question about oil in injection cam housing?

The injector pump housing carries it's own oil. Take the slotted head cap off that's on the side and fill to the top with 30 wt oil.

As for the clutch housing, there should be a square headed plug on the side of the housing about half way up from the bottom. Take the plug out on the top (the one you can adjust the clutch through), fill to where oil starts to seep out of the hole on the side and that's it.

If the clutch drags a bit when engaging the pinion gear you might try ATF instead of the recommended 30 wt oil.

Also, make sure you check that oil in the injection pump prior to each use, especially after sitting awhile. There is only about a quart of oil in there and you will never know if it leaks throught the acces. drive seal and into the engine. Once it is gone you governor will sieze up and the gear on the end of the camshaft that drives the governor will bend the end of the shaft. I know this from first hand experience. They say to check the oil after like 240 hours. Way too long on the old machines that might have a 50 year old seal. It was a costly repair and much downtime. I found out way too much about that pump that I didn't want to know.

Thanks to you all--is the governor housing oiled from this injector housing oil or is something else involved? I had a leak at the seal in the governor housing where the throttle linkage enters--replaced the seal--still have some small leakage. Could the main crankcase breather be involved or are we talking separate systems here? Thanks Vailvalley59

Yes, the governor gets it's lube from the injector pump sump and no, the engine breather is not involved as the engine and injector pump systems are separate.

I don't know anything about the pumps themselves or the mexican reufurbishing facility, If diesel is in the crankcase of the injection pump it could very well be coming from the individual pumps, i would think ther would be a bad seal somewhere in there. another possible source might be the transfer pump seal, i'm not sure how it is driven but i would assume it is driven from the injector pump shaft if that seal were to fail, it could pump fuel into the injection pump. Someone please correct me if i am wrong on this one.

If the engine is slobbering and misfiring there are a few possible causes, the first one to be checked should be the injectors, it is possible that an injector is bad and overfueling a cylinder causing the slobber and miss. Does it change under load?

another primary cause of diesel engines slobbering (but doesn't always create a miss in the engine) is having a poor thermostat or running an engine with the thermostats removed, the engine cannot reach it's designed operating temperature and carbon starts to build up in the rings, pistons, combustion chambers and valves. I have seen many old diesel engines clean right up after replacing bad thermostats and then giving them a work out. A person can also use an oil additive called RISLONE available at any parts supplier to help clean up stuck rings and carbon deposits and excessive oil consumption. you have to change your filters more often when using rislone as it will clean the whole crankcase.
