switching to diesel

what is the secret to get a TD6 to switch to diesel on a cold day.

1st thing make sure you have enough #1 fuel in it.

Make sure the engine runs long enough to properly warm up (5-10 min). If it doesn't switch to diesel put back on gas and get rpm up again and try going to diesel again. Repeat going from gas to diesel until it gets the injection pump working so it will run on diesel. The check valve in the pump is probably leaking fuel back to tank.

I also have a TD6. Last winter when we had 2 months of sub-zero weather it started on gas , and I also had a few problems switching over. But I found that I had to run it for 20 minutes or more sometimes. Had to refill the little gas tank while it was running. I know... ultimate no-no. But when you have 2-3 feet of snow to move you get desparate. Had to get to the woodpile. Get it good and hot and it should switch over if everything else is up to snuff. Hard to get it hot with that massive radiator!!! lol

I have run many of them old I H gas start engines . The key to them is to make sure that the fuel filters are changed BEFORE winter , water trap is clean and you have a winter grade fuel in it . Always make sure the starting tank is FULL with a good grade of gas . Start it up and let it run on the gas side till it is warmed up and it will tell ya when that is , as the gas carb is a set speed carb and it will only rev up so far . Make sure that you have oil pressure up shortly after start up on the gas side . As the engine warms up on the gas side the RPM's will start coming upand when she is not reving up anymore then and only them do make the switch . You can start to open up the diesel throttle a little just before you make the switch and it will start to smoke . Then flip the lever and open the throttle about half way , she may complain a little at first but she should take hold then back her down a little around 1/8th to 1/4 throttle and let her run there for a bit to keep warming up . PLaceing a tarp over the rad or and old feed sack will help. if it does not have the summer fan . Once it is done poppen farten then you are ready to go to work. Ah the joys of starting OLD equipment in the winter , i remember them well , you would not believe me if i told you what all we use to do to get stuff running . One other tid bit of info never park your dozer on the dirt in winter , Place wood planks or park it up on old tires and the same with the blade or bucket . Never plow snow with a dozer with tight tracks let them have a little sag as the snow and ice will build up big time and tighten them up a lot more then you want.
