backhoe 310 lock up

[billva]

I have a 310 backhoe it set for 3 mounthsI think some rain may have gotten in through the muffler it the manufold it had a crack in it. I was tolled to pull the injectors and pour brake fluid in the cylinders then start working the crank shaft until it loosens. Is there anything else I can do to loosen it or could it be some thing else?

Don't pour in brake fluid; pour in automatic transmission fluid into each cylinder through the injector holes. Let it sit with the trans fluid in the cylinders for a few days soaking to do its job. Also be sure the injectors are still out when you try to turn it over with the starter motor. This should free it up. Do not try to start the motor after it frees up until you have spun it over to pump out the transmission fluid from the cylinders. GaJim
