I will do that. Easy to check, as you say!
Lots of fancy ideas! see if your oil filter has a check valve in it maybe. I'd pull the oil pressure sensor, take a quart bottle of oil with a gear lube spout on it, stuff the spout into the sensor hole and stab a little hole in the bottom of the oil bottle, put the blow gun in there and give it a little puff until it kinda rounds out nicely.
I've been following this thread and I really like Steves outlook on things, seems like a postive type of guy. Me being a realist though I think it might be time to get a good local diesel mechsnic out for the startup. I wouldn't think he had to be a dozer tech just a good diesel tech. Back to the oil priming the Case I have has a switch you can hold until the engine builds oil pressure then release it to fire. I only use it if it's been sitting awhile or really cold outside.
I really hope you get this mess lined out and the dozer operating again. Goodluck
my backhoe is like that sorta, it shows the gauge move at startup 5 to 10psi and then gets to 55+ after about 2o or so seconds, but at startup the needle does move to show something..but again it has done that for years, so I know its normal for that machine, but on a fresh rebuild and not knowing is more than scary..Hobbytime I've got a Kubota tractor that takes about 5-10 seconds to show oil pressure and when it's freezing temps seems like 20 seconds. Scares the heck out of me everytime. It's my second one and they have both done this. Worse is the skid steer, no gauge just hope the light goes out.
Another good idea! If you don't want to make a mess just set a tin of some kind under the filter head. If no oil coming some thing real basic is wrong! Did someone put a plug in the suction port of the pump and it never got taken out, don't laugh things like that have happened!Boy it's painful reading, the 3306 will pick up oil in seconds from new,a simple thing to do to determine where you go with this is, remove the oil filter and crank the engine over with the throttle in the stop position, if there is NO oil pumping out within 10 rotations something is missing, probably the oil pump?

Checked the gauge yesterday, works with air pressure real good!
