carguydave Posted August 17, 2012 Share Posted August 17, 2012 I recently picked up an EFU. It is serial number EFU 1S2155. It is mostly complete from what I can tell, missing one seat bottom and the driver's side hood louver panel. The truck is showing around 29k miles. It does have a two speed rear and the arrow turn signals (I don't know what else would be considered optional). I am new to Mack trucks and have been unable to determine exactly what year the truck is. I have done a little work to the truck and have gotten some of the shift forks to move (there was a squirrel nest that filled the bellhousing completely and froze the shift rods in Neutral). I have the cylinders soaking, and have gotten some movement (about 15 degrees) of the crank, so I am thinking the valves are probably stuck. All of the intake ducting and the exhaust manifold are there, so I don't think the engine would have gotten water in it. We live in a very dry area, so there is no humidity problem. In any event, I just thought I would introduce the truck to you, and see if you could tell me the year. Just to let you know, I may consider selling the truck, as I have had my eye on a 34 Cadillac. Let me know what you think of if. I will try to get some pix of the truck soon. Currently it is just a cab and chassis. Please email me directly, as I don't always check the Big Mack Truck site.Regards from SW Colorado,Dave Hennemanjmhenneman@frontier.net Quote Link to comment https://www.bigmacktrucks.com/topic/26832-can-anyone-give-me-some-info-on-my-new-efu/ Share on other sites More sharing options...

Superdog Posted August 18, 2012 Share Posted August 18, 2012 looks like it's had a rear end change.Sheet metal looks good.There's a guy out your way name of Ed Pruss thats got a really nice hood,grille,and both side panels off a EGU,but it would be same as what you have.He bought it from me to hang on his wall,don't know if he'd part with it or not.

carguydave Posted August 18, 2012 Author Share Posted August 18, 2012 Thanks for the info, I may try to locate him if I decide to build the truck. I do have the upper half of the pass. side louver panel for a pattern, and have a friend with a louver press. What makes you think the rear end has been changed out?

What makes you think the rear end has been changed out?it has budd wheels,probably a ford rear end I'd guess.If the rear was original it would have the spokes wheels just like the steer axle,with the chrome Mack hub caps in the center.
