Mini Jeep engine help

[bparker]

I am a first time poster and looking forward to learning from the group. My son, Bryson is 10 years old and has a mini Jeep. Unfortunately, the motor has stopped working and has no compression after only 1 year of use.

I have taken the motor out of the Jeep and I am curious as to any recommendations you might have for a “more reliable” motor?
I know welding and lots of work would be required, but I would love to learn from someone who has more knowledge than I do.

thanks in advance

How many teeth on the axle sprocket?

 

[Denny]

I just bought 2 of those myself. Have you thought about rebuilding the original or buying a new one?

A more reliable engine would be a predator 212, Honda, or Ducar 212. Just know that adding an industrial style engine like a 212 will be lots of work.

Did? Better start a thread on right now Denny. That is of course, if you know how to operate a camera

Someone should build an electric version of this to put in a parade. oh wait...

 

[Denny]

Actually they do make an electric version. Big money though!!!

Axle Sprocket has 38 teeth
Motor Sprocket has 12 teeth

A 212 ain’t going to cut it in this particular situation. It will need at least a 420 & electric start and a fnr transmission. In my opinion the Honda engine that it is based on is one durable piece. What kills them is idling for long periods of time or driving at slow speeds. Because there is no fan they overheat and kill the cylinder walls and piston. They make an aftermarket oil cooler and lines for these engines that are quite easy to install and help to keep the engine cooler. Also the addition of an under hood fan blowing at the cooling fins on the cylinder and head is a big help too. There’s just not enough air movement under those things to keep the engine cool. Is the engine on yours front or rear mounted?

Yea, but it also has a 3 speed manual transmission. Or is yours the automatic?

Rear mounted.

The original motor is a 154FMi Chinese made motor. If I replace it with the same motor then I will definitely look into an oil cooler kit. That would be helpful for sure.

I would also consider a running a high quality synthetic oil like Amsoil or Royal Purple.

 

[panchothedog]

A strong electric fan sounds like it would be worth the hassle. Good idea.

 

[Big Bob]

Although it would be a lot of fabrication, you could go with a gas golf cart transaxle and torque converter drive. Hook a bigger engine to it. The golf cart transaxles are pretty reliable and have Forward/Neutral/Reverse.

 

[Denny]

There’s not enough room for all that under it. These things run over 40 mph. And even used parts the cost would be prohibitive!

Got ya. How about these?

 

[Big Bob]

The one on the left looks like yours. May even bolt in.

 

[Denny]

The one on the left is what I’m suggesting. Except he needs to find one with reverse also. The 250 is way too tall to fit. Those engines are pretty easy to work on if it just needs a jug and piston or valve and head work.
