Looking for machinist help

[Brentc]

I have a Kohler motor on a bercomac snowblower. On the base of the Kohler motor there are 2 small metric m12x1.5 hex bolts that you have to remove to drain the oil. My problem is that there is no clearance to slip a funnel or anything else under the bolt and the oil ends up running down the side of the housing all over the floor. Simple solution would be a standard pipe nipple, but for the life of me I can not find a metric threaded pipe nipple. So I thought I’d ask this group and hope someone who has the right tools could possible fabricate me a short pipe, say 2-3” with a male threaded m12x1.5 end and any size male sae thread that I could cap. Id be more than happy to cover costs associated.

How about using a Fumoto Valve like this... http://www.fumotousa.com/parts.php?partnumber=36
Then just slip on plastic tubing when you need to drain the oil.

How bout cutting a gallon water bottle so it slips up to the drain, the other end is over or in
your drain pan

 

[Brentc]

Saw those.

I dont have have the clearance to thread that on. The existing hex bolt head is about as much room as I have.

Tried that.

That was my first try, no matter how tight I tried to hold the bottle oil just seeped through and down the side. Very frustrating to say the least. :banghead:

Get in touch with Machinegunner (Ron). He can build anything!! :bowdown:

I would think any Canadian hardware store would have the nipple you need. Perhaps you could find it online?

Check these guys out, and I am sure there are many more sources:

Good write up with a pic that really helps.

I think your possible solution will work nice.

While you are waiting, I'd suggest you tip the snowblower to the side so the oil drains out at an angle rather than straight down. The lean might help give you enough clearance.

It looks like you could loosen the bolts that hold the engine down and raise it enough to thread in the adapter, or grind the frame for more clearance.

Contact Kohler they do make drain kits.
We sell their motors

Awaiting reply

I emailed their support folks today.opcorn:

I was thinking you could loosen the bolts holding the engine dawn and slip a piece of shaped aluminum under there to act as a drain funnel?
I've done this two trucks after relocating the oil filter between the engine and wheel well. That way the oil drains to a point after removing the oil filter.

I do like the device you attach a tube for draining.

Thanks, Bob. I just welded a British BREN gun back together. Going to test it today.

How close to the metric thread size is 3/8npt size? If the threads are the same number per inch, a 3/8 pipe tap could be run in just to change the taper. Many metric and SAE threads are the same or within maybe 1/2 thread per inch witch would be of no consequence. The M12.5 bolt and the 3/8nps use the same 27/64 drill size for the tap.

I would look for a M12 hydraulic fitting.

How about this.

Thanks for that info

Ill look into the hydraulic fittings. They show some promise with the small diameter they have. So far most of the adapters are to wide and my situation is a little bit recessed and the adapters won’t clear the space.

Those three links above are exactly what you are looking for! Those guys did a better job than I did Googling for a solution. I didn't find those at all! :banghead:

 

[Brentc]

I ordered fitting this morning

Thanks everyone. I ended up ordering a 12mm x 1.5 male to 1/2 male adapter. Should be here mid week. Thanks for all the links and suggestions.:thumbup:

Now I just hope the snow holds off till then, as my snowblower is sitting without oil in the crankcase.......
