Thread: lpg forklift doesn't want to run.

In an old D series Ford 300 petrol motor on gas I had, I used to pull the the gas converter apart and clean the honeycone goop from the diaphragm and gauze filter then it would be happy for a while. Just my experience, also coolant had to full.

Yeah, the local place has told him it needs a new converter. But I like to rule stuff out first, and that doesn't make sense to me..... I thought about ringing my uncle or grandfather .... But I know what my grandfather would say "check the basics, first .... always the basics .... before you get technical and start pulling things to bits .... have you checked the basics?".....

so i whipped the top of the dizzie off, found burnt closed up points .... I can't understand how in the hell it was running at all. So I cleaned the points and gapped them... cleaned up the rotor button and cap as well as I could with a screwdriver ..... and she burst straight to life........ Yep, just like my grandfather says "basics first .... you have to check the basics first". Which is very strange, 'cos the damn thing ran fine when it was cold. It must have just completely closed the points as it warmed ( and it DID have spark when I pull the coil lead and checked .... bizarre or what).

thanks again
Shane.

Awesome and easy fix gotta love the old days lol

forklifts must be the most hopeless invention ever made. I finally managed to get it back onto the drive. I've just noticed it is now bogged on the drive one back wheel being slightlly off the edge of the drive ... so it is now uselessly bogged. It has quite large drive wheels, so its amazingly how useless it really is. So much for the idea of being able to use it beside the shed. Its really soft there, yet the thing can't even move itself on a drive that fully loaded dump trucks don't even mark

They're not deigned to drive on anything except firm surfaces. like loading bays, inside factories and have solid tyres for that purpose. There are 4x4 forklifts though.

They are not offroad vehicles especially that little 1.5T job you've got.
For that work you'd want a set of tynes on that tractor or a monitou type machine.

I got a 2.5T fork bogged on a field day site once. Snatch strap and a fully loaded Holden Colorado couldn't even move it. Took a large tractor to get it out eventually.
The front drive wheels are esentially locked- no suspension on them- just a solid mounted 15" diff and solid non-compliant tyres.
The steer wheels are usually hydro steer, and the only suspension they have is a middle pivot point common for the two wheels on a beam axle which move up and down with small travel, on the same plane. This is how the 'triangle of stability' is considered for forklift stability when carrying loads.
Forklifts are are bloody stout little units- deceivingly heavy. a 2.5T fork (standard size) can be easily north of 4.5T kerb weight. Since the front wheels are the fulcrum of the lifting lever, if you want to lift 2.5T on the forks at the 600mm load centre, then you need 2.5T of weight behind those front drive wheels just to stop the thing tipping forward- never mind things like momentum for emergency braking etc. Most of this weight is in the counterbalance which is right above the two small steer wheels. So there is an incredible amount of weight with a small contact patch on those two 12" tyres at the rear. Plus when you steer to get un-stuck, you just digs in more. It's diminishing returns by that point- you get a little stuck, then proper stuck.

TL;DR stuff gets interesting quick when you have a fork and soft ground. Don't ask me how I know...

I think its 2.5ton ... maybe 2.75 ... it looks like a dinky little childs toy.

Its not very bogged, but it can't be moved. i tried to drag it onto some ramps so it wouldn't sink any further .... But there is just no way.

its one sweet little forklift. It'll need to wait until the middle of summer before he can moved from here. this is what trying to move it with a 2ton tractor with the diff lock in managed. I guess he doesn't need to worry about anyone stealing it .... or it getting crashed into by poeple parking cars ( nothing is going to hurt that thing.... I can't think of anything short of a tank that would be more indestructable).

Could you lift the counterbalance using the 3PL on the tractor somehow, then drive the FLT forward? It would probably go a long way to getting it unstuck. I've never had one off, but apparently it's a few very large bolts that hold it on, and it sits on pins at the other mounting point.
