Hi everybody. Has anyone fitted or used a COM on an 8 speed 930 and are there any problems in fitting 3pt linkage to the 930. Regards - Michael

The COM designed for the 60 HP 830 is not as useful with more horsepower in certain situations. It is hard for me to explain but with the converter locked up and 100 hp the drawbar pull is higher than the amount you can get through the converter at stall speed. I think our charge pressure may be a little low and higher charge pressure will increase the torque the converter will transmit. (increases heat too) COM is still handy for downshifting for headland turns while keeping the PTO speed up or starting a load smoothly on the road, like a full load of manure at the end of the lane.

Also we try to be nice to the lock-up clutch by backing of the throttle as you shift into direct drive. The first time I pulled the 830 naturally aspirated I picked too high of a gear when i shifted into COM the tractor just stopped because it was under a hard pull.

Basically I don't think you will be able to pull much more with a 930 in COM as you would with an 830 in COM, but if you you want the ability to shift on the go under light load it may be useful. Once the lock up clutch is engaged in will hold a lot of power, the 830, with the turbo on, has shown 150 on the dyno and we haven't slipped the lockup clutch....yet.

Have Fun, Joel Harnish

Thanks mEl - the capacity if the COM was certainly a concern to me, but what you have said sounds good. Thanks very much -regards - Michael.

Just read this post and thought I'd chip in. The COM implant into a 930 would be feasable with a little ingenuity. The internal shaft into the dual range would have to be changed as well as the complete center housing, a COM radiator and piping would have to be installed and I'm sure there would be a difference in length in the housings to consider fo steering and throttle linkages , etc.
As far as the unit not taking the torque of the 930 engine, I have had 830's with home made turbo setups running in 830s for many years at HP levels that mose 930's will never see. Jim Harnish, a friend who has posted pictures of his project tractor will attest to the COM strength as he has built a 830 with a turbo 336 which I am sure is running well over 100 HP into a COM.
Whether this project is feasable is for you to decide, but the COM strength issue is a non issue as far as I am concerned. mEl.

Thanks to both for your replies. The fuel tank is not an issue, as the 930's sold here in Australia with adjustable axles were fitted with the tanks with the pockets. What are the differences between the 8 speed in the 830's and 930's? They appear to be the same on the outside and during the 1960's we upgraded the 830 gearboxes with parts out of the 930 transmissions, and made them more reliable. Regards - Michael.

Your message does not make a lot of sense. COM is a torque converter drive transmission, and no they do not fit a 930. I do not think the converter would handle the torque of the 401 engine. If your question is about adding a DOM (draft-o-matic) three point to a 8 speed 930, yes it is a direct bolt on. You will have to get into the transmission to get the sensing link out the bottom of the trans. housing to make it work properly.

Another after thought. If you are adding a DOM to a 930 Western you might have to change the fuel tank to get the pockets for the 3 point arms to go up into.

Almost seems like it would be cheaper and less hassle to find another 930 with DOM on it!! Maybe not cheaper but surely less work!!
