DCT filter cover leaking after oil change

[Cruiseman]

I have a friend who, after performing an oil change, has a slow leak of oil coming from his DCT filter canister/cover. I have only changed mine twice, and both times it went smooth, no issues. Have any of you struggled to get the cap back in place correctly?

[Rocky]

I'm betting he pinched his O ring on the cover when installing it?.




Very easy to do seeing you are putting pressure on the cover while pushing the filter/spring back up into the case.
While trying to insert bolts at the same time,while drawing the cover up "Evenly"!!.

The key is to use one hand to insert the assembly with one hand.
Then use the other hand to snug up both 8mm bolts.

The problem is the cover o ring fits loosely.
The solution is to use the "Fork Cap" o ring from the previous gen Goldwing,because it fits more snug into the machined groove in the cover,
so it doesn't get pinched as easily.


2018 o ring spec/part number is.

(39.8X2.2) Honda #

91302-PA9-003

The tighter fitting o ring is.

(37.2X2.4) Honda # 91356-MW0-003


A suggestion would be to have spare o rings on hand if your dealer is far far away??

I used the fork cap o-ring on mine also

If you remove the DCT filter without draining the oil, how much oil will come out?

Have him use a clean capture vessel, Change the o ring-Refill.

(Wash off the area first with Brake clean to get rid of any road dirt?)

[Cruiseman]

Good idea, that was my suggestion to him.

I am curious how much oil will spill out of that area without draining the oil first?

About a 1/4 - 1/2 cup of oil. Without draining the crankcase!.



Seem to me you need to dig out the Camera equipment for a "How to" video.

Seeing this is getting to be a common issue with the ill fitting O Ring.

I am heading over a little later and plan to video tape it. He said the cover is stuck, so I imagine he got the o-ring stuck. May have to grind it off!

[Rocky]

Good ol o ring jambed the cover in there.

This should get interesting.

[Cruiseman]

Do you see anything wrong with this o-ring?

[gray red rider]

That is obviously a "C-ing"

[Rocky]

I always say, if you are going to muck something up. "Do a good job of it"

Did ya bring him a fork cap o ring?

Or did ya just go to rib him a little.

Good Hell, how is that even possible?

No, all I had was a couple of the DCT O-rings. I did not even know about the fork cap hack until today!

I actually watched him install this and he was really struggling. I was on the other side of the bike so I could not see really well. My guess is that he put one bolt in first and got the cap at an angle and when he got the second bolt going, the o-ring just slipped out of the groove. When I did the fix today, I showed him that you have to make sure to go STRAIGHT up with the cap and keep it level.

Honda engineers screwed the pooch on this set up for sure.



The first time I saw the cover and how it had to be installed. (With limited room to work under on the center stand)

I knew crap was going to happen.(And it is playing out)


The smarter way of doing the trans filter change dates back to the GL1000-1200 (Cartridge Filter)


I'd of designed a flat plate with a flat gasket (It couldn't ever get pinched)

With a hole through the center of the plate.

Then use a Bolt, That goes straight up through the plate/filter/spring.

That screws directly into the case.

Like this



It would draw the cover/filter/spring up evenly into the case.

Especially since. It's so easy for some to get it Wrong!! (By tightening one bolt at a time)


This isn't Rocket Science kids.

It's Sloppy Engineering from Honda.

My idea would be to replace the cover bolts with studs. They would be installed into the engine case where the bolts go. Installing the cover would be a smooth even alignment to the engine.The cover could be held with one hand while starting the nuts on the studs. The studs could be retained into the engine case with a stud retainer, something like Loctite. What do you think?

Machined parts need to be drawn together equally.

The issue with studs is.

1. The length needed too get the nuts started. (Don't forget the spring)
2. Some will still get frustrated and tire if holding the cover up against the engine,
and will no doubt tighten one nut more than the other,and be in the same boat.
3. Then again one good speed bump.and one of those studs could get damaged??

It pizzes me of as a customizer to see a company such as Honda do something so stupid. (Don't they realize who there past customers are?-lol)

Yeah, then there is that one guy, threw common sense out the window.

I like your idea..

Thanks for the reply. There isn't much room under there either. Ive been successful 3 times. A nice lift would be good too. At least one could see what the DCT filter cover's doing. That little spring is a menace. Grrrr. Honda could have machined a smaller, tighter, boss in the filter cover for it to sit in.

[Rocky]

Ya know Randy. Looking at these Cover pictures.







I'm seeing an easy solution on a CNC machine. (A redesigned cover)

This OEM cover is just so wrong,and easily fixable.(My wheels are spinning)

[biglefti]

I've changed my oil a few times 30k on the clock and I really don't know why anyone is having issues with that part.

You don't catch on so fast these days.
