Combines Gleaner black smoke

[Tom_Russell]

Do you have any better way of showing the neighbors how fast a Gleaner sails through cropsIJ Seriously, you can't see any smoke from my R60 even when it is pushing a 6 row head through 200bu corn at 5.5mph. Tom in MN

Most older Gleaners in our area had the pumps turned up to fight the deep mud we used to have about every other year.We had to turn the pump up on a F-3 I used to own so it could turn those 23.1 rice tires.A friend has an N-6 that smokes like a pulling tractor.In fact in heavy going my 1420 IH rolls the smoke pretty good.You dont see as much smoke from all the newer combines.Since everyone quit plowing 20 years ago we dont have the deep mud we used to have.You rarely hear of a combine getting stuck anymore.

I think all the older Gleaners blew black smoke. Someone once told me that Gleaner fixed the problem with the series 3 conventional machines and I don't notice smoke on the newer machines.

The black smoke was primarily property of the Allis engines. They were last used in the R4,R5,R6, and R7 machines. After that was Deutz then Cummins

The diesel mechanic we use on the farm says the smoke is because of an undersized turbo (on the N6's anyway) and having the fuel turned up just about as high as the engine can stand. AC didn't install a big enough engine, and tuned the heck out of the one they put in the combine.

That was a feature designed into the allis engine in order to help the grain cart operator find the combine in rolling contoured land. Seriously, all the allis engines were smokers, especially the 426. The neighbors run a 7580 that looks like a locomotive going down the road-no load! I don't know if the bosch injectors helped on this or not, but many were converted.

We've found that the smoke is primarily a function of dirty air filters or inj pump turned up above factory setting (thus no longer having a matched turbo size_fuel ratio). Our 7040, 8010 and M2 smoke very little unless under a heavy lugging (i.e., not holding RPM's) load. Our Deutz tractors won't smoke unless subjected to a stalling load. Many of our neighbors here have smokey IH's and JD's, mostly due to the age of their tractors_combines and less than stellar maintenance.

AC engines, from the WD thru the 190XT to the energy crises, had a priority of snappy, rip snorting performance. An owner of an Allis wanted something good to happen when the throttle was snapped and or a load applied. This was accomplished by quick acting governors and big holed injector nozzels and generally lower compression ratios than competition. The trade off was a little slower cranking and the subject at hand 'black smoke'. This was good in the 60's and early '70's understand. (unless you operated an AC dozer in 'Nam- the the VC aimed the morters at your smoke. This led to a project of twin turbocharging to put in more air - Noble Harrison happend by and saw one on the dyno - lightbulbs popped and with Ed Elgin's help and after talking to Terry Wood, a Harvey engineer, AC won almost every class at louisville the next Feb.) Then the energy crunch hit and along came Bosh fuel systems and injectors with smaller holes in some cases and higher boost and less smoke. AC had a bosch kit to change out inj. and lines by the way. Then came Harry lusk and he sold the Company which was working on cam operated injectors and other goodies which are forgotten. Then came the Deutz engines and the Cummins and bye-bye smoke, until you pull the little cover off and ooopps. Bye.

tbran,I was fortunate enough to get to see N D Harrison from Pittsfield,Ill pull his twin turbo 220 Allis a couple of times back in 1969.It made alot of horses for that time peroid.I still have a picture of it somewhere.I remember them chaining it in gear.

Yes, the Mckinnons also ran a lot of his stuff. There was a guy whom I shall not name, who was a klutzz, couldn't make his tractor run, blamed Harrison for it and threatend to sue AC via Harry lusk - said he was not getting the same stuff the Mckinnons were - so lusk sent word out to all AC people - no formal involvement in pulling - end of story. Terry Wood and another engineer or two still helped on the sly for a few yrs though.
