39 Baby Mack

On a lighter note: I bet when Joe from Florida asked about the filter numbers for his "B" model he never expected this much information!!! Ron

I know what you mean Mike, We lost several V-8's this way. One of older drivers used to always keep the L.H. quarter fender on his tractor clean as a whistle, even if the rest of truck was dirty, you can better bet that quarter fender was clean. That was his early warning device for problems with the oil lines. Needless to say, out of the ones we lost because of this, he wasn't driving any of them! Ron

Matt The earliest truck we had with that filter was a 1963 "F" model with a V-8. As I stated before I think the development of the END864 V-8 had something to do with the introduction of the full flow/bypass filter. It was then engineered to be also used with the six cylinder engines. Ron

Matt All the ones you have are full flow/by pass W.G.B. filters, used only on Mack's. Ron

Welcome to the group! Ron

Matt The 750C isn't the one with the gaskets, it's made for a Luber-Finer housing, just a by/pass filter. Ron

Sorry to hear about your dad. Ron

Looks good! Ron

Matt The 750C is the element for a 750 Luber-Finer, it is a by/pass filter. The filter Joe has is the full flow/by pass filter specially designed for or by the Mack Co. and made by the W.G.B. Oil Clarifier Co. from Kingston, NY The only things the 2 filter elements have in common is there physical size. The element for the Mack filter has a gasket permanently installed on either end of it (nothing to do with the housing gasket). The one for a 750 Luber-Finer does not. The element in the W.G.B. filter is held down with a cast top containing check valves to control oil flow, it mates with gasket on the top of the element. The element in a 500 or 750 Luber -Finer is held in place with a Tee handle with a spring mechanism built into it. The only difference between a 500 and 750 Luber-Finer is it's size. All Luber-Finers have the two smaller lines. and were used on many different make trucks. The Mack designed filter has the 2 #16 Aeroquip lines for full flow, with the third smaller line for by/pass and you'll only find this filter on a Mack. Earlier Macks came with Luber-Finers, it was the only game in town. I think the full flow came out about the same time as the END864 V-8. The V-8 probably had something to do with the introduction of this filter. Good idea but if one of those #16 Aeroquip lines lets lose you don't have much time before your engine becomes a "Boat Anchor" Especially on an "F" model with the filter was mounted on the L.H. frame rail behind the battery box! The lines were much longer, even longer still if it had a 6 cylinder in it rather than a V-8. Ron

Don't forget to get a new gasket for the oil filter housing, I don't believe it comes with the filter. Baldwin # G-157 Ron

I'm with you, how fast was he going? Ron

Randy, There's a Tilted Kilt in King of Prussia right of the Schuykill Expressway. They even have valet parking, have had the "Big Blue Machine" there a couple of times. Always had to park it myself, imagine that!!! Ron

Joe that's a full flow/by pass filter. Mack #236GB311A Baldwin #P706M The big lines are #16 aeroquip The small line if memory serves me right is a #6 Ron

You should be able to bring the piston up to T.D.C. this will hold the valve from falling into the cylinder. You would have to fabricate some sort of spring compressor. The compressor can be leveraged off of a bracket bolted into one of the bolt holes in the head for the rocker arm pedestals. Ron

Yeah, you and me both, Mark! Wonder what he has tied up in it? I would imagine the transportation charges alone were a pretty penny! Definitely one lucky "Bulldog" to find a good home like that! Ron

A few more. Ron

Great news Ernie, Will keep you all in our prayers. Ron

Fuel filter would be a Mack #237GB13, Baldwin #PF819 Oil filter would depend on whether it's a by-pass filter or a full flow/by-pass filter. How many and what size lines are going from the pad on the side of the motor to the oil filter housing? As for oil I'd use 15W40. Ron

Thanks Katie, She already likes Macks, and has her fair share of stuffed Bulldogs! Ron

Welcome to the nut house! I have a daughter named Katie. Ron

Well put Mike! Ron

Happy Birthday!
