520xi shutting off

Recommended Posts

Cee245

Hi everyone,

We have a 2002 520xi with about 500hrs we recently bought.

While mowing the other day, it would just shut down and after waiting about 10 minutes it started and ran good until finished mowing. 

Here's my and Dads plan... 

Already changed oil and filter.

 

We will replace all fuel line and filter. New plugs. And clean fuel tank and continue using 91 octane ethanol free gas from local Country Fair.

Clean carburetor.

 

Any other obvious things we should do?

 

Thanks Cory 

 

The newer 520xi is on the left.

Mine was doing the same thing Cory, Turned out to be a bad Ignition switch.  Mine would sometimes die and then start again.  Sometimes it had to "cool off" a bit.  It always seemed to quit just as the tractor was getting up to normal operating temperature.

 

Too bad Toro really places a very high value on those switches.

Thanks @Kurt-NEPA!

If the maintenance that we do to it does not fix it, then I could try swapping out the ignition switch. Thanks for the idea

@Kurt-NEPA

Is the switch your talking about part number 62-7770 "key ignition". Or the  92-6785 "switch ignition"

or am I way off in the part number?

I replaced 92-6785.  The ignition switch.

 

62-7770 is just the key itself.

 

My switch came with key.

Lol, I seen that the 62-7770 is just the key after I posted. 

The switch I've found is expensive at $45 but I was worried it would be stupid expensive... like 200 or something.

That's a good price,  I think I paid about $65 from Toro.

Ok, we replaced gas line and filter, new plugs, air filter so far. It is still shutting down after about 10min or when it gets up to operating temp. It will start after being off and run well and then **** down again. 

Seems like a heat issue affecting a sensor/relay or something. 

 

Thanks Cory 

 

@kurt-nepa, I haven't tried to change the ignition yet that you mentioned.

You might also consider troubleshooting the coil/ignition trigger module circuit. They tend to go "open" when they warm up -- which will kill the ignition. Once the affected part cools off, the circuit closes and you can run it again... until the affected part warms up and the circuit opens again.

Update:

Big chunks of plastic should NOT be in a newly cleaned fuel tank!

 

We worked on this tractor a little bit at a time. And I may not have kept a close enough eye on the kids.

 

Replaced fuel lines, carb clean, plugs ect... turns out that the problem  is that I pulled the gas tank filter (again)  and right then I knew what the problem was.

 

I have young kids! Hahaha

 

Found lots of these Lego parts and other junk.   

 

Conclusion for tonight is after working through that, after getting everything back together (I think) it ran flawlessly for 30 minutes!

Sorry be so long in answering.  Yes, I did get a new ignition switch from Toro. Solved my problems.

 

Great to hear you found the toys. I love simple, but strange solutions.
