Komatsu FG14:
Replacement engine advice needed

Hello everyone.

I have a problem with the engine in my little Komatsu forklift, and I was hoping someone could help. The machine is an FG10-12 which I'm led to believe is an import model here in Australia, and it's powered by a Toyota 4P petrol engine & a single speed automatic transmission (forward & reverse).

The problem is the engine. It's near death and needs to be rebuilt, but the 4P is a virtually unheard of engine in this part of the world and I have trouble buying even the most basic tune up parts for the thing let alone anything heavy duty.

What I would like to do is replace the engine with something that is more common down here, and I understand that this particular model was also available with a Nissan H20 engine.

What I was hoping is that there may be someone here who has some experience with either or both of these engines and would know if such a swap would be feasable without re-designing the entire machine, as H20 engines are reasonably well supported down here and changing to one would solve a lot of my problems.

If anyone could offer any advice I'd be extremely grateful,

Hi Mrfixit,

I have been exploring that possibility, and short of me being able to find a more common replacement engine that's probably what I'll have to do. The unfortunate thing is that it takes 6 weeks for parts to arrive here from the US by sea freight (air freight is hideously expensive) and I was trying to avoid having the machine immobilised for that long as I wouldn't be able to oder what I needed until after the engine was pulled out & dismantled.

Oh well. If everything was easy then anyone could do it :)

I had to repair a couple of the 4P motors and was able to get the parts ok in the USA. Maybe you could have them shipped to you.

Hi Roadtech.

Many thanks for the reply, I greatly appreciate it. I'll certainly give that a try, but at present I'm still finding my feet in the forums and don't yet know how to contact posters directly.

Everything is different from torque converter and trans mount to motor mounts to electrcial & cooling system, a 4P & a 4Y may interchange a little easier, but in the long run of a frustration level & cost you may just want to stay with the 4P. Contact Toyzilla on here by email and he may be able to help shed the light on your problem.
