no temp gauge for the hyd oil
===========================
power steering fluid, hydrulic oil for front loader and back hoe, and the tranmission all use the exact same type of oil.
the shop manual i have for it, shows a tranmission filter just off to the side of it, and then an inlet/outlet line that run all the way up to the front of the tractor. and when looking myself to double check things. it looks like the same lines for the loader and back hoe all run into the same cooler.
there are 2 pumps one standard pump to run front loader and backhoe. ((located up in the front i want to say just below the radiator, (would need to double check manual)) and then the tranmission has a built in pump into it per say.
when you say there should be 2 different oil coolers. one for the loader/backhoe and other for tranmission. i can completely understand. but when i am physically looking at things and then at manual. i am just not seeing 2 different coolers. ((not counting the radiator for the engine)) and the manual doesn't make a distenction between the 2 coolers when looking at pictures.
Vbelt for the fan, it broke last year. thankfully someone had it apart before. and zip tied a new belt around the shaft and stuffed it away. for when the old belt broke. so i didn't have to competely tear off the entire front end. to replace the vbelt.
fan runs, altanator runs like it should. no sqealing, right tightness. ((forget how much flex it suppose to have, would need to double check the book))
============================
next thing.
i can rev up to 3/4 engine speed when going at it with the backhoe. granted 3/4 engine speed after 3 hours my rear, shoulders and arms, is ready for a break, but temp gauge for engine stays the same. and never gets to red line.
if i let the tractor just set there, at idle speed. there is no temperature change for the engine. heck i generally let it run for 15 minutes to warm up when initially started and longer in zero digit cold weather. (has block heater) then let it run for 15 minutes to cool down at idle speed. and there is a change in the gauge. most of the time. pending on how long, hard i ran it.
==============================
next thing PROBLEM A
if i run the tractor (reverse / forward) or work the tranmission. say not paying attention and to high of gear for what i was doing. it would over heat. that would be no brainer, *looks guilty* when i first got it, and started playing, it took a couple times to get use to the gears. and i did get the temp gauge for engine warm, by running into high of gear for the load i had and speed i wanted to go. no guage for tranmission, so i can't not say how hot it got.
but say running 2nd gear and at 3/4 throttle and going for 1 mile over flat ground, it would want to overheat and i did smell antifreeze once boiling out. (not doing anything grading, working bucket or backhoe (nothing)) just driving.
coldest day of this year not sure how cold it was low single digit or below zero. worked the transmission plowing snow. it took a couple hours before i started seeing the temp gauge for the engine to start to rise, once it did over the next hour 2 to 3 hours it slowly rised. if i went another hour i could of had a boil over and been smelling antifreeze.
PROBLEM A, to me would suggest tranmission is overheating. since i can run engine at 3/4 throttle non stop while working backhoe. granted not a constant load on the engine like the tranmission would have.
PROBLEM A, when i removed the old filter. the filter had a hard crusted hyd oil clear around it. it was almost like a rock in strengh. but looked waxy and clear. like it was hyd oil. but something for what ever reason caused it to form into a solid. kinda like greese when ya put it in a frying pan it is a liquid but when when it cools down it is hard substance. granted the stuff on the filter was much harder.
1st grear = digging with front loader bucket
2nd gear = back dragging / grading / pushing snow
3rd gear = load in bucket going down a hill or on flat terrain.
4th gear = road gear. requires me to be on flat surface. to even use. and all in all i doubt i will ever use. to 20mph to fast. for what i need to do. and way to bouncy.
there is no low or high gears. it does have shuttle shift. so same speed either forward or reverse.
===================
PROBLEM B
when i initally got the 555C it work nothing was lighting up in cab. after some use the BY pass for the hyd filter for loader/backhoe came on. it had same like waxy looking hyd oil look that was hard like a rock around it. for temp doing i nocked the stuff off. put filter back on. and light went out. the light came back on next time i used it or there after. (was waiting for new filter or was shorter after i put new filter on), by pass valve for hyd filter for the loader / backhoe came on. took filter off, and there was another chunk of this waxy looking stuff made out of hyd oil that was hard as a rock. stuck to the outside of the filter. removed put back on, the by pass valve for that filter, has never came back on.
shortly then after i felt the chunk of something go through the one rigger. when i say felt. there is a "thump" and through the vibrations. and looking at the lines to the cylinder on out to the outrigger. there is something in the given line.
after the "thump" everything is fine for some time. till what ever it is works it way back into the line and back into the valve.
PROBLEM B. this "thump" or what ever it is. is worse when the oil is cool and less when oil is hot. leading me to believe that it is a chunk of this hard waxy hyd oil stuff. more so. i can tell when the chunk of what ever it is stuck in a metal hose vs a rubber hose. due to it is harder to move the valve.
=========================
at my current line of thinking is. what ever has caused this hard waxy oil stuff to form around the old filters (for loader/backhoe) and for the (tranmission). is most likely a build up of "something" what ever it is. is causing the pipes / hoses and areas were the oil flows to in idea clog things up else were in the system. not completely stoping the flow but instead of having say 1/2" inside diameter pipe, with this stuff clogging things up results in having a 1/4" inside diameter pipe.
smaller size piping with same amount of volume of oil flowing through it = higher GPM through given areas and more friction, more friction = more heat. more heat = things start to overheat.
========================
then again it could be 2 different problems. just something in the one outrigger line. and something is up with the tranmission causing it to overheat. resulting in the engine over heating.
