’t want to squeeze it all out since you can’t wipe the excess material off on the pan’s inside and silicone in your oil pump can’t be good for sure.

[@mattlanthier4153]

Literally perfect timing for this video back to back goodness from all my favorite car guys

[@c_solly5892]

It's wild how that tiny little motor can make soo much power

[@Superdupersupersuped]

Dude pack it with grease, use a tap to tap the bushing, then after taping the bushing run a big ass bolt in there, the hydraulic action from the grease (or bread whatever wet towel combo you use) will put the bearing out, you won’t thread into anything but the bushing , and the bushing comes right out. Even if you run into the e shaft or crankshaft it’s gonna just push out, if you use towels or bread you won’t have to worry about that, but it works well enough not to have to be nervous about that. They’re usually made of brass (the bushing) so it’s easy to tap. Probably should use at the very least torque sticks with that heavy of an impact as well. Flywheel bolts usually don’t need 200 ft lbs lol. Love the vids keep at it , sick build :))

[@13geeky]

Mr. Rotary. A job well done. Such a beautiful motor ❤

[@nicolascrescimone]

You should build some sort of exoskeleton with a thicker oil pan and bigger bolts to prevent any torquing of the motor, or like a 2" billet aluminum plate sandwiched in between the engine and oil pan with m10 bolts. Just an idea

[@aerialimagesbydoug5733]

to get the bearing out I fill the hole with a crushed bar of soap or thick grease, find a socket that , just fits in the bearing hole reverse it put an extension in the reversed socket hit it with a soft blow hammer. it will pressure the bearing out of place.

That 1 small piece can handle the load since it's not amplified by the gear reduction. Just like monster trucks run pinion breaks and they work awesome since it's pre gear reduction at the ring & pinion.

[@lowtus7]

A tip is to put the thread lock into the female threads of the crank, not on the bolts, putting it on the bolts means some of it can make its way between the flywheel and the crank when you insert them, causing it not to seat 100% flush, depends how picky you are of coarse, lol. Just good practice.

Hey Rob, you could get a big o ring and machine a nice groove with someone light pinch points so it stays in place. You have the technology.

[@tylermarini9683]

Brooo anyone else notice Dahm gettin them gains 💪

[@aserta]

Considering how the pan works, i would find it genuinely worth my time to machine the entire bottom of the engine + pan to create a groove. TWO major selling points for this: in operation, the pan is under vacuum, which means that if you machine a tolerance into this affair where by vacuum it seals (like in the SR-71) you don't need sealant (ok, just enough to dismiss oil leaking out when it sits around) and two, by giving the pan plate a groove to bite into the engine, it will dismiss the studs as structure and bypass it directly into itself, making the whole affair Nth times more rigid. It would also be trivial to do this. You only need a jig and a router with a carbide bit, that's it.

[@Njabzillah]

I think the pilot bearing is known as a white metal bearing. The ones I have worked with were on big compressors with really small tolerances but i cannot recall if they need to be greased on installation or not. But that bearing should last the lifetime of the car. Ask an HVAC/Ref Artisan (who deals with compressors) about WMBs so that if/when you need to replace it you do it properly the next time

The trans input shaft doesn't necessarily see "all the torque", peak torque is after the diff. It sees roughly the same power, put torque is much higher after the gear reduction of the trans and differential

[@gabrielenitti3243]
