My John Deere 310C Dash Light for the hyd. Filter (yellow) stays on when cold.
Not sure what to make of this problem; (In short) the dash board yellow light indicating a hyd. filter issue comes on with cold starts. more so in the Winter, during the Summer it does not stay on as long, then as the machine reaches operating temp it fades away from intermittently coming on, meaning with low idle light is off, raise idle a bit it comes on, when it nears operating temp less and less light until it reaches no more light.
I've been using the machine like this for a little while, but I wanted to figure this out in case I'm doing damage some how, I go on and explain more in detail with a longer story about this issue below.
I took apart 3 Hydraulic Filters after several operating hours on each filter, I'll guess between 3 to 8 hours on each filter I took apart, so I wanted to get a good look at each filter paper element to see if there was any flakes of shinny metal, I used a very strong magna-fine glass to get a deep look into the filter paper element and found nothing, I also looked for non-shinney metal fragments in the filter paper, nothing, it all looked clean as can be, just a little bit of a dark soot like color in the filter, but for the most part fluid could clearly pass through it very easy, so not sure why the yellow hyd filter warning light?
It is common for the switch that sets off the filter light to go bad and not work properly?
I thought about something mechanical having gone bad putting metal flakes into the filter clogging it, this is why I took apart 3 filters, I never seen what a filter would look like when it does capture metal fragments? is it very obvious to see? so I'm not sure if this is hard to detect at first.
The hyd pump seems fine, everything works, perhaps the hyd pump could be a little weak because at times the stabilizers can use some help, but other than that everything else works fine.
I should make a sound file for people to listen to this unit operate, because ever since I got the machine I've always heard the sound of the hyd fluid flowing and the pump operating. I should have a mechanic listen to it because I might not have the ear for detecting a good sound from a bad.
I have a few hyd pistons what are slowly leaking from what looks to be age, one more so than the rest.
This is why I took the hyd filters apart thinking perhaps something like the hyd pump could be on its way out clogging each of the filters I put on, because every time I put a new filter on it corrects the dash light from staying on for a little while, then things are working properly and it goes right back to the filters dash light coming back on.
Anybody have any input as to whats can be going on with this? can I really be missing some kind of fragments clogging the filter I'm not seeing? but I swear the paper in the filter looks great.
I'm yet to study this in more detail, like the hyd filter switch and if it can be cleaned?
All input is appreciated,
Sincerely,
Joe
