repowering exercise - B&S Intek 206cc on 10000 series

So a while back, I snagged this Ariens 10000 series and decided to do the ubiquitous Predator 212cc swap on it, only to realize that I couldn't get the clutch working quite right and sometimes the snowblower would creep forward even when in neutral. To make matters worse, 2 of the grease fittings on the augers came off and would not thread back on. I lost interest and the Predator engine was moved to a different project. So this shell sat for a while, untouched and unloved.

I then went through a phase where I started buying pressure washers that need work. One such purchase was a pressure washer that had a leaking pump. It was $20 and it came with the wand and a running engine. I was able to remove the pressure washer pump from the block and voila... here was a modern OHV horizontal axis 6.5hp single shaft engine with a 3/4" shaft, and an engineless snowblower sitting nearby. I became curious.

Wouldn't you know it... it is a drop-in replacement for the Predator as it also shares the same engine mount bolt holes as the old Tecumseh 7hp engine that used to be in place. I'm using the 924000 series chute crank pieces to clear the block. The only thing I haven't come up with with is the belt cover as there isn't a suitable threaded hole on the block for the belt cover bolt.

I did get the clutch issue sorted out and the grease fittings are back on, but I may use the engine on a different snowblower where the belt cover is bolted down on the frame itself and not on the engine block. Anyways, if you guys see these Intek engines on CL, give these a chance.

On with the pictures:






There's a youtube video that suggests that similar Inteks made in 2001 and earlier are made in the USA. I haven't had a chance to verify this, but this engine in particular has a 09/17/1998 date code stamped on the valve cover.

The part number on the engine is 121432-0021-E1, and is called the 120000 Model Series in Briggs literature.

You might look at some of the Toro snowblower belt covers. They look pretty darn close to the correct width and bolt down at the edges.

There's just one thing I'll guarantee , the best things in life, they sure AIN'T FREE !!

Nice fit!

The jetting may be on the lean side for winter use. Are jets from their snow-engines interchangeable?

Thanks for the suggestion, I looked up the main jet for 121432-0021-E1, and there are several:

117 690048 Jet-Main -(Standard) -Used Before Code Date 10040100
117D 798652 Jet-Main -(Standard) -Used After Code Date 10033100 -Used Before Code Date 12010100
117D 591298 Jet-Main -(Standard) -Used After Code Date 11123000

I looked up the main jet for a 120000 series snowblower engine, 12D413-0017-E1, which is a 7.5hp engine, its main jet is also 690048. I think I will be ok.

I built a few custom machines for a landscaper with similar 10 HP engine, I ended up using belt covers from some craftsman/mtd/Murray older machine. Here are the pix, zoom in to see if it will be what you need.
Hard to remember exactly what I did as it was a few years ago, but I believe I had to notch out where the clutch auger levers go, also I made an angle bracket on the top Where It Bolts to the block, and also I had to cut a horizontal slot where the Chute teeth ring gear went, and bent up a bracket to bolt guard to the tractor chasis. If on your engine the holes around the crankshaft are not threaded, you can just tap them. Hope the pix help you.

P.S.
If you make belt covers with this setup, you now have a spot to put extra shear pins !!

Nice pics, Shaw351!

I flipped a Craftsman 9hp snowblower a while back that had a similar belt cover with the shear pin storage unit up top. I'm sure I could find a suitable belt cover, but I also happen to have an Ariens 10ML snowblower that currently has a Predator 212cc where the belt cover gets clipped onto the frame. I was thinking about putting a Predator back on this blower, and then install the Intek on the 10ML

Just bend some light sheet metal or flashing and pop rivot to old cover ... that way you can use existing cover and bolt holes on block, etc.... I did that to one of mine, works great.

One of mine engine swaps the end of the shaft rubbed the cover ... no problem, just drilled a hole in the cover , easy peasy ..

I found a slightly damaged Ariens 924000 series belt cover from my parts bin that I didn't mind cutting up, trimmed it to clear the clutch and auger levers, found a flange bolt that threads into the existing hole in the block, and then cut a slot on the belt cover so that the flange portion of the bolt locks the belt cover in place.

Now... only we got some snow around here instead of this freezing rain business today... On with the pics!





Finished it off by adding a piece of heater hose over that bolt so that it keeps additional pressure on the cover, and also prevents the bolt from going deeper into the block than it should:
