Bolting The Evo Cases Together Part 2

Flywheels Are In! Bolting the right Case On To The Left Case

[@UncleBogator]

I’ve watched all 23 videos in this playlist today. Picked up my first evo in May and it’s giving me trouble. Wanted to watch all of this to learn some things. Thanks for putting it all together. I ended on this video cause i started with the oil pump one. That’s what I’m currently troubleshooting

Mike, From what I understand, the Torrington/Timken was present on the lefty side on the Twin Cams up and through the ’02 model year, at least on the Softails. Downhill from there as the bean-counters took their scalpels to the marque : / Thank you again for this phenomenal Evo series; what spectacular, in-depth tutorials and showcasing of expertise. So valuable. In fact, INvaluable. From over on the coast ~ Ride Forever! 🦅

[@pacificmike9501]

There is an adaptor kit of sorts to switch the later flywheel assys. over to Timkens on the sprocket shaft side. If Harley does something I don't like, someone usually has a solution.

[@MidnightExpressMC]

@@pacificmike9501 Yes, that is correct. What I’m saying, though, is that 1999 through 2002 where Timkens from the factory on those Twin Cammers, not ended with the Evo run as you stated. Also, it’s a bit of a cumbersome ordeal to take the entire engine out and split the cases to do that retrofit/conversion if not an OEM feature 😃

Mike, hello. Your videos are some of the most down to earth. I wanted to ask about the lapping of the pinion bushing . The math in sizing the size bearing to the now lapped bushing ID. That is a really cool part.Your fans are gear heads.Thanks,Bear.

[@pacificmike9501]

You know, the math is in the book. And it's great, difficult at best. The way we do it today is with Evolution bearings. A little difficult because you need several bearings to try and feel for fit. All of the precision fits are great. But the final fits are by feel.

Hey mike , I’ve probably watched this evo build a hundred times.. I was wondering if one day you could do an in depth video of crank end play.. something that I believe is overlooked so many times in build videos and it is so very important.. aloha from Hilo Hawaii 🤙🏽

[@pacificmike9501]

Crank endplay is something you always check, but on this "late model" stuff it's pretty much already handled by the "Timken" set on the left side. Most of us buy those bearings as a "matched" set. That's two bearings, two races, an inner shim and an outer shim. This sets it. You check it and your good to go. The bearing on the right side doesn't need the endplay set because the left side is controlling it. Realize this setup is used from 1955-2002. Aloha.

Sure. We did show lapping it. This thing was in bad shape and to get it trued up, the bushing was too damaged by the last rebuild. Sorry, but replacing the bushing is not fun and I did not turn the camera on for it. However, all went well. It amounts to measuring after that. Then it is a "feel" thing. Measure and remeasure over and over. Thank you.

Hey Mike. I'm watching through your videos one by one since I got my 1980 FLH. It's fantastic for us that you and your crew is putting this content up for us to see. I have a question though, have you ever bothered applying Glyptal on the crankcase? I have seen some do it, but is that for special cases or just a matter of taste?

Not something I've ever dealt with.

[@alstone5257]

Mike another job well done. I always learn from you, THANKS FOR SHARING !! So how did you strip the pant off, and what did you use to do them as the cases look real good and have the factory new color as well ?

[@pacificmike9501]

Paint remover and scotchbrite. Unbelievable amounts of nasty hard work.

[@dilo777]

quick question. I have a 58 pan with a set of Delkron cases.....if the cases started leaking(they aren't but I thought of this while watching) is it possible to lap the cases and reseal without removing the flywheels? Also I'm the guy who was lookng for someone to drill and tap my heads for outside oilers, I did it myself and it turned out great! Thank you for your videos and sharing your knowledge!

[@pacificmike9501]

That's very cool. However, lapping the cases is done with the motor diassembled. Once the cases are split, main bearings should be replaced and refitted. Reusing the left side is often done, although I normally replace them if I've gone that far, and the right side race is normally lapped and new bearings fitted. I'm not saying skipping it can't be done, but I can't recommend it.

[@pacificmike9501]

Yes. Those flywheels should interchange. My idea is always to use better parts in Evos and that would include those flywheels. And a five piece crank makes me happy. Take care. I hope your Magnum 45 stayed together longer than the one we built in Long Beach in about 1981.

[@roberth2836]

Can you tell us , What number of "three bond" sealant are you using to seal the crank cases.

[@pacificmike9501]

It is 1211, but I've successfully used Yamabond and others.

