  1. TD6 head gasket

    Ken, You may have a fuel pressure gauge on the dash, as there is a crimped piece of tubing coming off the pump where a gauge would be. Looks to be disconnected and crimped over on the end of the tubing. On the injectors letting fuel into cylinders, could be some rust or debris from the pump or lines is holding the injector open and letting unpressured and therefore unatomized fuel into chamber. This will cause the "slobbering" or wet stacking. Or the rack may not be coming back into the off position, which will push fuel up to the injectors. Jim.
  2. TD6 head gasket

    Ken, On the diesel in the pump, sounds like the seal on the primary pump is bad. It will allow fuel to enter the pump main housing. If the drive seal on the front of the pump also leaks, it will leak the overfilled diesel down inside the front cover and into the engine crankcase. diluting the engine oil. This is a somewhat common problem with these pumps and the seals have become hard to get. In the last couple of weeks, someone posted some places that still sell the seal kits, or a conversion kit that will work. If you have the timing and gas ready to start the engine, you can crack the fuel throttle while it runs on gas and bleed the injectors at the same time. While it runs on gas, check the pump fuel pressure gauge on the pump to make sure it has enough pressure to fire it off once you switch over to diesel cycle. Jim.

    That looks like the area east of Paso RObles. From the hills and wheat/barley crop. Where are you located? Jim.
  4. td14 cab

    Would like to put a cab on one of my girls, but this one is just too far away. Jim.
  5. TD6 head gasket

    Ken, On the injection pump, there is a petcock on the side of the housing. open petcock and fill until oil comes out then close petcock. IF its been a while since changing, drain old oil and fill as above. Use engine oil. Jim.
  6. Engine Stuck

    Vic. Sorry if I wasnt clear in my description. The 50/50 mix I referred to is acetone/ATF. The draining off of the water in the crankcase is to see how much water got into the engine, usually from rainwater going down the exhaust stack. If the tractor does not have water in the crankcase It may be set up from sitting and the 50/50 mix will work to get down the pistons and rings and get things moving. If you get some water out of the crankcase, you may have a bit more work on your hands. I have drained up to 2 gallons of water out of crawler crankcases. Let us know what you find out. Jim.
  7. Engine Stuck

    Vic, This question comes up often and really depends on how bad the engine is stuck and how long it has been sitting. I would put in the 50/50 mix and let it sit. Loosen the drain plug until water starts to drip. Catch the water in a pan and see how much has collected in the pan. That will give an idea of how much water went thru the engine. You cannot do any harm in putting in the 50/50 mix, but rust and pitting on the cylinder walls and rings can give problems down the road. Good idea to pull valve cover and check to make sure all of the valves are free and moving. Otherwise you risk bending a push rod, breaking a rocker arm and causing more problems. Go easy and let time work for you. Good Luck, Jim.
  8. Little Yellow T6 update

    Thanks guys, I have a clear picture of how the rod and cap are oriented with the camshaft. Jim.
  9. Little Yellow T6 update

    The confusing part is numbers on both sides and some of the caps were installed boss up and some boss down. Jim.
  10. Little Yellow T6 update

    Hi All, I have another question for the gasser engine crowd. What is the rod cap orientation with respect to the square boss on one side of the cap? and how is the rod oriented to the camshaft? open side of rod to cam or away? Not clear in the repair manual. Thanks, Jim.
  11. So I pulled the head on the little yellow T6. Head and valves were clean, no carbon. sleeves and flattop pistons were clean also. Poured some ATF/acetone in the cylinders and next day holes 1,2,3 were dry. miked the sleeve and ID was 4.00 inch so overbore sleeve was installed with new pistons. Pulled pan and pushed up 1-3 rods by hand. #4 needed a couple of taps with a oak dowel and small sledge hammer. #4 rings were tight, so i stuck in a can of solvent overnight and tapped them free next day. (Using a plastic mallet, just light taps around the piston until one end pops up, then just keep tapping until the ring pops up.) Aluminum pistons with cut out skirts. Rod inserts were std. still need to pull mains to check for water damage. Oil pan has some good dents in it that need to be beat out. Water passages are full of rust from running straight water. Valves are OK, but exhaust valves have no margin so will need replaced. Since this engine is the same as used in the Farmall M wheel tractor, parts are plentiful and cheap (at least compared to diesel parts) Stay tuned for more adventures, Jim.
  12. TD6 Dozer/Loader

    Chris, left position on the light switch is the low charge setting, there is no "off" position. You may have a stuck thermostat, which should be checked as its much better to run the diesels at the proper temp and you dont want the wild swings in temp. on these gas/diesel heads. Several of my crawlers have had the fuel pressure gauge replaced with a oil pressure gauge. Your tractor is looking good. Jim.
  13. TD6 Dozer/Loader

    Chris, The track roller seals are different from the upper idlers and there are different styles of seals depending on the vintage of your machine. For light use, I think the corn head grease will work well and solve the leaking seal problem. The OEM rotary light switch is 4 position; low charge rate no lights, high charge rate no lights, low power lights, high power lights. I think I just ran a ground to the mounting bolts on the light bracket where it threads into radiator tank. Jim.
