Hey All,
Thursday, September 6,2018, Morning Update:
While awaiting the arrival of the 1959-1968 Dodge Post Office Vehicles Parts List Supplement, due here Monday, September 10, 2018, (if not sooner, because it arrived in Dallas, Texas at 5:32 a.m. on Wednesday, September 5, 2016), and which supposedly has an "interchange parts list", which is assumed to have be a list of "alternate parts" which the Post Office Maintenance people used to keep the Post Office Vehicles percolating, have been doing some "outside the box" thinking on ways to keep Lorrie Van Haul doing the same.
As you may or may not know, or as you may or may not remember, last week saw the arrival of the 1967-1968 Dodge Truck Factory Shop Manual.
Have been pouring over its contents and grokking everything possible about the Dodge Steering System used in Lorrie Van Haul, among OTHER similar vehicles.
Am going to here do a summary of the subject, because there may be some nuances which have been overlooked, and the experienced people here at SSF just might be able to see something that I'm not seeing.
So here here goes:
Lorrie Van Haul is a 1967 Dodge P200 Post Office Vehicle, with a Right Hand Drive Gemmer Y4D-335 Steering Gear Box. [Note: This may or may not be true, as it is unknown whether the Post Office Maintenance People have MAYBE swapped out Lorrie's ORIGINAL Steering Gear Box, or whether the present Unit IS Lorrie's ORIGINAL Steering Gear Box]. In any case, we are going to proceed with the assumption that the Unit presently installed in Lorrie IS the ORIGINAL Unit, and if it IS, it is listed in the 1967-1968 Dodge Truck Factory Shop Manual, as the aforementioned Gemmer Y4D-335 Steering Gear Box.
In addition to the Dodge P200. there is also listed in the 1967-1968 Dodge Truck Factory Shop Manual, as having a Gemmer Y4D-335 Steering Gear Box. OTHER Vehicles that have the Gemmer Y4D-335 Steering Gear Box. That list of Vehicles includes: The 1964 Dodge P300, P400, D400, S400, D500, D600, D700, S500. PD 500, and PD600.
In addition to the above listed vehicles that have a Gemmer Y4D-335 Steering Gear Box, there is a list of Vehicles that have a Gemmer Y5D-375 Steering Gear Box. That list of Vehicles includes: The 1964 Dodge D500, D600, D700, D800, S500, S600, PD500, and PD600.
The question arises: What is the difference in all these Vehicles?
The answer to that is only "implied" in the 1967-1968 Dodge Truck Factory Shop Manual, as the information included lists the P200 as having a Front Axle Capacity (FAC) of 2,800 (am assuming that is "lbs"), the P300 has a FAC of 3,800 lbs, the P400, D400, D500, D600, D700, S400, S500, PD500 and PD600 have FACs of from 4,000 to 5,000 lbs. And for the Gemmer Y5D-375 Steering Gear Box. all the Vehicles listed as having THAT unit, having FACs of 5000 to 7000 lbs.
So the implication is that the higher the number, the greater the Front Axle Capacity, which implies that the HIGHER the model number, the BIGGER the Vehicle.
A bit of analysis is in order.
Notice that BOTH the Gemmer Y4D-335 Steering Gear Box, and the Gemmer Y5D-375 Steering Gear Box a used on D500 and the D600, which would by logical extension (maybe) mean that the Gemmer Y4D-335 Steering Gear Box, and the Gemmer Y5D-375 Steering Gear Box may have the same Mounting Bolt Pattern. AND by further logical extension (maybe) that would mean thatGemmer Y4D-335 Steering Gear Box, and the Gemmer Y5D-375 Steering Gear Box are interchangable!
So the next thing is to see (since so far there have been ABSOLUTELY no availability of either the Gemmer Y4D-335 Steering Gear Box, OR the Gemmer Y5D-375 Steering Gear Boxs, what AVAILABLE Steering Gear Box Units ARE being offered that will fit the: P300; P400; D400; D500; D600; D700; D800; S400; S500; S600; PD500; and PD600?
But even if all that information is possible, there is still the FACTOR, that the Steering Gear Box HAS to be a Right Hand Drive Unit. And THAT is what the 1959-1968 Dodge Post Office Vehicles Parts List Supplement will hopefully reveal.
Also, there is MORE!
There is also mentioned in the 1967-1968 Dodge Truck Factory Shop Manual a Saginaw 525D Steering Gear Box for use in the D100, D200, D300, W100, and W200.
There is also mention of a Gemmer B-60 for use in the WM300.
There is also mention of a Gemmer 6D-400 Slim Line, for use in the W500, D700 and D800 (notice that these last two models are also listed as being able to use the Gemmer Y4D-335 Steering Gear Box).
Further, in doing all this research, have found historical information about Gemmer, Ross, Saginaw, Packard, Dodge, Power Steering, and gobs of other stuff, about which we will write later.
But this is it for now.
Will keep you all updated if, when, and as progress occurs.
Take care everyone.
JC
