Hi guys,
 
This tractor is new to me.  I have two issues....
  • The power director seems to slip in low range.  I noticed the oil is low and my manual says to use 20-20W non-detergent engine oil.  Where am I going to find that?  What is a good substitute?
  • I put a 230 gas engine in this tractor.  It previously had a diesel in it.  I flushed the radiator and put a new thermostat (automotive style that didn't quite match the flapper style a took out).  It also has a new water pump and belts.  All seems to be working correctly.   Anyway the engine temp at high idle stays at 200F.  Any thoughts on if this is normal?

do you know what the temp of the thermostat is? if you put an automotive one in there like you describe the normal automotive thermostats are 195 Deg F so then it would be normal. I believe the correct thermostat would be a lot cooler than that.

Personally I would put the correct one in it.

As far as the PD oil I just use 20W engine oil which can be bought almost everywhere.

Ok...so I put the oil in.
 
When I put it in 4th low with the clutch out it slowly picks up speed.  Gives me the impression that something is slipping.
 
If I put both brakes on, I can stop the tractor.  If it is in 4th High, I can't. 
 
Do I have a problem with the power director low clutch pack?

The thermostat I put in was 180 F.  The temp gets to 200F but doesn't seem to go higher.

Does it have the "snap" when you engage the low side? Might need to be re-shimmed? I have never done this but it does describe it pretty well in the manual. moving shimms around between the low side,high side, and nuetral. I would think you need to move some from the low side to the neutral position to tighten up the low side?

How about the set screw where the PD handle attaches to the shaft? I have seen that screw come loose and they don't get engaged far enough?

Beg borrow or steal an infrared heat gun to check the actual temperature when up and running. Your gauge may be off.
 I wouldn't use the low side of the PD in any gear till you get it fixed.

<groan> not a heat gun.  I hate those things.  They have way more potential for being off than a good mechanical gauge.  You would be better off taking the cap off and just sticking a thermometer in the coolant.

Creek, If you did the kind of work I used to, you would find them indispensable. There's nothing like spending a couple weeks rebuilding and scraping ways on a press and then when you have to assemble it, you can't get to all points to assure proper clearance when adjusting the ways. The gun will let you know right away if a spot is running a little tight.
 Like anything else, there are quality tools and there are cheap tools.

So guys, I am still working on the overheating issue.
 
I bought a thermostat from Agco and put that in.  Still heated to 200-220F.
 
Bought a different water temp guage...same result.
 
Ran the engine, pulled the thermostat casting off and saw the Agco thermostat didn't open in the hot water, put the one from Carquest in the hot housing, it didn't open.  Had one off of a D19 (wrong diameter) so I put that in the hot housing, and it opened a 1/2 inch.
 
Went back to the house and boiled some water and dropped the Agco one in, it didn't open even an 1/8".
 
So.......now I cut the Carquest one apart to take the guts out and reinstalled that.  Tractor doesn't even get up to 120F.
 
How could I have this many bad brand new thermostats?   Any other thoughts on what I am doing wrong?
 
Thanks in advance,
Terry

I never install a NEW thermostat without checking it first.  Also always verify the Temp guage the same way.  After a couple of bouts with thermostats in corvettes, I learned my lesson.

Did you put in a new temp gauge?  Some of the new ones aren't very accurate.

Most problems can be solved with the proper application of high explosives.

Yes, I installed a different temp gauge and it read it exactly the same temp.

So, I bought one more thermostat.  Checked it in boiling water and it opened up.  Installed this...same result.  It is not opening.  I wonder if the casting on the engine is twisting it in some manner that is causing it to bind up....or is cold water on the other side of the thermostat causing it not to open....I'm baffled!

Are you installing the stat with the bulb toward the engine block. Sometimes air can get trapped when you change stats and it might take one time of "over heating " to clear things out. Some stats have a small hole drilled in the flange to keep from trapping air.

Yes, the mass of the thermostat is down and on the "engine" side of the joint.  I like the idea of drilling a small hole in the stamped housing of the thermostat.  That would get hot water to both sides.  I'll give this a try later this week and let you guys know what happens.   Thanks for the advice!

The thermostat I had in there had a bleeder hole in already. 
 
I ended up trying a 165F thermostat and everything works well now.  The gauge now runs in the 180 range.  I can see the water circulating and could tell when the thermostat opened. 
 
It bothers me that the one I got from AGCO didn't work. 
 
Thanks for the help.