[@josephhovanec1501]

I like aluminum cases too. How did you get them so clean and shiny ? Mine are dull and oxidized and would love to know what chemical to use to brighten them up.

[@pacificmike9501]

I did this thing with scotchbrite and paint remover. Maybe it's brighter because the cases were under paint since new. I usually try stuff until it looks like I want. It seems to vary from what the cases have been subjected to.

[@tonopahbarry]

Aluminum will begin to oxidize instantly on contact with the air. That thin layer (measured in .00x in.) of oxidation protects the rest of the piece. To prevent it you will have to go beyond polish and apply a coating.

[@markjackson8302]

Just wondering, wouldn't lock tight be a good practice for case bolts?

[@pacificmike9501]

The specs are in the manual. That's something I don't deviate from. I want the tension on the fasteners to be as the factory intended. I want the threads fresh and clean. Just my opinion.

[@johnnysechrist6313]

Mike, did you true the crank and the rods? Balance rods?

[@pacificmike9501]

The flywheel assembly was a "known good" unit and didn't need rebuilding. If building a fresh assembly, everything would have been '"rebalanced." Checked for "true" and it was.

[@michaelstrafello8025]

I have an 95 evo flhr that i spent ridiculous amount of of money to get rebuilt first problem was the oil leak from the oil galley just behind the front lifter block i sealed it with jb weld and it stopped then i got to ride 1/2 season when the oil light started coming on i was 20 mi from my house it only came on at idle so i figured i could get home as long as i didn't idle it too long i was wrong i tried to disassemble it and i stopped when I found more case cracks around the studs can 1 side of a case be replaced,

[@pacificmike9501]

Wow. Sorry to hear this stuff. One side can be replaced, but, it needs to be matched up by a competent motor builder. Consider a complete new motor. It may be the best and least expensive way to go.

[@brianmullen56]

Hello my question is when lapping the valves and cases do you need to re-clean everything again or just wipe away with a rag?

[@pacificmike9501]

Wiping it thoroughly, is very important. A quick wash with alcohol or solvent and an air hose helps too. Just be sure the guide are super clean and oiled.

Harley Davidson proper year and model service and parts manuals are the best. They are expensive, but well worth the money. Late and early Evos have subtle differences, as do late and early Pans, Shovels, and so on. That's why it is so important to be model and year specific with your books.

[@marshfield01]

@@bigrednick100 Youre thinking of the green package permatex#64000. He asked about "loctite". Not the same shit. green 290 is for pre assembled fasteners. i.e bolts you already put together and torqued dry. It wicks up the threads secures fasteners. Its temperature range is from -60 to 300f, which fits well with engine operating temperatures. On a half inch bolt, its yield strength is 80 in/lb, which my five year old could break loose without heat. I even use it on brass screws like the carb adjustment. I also use it on aircraft panels, covers, and carbs, when I fix airplanes. That someone is you.

[@joerectifier]

I am reviewing this again since I will be doing these steps this weekend. I have one question - and it comes from watching engine factory videos from Milwaukee and Germany- rather than painting on the liquid gasket/adhesive on both sides of the cases, how do you feel about just pushing out a roughy 1/8” bead on one side of the case and then pressing together and the bead spreads thru the interface? What is the downside? I am just curious.

[@hardtailsuicidaljockey6827]

So Mike what is your favorite engine? I love the knuckles but as far as being reliable and running strong I pick the 92-99 evolution.

[@pacificmike9501]

No doubt about it. Evo motors are great. They last a long time and work well. Shovelheads run like only a Shovelhead can. They sound, feel, and smell like Shovelheads. Awesome! Now, Panheads are from another time and were designed to run on those new "cross-country" Highways. They just run down the road so smooth for days and nights on end. Great sound and feel. But sometimes, one needs a real thrill. Not necessarily for practical purposes. Maybe to relive the past, maybe because they feel like they're flying, maybe, one craves that magical sound. I don't think anything else supplies the kind of rush that comes from a "Hot Rod Knuckle."

[@pacificmike9501]

This one requires some expertise. When these were originally cast, things were machined in order. The cases were machined for their parting line, bolted together, then the deck surfaces for the cylinders were machined. The surfaces that are required to work together must be correct. A lot of cases look like they don't match., main bearings, deck surfaces, cam bearing to cam cover, they all have to match up. Other than that, cases will vary because they are cast. All those things must be correct. Someone who is a real motor builder can usually correct all of that.
