Hello everyone! I have a D12 (SN 3252) That also has a front loader and a backhoe attachment. I have done a little bit of work to it and it runs well - gets around and can dig well. However, it does not like any incline, and has very little power for scooping or pushing dirt. Mostly, it doesn't like inclines at all. I have conditioned the gas tank (its gas by the way) with RedKote. I have replaced the plugs, wires, coil and bendix drive to get to this point. i am about to inspect the points and condenser (this is new territory for me) from a suggestion from a friend.
In my case, I understand that the backhoe is an attachment, and therefore maybe not spec'd by the AC guys to have a bunch of power when moving around with it on. My friend says that lack of power could be from the points not being set correctly or corroded etc. Am I expecting this to have more power than what it should? I suppose I kind of expect ample power for, at least some incline - currently it will die because its is bogged down too much. Secondly, has anyone ever removed the attachment? I wouldn't know where to start and kind of worry that maybe I wouldn't be able to put it back on if needed to. Any insight would be greatly appreciated! |

I would suspect the float in the carburetor as your incline/lack of power issue.

If you're gonna replace the points, replace them with a pertronix unit. Almost the same labor, and you only have to do it once...

I have seen soooooo many allis tractors and have bought just as many ACs that the timing isnt set correctly, some jack leg thought they knew what they were doing and moved the dist, your little 12 ought to have plenty of power to do what ever you want to with it even with the weight of the lbh,

I agree with Dustin, everyone of the 5 I have, the timing was off

A badly worn bearing on the distributor haft can cause a similar problem. If the clearance on the points is set when on the level and you go up or down a slope the clearance can change. It is easy to check by simply taking the cap off and see if the rotor can be moved back and forth. I also agree with a petronix electronic ignition.

Travo, make sure your ignition is right and make sure your carb float is right and it'll run with plenty of power. My little D12 is a mule and doesn't know what a hill is. Your's should do the same.
As far as the backhoe, first off if your not real sure what you are doing, make sure you don't get yourself mashed. You'll be between your tractor and the attachment and that's an efficient place to get hurt. By the numbers...... 1. Just study how it goes on. Figure out what needs to disconnect first, then second and so on. 2. Take lots of pictures with your cell phone. They are a very handy thing and a picture is worth a 1,000 cuss words. 3. Make sure you are on level ground with room to work around the attachment. 4. As you take something loose, take a picture. If you take something off, orient the part as it would go on the machine and take a picture. 5. Label parts and hoses and wires in some way explaining what they are and where they go. Take a picture. 6. Put parts in a safe place, under a work bench or hanging on a wall in order as they came off the attachment. Take a picture. 7. Is the attachment off the tractor and you know where all the parts go? No---look at your pictures. Yes---open a beer, take a break. |
