I purchased a new master cylinder from Jim Carter parts for my 1953 6400 2 ton truck. The original master cylinder I removed had a double flare 1/4' fitting in the end cap that was part of the large nut end cap of the MC. This was not a a fitting added to the large nut cap but rather part of the cap. The new one I received from Jim Carter is the correct MC but has a deep 5/16" threaded end with a flare similiar to a pipe thread, put it was not a pipe thread. Before I sent this back I tried to find a 5/16 to 1/4 adapter at several local auto parts stores. None to be found. I called Jim Carter's and from what I was told, Jim Carter looked up the MC for my truck & confirmed it was correct. I did not speak directly to Mr. Carter, I am not sure the girl who I spoke with relayed the info correctly. However she was told that I could send it back if I wanted to or I could swap the end caps if they would swap. I decided to swap end caps. Currently they appear the same except the thread size & flare for the hydraulic line. I have not swapped them yet due to having to sandblast the old one & paint it. It's now drying. I felt that if I sent it back and had them send me a new one I would be in the same situation, or did the new MC get the wrong cap installed at the manufacturer. I am pretty sure this MC gets used of more equipment than the 1953 Chevy trucks.
Sorry to make a long story out of this. Has anyone else had this issue with the hyd line size being different when purchasing a new MC. If so what was your solution?
I realize if we are doing these restorations on these old trucks we need to be resourceful. However I don't expect to pay good money for a part that is supposed to fit my truck & have to modify it to able to install it. Am I missing something here? Nothing against Jim Carter's I am thankful there is a company out there that handles parts for these old trucks & I will continue to use them for my parts.
