I have a complete 450B that was running but due to extreme corrosion in the block-sleeve interface the engine cannot be rebuilt and it will not hold coolant. I bought it used and it leaked badly
ever since I had the used motor installed. Consequence of putting plain water in as coolant instead
of antifreeze. So I either sell it as parts machine or try to get a running motor in it. The undercarriage is worn out as well and the last few years I used it, I only used the back hoe
and put water in it every 20 or 30 minutes. I had to tighten the tracks up every 50 - 75 yards
with a grease gun as the adjustment cylinders leaked grease badly.

Third option. Keep your crawler as a donor. Buy a good B series and you have a abundance of parts. This is what I did. Retired tired iron, keep them, but upgraded to better machine.
