I am running very short on extra money and know I should replace the pacbrake with a new one. I took off the exhaust brake to find out what the part number and why the thing wasn't working. I found out the butterfly I would call it was in a semi half moon and couldn't stop any exhaust. The ram still works.
My question is if I straighten out the butterfly with a press and heat with it into shape will it compromize the metal asnd be a good idea?
It is a full marmon unit out of a isc 8.3 and the replacement is a c40108 from pacbrake.
I know that buying a new one is the best option but I can't afford the $740 for the replacement.
What is your thoughts

The question is why did that happen. Why did it bend to a half moon position? Can you still get the butterfly out so you can straignten it? If it was me I would try and staighten it. What do you have to lose by trying. If that doesn't work then can you buy just a replacement butterfly?

Hi Rex
I talked to that guy last week. He had another one on ebay without the ram that went for $102.00 and it was a half marmon. Pacbrake told me that it wouldn't work. I need a full marmon.This auction that is on now is a half marmon also.
Thanks anyway for the reply.

The butterfly is off the shaft and will be taking it to work. The coach has 150000 miles and don't know if the previous owners used to keep the brake on or what. I had to replace all the brake this spring because the exhaust brake wasn't working. Thanks for the reply.
John
