1965 Allis Chalmers FDX40-24 (5 months of service)

Hey guys and gals,

Thought I'd post my 5 month update on Allis after I brought her back from the dead. I've now passed the 30 hr mark of service and she is running excellent. Starts great and runs clean after around 2-3 minutes on a cold start. I've mainly being using her around the shop moving heavy item and the odd unload of some cargo etc around the complex. I've been doing used oil analysis on the engine to keep tabs on cleanliness of the Buda and am pleased by the results. Slowly cleaning up decades of dirt that accumulated from lack of oil changes. She's running like a dream and a real testament to the quality of Allis Chalmers. Here's some photo's

Getting ready for winter, Eh?

Sure am,:) Adding a heat exchanger to the exhaust on my 1940 Duo-therm heater. Running it on 50/50 waste oil and diesel.:) Keeps the shop nice and toasty when the snow flies.

Thanks Chris:)

Thanks Eric, They sure are an excellant machine and the perfect size for my shop. It makes lifting my Detroit and transmission a breeze. The Detoit project is coming along well. I finished making the flywheel housing adapter and fits like a glove. I just started working on the cranshaft adapter yesterday. Just doing some final trueing up on my lathe before I start turning out anything. Excited to get the cranck adapter finished so I can start fitting the engine in the frame and making mounts for it.

Them welds on your stand were a little cold on the amps - got beads that are standing up and not a lot of penetration - next time use 6011 rod and about 100A

Cal the proper way to operate a Detroit is to either slam your hand in the door......... or to smack a thumb with at least a 20 oz. hammer,(keep in mind a glancing blow seems to work better).............

Also if you can pin the governor to nearly max after a sufficient warming time, it seems to run more efficiently,,,,,,,,,,,,,,, remember it is a supercharged motor,,,,,, and when the rpms drop, so does boost! Drive 'em like you just stole 'em..............

You don't really have to be smart if you know who is!

Lol, every video I see on a Detroit I always asked them if they slammed their door on their hand first.:) Some get it and some do not:). Here's a gal that clearly gets it. http://www.youtube.com/watch?v=Tas59JfTrt4

we have 2 detroits on the farm now and they give absolutely no trouble. neighbors love them have several trucks, tractors and even a Gleaner G with one. I can hear him anytime he moves the trucks as they are straight piped, and usually know they are coming 3-4 miles away

alt="LOL" title="LOL" />

Our neighbor has an Oliver 1950 with a Jimmy in it with straight pipe. You can hear him from a mile away. Great sound.

My Dad was a milkman and had 6 route trucks and 2 tractor trailers. I ride with him for years on the semi trailer route. He had a cab over cracker box GMC. It was a real screamer. We would drive with the windows down all year to hear the dual straight pipes sing.

Always told that they were hot in summer and cold in winter, no insulation in them, used to drive a 238 in a International cab over that's the way it was drove shame door on hand and then hang on

local excavator company here had them GMC's diesels, they straight piped them and they sounded awesum...well to some anyways. the locals city fathers sent them a letter banning them from driving thru town with them. so now they can't have the fun they used to have! PffffT!

The real truth is you had a Crackerbox with a 238 or a 318 in it and you walked up, open the drivers door, place hand in opening then slam the door THREE TIMES to assure you were angry enough to slam that shifter and mash that throttle!!

Was told that in 1975 by an old geezer as I am now, training me to drive old Freightliners with 8V71 318 Detroit engines.
There is a song to the old two strokers exhaust that many will not ever understand.

Pierson Truck Sales in New Florence MO has a running skid mounted 12V71, have a second unit sitting in the floor next to it, would LOVE to see that in a old 9500 on a thirteen or two stick trans and listen to that song PERSONALLY from the driver seat!!

that's a mighty fine looking "saved" machine you have! i'm sure you'll get lots more years of service from it! what kind of shop do you have?

Thanks, I'll keep the old Allis for at least 30 years if I live that long:) The shop is a 1200 sqft space I have for personal use for maintaining my vehicles and doing restoration and such. I have a two post lift, lathe, welders, and the tools both my own and the ones I inherited from my dad when he past. I guess in a nutshell it's a mechanics, metal, machine, and restoration shop.:)
