I have searched the archives and I can't seem to find anything about the proper way to break in a motor. Maybe I am not looking under the right headings? Could someone tell me, when I should put it under load? How much weight at a time? Any other tips to breaking in a motor? Any advice would be appreciated! Thanks Bob

Let me ask if any of you do this,I put a magnet on the bottom of the oil pan as close to the drain plug as I can get it for the first few hours of operation to catch as much of the ring dust as I can.Any body else do this?

I don't know specifics, but my uncle Al bought the 140th H, after a barn fell on it and it hadn't been run in 15 years. He got it running, repainted it, and although he could have done something in the meantime, there was two weeks between coming out of his paint shop and running balls to the walls on a thresher at our annual show. Ran beautifully. I can't describe it. So, Bob, there can't be too much, because Alvin farms almost full time, too. Good luck, and enjoy the H.

Bob I vary the RPM for the first couple of hours with bascially no load on the engine. I then retorque the head nuts and reset the valve clearances. I also change the oil and filter to capture that initial ring dust you will get on a break in. Then I go for it. I don't think there was much information breaking them in when they were new.

I'm sure you will get various opinions on this. Should be some interesting replies.

I did retorque the head and reajust the valves. I also changed the oil and dropped the pan to clean any ring dust. I only have a couple hours on the engine. My local tractor show is next weekend and they have a tractor pull there. Do you think it would be too soon for me to try with my H? The tractor still smokes a little and burns a little oil but I'm hoping this is because the valves and rings are not fully seated yet. Thanks Bob

If you haven't had any problems so far, I personally would put it to hard work.

Thanks Red! It has ran perfect so far except for some smoke. seems to have plenty of power. Only problem I have had is when you bring the throttle up about 3/4 of the way and farther up the motor seems to surge, but runs fine anywhere below this. Got any ideas why it might do this? thanks again! Bob

If it is only surging in the high RPM range, I would replace the governor spring. If it is unsteady at various RPMS, I would suspect the thruster bearing assembly is worn and wobbling on the horizontal shaft.

Thanks Red! I figured it was probably something with the governor. I probably won't fool with it because this is mainly just a show tractor. i do have to fix my carb problem though. it is running way to rich especially at idle. I tried adjusting the screws on the carb but neither seems to make any difference. Got any ideas why the screws don't make any difference. thanks again! Bob

You will have to pull those screws out. I bet those needle heads are well worn.

I just rebuilt the carb. a couple of weeks ago and I couldn't get them to work, so I pulled it apart again and cleaned all the passages with carb cleaner then blew out with compressed air. Then i reassembled it and the needles still didn't do anything. Could I have assembled something wrong? Thanks Bob

Bob did you dig out the old packing before sticking in the new on the high speed screw? It sounds like that screw is not getting in deep enough into the seat which is under that packing to lean it out.

Yes I did dig the packing out and when I installed the new I forgot to put in the needle and I crushed the one that came in the kit. Got another one (cost 4 bucks seperatly) this time i remembered to put the needle in and I tightened it down. Maybe I didn't tighten the brass fitting down enough? How far should I tighten it? I thought i put it in as far as it was before. Should I try backing the needle out a couple turns and try tightening down the brass nut somemore?I am worried if I crush the packing nut to much parts of it will get inside the carb. Thanks again!!! Bob

If the screw head is all the way against the packing nut, I would turn that nut in another 1/2 turn to a full turn so the screw is closer to the seat. That seems to be the problem in this case.

Help!! Red I tightened the packing nut in some but still couldn't get the needle to seat
so I started it up and adjusted the idle screw first it seemed to run real good with the screw all the way in. I thought this was strange but it sounded good and wasn't smoking so next I went to adjust the main screw, when I went to bring the throttle all the way up, it accelerated at then died! So i brung the throttle back down and tried starting it again, it started but would only run for a 2 or 3 seconds then die again. So I thought maybe the idle screw all the way in was the problem, so I turned it 1 and 1/2 turns out and got the tractor started but it still died in 2 to 3 seconds. I tried turning the packing nut back out to where it was but the tractor still only runs for a few seconds. I noticed it is harder to get started now. Do you think maybe I crushed the packing nut and pieces of it got sucked into the carb? Any help would be appreciated!!!! Thanks Bob

Bob I hope you left that needle in when you tighened it down. If not, you are back to replacing the packing material again. :(

Yes I did leave the needle in. I found that it will only run now with the choke about 3/4 of the way on. I tried turning the screws while fiddling with the choke. But I can't get it to run without the choke. Tommorrow I'm going to take the carb. apart and see what i can find. I took the plug at the bottom of the carb out and i 've got good gas flow. Do you know any other things I could check for? thanks Bob
