Title: Bigger engine, chassis mods
Post by: BuiltTough on April 21, 2018, 03:26:12 am

Good day folks. I’m working off a mastercraft/mtd frame. Stock engine was a single cylinder 12hp B&S, I’m putting in a brand new 24Hp vtwin.

Looking for ideas as to how to make the new engine fit. Has anyone done similar? I was thinking about stretching the frame a few inches but not sure if this is the best option. Any input would be happily welcomed.

24hp Briggs vtwin should bolt right in.
the Masterkraft chassis I've seen are the same as the mtd chassis I've used before

That would be pretty sweet if it did.

Is there any benefit to extending the frame? Looks like it would be pretty easy to do I. This frame.

Most engines have a universal bolt pattern and so do chassis!

I still have to have a close look, but it would appear that none of the bolt holes match up with the new engine.

Let the customization begin.

No,the longer the wheelbase,the harder it is to turn!!!

I stand corrected after some careful positioning, the new motor does match a set of holes.

One less thing to do! Getting excited to start this build.
