Front engine isolators

[mike lowary]

my son has been working on one, 3D printed the housing and looking at different rubbers to fit the job and hold up over time while making it possible to replace at home when needed. He's a machinist...

3D printed housing? As a machinist... I’m interested to see the results.

 

[Cooter]

Same here. I wouldn't trust PLA to do the job, even solid. But 3-D printing metal is here!

IMO, it seems easier to machine that part though.

 

[thrstrmech]

yes, PLA for mock up before he actually machines it. my former company 3D prints metal turbine engine compressor blades, probably other companies doing the same as the tech has evolved.

What grade aluminum will the housing be machined from?

 

[thrstrmech]

6061 or 7075, still sourcing the rubber and making changes to the design as the drawings from the guy who made them I believe left them open...this is what was printed from the original design so far

 

[mike lowary]

Wouldn’t polyurethane be a better material for the bushing? Nice job so far.

If you can find the right material. Is poly. much stiffer than rubber?

There are many different options for poly as far as stiffness. Poly lasts longer. You can buy whatever stiffness you want

 

[mike lowary]

Anyone test the shore durometer of the factory bushing? That’s where I would start.

Ya thats the TPEHAK 'polyurethane rods' deal. He was on to something but never got the durometer right and gave up.
6061 would be plenty strong, but I know a guy with a pile of titanium :eagerness:

With aircraft production dwindling, the Russians are looking for new markets.

Howdy All, I’m only post this hear because I’m not smart enough to navigate this form to start my first introduction post as a new buell member. Anyways I’m post more once I learn or get access to that technology.

Unfortunately, we already loaned out that technology to one of our members. I don’t want to name names, but it was Cooter.
He is a bully and absconded with this technology and we haven’t seen it since. He promised to rebuild it for us on his 3D printer, but so far all he has done is drank a lot of beer. He was in the middle of telling us his story about his trip to Oregon and then NOTHING.

He left us hanging halfway through and refuses to return technology. Until that happens we are at a loss.

What a jerk.

 

[Cooter]

My jerky-jerk face got sidetracked trying to 3-D print a beer. I guess I need a 240V printer for IPA's?

I'm typing as fast as I can for my fickle interneters, I promise!

Thats "Jerky Mc Jerkface"

I see that the initial front isolator was replaced by L0501.02A8, then again by L0501.4A8. is this correct, and is there more?

How many updates is there to the front isolator?
Which number is the newest one and most updated?

 

[34nineteen]

This part is most likely discontinued from Harley and no more are being produced.

I think Twin motorcycles is offering a reproduction part.

I contacted them. They told me the part is still under development and not for sale yet.

Has anyone tried this?

[34nineteen]

The isolator just became discontinued recently, so any alternatives have probably seen few purchasers, and the aftermarket ones only have a few months on them.

 

[Cooter]

I honestly can't count how many Buells I've had, some over 50k miles, and none have never a bad one or had to replace one.

Are we panicking? *Nervously walks out to the garage for a peek.
