hello all.. recently purchased this elderly ford dump. it apparently has a 391FT engine, but I have had no success in researching the VIN. tags, plates and stickers regarding parts/components & ratings are missing or illegible. I do know the GVW is 44.500#. It has a 5 speed tranny - I am hoping it is a Clark as they seem to be highly regarded. it has an aux trans but I don't know much about what that might be.. the shift knob does have an 'OD' on it but the rest of the knob is worn. Is this likely to be a 'brownie box'? I have read some about those lately. My question here is can anyone tell me how to determine what the major components are based on the VIN? (T81FVR23445) INFO I do have is as follows: 1974 Ford 10 wheel dump, model T812F, GVW 44,500# (I am assuming 34k rears/10,500 front) Thank you folks in advance.
got pictures????got part numbers off the ID tags...start a photobucket page.. its free.. upload your images there...paste the links to the images here..then we can see what you are talking about..i would probably bet its an UNDERDRIVE set up .. not an overdrive set up in a dump truck.. so they could slowly power up out of deep diggings.. but it could be anything..i don't know if this will have the answer you need...http://www.faxonautoliterature.com/1974-Ford-Truck-Service-Specs-Manual-P24270.aspxperhaps you will just need either the service manual.. or a cd copy of it..http://www.faxonautoliterature.com/Search.aspx?c=179457usually factory manuals have the possible build components listed in a section...you will still have to figure out a way to identify which parts are yours.. but this will help... i missed your answer.. does this truck have air brakes.. or vacuum hydraulic assist
