Title: Specs on opposed rods
Post by: 86turbodsl on May 24, 2019, 07:44:01 PM
Does anyone have specs on the pressure lube holes / rod dimensions?  I need to figure out what the 42" pressure lube rods have for oiling provisions.

Thanks in advance.

Are you talking about stock rods, or ARC rods?

Stock rods.  I'm not racing, i'm just trying to assemble a pressure lube motor that somebody before me completely screwed up with non-pressure lube rods.

If you are just assembling a stock motor, then buy the new rods and install them.

i can't find the proper rod part number.  I am going from a 40cu engine to a 42 cu engine.  The original pressure lubed 12.5hp engine was underpowered.

And don't tell me to just go to a small engine repair shop.  They are all useless around here.

Don’t waste your money on that crappy engine.    Go buy a bigger v twin if you want more power. 

You can buy a Chinese knock off of a Kohler v twin for less than the Stock rods will cost.  And it will bolt right up.

I would, but i'm kinda stuck with it.  The engine is directly under the operator.  It's one of the old zero turn mowers like a Grazer/Ingersoll/White/Deitz.  I've got a MAX engine height of around 19-20" and all the Vtwin horizontals are taller than that.  I ALSO have to have pto on both sides to drive the deck and the hydro motors.

About the only thing i've found that MIGHT work in it's place is a Kubota Z482 diesel.

Do you have a link to where they're available? Thanks
