After much thought and looking into many options I have decided the best decision for me is to go with the 7050 motor. I feel confident that it was being represented correctly and should go right in with out any problems.
If any of you have any ideas on what I should do to this motor prior to install or after installing please share. Thanks again for all of your advise. I have learned so much. Brad

I also own a an 8070 but with only 3500 hrs. Given that it is a 4 x 4 it has value. If I did not want to deal with the rebuild then I would sell it as is and someone else will rebuild. Then I would proceed to take the money from the sale and the savings from the cost of repairs and buy something with the 8.3 Cummins already in it. A White workhorse comes to mind. Would not spend time and effort swapping a different motor in it. Another option would be to go to a 2wd for baler work which would be cheaper.

Much easier said than done. Around here a Non-running Allis is yard art... I would have a hard time selling it if it was running. I can't imagine selling a blown engine Allis on tractor house and getting much money for it.... If I can get it to run and work again for under 5k that is what I am going to have to do. Hope that makes sense.

Your gonna have less hp,and if you change pumps you will have to change front plate and front cover. You will also have to change manifold or turbo for the muffler and the hole in the hood, and if you keep the 7050 pump you will have to change throttle linkage and put a kill cable.

I understand I will have less HP. Sorry I am so ignorant but what do you mean by the front plate and the front cover? Hopefully I can figure the rest out.

I M Planning on keeping the Rosa Master pump as I like it better that the touchy Bosch pump if that is what you are talking about?

If you keep the rosa you'll won't need to change cover.

You can probably use a fuel on/off cable from a 7000 series...you'll have to fab a way to use yor existing throttle cable but it's not a deal breaker

another consideration is a takeout engine from a late N6 combine, swap necessary parts around to bolt it in the tractor.
Are you near Delta and have a neighbor with a airplane cabled down near his shop? |

Gleaner: the properly engineered and built combine.
If you need parts for your Gleaner, we are parting out A's through L2's, so we may be able to help. |

I'm no authority. MACK says you replace that pressure plate,not machine it. the flywheel is only thing that gets machinedand it needs done to specs. It's in the service manual.

Thank you so much SteveM. I ordered a new pressure plate! I am going to see if the local machine shop can resurface the flywheel. Would you happen to have the specs? I do not have a service manual.

Need input from Doc or Mack or anyone else who knows but it seems like they shortened the dimensions up a bit for higher hp tractors.
