Hey Guys looking for some help with my new oc-3 I bought. On the tag it is marked F3A ser# DP6518. Could anyone tell me what year its is. Also, the choke is messed up. The butterfly valve is free to spin around(is there a stop on it?). The choke to control rod attach point is broke so it is only a nub sticking out of the carb. Can I get a new pivot shaft with the attach point? or do I need a new lower half of the carb? Not really sure even the model of carb? HELP! It is a Marvel Schebler. Could someone help point me in the right direction. Thanks in advance
If you do not mind look at that serial number again. The 2 letters go together no number in between. 3FA would be a prefix for a later Cletrac General wheel tractor. I don't understand the DP letters either.
will do...I am almost positive that is the way it is stamped. Will be able to get back to you in a few days. Thanks
The numbers that you posted sound like they are on a serial number tag for an Anderson blade. The Anderson tag is usually on the sheet metal near the bottom of the radiator, right side. F3A is a dozer blade for the OC3, two cylinders mounted along the frame sides and the hydraulic reservior mounted up next to the right side of the gas tank. The serial # that you posted would be consistant with an Anderson #. The Oliver # would be on the right side of the bellhousing. Of course after 50 years the dozer setup could be long gone.
Here is an example of a F3A Anderson blade

thats exactly it. Im looking at the data plate on the right lower side of the rad housing. Ill take a looksy on the bellhousing. Thanks again!
The carbs on ours are MS TSX 403 and 406.
The difference - the 406 has a mixture adjustment screw for the high speed fuel flow, while the 403 does not.
Both have the choke lever positioned on the outside as mounted on the tractor.
There are a raft of others that will fit (same updraft config, same venturi and mounting hole sizes), but the choke levers and/or the main throttle control have different hookup arrangements.
I might have a spare choke shaft and butterfly here.

Hey guys...I really appreciate the help. I believe it is in fact a TSX 403 or 406. I found an old MS PDF online which resembles it. The crawler is at property I bought and plan to build on next spring. I have tried to find the markings on the bellhousing. Could only see 10 o clock to about 3 o clock on the bell housing. I have to go at it with a wire brush and a mirror to see more. I will eventually get some pics of it and can share via pm's.
thunderbaysteve@hotmail.com . I bought the crawler down the road. It has been very poorly maintained. Bad welds and nail cotter pins...you get the drift. Missing a raft of orginal parts and I believe the right front cog wheel(pls correct me on my terms) is rubbing bad(not the proper install or even proper wheel perhaps). Found parts books for sale $20(+shipping to Canada) or so. Dont really have the extra $ to spare. Wish I could name the pins, bolts, and nuts I need. Jack in New Brunswick, nice to see you have some spares around. Love the East Coast...I used to visit Moncton every other weekend for a couple years. Miss it. Anyways, If you could help me out with parts i'd appreciate it. If at all possible, if anyone could spare a digital copy of parts manual it would help me talk english to you guys. I can't get to the computer often, so pls be patient with me. All I know is that it is an Olver OC3 with an Anderson F3A blade(thanks Mike GT4, looks exactly as the syrup hauling machine...love it!) I got it running before I bought it....and ran it on...off a trailer, and ran it again this year to move it closer to my fathers garage. A friend sealed up my rad(must has bumped into fan an has previous repairs to it). It flows and doesnt leak now. Oil and filter(cleaned check valve out too). Oil is sludgy...have another filter to for another change soon. Read about (I have operator manual) the screen cleaning. May need to do to rid it of the mucky oil? (need to remove blade eh?) Choke is gone. Just a little chewed up brass nub off carb. Plate spins around freely.
Questionshould it normally spin completely around or is it missing a stop in the carb...will a choke plate shaft solve this? and does the shaft come out by just removing plate screws and sliding out? Cleaned up the carb and fuel/air passages, but left choke. I can get er runnin by hand, warm it up and use some bailing wire to keep choke open and move it (the few times I have had it running). Need to tighten fan(is the tool still around?) Seized...tried to use a punch but to joy, been soaking it the last few visits(tips?) Gas tank was polluted. Running it off an old snowblower tank for these test runs. Got tank cleaned out good and the sediment trap is pactch brazed and leaky. I removed(until I find a proper trap)and installed a hose fitting(for now) will run filter and a spigot until trap is found. Parking it for the winter soon(dont have time and visitation as I would like. I want to gather parts and info so I can hit it up in the spring. Its the only peice of machinery I can afford. I have 150 acres of land and would like to do some work(skidding logs, maintaining the new logging road in the back. Time is precoius! Have 2.5year old twins and expecting in May! Not much tinker time on my hands. Appreciate any info and knowledge/experience you can shed on me. Thanks!
