Author	Topic: RUNS FOR APPROX. 10 MIN. THEN LOOSES POWER THEN STALLS.
stevet True Blue Posts: 13 From: Esperance, N.Y. USA Registered: Aug 2004	posted August 08, 2004 00:26 I have a 1962 super dexta which I have owned for 3yrs. now. It's been a great tractor for me for various uses only when I work it hard it tends to overheat. I cleaned out (flushed)the radiator out and pressure washed the fins out which seemed to help a bit but not completly. I then took off the heater pump which I thought may have been restricting the coolant flow but this did not work. For some reason now after starting the tractor after approx. 10 min. it seems to loose power and then stall. After it cools down it seems to run OK for another 10 min. The water temp guage does not even reach half way to the red. After further inspection I felt the hoses and it seemed like there was air in them. I assume this is the problem and am hoping it is not something more serious. Also how con I get the air out of the coolant system? Will the water pump prime itself and blow the bubbles out? Or is there another way to do this. I would appreciate any opinions on this. IP: Logged

If it's working then it seems the tractor isn't overheating and your problem may by coincidental with cleaning up the radiator. Can you verify the reading with a another guage or another type of thermometer? BTW, you're only about 20 miles from me. I have a Dexta I use over in Salisbuy. Just rebuilt the engine this winter. The water temp. is a steady 150 deg. F but it only gets light use. When I refilled the coolant, I just poured it in the radiator. Didn't try to bleed any air. ------------------ don IP: Logged
stevet True Blue Posts: 13 From: Esperance, N.Y. USA Registered: Aug 2004	posted August 08, 2004 14:22 Thanks Don, I guess that is possible. I just pulled off all of the hoses to inspect them and found a pin hole in the upper hose,perhaps it just lost to much water. I orderded new hoses and once I replace then and filler back up i'm hoping all will be well, anyway i'll keep you posted. Just after I purchased the hoses I found another site with the same hoses for 1/2 the price. I guess it really pays to look around. IP: Logged

For example, there's an auto hose that will fit between the pneumatic governor and air clear if you cut 3 inches off each end. The part is considerably less than Ford wants for it. I got good prices on my engine kit and clutch from sources down south that other members had used. ------------------ don IP: Logged
Mtneerdan True Blue Posts: 11 From: Tenn, USA Registered: May 2004	posted August 09, 2004 23:11 A lean fuel mixture will cause a diesel to run high combustion chamber temps. This can result in either an overheated engine, or a severely overheated piston which swells and binds in the bore, causing siezure of the engine. This is a somewhat confusing problem I have experienced in the past. I hope it is not your problem, but it is possible. IP: Logged
tony True Blue Posts: 136 From: carrollton, ga Registered: Sep 2003	posted August 10, 2004 00:10 How did you assess that the mixture was lean? How did you fix it? Would that mean the fuel pump was out of calibration? IP: Logged
Mtneerdan True Blue Posts: 11 From: Tenn, USA Registered: May 2004	posted August 10, 2004 03:12 I took it to a mechanic. He told me what the problem was. Seems like it was an injector, and it was only one cylinder that had the problem. Ended up rebuilding the engine due to scoring in that cylinder. It was an old massey ferguson. Had a perkins engine. That may not even be your problem, and you will need someone with more knowledge than me to tell you how to diagnose it. I just thought I would suggest it, in case you were, perchance, looking for the problem in the wrong area entirely. Good luck with it. Regards, Dan IP: Logged
tractorfix True Blue Posts: 143 From: Uxbridge, Ontario, Canada Registered: Jul 2003	posted August 10, 2004 04:56 You have 2 choices. Either it is getting hot and sticking, or you have restricted fuel flow. This is very common on gas jobs because of the smaller filters they use. On a diesel, I would say to look at the stainer that is pressed into the top of the fuel tap. A very good clue would be if will still turn over once it quits. If it does, you have a fuel supply problem. Also check for a bad lift pump. IP: Logged
stevet True Blue Posts: 13 From: Esperance, N.Y. USA Registered: Aug 2004	posted August 11, 2004 07:02 Thanks for all the input. I was just wondering since I have the coolant hoses off do you think I should replace the water pump or rebuild it? perhaps it quit since there seemed to be air in the hoses after running it a short while. Also can anyone tell me where the thermastat is located I'll replace that as well just in case. IP: Logged
Mark Burgess unregistered	posted August 12, 2004 06:03 The top hose on your radiator leads down to the thermostat. Don, can you remember which car hose works for the air cleaner? Take care. Mark IP: Logged

