Cummins 160 parked for 10 years. Will it run?

Pressurising a container with air is the same as pumping more fluid in. It will only hold so much. Overflow not venturi.

Pressurising the tank will work fine to get the fuel out the normal pipe but your system "vacuums" all the rubbish off the bottom - much better.

Relating to PDU's post the fellow who did the body work on my 1938 Holden bodied car requested the same gauge material for replacing rusted areas as the car had. This was 16 gauge or 1.6 mil, found it too difficult to fold and used 1 mil zincanneal.

Lang, very informative, I used to play the clarinet…. Not very well…. I will let Scout have first go when he gets back….

You might've noticed it's been a while since I asked the question in the topic. The short answer to my question "Cummins 160 parked for 10 years. Will it run?" is no!  Long answer is the engine appears to be seized and I'm not sure why. In the 12 years since it was last started the truck has been parked in a dry shed. There is no evidence of rusting on tools or bare metal also stored in the shed, so while some cylinders may have been sitting with exhaust valve or inlet valves fully open, I can't imagine that there has been enough rusting in the cylinders to completely immobilise the engine. I've also speculated that coolant leakage through the head gasket may have caused hydraulic lock, but I can see no sign of loss of coolant or nor signs of coolant in the oil. However no amount of levering on the engine will get any movement out of it. I even tried jacking the rear wheels off the ground and with the gearbox in top gear and using 20 ton jack on a strong steel bar attached to the wheel hub, all I was able to achieve was putting bend in a good piece of heavy steel. 

Next step will be to pull the injectors, which isn't going to be easy as the injectors are mounted inside the rocker cover and are actuated by rockers connected to a cam shaft, so the rockers and a web or fuel pipe needs to be disconnected to get the injectors out. So before I take that step I'm hoping someone can point out any rocky errors I may have made.

 

The middle rocker in the group of three for each cylinder actuates the injector.

First Id look for a stuck injectore...Ive not seen a stuck Cummins injector ,but its possible ......problem is Cummins injectors are seated for a lot of the cam rotation ,,but ant fuel rocker thats up should be able to be moved down. .......... I hope a mouse hasnt found an open valve and built a nest in a cylinder ...........some guys I know started a pair of Cummins V1710s with water in the cylinders by simply crashing away with starter on 24v (or maybe more) .......they wrecked some starters but got both engines going (in Hough 500 loaders)

Thanks John, I will check the injectors. I haven't had any signs of rodents in my shed, so I don't think it's a mouse I'm trying to squash with the piston. I did briefly try hooking the starter up to 24v, but got nothing more than hot battery terminals.

You could probably take the rocker stand off and replace it without setting the injectors ......the injectore plungers are a free fit ,and Id think the spring could be pushed down easily by hand ...anyway ,it should be easy to see if any are stuck........Did you check the clutch plate rotates free when the back wheel was off the ground ...eliminate any gearbox problem?....I had an Inter that the gearbox would go into two gears at once and lock up the box.

I agree with John.  Start by looking for a stuck injector.

If you need to pull the injectors, just be aware that the injector push rods are a different length to the valve ones, so don't inadvertently mix them up. As a young bloke starting out and doing my first ever Cummins, I made that mistake and bent a few.

Thanks JohnK, 180Wannabe, and Wee Allis, I had been wondering about the injectors, It will be an easier fix than a stuck piston. And John, the gear box was the first thing I checked as it was the reason the truck had been sitting for so long, while I worked out how tomato to fit. So when I had the wheels off the ground I made sure everything was spinning freely and the clutch was disengaging properly too, but good advice.
