Massey 240 engine locked

[2YardOfLard]

Hi folks,

thanks for the help with the starter motor, it came back from Rotating Electrics Yarmouth fixed and has been fitted.

When the key was turned, it turned the engine a very short way and then the engine stopped turning, feels like a dead stop and the starter won't turn it further. Its been sitting outside since last summer in Scottish weather and i'm thinking its partly siezed or hydrolocked with water ingress via the exhaust pipe.

I can tow it to break the siezure but if its water in the bores, it needs getting rid off to prevent hydrolock bending a rod. I thought I could take the rocker cover off and screw in the tappet adjusters so the valves are slightly off their seats so the water has a path when the tractor is towed.

Any thoughts or ideas on that

Just take the injectors out and try it again on the starter.

^^^^^^^^^^^^
This every time.

Failing that take the head off, to see what's going on inside.

Thanks for the quick replies, anyone know if the injectors can be accessed without taking the bonnet off?

They can on a 290, so I would assume so for a 240.

Thanks for the replies, all....I think I'll be ok now

Think the fuel tank is on top of engine on them, bonnet off and tank off

I think you will at least be able to slacken them maybe even remove them. The hold down nuts the rear of the injectors should be tall nuts which makes it easier. Bonnet is easy to remove in a 240 and just slacken tank bolts and tilt if you need to.

Thanks mf Andy much appreciated....it's three degrees and windy here so will wait a few days

I’d start by removing the starter to get a bar on the flywheel to try and rotate engine before fiddling with injectors

Take air filter off, put in 1st gear and pull backward?

Why

 

[Rick1971]

It can reverse the engine so water pushes back through inlet and up through filter. Stops hydraulic on many engines.

Don't be silly, there will be a compression stroke which ever way the engine is turned.
So your idea is a total no go and won't work

 

[Rick1971]

Yes but the Ex valves will open near TDC one way. I did a few cars this way when flooding was bad and no garage had time to take heads off. Takes a bit of thinking about but does work as quick fix and back on road.

Slacken the injectors and don't risk bending something by trying to break it free. Its not a big job.

 

[smcapstick]

As above, slacken / remove injectors.

Do not drag it around the yard backwards, forwards or any other way in gear. That’s a f**king stupid idea.

It might be a dropped engine valve, if you take off the rocker cover that should show, best check that before starting if the other suggestions don't fix it.
