440 in action on Mother's Day

Post by whiteclipse16 » Mon May 11, 2015 6:27 am

Since the weather was pretty much perfect yesterday I decided it'd be wrong to not get the dozer out. I was even able to talk the wife into doing the operating.
This is the only pic. I got but we pushed up some wood into a pile and "groomed" a dirtbike jump for my brother.
Old girl fired right up and ran great. My "slobber" is gone from what I can tell however I'm still getting a fair amount leaking out of the breather, I'm wondering if that means blower seals are bad.

IF you mean blowby out the crankcase breather, I can't see that it would be the blower. Normally, I think if the blower seals go out, the engine runs away.

I'm not sure if that's what they consider the crankcase breather but the "Air box drain tube" is where the oil comes out. I don't have the removable cover like they describe in the book.
It comes out probably 1 drip per second.

Okay, that is for the most part normal, keeps buildup out of that area.

That is good to hear. There is a pretty decent write-up in the manual on checking the air box pressure, exhaust back pressure, etc. so I might take an afternoon and check those things to see if they're in spec.
I'm not quite sure how to check the air box pressure without getting oil into the gauge that I use to check the pressure, however it might not hurt the gauge I'm not sure.

Hi,

The common gauge has a curved copper or brass tube inside with the far end closed and not supported. The pressure causes the tube to try and straighten out, causing the far end to pull on a link, working a sector gear, which turns a gear which moves the pointer.

So, a little oil will hurt nothing. Unless....You next use that gauge on an oxygen tank. In which case the gauge will explode like a small hand grenade....

Gotta keep the oil away from O2 under pressure.... ;)

Edit: Note, this would be pure oxygen, like for a Hot Wrench. Not compressed air. Only 20% O2 in air....

Wow, thanks for the lesson on gauges Stan. I had no idea that all that went on to move a gauge. I guess it probably isn't too complicated, just not what I was expecting.

Pop pop, I agree, it does seem excessive, but considering I only run it a few times a year, it's not too big of a deal. I'd still like to check the air box pressure just for piece of mind.
