Engine Seized Up

While trying to start my 226 inline 6 motor after a fifteen year rest, the engine seized up. The engine would turn freely by hand and would crank with the starter. While I was trying to get the engine to fire, she seized. Could something have happeded to starter, causing the engine to freeze?

First off, Check to see if you can turn the engine over by hand. Put a wrench on the front crankshaft pulley. It you can turn it, it's not seized. If you can't, you may a starter that's locked up, or burnt up.
How long a period are you cranking the engine at a time?? Could be you heated up the starter. I presume this truck is a 6 volt system. Are you jumping it with 12 volts?? If so you have fryed the starter.
Hope this helps.

Before you start replacing things, try loosening the bolts that mount the starter to the engine, give it a whack with a rubber mallet, then re-tighten them. It could be that the starter gear has jammed in the ring gear. This is fairly common in the old tractors I work with, and the 6V truck starters are very similar to the tractor starters.

I can no longer turn the engine by hand. The system is the original 6v hooked up to a 6v battery. I was cranking the engine in short intervals trying to get gas to the carb. Although, the starter was making clicking noises, then nothing. I give the "whack the starter with a rubber mallot" technique a try.

Thanks for the help.

Did you remove the sparkplugs and put any lubricant in the cylinders prior to cranking. I'm sure you don't feel like a lecture now but 15 years is a long time for a motor to sit. At a minimum, a little surface rust generally forms on the cylinder walls. I usually give them a good dose of penetrating oil like Liquid wrench or whatever. Turn over by hand the next day and follow up with motor oil. Then crank and hope. Turning it over dry can be extremely destructive to rings, pistons, cylinder walls. Not to late to lube and try again. Nothing to lose.

Good Luck

IF the starter still clicks load that gear isnt stuck out to gear.
If nothing happens,then you could be lucky and the starter is stuck.After the years the copper guts corrod and wasps get in them.

A stuck engine ussualy is from corroded pistons,they are swelled and rings will not move sid to side or in/out therefore binding the piston.If it has a timing chain,it could rusted and locked up in a few turns.
