Oil change - filter differences.

[pekingduck]

Honda's reputation for reliability was built in large part on those centrifugal oil filters. From the first step-through 50s, through the DOHC 450s, and still today as Tev62 says. I remember servicing tons of them, pulling off the filter or clutch covers, scraping out packed-in metallic sludge, sometimes 1/2" thick. They are remarkably effective but become less so as they fill up.

I don't know why you guys don't just use K&N filters. The KN204 has a convenient nut welded right on the end that you can use to really make sure it's tight when you install it. Been using them for years.

I've been under the impression that fine oil filtration is not necessary if the engine has non-plain bearing crankshaft journals (?). With ball or roller bearings handling the heavy loads there is not the dependence on having a fine high pressure layer of oil between surfaces to discourage metal-on-metal contact as with plain bearings. True ?
My old CB350 was like that and my XS650 is like that. The XS650 OHC runs on ball bearings, I can't remember what kind of cam bearings are on the CB350.

Hey Gone, I like that nut on the K&N. I use a socket with a big breaker bar and torque the snot out of it. No leaks yet

The centrifugal oil filters are used only on Hondas with ball and roller bearing bearing cranks, up to the '76 CB500T. They never used them on plain-bearing cranks. Like all plain-bearing cranks, old British bikes had sludge traps in their crankshafts. Without an actual paper filter, their cranks needed to be taken out, the grub screws un-pinned and removed, cleaned out and re-staked as part of their long term maintenance schedule.

I've never used anything but OEM filters on any of my bikes except for the dirt bikes where I'd change them every 10 hours so it doesn't really matter that much, but I'll admit I got a HIFLO for the last oil change on the CB because the dealer didn't have one in stock, was expecting delivery time of 45 days and I just wouldn't wait. Filter itself seemed solid, yes just like the guy in the video above the seal was pre-greased, went in no fuss, bike seems to be running just fine, I don't really know what to look for that would be different

Oh, I thought K$N's 17mm nut on the filter was a security measure so no one could steal the filter. You tighten the nut until the the spot welds give way and the 17mm nut is gone.

Now let's see someone steal that filter!
