  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Difference in oil filters

I have an 08 TE510 and have been using HF154 oil filters in it. I think I am on my 8th or 9th filter now. What is the difference between the HF154 and the HF563? Am I using the wrong filter?

Are you guys using the HF154's in your 08 TE's?

Why are the HF563's almost twice the price as the HF154?

If I remember correctly, the HF154 looks just like the factory filter that came out from the first oil change.

Mid 08 factory revised filter just a bit, it's a little larger, fewer pleats and heavier bypass spring rating.

I've got two HF154 and two HF563 (loaned 2 154s to a buddy breaking in his 310 and he returned 2 563s, nice on ya Tannan.)

I plan to use the 154 first, as that's what I've run for 3000 miles, but 563 are now available and should be used going forward.


A search of 'HF563' turned up this:

Thanks, Brett. I will use up my supply of 154's and then I will probably go to the 563.

After reading the linked posts, it sounds like the 154's were fine to use until they came out with the 563's, (like a year later) now we should only be using the 563's.

My minuscule brain is having a hard time wrapping its self around this concept. It seems only logical, if the 154's were fine to use in the many months before the 563's were available, they should still be fine to use.


Is there an actual risk of engine failure from using the 154's? My bike is an early 08 does that make a difference?
 
Hard to believe there is much risk or we'd hear about blown up 08 engines. But, I bet the lubrication engineer either changed his mind or actually got around to analyzing the pressures and flow measurements with the higher flow 08 oil pump and made changes to the filter. :)

563 is yellow, 154 is red

My 09 came with the new ones- but they weren't available right away- so I had ordered 5 154s from George- The 154s upon comparison seemed a cheaper version do mainly to the sealing surface- but the apparent main issue is the bypass...thing on the opposing side.
When George said he got these in and described the improvements I bought 5 of the 563s- I guess I will use the 154s if I run out of the 563s in a pinch or give them to my buddy with a 2005 te450-
 
Has anyone seen the actual psi difference listed some where for the bypass? I really wonder how much diffrent it is.
 
I was just looking at a filter, and the bypass pushes in from the outside of the filter. So if the oil goes through the filter from the outside of the filter to the inside, why have I been cutting my filters open and looking for particles inside the filter?

If the oil does goes from the inside to the outside what purpose does the bypass serve, the more pressure inside the filter the tighter the bypass would seal. then it would be up to the spring between the cover and the filter to compress, letting the oil bypass.

When looking at a filter, the supporting mesh is inside to keep the paper filter material from crushing, so the oil must flow from the outside in. I guess I can quit cutting those filters open now.

Am I missing something here?

My finger spring dyno tells me the spring on the new 563 is 'slightly' stiffer, maybe 10%.
 
:cool: So what? Now we are to use the 563 in the 08?


For sale 10-HF154 4.50 each. :lol:

I'll use them up and then switch if that's the case. :D

I never understood the cutting open myself- it flows from outside to in.
But you can better see what is inside each flap (inside the outside:busted:) if you cut it open- I suppose.

You are correct, oil flows from the outside to the inside of the filter, you should never find anything inside...

From the workshop manual, lube flow diagram, filter is on the right...arrows call out the direction. White arrows are primary, black arrows are secondary.
