Mack-a-tron Posted 4 hours ago Share Posted 4 hours ago Good afternoon all, I'm looking for a rebuild kit for my DLNR valve located on the top of the main transmission stick in my 1979 Mack RWS786LST. It currently leaks a substantial amount and needs repaired. Mack wants gold standard and my first born for a replacement and I prefer to rebuild what I have. Can anyone help me find the repair kit for this? Also, it seems difficult finding parts for this truck and honestly it's irritating hearing the response that the truck is "really old." Do you all get this when you are tracking down parts on your antique truck? I feel like when I call RDO its like I coming to them with an STD, I don't see why its a problem keeping these older trucks operating. They have unique style and character you don't see in today's models.

tjc transport Posted 3 hours ago Share Posted 3 hours ago any time i had leaks on the range splitter they were fixed by replacing the o-rings in the head. no need to replace the whole thing when a few o-rings should fix it.
