Hi all , I don't know if the subject has been asked before ...if so I apologise ...my landlord 3410 has a 10hp cast iron engine which I really like but parts are hard to come by....but in the UK the horizontal aluminium engines are quite plentifully...so my question is are they directly interchangeable ..are the mounting holes the same dimensions , is the shaft the same height e.c.t

has anyone had any experience of changing out these engines

I fully intend not to swap out my cast iron engine ...but if they are fully interchangeable it would be foolish of me to acquire an aluminium engine if one became available at the right cost

I don't think the bolt pattern is the same, and pretty sure height of the crank shaft is also different.

cheers Rokon .

that's my concern, if that's the case then I will need to nurse my cast iron unit for the next 30 years, ive just ordered a new set of rings from the US ...tell me ...my bore is in good condition , no scratches or lips at the top, but I am getting a little oil getting past the rings into the combustion chamber ....the rings I have ordered are chrome ...did I read it correctly when chrome ones are a bit better for older engines

Hi snorky. I too have a 3410 with the original motor. I can't help with your question but I just wanted to say how good my 3410 is and has been. I bought it used about 9 years ago and use it to plow snow, mow grass, and general towing of a garden cart. I have never touched the motor except when I bought it. I removed the head to clean up the carbon buildup and new gasket. That is it. Always starts easy even in cold cold winter mornings. I have listed it for sale a couple times with no takers, so it looks like I will keep her for the time being. I only want to sell is in order to get another project. (I currently own four Simplicities). I see no reason for yours to not last another 30 years. Keep fresh motor oil in it and operate with a light touch. Good luck!

I put an aluminum Briggs 11HP in my 3410 several years ago. Model 254427 I had to use spacers to lift the engine about 1.5". I also used the original S/G pulley to mount the driveshaft, but I use the ring gear starter, and the engine's charging system. I still need to change the original starter switch, to one that grounds out, but for now I have a pushbutton to shut it off.

It's do able, and IIRC, not real difficult.

One other factor which may or may not be an issue is the wieght of said swap. A cast iron engine plus s/g will wiegh a lot more on the front of the tractor than an aluminum one. If you do hills and pulling stuff that could make it a bit more prone to lifting the front unless you counter it with something.

+3 on the 10hp oem engine though. I just did a rings and rod job(reccomended) on my dad's 2210 with the same engine. If you do the rings, I always reccomend the rod because it is aluminum and it can crack and do nasty things. It might not, but I have had rods fatigue as well as pistons at the ring grooves. Inspect all the aluminum parts carefully, because if you do you will likely get another 20+ yrs out of it well cared for

[dentwizz 6]

Should. That looks like the newer version of what I am working on to go in my HB112.
