Ton Posted February 10, 2020 Share Posted February 10, 2020 I have a ac mack and I was wondering if anybody could tell me about the high low lever that goes to the transmission. Thanks Quote Link to comment Share on other sites More sharing options...
ekennedy21 Posted February 10, 2020 Share Posted February 10, 2020 There isn’t one. Pto maybe? Quote Link to comment Share on other sites More sharing options...
Ton Posted February 10, 2020 Share Posted February 10, 2020 it has a pto on top. this goes into the tranny. Quote Link to comment Share on other sites More sharing options...
steelman Posted February 11, 2020 Share Posted February 11, 2020 On all of the AC's I have seen or ever fooled with, the pto is on the drivers side of the tranny, and it is controlled with a shaft that puts it in or out of gear. The only other shaft to the tranny is the gear shift lever which rotates and moves forward and back to select the gear you want. Quote Link to comment Share on other sites More sharing options...
Ton Posted February 11, 2020 Share Posted February 11, 2020 It must have a different tranny in it then. It has the gear shift shaft going into the front of the tranny. And to the left of it and down a few inches is the shaft that goes in and out that's hooked to a lever that goes forward and back. Its next to the shift lever. The pto is on top. Thanks for your input. Quote Link to comment Share on other sites More sharing options...
Ton Posted February 11, 2020 Share Posted February 11, 2020 I'm not sure of the year of the truck. I sent the serial number to mack and just waiting for info. Quote Link to comment Share on other sites More sharing options...
Ton Posted February 11, 2020 Share Posted February 11, 2020 Stamped on the transmission is. CTCX 202-88. What would be a good oil for the transmission and rear of that Ac. Thanks Quote Link to comment Share on other sites More sharing options...
steelman Posted February 12, 2020 Share Posted February 12, 2020 Any heavy weight transmission oil, like 90 wt. would work in the transmission. There is no rear end that takes oil. The bearings in the wheels take wheel bearing grease. What do you have? Any pictures?? Quote Link to comment Share on other sites More sharing options...
Ton Posted February 13, 2020 Share Posted February 13, 2020 Thanks it's a ac mack I think it's early to mid 30s I will get a pix of the tranny. Like I said before it has a pto on top and two shafts going in the front one goes to the shifter and the other goes to a lever next to the shifter that might be high and low Quote Link to comment Share on other sites More sharing options...
Ton Posted February 13, 2020 Share Posted February 13, 2020 I think it is a 7 and half ton ac. 17 leaf springs in the rear Quote Link to comment Share on other sites More sharing options...

steelman Posted February 14, 2020 Share Posted February 14, 2020 The serial number should be stamped on the frame on the left (drivers) side, facing up (on the top flange of the frame). What is that number? We can tell you when built (approximately), and what size/capacity it is. It should be a number, like 10ACXXXX, or similar.

Ton Posted February 14, 2020 Share Posted February 14, 2020 The number is. 4AC1CM1634. Quote Link to comment Share on other sites More sharing options...
ekennedy21 Posted February 14, 2020 Share Posted February 14, 2020 medium duty 6-9 ton built between feb. 1932 and aug. 1934. I would guess a late 32 or early 33. Quote Link to comment Share on other sites More sharing options...
ekennedy21 Posted February 14, 2020 Share Posted February 14, 2020 Also, on those later serial numbers the 4AC signifies that it is a 4 cylinder and 6AC signifies a 6 cylinder 1 Quote Link to comment Share on other sites More sharing options...
Ton Posted February 14, 2020 Share Posted February 14, 2020 Thanks so much for your help. That's a great start . I have the motor turning over now with spark. Any thoughts on the transmission in the picture that is in it? Quote Link to comment Share on other sites More sharing options...
ekennedy21 Posted February 14, 2020 Share Posted February 14, 2020 No, but I am going down to NJ to see Gary Mahan in about a week. I will ask him, and he will certainly know. Quote Link to comment Share on other sites More sharing options...

ekennedy21 Posted February 15, 2020 Share Posted February 15, 2020 those engines run real good with a Stromberg SF-3 set up properly. I switch from a zenith and it made a huge difference. Quote Link to comment Share on other sites More sharing options...

Here is a few pics for about 1929 to 1932 or so. I had to photograph them because I can't flatten the book enough to scan it. The hole one the lower left is where the up / down control rod passes through to the screw feed on the dump unit. So your unit had a MACK built heavy dump body from the factory. You can see it clear in one photo. One of my AC 6 units has the same set up.
