Still unable to start Engine! I have removed the Head to re establish TDC. I also removed the injector pump to re reinspected by the folks who rebuilt it,they say the pump is good and works fine they checked the pressure out put and it is within spec. My next Question is what type of service needs to be done on the energy cells ? I have removed the 3 parts but without a special tool am unable to remove the body. I am going to try to lap the body and plug surfaces together instead of separate on a glass surface as recommended. Is this O K? Also The folks who rebuilt the pump stated that because this is not aglow plug style engine that i must always use the manifold heater as it basically starts a fire in the intake to ignite the fuel? true or false? Thanks

My husband just rebuilt our oliver 1800. After reading your previous posts, and the DTC problem, I told my hubby about that. He's a good mechanic, and was CERTAIN he had it right, but it wouldn't start, so that was the first thing he checked. It was wrong (very hard to tell) and he reset it, but STILL wouldn't start. Checked again, and turns out somehow he had got the timing off AGAIN and it still was 180deg off (lots of cussing at this point). He very carefully reset it, and then it started on the first crank.

Hope you get your baby working soon! Cathy

On the fire in the intake I would have disagreed also until I saw it happen on a Perkins I was working on. It had a small fuel line that sprayed fuel on the glow coil when cranking, It had a wire to it to shut the fuel off when you stopped cranking. It would ignite the instant the spray would start.

You two guys are talking about 2 different systems. The Fiats from the 55 series and later used the CAV thermostart system which did burn fuel in the manifold. The Oliver built tractors used strictly an air preheater.

My tractor is a White Industrial 2-63 with the Oliver diesel ,same one used in the 1550,1555 & Super 77 based on what I was told? I have a 1550/1555 manual and everything engine wise is identical! As far as finding TDC i used the piston stop with degree wheel method. I mounted a bolt on a bar over #1 cylinder on the compression stroke and rotated the crank forward to the stop read the degree then backwards to the stop read the degree then split the 2 and set themto the same degree on the wheel and turned the crank forward to 0

Sorry to bother this discussion but I must comment.

You are NOT starting a fire in the intake manifold. You are heating the air before it enters into the cylinder as an aid to the heating that occurs on compression.

Your manual will tell you if it doesn't start within 15 seconds to use the preheater.

First of all do you get any kind of smoke when you try to start the engine. When you checked for #1 TDC, how did you check it was not TDC number 6. Both pistons come up together so you need somewhere to check the valves.

I had been getting gray smoke ! The timing was set by watching #1 intake close,then bringing piston to top. Also is there any way to tell zero on the fly wheel? My timing strip is non existant.

On the old diesels there is no timeing strip.They have tdc and fp(fireing point)which is 28 degrees BEFORE tdc.

I forgot to ask you, what method and procedure did you use to find EXACT TDC.
