530 stuck

Papa Fox · Mar 27, 2023

530 sat for several years in enclosed shed. When I got to it, it was stuck. Filled crankcase with ATF and acetone for 2 months. Wouldn't budge. Took off head. Valves not stuck. Jacked up rear tire and tried to rock it . Nothing. Keep shooting PB Blaster on exposed pistons/rings. Am I missing something?? Would be very hard for me to get the block out at present. Any ideas? t hanks.

you had to fill the spark plug hole with oil, not the crankcase. now all you can do is get a round piece of hard wood that fits exactly into
the bore and a big post mall and take turns smacking the pistons. she will come loose.if that dont work you will need to remove the block
with the pistons. which i dont think is nessesary.

Disconnect connecting rod? If you disconnect and in this case remove one con rod does it move a bit?
When rocked then there is all your weight on one piston instead of 2. If it doesnt work on one side try the other.
If it doesnt work on either pull both off make sure crank moves first!

I removed rocker arm on a 60 then used a
old spark plug with welded on air fitting
to put 50 pound air pressure in
cylinder.air pressure will force
transmission fluid and acetone around
piston.done each cylinder.let it sit for
couple days. Worked for me
