have someone watch the drip as you use one function at a time to see if you can tell when there is an increase in the frequency of the drip. If you can discern which function increases the drip flow that is a start. If by that you can't figure out which hose it is, then jog that function and watch the hoses you might be able to see which hose it is when it flexes when pressure hits it. If you still haven't figured it out then go to the cylinder that you are operating when the leak increases and follow the hoses back to the tunnel. If the leak increases when you extend the cylinder then the leak is the bottom hose on the cylinder if it is when you retract the cylinder then it is the top hose. if while following it back it comes to a valve then the hose that feeds that valve that goes through the tunnel is probably the one. Sometimes I have seen the hoses taken loose one at a time and pulled back and inspected for breaks or abrassions. Don't pull the hose ends back into the tunnel covering. Using the old hose to pull the new hose in is a good idea, After you have fixed the leak don't throw the old hose away if you can store it, you can use it as the third hose at a later time to pull another leaking hose out so you can measure it and get the same length back. I try to stay with the same length hose and try to rout it back in the same position as it was taken out. The only time i wouldn't do this if the hose looks like it had gotten pinched someway in the normal use of the machine. If the hose is frayed from rubbing then try to locate the place where the rubbing took place on the machine and see if there is a sharp edge that the hose rubs against and see if you can remedy that. It would be nice to have a spare hose of each size and length that is on your machine that way it would eliminate the down time of having to go get a new hose just put the spare on and at a later time you could restock your spare hose.woodlandfarms said:Thanks for all the great info. I am pretty sure I have a slow drip in my tunnel. Man, that did not sound good.. Hope everyone gets what I mean. Now the question is how to find which is the offending hose.
I kinda figured out what is going on with my PT. Its age is unknown. It is known that the engine was new in 2004 and then the tractor was set outside to rot with the new engine.
I am thinking that all of those seals and hoses have rotted away, and that it did not show up when PT went through the machine, but now with 40 hours on it the hoses and seals are starting to fail.
Kinda a big bummer as I would think PT would have known this and just replaced these cheap gaskets and such. But whatever, still have a great tractor at a good price...
