First post....thanks to Mods for adding me to your forum. I hope to get more immediate help with my L3200HST issue, but also hope this may be a resource for my new gas 520RTV. As a disclaimer, I've posted my tractor issue on a Facebook forum for L-series as well but hope to get as much information as I can to tackle the problem.
First, the 'no start' is very recent. The were sporadic 'no start' when I removed the tractor from winter storage in April of this year, but that appears to have been related to safety switches (no crank) and was rectified by working the switch levers/buttons. The tractor ran fine in May and early June and was used for several hours (turning off and on fine) across a few days of pasture mowing. Then it was parked under some trees out of the sun for about 2 months with no activity. We are pretty high humidity in summer....worse this year were a few deluge rainfalls that the tractor sat out in. After one big storm with wind in early August, needed the tractor to move brush and sawed up limbs. That's when it refused to start,.....turning over, but not kicking in. Then one day recently, I was messing around with it and it jumped to life when I started it. I kept it running for about 15 min., then used it to haul some brush for about 1 hr before parking it alongside the driveway. I figured I would keep working on it there, but it was also a more convenient location for a moving service to retrieve it if need be. That was the last time it started. I've since replaced the fuel filter and in doing so noticed the fuel bowl readily filled, suggesting no problem with flow from the tank. With safety switches positioned to allow starting, it *seems* as though I can feel the fuel shutoff solenoid clicking properly, although I can't say for sure that the plunger is functoining and not sticking internally. I have a replacement solenoid on order, but will just be guessing with that as a fix. What would be the next steps to take for this problem? I have tried to start with the line bleed screw opened but to no avail? What is the best approach to test for fuel getting to cylinders/injectors?
As my knowledge of diesels is limited, is there only one pump that pressurizes the lines to the injectors? Also, the little rocker arm that sits atop the fuel solenoid has a hole in it presumably for manual shut-off of fuel....I think my older grey-market Yanmar has a fuel shut off of this style. Can the L3200HST be modified to use a manual fuel shut off and elminate the electronic solenoid shut-off? Thanks for any help that you can provide!
