Yes its a fuller. Do u mean remove and replace slave valve??

Would like to keep it all original.been trying to find a free manual online, am unsuccessful. I think I find one, then it leads Me to a dead end. Also been working on my two speed. Once I flip up, doesn't always flip back down. I have to flip it back up and then it will go down....blew out all the lines. Has new regulator. ??

Am having trouble with wiring up my alternator in my,1982 Mack rw Superliner. Its a dump truck for which I have no manual. Anyone have any advice? Am raising this old truck from the dead. Any help appreciated.
