In our quest to build a big horsepower Milwaukee Eight powered Softail we decided to start with a S&S Cycle flywheel assembly that would help us ultimately attain a whopping 131 cubic inches of total engine displacement. It may seem like a daunting task tearing into the bottom end of your motor but we walk you through the steps to make sure you are on your way to building a big horsepower monster.

If you are looking for more info on how to get to this point in the build you can see our full M8 disassembly video here • How to Disassemble a M...
For the install you will need these:

And you’ll need a press to get it all back together!

It's not just someone building a hotrod, they are probably doing a big build due to the fact the crankshaft run-out is past HD specifications.... Thats usually why people do a full build...🤔.. Living The F 🤪 KING Dream Safe travels 🙏♥️🐾🐾🇦🇺

Doesn’t belt need to be around transmission sprocket before installing swing arm pivot bolt?

Which bearing did you use? If I remove the balancer on a bagger, would I need to get the bearings out of the case?

How do you sych your balancers on a touring M8?

How much will it cost to get that done on a 2008 Electra Glide Ultra Classic?

Great video! Will take my crankcase out this weekend. My question regarding the S&S flywheel. Did you check the run out after you installed it and how good was it? Do you know how true they are? I have a Feuling race oil pump and the tolerances are really tight. Still thinking about to get mine trued and welded.

yes, I did check the runout it was less than a half of a thousandth. Which is what S&S claims on their flywheel assemblies

Two questions... why not do a Timpkin bearing conversion, and is it ok to leave the counter balancers out? I assume not, but i thought i'd ask.

@jpcycles Жыл бұрын

If it was a Twin Cam I would have done the Timken conversion. In my opinion the Timken conversion on M8's is still up for debate. Have talked with different builders and there doesn't seem to be a solid consensus for it either way. Time will tell I guess. As far as the counterbalancer's, yes you can leave them out but you need a spacer in each spot where the balancer used to be and make sure your crank is set up for no balancers . - Patrick

@jpcycles hi Patrick, to confirm, it looks like you used a upgraded koyo bearing rather than the HD bearing? Would you be able to confirm the koyo part number please?

@RickyG512 7 ай бұрын

Hi Patric, do you know the power rating of your hydraulic press? The part number of the grey Jims tool to guide the flywheel in?

@jpcycles 6 ай бұрын

The press is a 20 ton from Harbor freight. I cant seem to find the P/N for the grey tool. Honestly you could use a piece of PVC or just be really careful. - Patrick
