Dead perkins....(ie, help...)

autodoc1 · Dec 31, 2002

Just a Quick and easy test. Spray WD-40 in to the air intake (NOT starting fluid if it has glow plugs) while cranking engine. If it tries to start you have a fuel problem. Look for air leaks in the supply line to pump, check pump pressure, if pressure is low check pump timming. Some have a key way in the pump shaft that may have sheared.

I hope this helps

Sorry late with any more info..

DarinRay : Idiot lights working fine, as far as I know, there is no safety switch OTHER than the need to have the forward/reverse selector in neutral. I have clicked it forward/backward and put back into neutral to be sure.

Amp762: My exhaust flapper was bobbing up & down as I was turning engine over. Other than that, (without spark plugs), how do you check compression? Do I take the injector(s) out and test there?

Bgott: I believe the injection pump is mechanical. I looked at it and there seems to be a housing that either has a belt in it, or since the housing is completely enclosed, I suspect a chain or gear. I am not aware of any solenoid switch (but then, maybe I need to ask my dealer !!)

Autodoc1: Hmm.. wd-40 into air intake... I do not know if this machine has glow plugs. I DO know it starts likity split every time. Probably within just a couple of revolutions.

Thanks again.. Tomorrow (Wednesday) I plan on tinkering to see if I can get it started.

I don't believe that it will have glow plugs. I have never saw a Perkins with plugs. As far as the attachment of the pump, it is all gear. Perkins don't have any chains and I would be suprised if the problem had anything to do with the gears or the pump.

It has a mechanical pump, that doesn't mean it won't have an electrical solenoid. Does the engine shut off when you cut off the key? When it runs, anyway.

If it does, you have a solenoid. If you have to pull a knob to shut it down you probably don't have the solenoid.

I have to pull a knob to kill it. (I know, I just replaced said knob and cable this past summer)

I still recall the first time I ran it and it did not turn off when I "killed" the ignition... ALSO..when the ignition key is turned off, the transmission DIES!!!

seems the transmission is somehow electronically controlled and no key, no go. /w3tcompact/icons/blush.gif

btw, I have made sure the pull knob is NOT in the pulled position

I have made sure the pull knob is NOT in the pulled position 

Sad and embarassing memories as I sat on my tractor, turned the engine over and it failed to start. The mechanic listened then pushed in the kill knob and she started right up. I felt like an idiot.

No solenoid then. Try the WD-40 trick posted above and if it starts I'd then try rigging a small fuel tank to the suction line of the pump.

Try the WD-40 trick posted above 

Roger That!

Will be out tinkering in couple hours!!

Thanks

the WD-40 trick 

Just realized..I have a nice new can lf "Liquid Wrench" and not a drop of WD-40....

Does that make a difference? will LW work as well as WD??

...will LW work as well as WD??...

Maybe not the "exact/same secret recipe"... but should work... /w3tcompact/icons/wink.gif

To be sure... use a shot of ether instead... just don't overdue it.../w3tcompact/icons/blush.gif
