Same Blakeslee F-20…. New problem
Hey Gang
@fixbear thank you for all the help with the oil. I finally found a good full synth #50 EP. I flushed and re-changed the oil. The machine runs like new!
I have the unit largely broken down ready for blasting and refinishing. I’m down to the last four bolts that I need to remove. Here’s the problem.
The housing including the bowl lifter and strap locks are aluminum. The slot head bolts are steel. I’ve used penetrating oil and impact drivers. These bolts wont budge.
I was thinking to use a drag link socket on a breaker bar but I’m afraid I might just shear the head off.
I’m also being told I can heat it but I’m not sure weather to heat the nut or the aluminum housing.
I also have no idea how much heat to add. I don’t want to damage the housing. Replacement parts are not available.
I’m thinking since this are steel bolts in an aluminum housing this is a case of galvanic corrosion but I can’t find anything out there on how to free it up.
I’m hoping someone might have some clever suggestion as to how to free up these bolts without destroying anything?
Thanks guys
