I may do that when I went to go buy new studs and some other bolts the service manager an I go to talking about removing bolts and talking about tractors and such he mentioned those welding rods designed for removing broken bolts gave me a couple samples rods to try out next time I need to remove a broken bolt and gave me a price as they sell them by the pound for 30 bucks a pound also mentioned the Nano magnets said he had some that could be attached to the drain plug by drilling and tapping the plug bolt to attach the magnet or by epoxy so it is something I will do to be on the safer side of things but for now I need to get the Selectamatic hydraulic valve body back together which is a bit more complicated than expected
plus a special tool needing to be made to adjust it correctly... lots of fun today cleaning it all up nice and clean and then more not so fun in the assembly

You know that if you make the tool, you will never need it again.:devil:

+1 on that the tool I did a search for and from what I gather you have to make it according to the article I found searching for the tool.... so making it verses buying it and the likelihood of never using it making it is prolly the way to go.... oddly it just looks like a basic curtain rod clip just bigger but needs to be precise on the measurement and bend not to complicated by any means as the article gives you the dimensions... with a small drawing of it..

well last couple days was cold and constant rain here so not much this old body could do joints were a bit stiff and hard to get move in.... these things happen when ya are older and a bit broken in two.....

But today is a much nicer day mobility is a bit better so I'm out to get some things done....

An So I thought :mad:

I get some of the parts and housings cleaned up so I could start assembling the tractor but decided they needed to be painted first so I set every thing up on my paint stands.... all is good and moving rite along when the enviable happens.... I hear a ka~thunk and turn around to see the 85 lb. axle housing on the ground heavy enough to sink a bit in to the sand so now the paint not quite dry but in middle stages of tackiness wet enough to grab on to as much sand as it could.... So now I have to re-strip it and do it again.... but wondering how and who pulled the stand pins that caused it to collapse :confused: as I never pull the pins I just leave the stands because I use them often odd how the damdest things just grow legs and walk off
knowing someone pulled them because they had enough paint and crap on them you would need pliers to work em out.....

Sometimes you just wonder why you even crawled out of bed in the morning.... an so back to square one :(

So for the last few hours I've been wrestling with the hydraulic valve on this tractor.... There is a tube that goes in to the housing that provides fluid from the pump to the valve and is held in place by a thread and lock nut from out side the axle housing but will not stay in place when your trying to reassemble the valve back in to the axle housing and you can only fish it in through a small port in front that the lift lever and draft control bolt on to

Man this thing is a big pain in the ass...…….But I finally got it in and secured to the valve.... I've been frustrated by some things but this just frustrated the tar out of me... so giving up for the night and gonna get back at it tomorrow and see if I can finish it all up and have it buttoned up for pick up... another day and another dollar lost....;)

Was reading your post on this in what did you do today. It might be worth a shot to take a screw driver or a heel bar (or a stethoscope ) and put the end on the different valve bodies in the system and listen to what's going on. I had a main pressure relief valve bypassing on a truck packer body one time I could not pick up on with all the engine noise and whatnot. Stuck my ear to the end of long screwdriver with the tip on the relief valvebody the SOB was shrieking like a Banshee. It had a little sliver of metal caught in the relief valve keeping it from closing back up. Couldn't hear it but it was keeping system pressure down enough to screw up the entire packing cycle. Just a thought as you chase shit down.

I went through all that and don't hear anything....

I am frustrated to no end with this one so I need to sit back and collectively get my head together and start from the beginning and go back through it which is a hell of a lot of work to do but it will need to be done...

Just when I think it will be a simple fix it just gets more complicated pain in the ass must be from getting old and tired either way its back to square one again....:(

OK, been there done that and yes I have the hard earned T-shirt. What is the system normal working pressure and where can you T in a gauge to see WTF is going on??? Ideally, you need to get a handle on pressure and volume. Pressure X GPM = work getting done. You need a concrete picture as to where to look. If you can pull 2000Lbs @ 20GPM you need to tear into the control circuit just my 2 cents .

Ill have to look and see what the actual working pressure is but it was 1800 at the auxiliary out put an according to the online book it should have 1 imperial gallon for 60 seconds of run time coming out of the return at the pipe on the TCU valve and appears I have that but also if no lift it could be the pipe going over to the lift piston fractured which means ripping the diff and axles apart just to get to it either way its no easy task

This thing has got me so stressed out all I see in my head when I try to sleep is that dam TCU valve and schematic sort of nightmarish shit...

kind of like a flash back from many years back... when I worked 3000 head of sheep for the first time in my life took me a couple of weeks to be able to close my eyes and fall asleep with out waking up in a cold panic sweat cause all I could hear and see in my head was those 3000 dam sheep jumping burring and bah-ing and a saddle sore ass to go with it... for a month

Anyway today is a new day of frustration just like the sheep I can't shoot the dam thing because it's stressing me out... I just got to figure out the problem an get the job done...

Walk away......

For awhile, do something else for a few hours or days.... Sometimes it helps.
I had a tractor that would not start in wet or rainy weather, after a week of running the wiring. I was stumped. No problem could be found. Fixing it became a mission, the owner, wanting it back, it setting there snearing at me, and not having a clue as what was wrong and how to fix it. I sent the tractor back with no charge for the work. It ended up in three seperate shops before landing back here, fifteen minutes with a garden sprayer, I had found the problem replaced the the low oil pressure switch and it will start in a monsoon now.
