I was that new guy 25 years ago, and glad I was... I grabbed ahold and didnt let go... Love the Mack's and allway's will..... Jojo

It's a private shop.. owed by a successful paving company in my area.. heading there tomorrow to stab a 12 speed into a Superliner... oh hell.. My back will be F'd up when i'm done... jojo
-
check the filter in the overboard breather for clogging and milk.. you are on a tough journey, because truc prices are out of sight, and now they are pulling out old 'junk' to sell for good junk prices... sorry bud.... jojo

Is air pressure present at the 1/4" line going in to the celenoid for the fan ? -
Here's me and my youngest one, (Tino)....last summer... jojo
-
be sure to dissconnect the home made wire at the sensor, leaving the truck wires attached.. good luck jojo
-
both.. when you cut the key off, in a few seconds the fan should lock, if its plumbed right. air pressure locks it.. hooking shop air keeps you from running it up to temp to see if the celenoid works.. Im sorry about being confusing.. jojo
-
Well its going to go to work when its done.. It will be painted the same way and built the same way as the tri-axle Superliner I posted.. This little truck wil have a Mack 12 speed.. it's been rebuilt and I'm putting it in on Wednesday.. It will be a hell of a truck... jojo
-
Thanks Bud... I forget things that I havent dealt with in years, and as far as the air leakoff.. I just learned it, and I will be checking for it when the truck is running.. Jojo

MR 688 electrical trouble shooting. No crank
Joey Mack replied to Ryanp's topic in Electrical, Electronics and Lighting
I chased an issue for weeks on an 05' Mack... It started up but #5 was not doing good.. the owner told me to put all new EUP's and injectors and fuel lines.. Still ran bad and smoked us out.. Well after a bunch of cussing, I decided to pull the heads to have a look.. and here is what I found... of course I started on the exhaust side first.. jojo

Have you looked through the 'Fire Apparatus' section here at BMT ? jojo
-
Ahhhh I remember that post.. Thank you for the compliment.. I have a Love for the Mack's... and I really enjoy chatting with my friends from around the world... Jojo
-

Vlad, isnt the name on the side of the truck i posted, what you are saying about Mack Built firetrucks... It's a 505-A... A 505 pumper on an 'A' model chassis? (1952) jojo
-
I dont have a lot of knowledge on them. I was just lucky enough to be asked to drive this one, so I read a little bit about it.. It still has the data plate on it, but I dont have a picture... However..... GADave has a picture of the data plate.. jojo
-
looks like the exh. is at the top.. try swapping the exh fitting with the fitting in the side port. then test it, you can put shop air to the truck, and cycle the key to get air to flow.. jojo
-
Ok, guys... Forgive me, I understand that a small air leak at the reversing relay is normal, but I'm not clear about when it gets it's pressure. I believe it gets air when the brakes are released... (Yellow Button in)? jojo
-
Welcome to the crew... Jojo
-
Here are some pics of a 1952 'A' Model that I drove to a firetruck show last year.. jojo
-
Heres the last one I was working on.. You cant see my work, because it was , Engine, clutch and tranny, all suspension, and I wired the truck from the buss bars under the hood, to the tail lights. I did tune the engine and fix the engine brake, (E-9) 500... This was last May.. 2 months ago he blew the engine. its now in Pennsylvania, at a shop with an E-9 Guy.. jojo
-
Im waiting for him to tell me to rebuild it.... It runs great, I supported re-sealing every thing, the color will be red and black when its done.. He has a crew of talented guys that do these resto's for him. I'm proud to be part of it. I dont know how to paint, and my fab skills are ok, but the guy in the picture is one hell of a welder and fab guy. jojo
-
Of course after I did all this..... the owner says... pull the injection pump and nozzles and get them rebuilt... 🤣😂🤑
-
Heres my 'current' part in this project.. I wont go back until the injection pump is done, and hopefully an exhaust manifold will show up by then. Then I can get this done... I wish we would have pulled the engine and put it on the rotator stand that they have..jojo
-
I guess so. I drove 4 hours to get this truck, then drove it back.. good runner, needed a bearing in the tranny, and an alignment, but is reallydrove good. For the life of me, I dont know why the owner had hid 'fab' guys cut it up to make a single 'x' with a tag axle, gonna be a dump truck..
-
the knurled knob is exh. it unscrews. in rare cases I have seen them plumbed wrong. i beleive, that when you switch the supply line with the exh. port, you change the way the switch operates. usually the exh. port is in the side port, and supply in the top, delivery to the fan out the bottom. jojo
