Good morning ,
I have a very old Case 680 ck ( b ) tractor backhoe which these days is rare but until now has always been in good working order .
The cast machined surfaces of the engine block where the wet liner O rings seal too ....has failed . Flaking away in short , I found some RTV sealant was present around liner O rings from the last fellow that had it apart no doubt .
The repair :
Just two options I've found at this point
1. Machine out the uglies , fit a bushing with red lock-tite & machine again to size .
2. Machine out the uglies , apply belzona 1511 ( ht ) & machine to size .
Regardless the repair method my plans are to coat the inside of block with belzona 1391 ( ht ) for long term piece of mind .
Could you please provide your opinions /options to this problem
Best regards
