My 673 E has Mack 88GB439P672 43-7712 my extra engine 675 has Napa 13A1675 on both these engines the generator sets close to the block right under the intake manifold .

I pulled the pan today not sure what I would find it was very clean .I pulled a main and a rod cap bearings where dated 8-98 both looked good a little wear . I bought a military bell housing that will let me use the mounts already in the truck .This bell housing hold the rear seal the original seal retainer on the engine is not used .I looked for piston oilers and this engine has none . I don't know what horse power or torque this engine will have ?

Thank you That good to know I have not taken the pan off of this engine but when I do I will look for spray tubes .

Thank you I looked it up .they do have a few engines listed .I need to look at the ones I have before I buy another . The other engine is a 675 I have not looked at real close I bought It because it it has a sae #2 bell housing and a belt driven power steering pump . all in put is good information for me .

I bought two mack engines one of them I will rebuild and put in my 1967 kaiser Jeep 5 ton military truck . There is a engine on Ebay that is a 673 E it is with out a turbo. the engine I bought has a turbo . Did the 673E come both way or the turbo added ? any information on the 673 E would be helpful .

I think it's good to work the engines in these older trucks to heat them up and get every thing warm it's just not the same driving them empty .

I heard years ago that your dog will always love you more then your wife .This is tested by locking them both in the trunk of a car and letting them out 24 later and just see who is happy to see you . and then the fight started .

I do about the same . I asked mechanics about adding another stack and a valve to exhaust to let the exhaust go through the factory stack on the highway and through the plane muffler on the dirt . they thought it may be illegal and not sure if it would even run ?

The Cruiseliner in the first part of Convoy dose not have one on the grill but it looks like the same pattern sewn in the seat cover .

Do you drive it on a lot of dirt roads ?

1967 M52a2

Hello I found this site when looking for Mack parts for a engine swap on my 1967 Kaiser Jeep M52A2 5 ton tractor . it has a multifuel LDS-465 A1 engine in it now on the way to the ATHS show it cracked a piston I don't want to put money in this engine . The military had Mack engines in some of these trucks so that what will be going back in . I have worked in the oil and gas fields around Farmington NM since the 1970's I have driven lots of Macks . I like the Mack before Volvo the best when they made every thing when getting parts you only had to go one place and Macks always had the best drive lines . My first truck I rebuilt was a 1953 GMC m211 turned in to a tractor . I also rebuilt a 1954 military M269 wrecker lowboy and added ramps . I have a 1943 white 666 I want to rebuild but I have no time I should have started on it a few years a go and I just don't have the time it will have to be sold . lots of good information on this site and I should be on hear daily .

No I don't . I think I may have one off of a 45,000 winch that came off of a wrecker .I know its to big for 20,000 winch on a 5 ton

LDS A1 Multifuel out of a 5 ton .

No I don't know him.

My first post .I did get a bell housing to put a Mack ENDT engine in to my Kaiser Jeep M52a2 .
