check the timing now before you even tear it apart , give you experience and it tells you if it is indeed set to specifications. as it is now running and you cant screw things up , then when ready to install pump its a walk in the park!

Hi Rustred

Those were my thoughts too. Check to make sure the timing is set up now then go from there. It starts very well as is so I expect it will be about where it should be already. Its sitting in the shop and no one is likely to touch anything while the pump is off so shouldn't have to worry about anything getting changed. Just have to set #1 at TDC, check for the timing mark on the flywheel and make sure the lines are aligned in the pump behind the little side door and all should be good.

Expect to be looking at about $1000 Cdn. for a rebuild job but the old girl is worth it. Will check the valve clearances once it is back in operation too. Will get a price on injector rebuild as well. Probably would be wise as the pump depends on the injectors to do their job. Son wants to use it for a bit of haying and just a handy yard tractor.
Sorry for the angle of the pic but happens when taken with a cell if you forget to turn it sideways when taking a pic and then want to upload to YT.

nice tractor. you set #1 cyl. at TDC on the COMPRESSION stroke. there is TWO TDC's. that's why you watch #6 cyl. when setting the valves. each cyl. has a running mate. when the running mate's valves are rockin , the cyl you want to adjust is on TDC on the compression stroke. handy yard tractor... hummm? give me forty acres an i'll turn this rig around!

Hi Rustred

Yes you are totally correct pistons reach TDC twice on four cycle engines.

One time on compression and the second time on exhaust. With #1 on TDC compression #6 will be on TDC exhaust just prior to the intake valve opening if my memory serves me correctly.

Actually the G1000 is an amazingly short turning tractor for it size in its day. We used to have a Massy Ferguson super 95, similar to the MM G6 and that one needed between 40 and 41 acres to turn around. You usually had to make at least three passes for headlands depending on the size of tillage tool you were pulling.

Hi molinegb

You are perking my curiosity about your supplier for the kit for the injector pump. Not sure if you can mention a supplier on here but that sounds tantalizing.

On another note:

I think we had an online chat several years ago about an M670. What was the cause of it not wanting to start? I have always been curious to know what the results were on that one. I think it was an LPG originally if memory serves me right.

Most pumps like yours I repair, test, and return run 300-400. long as the pump hydraulic head is good. I'd leave the injectors alone too, unless there's a known problem with them. They don't cause as much trouble as most think they do. Just my thoughts of forty plus years and counting of diesel injection repair..

Hi Dieseltech

So you are suggesting have the pump repaired and leave the injectors be. Since it will start and run I don't think there is anything broken inside the pump. But we have no plans for running it further until repairs are made since I have read where it can lock up and break a shaft in the pump.

You price sounds reasonable however I am not in the US. So a number of factors come into play, shipping and exchange rate of around 35%. But could still be less than around here. I'm assuming you are in the US of course.

I do have to replace an O-ring where one of the injectors is seeping engine oil. But that is to be expected on a 53 year old tractor.

Thanks for your suggestions as I appreciate all the information you and everyone else has willingly shared.

Hi rustred

I live in Southwestern Manitoba. Brandon would be our closest city.
