OC sort of....Rumely 6

Got one running this winter that had the engine and the clutch stuck . The engine was not hard to get unstuck valves had it stuck 3 of them in the end . The clutch was a different story had to separate tractor and found the pilot bearing froze up then found the rear plate was cracked ,had to remove clutch and have plate repaired.. The Rumley 6 had a oil bath clutch that is different than anything I had ever been into , adjustment is critical .I have seen several carbs used on this machine mine has a K5 zenith and runs well . Do not hold me to it but I think the parts book lists a zenith 169 as the original . I saw one last week with I think A zenith 63.They are like any other , clean fuel , proper timing ,good compression and they run . I was lucky enough to get one with Elec. start but it will fire up on the crank to . They are a smooth running machine . They are a non sleeved block mine is bored 60 over. I know A fellow forum member that just got another 6 running his has even another different carb. he can chime in if he wants to. I would like to put mine on a saw mill one day I think it would do well . For a tractor that so few were produced it seems that several survived that speaks well for them   

My '35 allis sales brochure shows the rumely 6a still available. We have a orange carcass of one. They are good tractor just slow because of the lightweight oilpull designed rear end.

copy and paste from YT Mag.com Rumely 6 used a Waukesha 6 cyl. L head built to Advance-Rumely Specifications. I am not familiar with the MZA engines so I can't tell you anything about them. Rumely built 804 6A's in 1931. The engines in them were 4.25x4.75 and had babbit bearings. I don't remember the engine tag saying anything about MZA. The magneto drives off the water pump on the left hand side of the engine. Rings are easy enough to get - 1/4" oil ring like an unstyled B JD, compression rings were 1/8". Got ours from Dave Reed at Otto Gas Engine. You can get a reproduction manifold. If you don't find the parts, try an ad in "Rumely Collectors News" www.rumely.com. The color is Brewster Green which was also used on '49 Mack Trucks, Martin Senour 99L-2599 or duPont Dulux 24166. I mixed my own with Hunter Green and black until it looked right. Matched perfectly.

Anyone have pictures of one with lights on it I have one with a starter looks like lights would bolt on but have never seen one with lights on it . They sure run smooth

I have a rear fender bracket and one broken radiator bracket. We need to get together and have some cast as I have about 10 lights. If you count the carcasses we have 5 6A's

The Waukesha's in rumelys carry a 6a serial number and not Waukesha serial #'s.
Lee I was told you have custom 6a. Sounds like an improvement to me and would be interested in seeing some pics of it!

I would like to comment on a couple of things about the rumely 6 on the sales brochure Lee posted . First note the round spoke wheels . AC did a lot of things to move the 800 Rumley tractors they acquired when they bought the company it took them from 1931 to 1936 to get rid of them . They offered them on rubber in 35 with the round spokes as an option . Note the exhaust going straight up out of the hood , another modification AC made most the early Rumley tractors had a turn out elbow just above the manifold . The Rumley 6 I own has both these features and I believe they are factory . I also believe AC took Rumley 6 power unit engines and built tractors out of them . I know I will get some argument on this but I know where there is a Rumley 6 tractor with a AC model A bell housing and rear end . It has NO adapter plate it has holes machined in the bell housing and bolts directly . It uses A different flywheel than the Rumley 6 with the oil bath clutch again the flywheel is machined to fit . To much machining for a farmer in 1936 and to well done . This tractor I am referring to has a industrial type rear wheel set up I believe was produced by AC for some type of industrial application. All of this done to eliminate Rumley stock or to meet a certain need .

This is the tractor by the way, I thought I posted this pic before but maybe not. All original except for paint, the guy who owned this only bought really nice tractors and took good care of them. Been stored inside for 20+ years and turned over every year so not stuck. Should clean up real nice.

To clean the fuel tank out i would get it as clean as you can mechanicly by shaking bbs or rocks or whatever also try working a pressure washer around in there as good as you can get it. There is a coating you can put in that seals the remainder of the rust or whatever is in there off you just put a quart or so in, roll it around and pour the rest out and let it dry. I can't remember the name of it but i have bought it at napa and had really good results

What is the make and model number on the carb? If it's a zenith I should have the specs and part numbers for it.   Matt

I rebuild all my own carbs. White chalky, battery acid looking powder is common on antique tractors. So far have always been able to clean up good and have enough left to repair with jb wield. The main areas are where it seals. Mine has a Zenith model 62.

Finally!!   LOL

The Carburetor Shop has kits for Zenith 156, they are made to order though with 12-15 week turn around http://www.thecarburetorshop.com/TrackitsA.htm#TracAdva

Have an older restored one at our show grounds and I'm going to tune it up and try to get running. Anything to look out for, oils/fluids, spark plugs, carb rebuilding etc? Have a service manual but it's vague. Also the gas tank has been dry but is crusty, thinking of taking it off and shaking some rocks in it then blow out, anything else I should do to really clean it? Any help is appreciated, I know the knowledge is rare on these.