This also overheats the engine, and might cause the engine to stall. You can check this by removing the thermostat, fill the water to the top so you can see it, then start and let it run, if you see airbubbles coming up pretty fast then its likely you have a leak in the headgasket.

don True Blue Posts: 89 From: Schenectady, New York, USA Registered: Jul 2003	posted August 24, 2004 04:36 Mark This is from a post by Wayne B. from about 2 years ago. You can find it quickly by searching under "Advanced Auto". "Took the part, drove directly to the Advanced Auto Parts store, found a hose with the same bend (C) 70738 and determined that if I cut 3 inches off each end they both would appear identical." ------------------ don IP: Logged

stevet True Blue Posts: 13 From: Esperance, N.Y. USA Registered: Aug 2004	posted August 29, 2004 00:35 Do any of you guys know where I can find a waterpump for this tractor. There does not seem to be a leak in the head gasket and I replaced the hoses which were in bad shape and I replaced the thermastat and loose belt and It seems to run a little while longer before it quits. I do recall a squeeling noise not long before this problem occured and I'm thinking that it may have been the water pump and since it probably needs to be replaced anyway I 'll go that route. Thanks IP: Logged
tractorfix True Blue Posts: 143 From: Uxbridge, Ontario, Canada Registered: Jul 2003	posted August 30, 2004 00:35 When it quits, will it still turn over or is it stuck? Unless there is water pouring out of it, I really don't think you need a water pump. IP: Logged
Jos Cuypers True Blue Posts: 410 From: Tongeren - Belgium Registered: Sep 2002	posted August 30, 2004 17:50 Steve, Are you sure you have a temperature problem ? The 10 minutes sounds familiar to me but I had a complete other issue : FUEL ! To shorten the history : Had sugar in my fuel tank and this did not allow the fuel to flow at enough volume into the fuel-pump. Than after 7 minutes, working on the fuel that is in the pump ,it stalted. Stopping and waiting till the pump (beeing in underpressure now) was refilled and than ready for an other 5 minutes (depending on the RPM !!) and so on. My advice : check your fuel-lines and filter starting to see if the flow is sufficient : Fuel-tank clean => filter on top of the fuel supply tap => fuel line to lift pump => lift pump => line to fuel-filter => fuel filter => line to fuel-pump.

stevet True Blue Posts: 13 From: Esperance, N.Y. USA Registered: Aug 2004	posted August 30, 2004 23:34 It will still turn over after it stalls but it will not stay running until the engine has cooled down again. IP: Logged
tractorfix True Blue Posts: 143 From: Uxbridge, Ontario, Canada Registered: Jul 2003	posted August 31, 2004 03:03 Like I said several posts up, you do not have a cooling problem, it is starving for fuel. The strainer in the tank is a likely culprit. If it still turns over when it quits, it is not a cooling problem. It may also be sucking air. IP: Logged
Jos Cuypers True Blue Posts: 410 From: Tongeren - Belgium Registered: Sep 2002	posted August 31, 2004 13:02 Steve, I am 99% sure it will be your fuel-supply-system. AS when temperaure would be the problem, the engine would not turn over at all and ready for revision. Regards Jos IP: Logged
Brian Rules All Things Blue Posts: 2824 From: United Kingdom Registered: Feb 2002	posted August 31, 2004 18:28 Just a thought. Try running the tractor with no diesel cap. Brian IP: Logged
tractorfix True Blue Posts: 143 From: Uxbridge, Ontario, Canada Registered: Jul 2003	posted September 01, 2004 04:17 Excellent point Brian. I had a car that did that. A 1/64 drill solved the problem. IP: Logged
