9020 engine transplant, but not what you think

Recommended Posts

So...I found I actually rather like the Onan powerplant in my 9020. Even though it has an unknown past and rattles a bit (need to adjust the valves), it's smooth and has a pleasant sound. Yes...I know it costs more than a Mercedes Benz to rebuild...

So I was googling around at what other Onan engines were available. I have found there was a 24HP variant made. Do any of you know if it has similar dimensions to the CCKB? It'd make a neat drop-in and would keep the lineage intact.

Here's some drawings with dimensions of popular engines--if the dimensions are metric, just divide by 25.4 to convert to inches:

KOHLER COMMAND:

KOHLER MAGNUM TWINS:

The Kohler Magnums will have the same basic dimensions as your KT19 (M20) and KT17 (M18).

The drawing is fuzzy, but I figured the Height, Length to end of Crank, Length to Back of Housing, and Width.  I've inserted the figures and put a red box around them.

BRIGGS & STRATTON I/C FLAT TWINS (13, 16, 18 HP):

B&S VANGUARD 16 HP:

B&S VANGUARD 18HP (may be same dimensions):

Onan P220 (B43 & B48 Similar):

It looks like the V-twins aren't any taller than the flat twins in most cases.

 

I hope this is useful...
