my b 7100 has a factory 1630c loader on it. its not a quick disconect tho. all of the hydro lines are threded in and there are no couplers, or valve to close off the fluid going to it. i wana know if when i go to reinstall it if i can just thred couplers and fittings into the block and lines? will it be ok if there is no valve to shut the fluid off? or will i have problems?
