I'm seeking advice on the best way to remove stuck Reverse and Brake pedals and shafts from an iron hogshead. I bought a used 26-27 hogshead with a good tight (but free) clutch release shaft because my original 26-27 hogshead had enough wear on the clutch release shaft that you could see daylight around the shaft where it goes through the hogshead.
The new hogshead has a free Low pedal and shaft, but the other two won't budge with me putting all my weight on them and I'm 240 pounds. So far, I've tried generous soaking with Kroil and these are the first two things that I haven't been able to free up with Kroil. I am wondering if I'm going to have to apply heat; how much, and where? The Reverse and Brake pedal shafts look like new (with surface rust) as does the Low speed shaft, and I'd like to use them once they're freed up, so I don't want to ruin the threads on them. The original band springs and nuts are fine and I can remove them, but I can't get the dang Reverse and Brake shafts to budge. Any suggestions?
Turn the hogs head on it's side and spray PB Blaster on shafts.Let them soak and spray them every so often after about a week try tapping the pedal with a hammer to see if it moves. It will eventually move a little and you can slowly work them out.
I'm with Jack, that's how I removed a few tight shafts.
Jack, when you say turn hogshead on its side, I assume you mean, the right side with the pedals sticking up, correct?
1 Forget Kroil & PB Blaster.
Penetrating oil comparison
Machinist’s Workshop magazine actually tested penetrants for break out torque on rusted nuts. Significant results! They are below, as forwarded by an ex-student and professional machinist, Bud Baker. Don’t forget the April 2007 “Machinist’s Workshop” magazine comparison test.
They arranged a subjective test of all the popular penetrants with the control being the torque required to remove the nut from a “scientifically rusted” environment.
Penetrating oil ….. Average load...Cost per ounce
None ................. 516 pounds
WD-40 .............. 238 pounds ... 25¢
PB Blaster ......... 214 pounds ... 35¢
Liquid Wrench ... 127 pounds ... 21¢
Kano Kroil ........ 106 pounds ... 75¢
ATF-Acetone mix.. 53 pounds ... 10¢
The ATF-Acetone mix was a “home brew” mix of 50 – 50 automatic transmission fluid and acetone. Note the “home brew” was better than any commercial product in this one particular test. Note also that “Liquid Wrench” is about as good as “Kroil” for about 20% of the price. Your experience may vary, etc., etc.
2 I'd soak it both ways, on its side with the pedals up and on its other side with the pedals down.
Hey Terry have you removed the bolts holding the cams in place? That'll help loosen things up.
don't forget when everything else fails fire and water will take anything lose. use care with cast iron. charley
I have used the ATF Acetone mentioned here in the forum with excellent results
Be sure to remove hogshead from car first. Oh. Guess you have.
