JD 4100 quit today. Fuel problem?

[mikenmichele]

Hi, forgive me for being less then intelligent with a diesel engine. I was snowblowing today and my 4100 just quit. It will crank etc but no start. I think It might be fuel related but unsure how to check it. I was going to pull glass filter to see if anything was in it because it does not look like anything is in there at all actually. How would I diagnose this? Its stuck in the middle of my driveway LOL Thanks!

Does the 4100 have a drain for the fuel tank? Mine on the 4310 is on the right side just up from the hydro pedals. If the fuel gels, this is where mine plugs first. I take a propane torch. Like the ones used for sweating pipe. I heat the area around the valve. Carefully! the valve and tank are plastic. Hit it with a little heat, try to start it, heat and start. I keep doing until it runs.

Hi and thanks for the reply! I found the problem. I took the filter bowl down and the filter was full of frozen water. Thawed it out, blew it out(dont have access to a new one today) and while the bowl was off, drained some more fuel to be sure there was no water. Been snowblowing for the past hour and no issues. Guess I need to drain that once and a while lol. Im glad it was a simple fix.

Watch if night temps go below 10 F. Had it happen one winter here 2 or 3 years ago. Had some wax particles drop out and plug the outlet from the fuel tank on my JD 4010. Had to siphon out the tank and use a fish tool to get the wax particles out.

Mike - use a quality Winter fuel additive, if you aren't already. Ex. Stanadyne, OptiLube XPD, Redline etc....

And yes, you need to keep an eye on, and drain, the water separator :thumbsup:

Also consider getting something like a Mr. Funnel, or equivalent, that will filter water from fuel - meaning for when you are filling the tank.

Thanks! Didnt know a funnel was made that separated water from fuel? Thats a great idea although have you seen much water in fuel straight from the pump? I though it maybe came from condensation or when it rained and I left it outside.

I normally don't have a big problem with my diesel source, as it's a very high volume station.

Keep in mind though, condensation can happen inside fuel cans too, not just the tractor tank.

Until you get a handle on exactly where the water is coming from, a Mr Funnel (or equiv.) is a bit of cheap insurance. Also handy if you are fuelling in dusty conditions too.
