I have come to this forum in seek of some help in getting an abandoned FEL up and running for myself on my farm
Unit is a Case 620B XT and I have managed to get engine going, steering - but now working on transmission
I cannot select any gears (forward or Neutral)
Managed to obtain via ebay a workshop manual and electrical manual, and following through tests
I have managed to get through a series of steps but have now found a possible fault
On the Control module, I do not have 24V on pin 25.. Pins 1, 19 and 2 have voltage with key on
About to trace harness wiring, but unsure if this is a direct output to the M valves - or if it is an incoming voltage
If any could assist - would be appreciated
Note all wiring in this unit is in fair condition. FEL has been sitting idle for 5 years and has some severe corrosion
Well I did the removal of spool to the topside after centering assembly removal from below. That top spool area were the dirt/dust shield surrounds has a lot of gouges and non roundness for an effective future seal to say the least. It would chew up the new seal in short order. Also now I can see why it did not want to just drop down through valve casing. With all the deep valley made it has raised the metal surfaces and restricted with a larger diameter. First I am going to reduce the high surfaces, then hopefully add some filler to round smooth for dust shield. I figured I would send a pic or two of this problem. Read More...
No Jim never had any mishaps like that thank goodness.When I ran it everything worked like a charm. With the other email The scoring on the spool at top is horrendous and I am fearful it will damage dirt/dust wipe. So I am looking for an inexpensive way to coat smooth again. Any help will be appreciated. Read More...
I suspect that if the centring pin is forced down with a spring, all you are likely to require is a magnet and a pick to remove it. Wiggling the spool with the magnet there may also work. Use your magnet in the oil feed holes to see if you pick up filings. Check the filters and the magnetic screen in the tank.
Don't force anything, remember the close tolerances.
Was a pump or motor replaced that may have contaminated the system? If you find particulates, you may have to hot flush and filter the entire system. Look for dead spots where oil does not flow well, things can accumulate there and sporadically re-enter the system.
Yes Thanks Jim, I do see some scoring on the outside facing the rear out toward the toothed bucket. I had put a stone rub on the surfaces before starting to drop the spool down and it had no relief. So now I am going to push up on the spool to take out. But first I have to take out the centering spring assembly. I started today but the hex bolt is not accessible for socket to torque it loose. It is deep inside a cupped retainer for the spring fixture. It is cupped so close nothing will grab it to loosen it! Yet. So now I am thinking (lots of wood burning) to push on and against spring retainer cup retainer with driven socket and handle to compress spring to access bolt hexes and go counter-clockwise after hopefully engaging it to loosen. What do you think? Thanks ken Read More...
Rachel: I did not like your response. It may be that you offended me by saying old engines cannot be fixed. This is something I have been doing all my life, and only recently stopped because of retirement. Most heavy duty engines are designed to be repaired. Rebuilding is common place.
Many things could have caused this particular engine to fail because of the rebuild: lack of cleanliness; lack of care during assembly; or even something as simple as not gapping the rings into the cylinders. This could result in a broken ring and lots of oil.
While some manufacturers are making some of their engines as "throw-away" engines, designed to be replaced not rebuilt, to make a blanket insinuation that engines cannot or should not be rebuilt, is foolish. Read More...
Well this is my first o ring replace on the Kontac valve stack without taking fully out and apart. I just want to stop the oil leaking out of control valves. I started to drop out the spool from underneath valves (bottom)and it is not sliding down and out. Is binding about an inch or so after dropping. I am wondering if I should take apart centering spring which is at the bottom of spool and then travel the spool up instead and maybe not have this problem ? This is an 1988 machine. It is an LB620 New Holland. I need some expertise in this repair and hoping some one will give some experience and guidance. Also I can not even get all the parts from MFG. "O" rings they have,,, I especially need the top valve pack seal (harder plastic surroundment.) to keep out the dirt. Any and all help or where to go will be appreciated. Read More...
