Cub 154 engine to F-Cub
Will an engine from a 154 loboy fit in an F-Cub? I know nothing about loboy 154's and have the chance to buy one for a pretty good price and am just wondering if the engine will fit. What are the advantages other than 4-5 more HP and more RPM?

Re: Cub 154 engine to F-Cub
I know the block casting is different to fit the larger 12v starter. And also, the crank doesn't have a pilot bushing, but I suspect you'd be able to take care of that.

It is my understanding the some of the early 154s did have the pilot hole drilled in the crank.
When you only have 9 horsepower you need to know the names of all of the ponies!

Re: Cub 154 engine to F-Cub
I believe the block casting is the same as other cubs for that year, starter will bolt in place, crank pulley is different as well as the charging system. Some guys have said the crank may not be drilled for the pilot bushing but that's fixable. Governor has different weights, original head is R2, aluminum domed pistons, early 154's had IH carb and might not have the larger ported manifold for the Zenith carb. Might be some other changes that I can't think of. As for transplanting a 154 engine into a FCub, it's been done. Rockfarmer did it a few years ago, I have the remaining parts for spares for mine.

Re: Cub 154 engine to F-Cub
Shane, the engine I transplanted was from a '71 154. The pilot bushing hole was already in the block so it was easy to rebuild. Machine shop overbored 0.03" and installed new pop up pistons and a did a valve job. I run the zenith with 1.5" pipe. No problems so far. I think the block might have been 1/4 " longer than a standard cub...I'm sure someone will chime in on that soon.. I did not measure but remember the ears being thicker where they mount to the front bolster. That and the dash seems to be slanted a little more forward than my other cubs.
FYI...It sounds better at 2200 rpm than at 900 rpm.

Re: Cub 154 engine to F-Cub
Thank you everyone for the info. Here’s the tractor. It may take a year to get it, the owner is restoring another one and wants to keep this one until he’s done. He sent me these photos. I don’t need it but the price is right.

That's a decent looking 154. Even the grill doesn't look busted up.

It does look good from the pictures, I haven't seen it in person. I've known the guy 25 years and didn't even know he had this tractor.

Just from the pictures, it looks good enough I wouldn't part it out.
