The year 1970 started with Serial No 66A 08261 and ended with 66A 09584 so your D9 would have been built in the Spring of that year, while the injector pump is off it might be worth having a look at the camshaft that is "Just a Look" tctractors

Here is the link to a new video showing what is going on with the old girl..... Let me know what you think.... This was of course prior to me taking off the Injection Pump....

After watching the video, it is trying ti fire on a small amount of fuel, should be clouds of white if not firing and same volumes of black if firing and it is producing neither. I am with TC tractors and starting to wonder about the fuel pump camshaft, maybe cam bearing failure or something along those lines.

Thanks for looking at the video.... So am I correct in what I did meaning the injection pump??? She was bled multiple times... At the injectors... I put a set of new nozzles in her and still the same... To me and my ear she just does not seem to be getting enough fuel to the cylinders... Plenty of heat from the glow plugs... I dont feel that is an issue anymore... All new as stated in video...

When you say cam bearing are you talking in the head or in the injector pump??? Thanks for your help.... It is very much appreciated...

I am talking fuel pump camshaft, not knowing the full history of what transpired when x years ago the tractor was shut down and not start again etc, I begin to think that there is a failure somewhere. I have had fuel pump camshaft bearings fail, another thought is a broken camshaft, sorry I am not familiar with D9G's, mainly D8H and D8k tractors, their fuel injection systems are somewhat different to the D9.

I think if you can get the right information posted here OM, edb and TC tractors will sort out the problem. It is a pity there is now so many threads and all the information has got scattered, much better to keep it in the one place.

Can you take a look at the video and let me know what you think... Wombat stated you and a couple others on the forums can sort this kinda of thing out... Appreciate it immensely...

Spray some starting fluid in that thing or try a gas soaked rag in the air filter housing around that safety filter......its about to go!

About the only things that could go wrong with the fuel pump housing would cause a decrease in lift of the plungers. I thought it was a little odd that you seem to have 3 up front that spurt significantly less fuel than the 3 at the rear. Wondering if you might have someone check the lift on all 6 and compare to specs. Seems like a bad bearing or bushing would be obvious by just shaking the camshaft but a worn cam lobe (or 3) wouldn't be so obvious.

All that being said, I think your engine probably is really badly worn or has stuck rings from sitting. The amount of blow by smoke coming out the open governor side cover ??? or wherever on the left side is concerning. I expect to see some blow by on a running engine but not on a cranking one.

I've got a smaller D318 engine I've worked on quite a bit in the shop. It's a "good runner" I bought about 15 years ago and have had in the shed since. About 5 years ago it fell over on the dirt floor so the oil has been up in the cylinders since that time. I figured that was a good thing. Last year I got it out, turned it over and started swapping parts off the engine it's replacing to get it going. Had to swap the injection pumps and governor, clutch housing, flywheel and pony motor, fuel lift pump, water pump etc. While I had the injection pumps off, I set the lifter heights to spec, also ran the valve clearances etc. Anyway, with the pony motor, I can get it to smoke but it runs only on starting fluid. I think it's just too worn out or rings have stuck while it was sitting. I've given up on it for the last year, but ill get back to it after harvest this winter and see if I might have done something wrong that's preventing it running. Hopefully I won't make the same mistake twice.

You haven't given us a history on this tractor other than something about 3 years ago. It may be like my good runner D318! After all, buying a machine you haven't seen run is like the old saying, "watch out buying a pig in a poke". Same goes for any machine that "was running when I parked it X years ago! Even the ones with a hole in the side of the block were likely running when they were shut down and parked.

D2-5J's, D6-9U's, D318 and D333 power units, 12E-99E grader, 922B & 944A wheel loaders, D330C generator set, DW20 water tanker and a bunch of Jersey cows to take care of in my spare time:D

The dozer was rebuilt 1400 hours ago by Hawthorne in Hawaii according to the previous owner.... When replacing the nozzles as part of the injectors you could see anti seize that was still newer... In addition the Injection Pump gasket when taken off appears to be newer as well... I believe the engine was rebuilt just by what I have seen so far... The previous owner as stated had a very large construction company and a ton of machines and this was parked and not used just the newer machines... The undercarriage is all new and alone would be expensive to replace. The engine Has a ton of dirt and has not been degreased in years... I had the governor cover and the injection cover and the other two panels off and some of that smoke was from oil dripping on the starter with the covers off....

It could be stuck rings so I have put in some mystery oil awhile back into the glow plugs and cranked her with the glow plugs off to prevent hydrolock.... In addition, I just dont feel she is getting close to the fuel she needs... Can it be compression of course... But there should be a lot more smoke... I saw the same thing on the video I posted on the rack.... It was a tough start always prior to this according to the original owner... All things are pointing in my opinion to the IP....

I have tried starting fluid and it knocks sometimes but not always....

Thanks for your help....

The one topic that has not been discussed is the timing of the injection pump camshaft.
Worth checking.....do you have a service manual?

A compressed air leak down test would solve the compression question. Get a 1P5569 nozzle replacement with through hole for the test. This method is a lot easier on starters than running compression tests. Mounting a nozzle removed from the cylinder and reconnected to an injector line as suggested is still a viable test.

When running a log manifold with six open taps, the openings at the blanked end are going to squirt more liquid. (reference fuel squirting)

You can forget about starting technique issues at this point and serious effort needs to be spent on trouble shooting.

Somewhere in this mess I thought you were asking about gaskets for the injection pump.
Depending on how you took things apart it would seem you need a 3S5453 gasket for the adapter end and a 5H5770 for the bottom of the adapter. The drive end gasket is a 5H4470.

Yes, I have a Service manual....

Where you able to look over the video?

I have some people thinking it could be the camshaft of fuel pump or bearing?

I did not see in the service book how to perform compression test;;;
