Missing parts on oil change

Hi newbie to the forum hope I’m not in wrong location to ask this , 2012 silverwing first oil change since I recently purchased it, pulled out drain plug no spring or filter screen to be found. I’m in Arizona in the states any links to purchase this or am I ok without it.

I’m new(er) to the site, so I’m not sure to be honest- that said, I have serious doubts about the utility of the screen and spring. I suspect as long as you change the oil regularly (and avoid sludge buildup/ use a good synthetic), you should be fine.

I would assume (maybe wrongly) the screen traps small particulates of metal that fall into the low oil pan (but isn’t that the job of the oil filter as well as the oil pick up tube screen?).

Actually, there is a thread about it:

If it bothers you and you want to replace it, I’m sure Partzilla.com or Babbittsonline.com have the parts. I really have no idea what it’s for- I have 2 Honda MC’s (ST1100) and no such spring is on there.

I bought my SW with a fresh oil change- when I change it again, if I don’t see it, the scoot runs just fine…I likely won’t bother getting one.

I never really figured out the purpose of this screen because of the way it fits, but I feel better knowing it's there. The first time I came across it I discovered that it had been inserted upside down. It fits either way!

If Mr Honda thinks it should be there then I would fit one.

OK, it’s been a slow day and I’m off today so I did a little bit of research into the problem as well as consulting with my brother in Colorado. Attached is a picture of the lubrication diagram from the shop manual. It is quite interesting in that it appears that that strainer is the only strainer in the system versus a mesh strainer on the oil pick up tube (as would be expected). So it appears to be a necessary component of the oiling system.

So now when I do my oil change, if it is missing, I will have to get one.



It is probably one of those parts that a mechanic would just assume doesn’t need to be there and leave it out due to laziness.

Bravo! Now it makes sense. Good work

Seen a lot of scooters with missing oil screens, some left out by careless mechanics, some removed by owners for better oil flow   , on some scooters/motorcycles is the only means of filtration.
But is really kind of odd that is serviceable on a scooter engine that has a replaceable oil filter, IMO is more a metal contamination/failure detector on an engine with virtually no failure history, is "Like a Screen Door on a Submarine" = useless   , on most vehicles the oil pickup screen is not user serviceable, no need  

IAC, with all that said, I would still install one at under $10 USD for spring and screen, https://www.ronayers.com/oemparts/a/hon/506c792df870023420a3c0b4/crankcase

I'd install that screen it stops any large particles from going through the oil pump. It has tight tolerances and will wear or damage it. A well-maintained engine will have almost no build up inside, but others will have hard oil deposits that can flake off and get pulled through.

Every Honda engine I pulled the oil pan on had a screen on the pickup tube.

Any metal in there it's already too late damage is done.

If Honda think it's necessary I would go along with their decision on the matter, their designers know more about these things than I ever will.
The replacement are ridiculously cheap.

" their designers know more about these things than I ever will. "

Maybe so in most cases, but plenty instances of "Design Flaws" out there, that caused plenty headaches and/or user had to fix !!, recalls and failures on any type/brand of vehicles in general, seem more common now-days, poor design or engineering Fortunately, the SW600 is not one of them.

I too have wondered at this filter screen and spring but since my Wing was bought new it is still installed. My Forza does not use this system and both scooters use a spin on filter...

My grandson had a Kymco Like 200 and it used the spring/ screen system but had NO spin on filter.

Thanks for all the feedback I am going to get the parts needed.
