Service bulletin for Milwaukee Eight oil filter

[Durwood]

Added 25% more filter media and retained the 5 micron rating.

  nice to see the MoCo coming out with an improved part.

We did the math on the filter the other day - it's like a 13% increase in volume / media. No where near 25%. And, the port and valve has not changed. how's it gonna provide more flow? Inquiring minds want to know. If you don't take a good look at one next to the standard one closely, you can't see the difference in size.

[Buglet]

  Harley is using the new math.

[FSG]

external dims show a 14% increase in Volume,

what are the dims of the filtering media inside .....  ?,

so until someone cuts one open and measures it remains an unknown

Considering there's a fixed amount of non-filtering area inside the filter, that 14% volume increase may well give them 25% more filter area.

It won't plug up as fast between oil changes. I've found that running an oil pressure gauge post filter that sucker is starting to drop psi in as little a 2500 miles. The K&N never showed a drop even at 5k, but it was 10 micron. Besides, MoCo rarely does anything like that for the hell of it. There is a reason. More media, more safe operational time between oil changes. Side benefit of more media is a bit more flow.

   exactly my thinking. There has to be a reason why...they just aren't telling.

Probably so they can increase the price and delete the old filter. Costs them another 5 cents to build, sell to the dealers for $2 more.

[Buglet]

  It's probably going to be imported as well.

[r0de_runr]

They probably changed their supplier, and their supplier had a few million of these on hand.  Just run them through the printing machine to apply the logo and poof!

Cynical bunch we are.

Recently I had a chat with a rep from a major oil filter manufacturer.   He said HD's twin cam filter was very good and that theirs was as good . He went on to say the HD EVO filter was horrible and their replacement was superior. 

Remember the old really long Evo Dyna filters? 

[Buglet]

   I think the main reason Harley with the short filters on the TC was the crank sensor. The M-8's are not in the way anymore so now they can make the filters longer. I still use the long EVO's filters on the EVO's and some XL's. Harley still has them still made in the USA. Did he say why the EVO's filters were bad. I being using them for the last 29 years no problems yet.

[Jobie]

HD came out with another oil pump in late 2019 for the 2020 models and to retrofit all M8's as needed to combat oil sumping by using an 8 lobe pump for better scavenging.  Are they already having issues with their new pump?  Wouldn't surprise me, it's only Harley's 9th try on a pump to fix the design flaws of the M8's.  Sorry, have little to no faith in Harley any longer.  One would think that after 117 years they could build a VTwin engine [ their bread and butter engine ] without all these issues.  Maybe they should outsource their engines to a small engine manufacturer located in Wisconsin.  They can get it right, at least most of the time and still American made.

I also have been using them for years and never an issue.  He said real cheap internals that are not up to today's standards.      He seemed genuine in his statements and it didn't seem like a salesman spewing buy my product BS

Hi guys, im pretty sure i read some where that the 8 lobe pump also had more volume, that being correct i think they would also need to make sure the filter could keep up with that flow as it got close to the end of it's service life . therefore the need for more filter media surface area. Max

Don't forget the Evo filter is on the return side.

We have a winner!

[PoorUB]

Why would HD build a larger pump on the supply side when they have had sumping issues?

Yep your dead right , i went back to the post that Joe Lyons put up and it seems i miss read it and then let my keyboard to the talking . sorry guy's this is just fake news. the pressure side remains the same but i will stick to my thoughts on the reason to have more filter media

[sandrooney]

Does it really make any difference why they changed it? You gotta buy a filter anyway so why not just buy the longer one?

The can length may have only increased 13 percent, but remember, the filter media does not run the full length of the can.

[yobtaf103]

They made filter capacity larger to make up for the HD tech's that overfill
