  • 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 The previous version was outdated and no longer supported.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!

010 TC250 blowing oil from behind water pump housing ...

Can someone shed some light here?

After adding oil back into my bike to fill the sight glass to the half way point, I started the bike and rode it a short distance and now it is blowing oil out from behind the water pump housing ...

My first thoughts are the pressure releasing hose out the top of the engine is clogged ...Nope, it checked out to be open ...

Next, did I overfill the engine oil? Several CCs of oil did disappear from engine I guess as no oil was in the sight gauge with the bike standing straight up ... I added enough oil to fill the sight gauge back up to the middle of the gauge ...


Anyone got any clues?

The small gear at the bottom of this pic is what the water pump seal and propeller are riding on ...

1) How do I remove that plate from against the engine head? I'd like to NOT ruin the water pump seal if possible ...

2) Does anyone know what exactly is behind that plate that the shaft and waterpump seal are part of? Is there an O-ring back there or a gasket? I'm guessing the leak is there and I need to repair it ...

I found a parts manual thanks to the google search engine ... Looks like a large gasket on the back side of the plate ...

Still looking for info on how to remove that plate #12...

Part #14 is a Split ring ... That's a little interesting ...

I've got a friend here from the UK who is helping me ...Hex ..the same guy would twisted his knee and ankle a few weeks ago riding with me in the mountains ... He's making me a gasket now as I type ...

Anyway, the plate can just be driven back off from the engine without doing any other work ...Just maybe rotate the engine until you can feel some play in the small gear and then just tap the plate out from the engine ... The entire plate, seal, and gear will slide out of the engine ...

Next the shaft holding the bearing and gear can be tapped out of the housing ...Lots easier than the older engines as the timing gear itself was an issue with them ..

I'm still not sure what happened with the leak ...

At first oil change ... I added 1L of oil after changing the oil filter ... Is this too much oil?
 
Little interesting here ...I can't start this lovely bike to verify the leak is fixed because it will not start BUT the leak is back just from the 50 kicks or so I have done trying to start it ... :0 ) ... I'm starting to understand why these bikes are not at the races ...
 
800 ml's is all it takes. I've found that if I fill to 800 ml it barely shows at first in the window. If I lean the bike over a little it will flow into the window and when upright will settle a bit.
Heat it up and you can see for sure what the level is. (but I guess that's a bit of a bitch if you can't get the thing started).
I've overfilled before and it just blew the oil into the airbox...

Thanks on the oil amount ....

Here is the leaking problem ... I miss-diagnosed the issue ....

Look at the red circle in the pic .... There is a hole there that goes into the engine ... I don't see any part listed that goes there to fill it ..

Can someone please look at their head and see what fills this hole on their bike? It is behind all the waterpump stuff and up in the corner of the head almot hidden ...

This has been a wild goose chase ...or else this is the devils bike I now have ;0 )

Apparently, way back when this oil leak appeared, it was due to me inserting the plug socket and apparently getting the white rubber washer out of alinement... Next I removed the gasket ... just the wrong thing to do as this gasket seals the engine oil from the plug ...

The hole in question in the pic above goes all the through to the plug ...apparently as a drain ....

Case closed ... Now, back to starting this beast ... :0 )
 
Sorry i just saw this. Could have saved you a ton of trouble because the same thing happened to me. Of course people told me that couldn't possibly be the reason but now i have proof!

Anyway glad you got out fixed and sorry again.

No problem and I haven't cranked it yet but I'm sure that is it ... That plug hole is centered inside and below the oil line splashing in that engine ... And I stuck a zipty through that small hole and it went into the plug well ...

It only cost 1 baffling day for me and I found out how easy the pump seals are to change ... I've got a few days to spare currently ...I'm feeling alot better about the bike and think the worst is behind me
 
would anyone happen to know how many ml of oil a 2008 txc 250 takes? and how often to change it?

My manual says 1.8 US Quarts with filter replacement ... I always used the sight gauge on mine ...I just added oil till the sight gauge was 1/2 full with the bike standing straight up ...

Also, there is about ~1/4 cup of extra oil that can be drained from the front small oil screen hole AFTER the plug has been pulled and drained ..

Oil changes are very subjected on time and oil ... I used true synthetic oil in my bike and tried to get the oil changed at 300 miles or so ...
