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 The previous version was outdated and no longer supported.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

Why am I leaking oil here?

Husqvarna
AA Class
Bike is a 13 TXC 310. Motor went thru a big heat cycle. Now I'm leaking oil from hole in front underneath waterpump. Bike runs great and was supposed to race it tomorrow. Looks like I'll have to.use my backup bike. What is causing this leak?
I just replaced oring on gear shift selector, Oring melted. Got that fixed and noticed this oil leak. Damn....I might just have to send whole motor to Zipty to what else happened to motor. Not happy. All caused by Shitty rad hose routing by Husky. Motor has maybe 14 hours on it after last race debacle.

PS...backup bike is a sweet 03 Honda CR 250 converterted to a Hare Scramble bike. Bike is so lite and handles so sweet. I need to race this bike more often!!

Nope oil is fine. No water in it. Coolant is fine also. I ran 2 heat cycles with straight water to flush system and there was zero oil in it. That's why I'm confused.
 
There is very little leaking there... Did that leak just start? (A new bike should not have a water pump seal go out)

Seems like there is also a large rubber piece that seals around the spark plug ... I left mine out once and I think oil poured out that hole ..Still, oil was in the water ...So this is a little baffling ...
 
Plug is returned back to the way it came. Oil leaks out of hole you see once motor is running. Pretty good flow. How's that TC 250 I sold ya running? Miss that bike. Felt a lot lighter that my 310. Kinda wish I still had it. That rekluse is pretty sweet!

That bike is doing nothing but kicking a$$ :) (~140 hrs now) .. and I finally committed myself to learning how to ride with that rekluse ... That device makes bike riding too easy so I can tell now why so many are hooked on it :)

That leak is pointing right at that WP seal ... You just have to remove that pump cover if someone can not give another explanation :( ..
 
If the husky water pump is anything like the rfs ktm, there's a no mans land between the oil seal on the head aide and the coolant seal on the water pump side of the impeller shaft. If coolant leaks out, you blew the water pump side seal, if oil its the oil seal on the engine side. Since you cooked that motor, I'd assume the oil seal probably melted like the other seals you had to replace. Not a big deal to change those seals I believe.
 
pull the valve cover off and remove the spark plug aluminum tube. There is an o-ring under there that will leak like that if its torn or worse, missing :eek:
 
Just stick a screw with high temp RTV in the hole, kick tire, light fire.
Actually I'd be suspect of any and all seals after the toasting it took. Good call on not making it go racing unless you've got a spare motor lying around like a big race team.

If it's not a play bike, then treat it like a racer and go through it top to bottom. If it were me and I had the funds that motor would be sitting on Ty's bench right now.
 
I wanted to make race next weekend before I tear motor out and send it in. Hopefully Tinken will chime in here and let me know for sure what's causing oil leak so I can order parts.
My backup bike is being ridden by my bro next week. He's going thru a divorce and is getting back into riding after 6 years. Wife did not want him riding. Well she's gone now.....so it's time to ride!

Haha, the ex wife part is kinda funny. Where's your race next weekend? If it is anywhere near me you are welcome to race my xcw-300. You can swing by and pick it up.

CORCS in the springs. You can rent one from Big D Motorsports for the race if you can't sort that out. They have a black and red head txc310

Thanks for the offer. I don't like racing bikes I've never ridden. If I don't get bike fixed by this weekend I'll just go support my bro. He needs the ride more than I do.
 
Anyone every rebuilt the water pump on this bike. Looks simple according to manual. I don't undr how your supposed to get seal out. Need to get this out to get to snap ring. I'm hoping this will fix leak. I'm flying blind here!!

Wish I could help there but I've only changed that WP seal on my TXC bike that is a different engine ... The only real issue on the older engine was the timing chain was hooked right on a gear on the same shaft as the water pump gear. That meant the bike could get out of time it the timing chain was removed .. I'm not sure the design is the same on the xlite engines ..

With that said, ...I would verify that seal around the plug is not allowing just a little leaking before I tore into the pump seal ...

Just pull the plug and that large rubber gourmet and verify no dirt or whatever is allowing a small leak ... this can be checked after you have removed the valve cover ...

Good luck and I'm sure you will get some details on this job ...
