    Oliver OC-3's Final Drive

    I did crawl to the inside, but all I saw were flathead screws in about the same position as the mounting bolts on the outside, so I dismissed them as drain plugs. ...so that was a bad assumption. I'll get a large screwdriver and crawl back under there and give them a try. Thanks for your...

    Oliver OC-3's Final Drive

    I have a question regarding the Oliver OC-3’s final drive, for I admit that I must have my head screwed on wrong because things are not making any sense. Here is an excerpt from the OC-3’s manual: My problem is, I can’t find the drain plug on the final drive:

    Thanks Mike! I really appreciate your pointing me in the right direction. I found that alternator in Amazon for about $80. My neighbor and I fabricated this bracket to replace the one that carried the old generator: I have a question regarding wiring this alternator: ...

    My neighbor and I just bought an Oliver OC-3 crawler that has been sitting for a few years. It is equipped with backhoe and it runs from a Hercules four piston gas engine. We got it to start while cold, but when it warms up the engine dies and it refuses to restart until it completely cools...

    I think I am going to need a little help here: Has anyone added a 12 volt charging system to an Oliver OC-3? I would really like to know how you did it. I ordered an alternator from Yesterday s tractors which was suppose to be for the OC-3, but apparently there ain t no such thing! Following...

    The OC-3 is home and we have been working on it lots to be done. So far, we ve flushed out the cooling system, changed the engine oil, changed the transmission/differential oil, we flushed the hydraulic oil a couple of times, but there is still some water remaining. I ve read that some people...

    Placing wooden pads on each track was not a good way to cushion the crawler s travel upon paved roads, so Adam got the idea of cutting up the rubber tracks used on some tractors. He got one that was used up from a tire shop. Cutting it up was quite a chore we ended up using a chainsaw, but in...

    ... so, one less mystery! Thanks so much for your help, Warbaby. I looked up the shifting pattern for a 3 speed ford transmission and it goes like this: What remains now is for us to head back to the tractor to learn how to drive the thing! This post was edited by mudmuckgrease on...

    Hello folks! Following Is an update to our attempts to get this Oliver OC-3 home. Added to this is a mystery concerning its transmission: There are two of them! I changed out the carburetor with a new one from Yesterday s Tractors. The engine now runs well and we can now keep it running while...

    So now my 9N has a winch and a trailer hitch

    My poor old 9N just got saddled with two new chores: I got tired of manually hauling firewood up from an arroyo. There are four 5/8" bolts attaching the winch's base to the tractor's front axle. ... so, as long as I don't try to drag something heaver than the 9N, I should be OK. This one was...

    So now my 9N has a winch and a trailer hitch

    Thanks for the warning, Mitchford. Wisdom comes at a price: Pain and regrets, but if you are smart and can learn from other people's mistakes, you can skip the pain and regrets part of gaining wisdom. I will heed your photos and disconnect my invention. :wink: This post was edited by...

    Oliver OC-3 crawler

    I ve tried adjusting both idle and running mixtures with no favorable result, so I figured the carb is toast. It doesn t have its brass ID tag, so I don t know what rebuild kit is right for it plus, it mates to the intake manifold via two 1/4" studs, but I can only order a carburetor with 5/16"...

    I hope that isn't the problem with our OC-3. I really don't want to mess with that magneto out in the field. We ordered a new carburetor and intake/exhaust manifold from OliverCrawlers.com - hope to receive it soon. Yesterday, we drove out there to play with it - it starts easily and we let it...

    Thanks Warbaby We will change the capacitor on our next visit. The way that the mag is situated, it is near impossible to work on the points without removing the mag from the governor and I really want to avoid doing that in the field - little to no experience with magnetos and a fear of messing...

    Yaa ... vacuum in the gas tank is something I've seen before ... The gas line has a glass bowl that I keep an eye on. As long as it is full to the top, I figure I've got gas flowing. My issue is with the line itself - numerous kinks.

    Aren't they 2 cycle carbs? I was tempted to use an old 9N carb that I had laying around, but the studs that go into the manifold are 5/16" and the manifold will only take 1/4" studs.

    Thanks for the reply, 560Dennis. A leak in the intake manifold is something I will defiantly check. I didn't think of that. As far as the ignition system is concerned: This is another cringe factor. The generator is completely disconnected and a 12 volt battery is directly running the...

    Two good ideas, but to answer them: No. I was in the field and all I had was a can of carb cleaner. What I did was pull the carburetor and I brought it home with me where I have the tools to do a better job. I ordered a rebuild kit based on the gasket patterns. It will arrive this Monday - all...

    Hi, 2X4. No, I checked for that. The engine doesn't get very hot before shutting down. Its 3:00AM in the morning here. I just woke up worrying about this problem - sticks to me like the smell of old gear oil! ... maybe the problem is electrical. This old gal's fired by a magneto, but the...
