Double post, but thought this a better forum to get some options/fixes.
Below is a picture of the mounting bolt for the coolant pump idler pulley on a CAT 3126. Bolt is directly into the block, and in a pretty tight location. Maybe 1/2 a thread above the surrounding metal.
What’s the best way to remove? CAT hardware is typically high strength, hardened bolts and usually take a fair amount of torque to back out. Looks like it’s been in there a while or possibly a former owner/mechanic sheared it off. I don’t think a HD or Lowe’s easy out will get this done.
I’m thinking drilling and running a cutting tap down to remove the remnants, but getting it centered up is going to be tough. Access is not easy.
Maybe try welding a nut on? Not a whole lot of material. Id have to buy a welder. Obviously a little “fire and ice” treatment will always help .
Maybe call in a mobile machinist?
