    I have a Mitsubishi BD2G that when you pull the lft steering lever it will stop the machine. May move a little but you can hold the brake just a little and will not move. The right steering lever works fine. Where should i start looking. Also where can i find a service manual?

    :(When you pull the left lever back does the right track still pull? Sounds like your clutch pack on the left is gone. I had a simular problem with mine and the brake band was shot, replaced the right side for 700.00. Have you tried any adjustments to the brakes or clutch rods? It may just be an simple adjustment.
    The right track should continue to pull when you pull the left lever back it releases the hydraulic pressure on the left and applies full pressure to the right side. You can get books from Rhine equip @800-536-3335 ask for Jay. They will probably have to order them from Mitsubishi but it's worth the wait and cost.
    I have a set if you need specs on how to do the adjustments, just let me know.:)

    No the right track will not pull. Seems like it just kills hyd flow to both drives. Only the one side does it. I will call and get a manual ordered but if you could spare the procedures for now that would be great.

    Look under the seat and you will see two 15/16 nuts, one on each side of the hydraulic valve. These are kinda hard to get to, I used a socket and ratchet to reach them.You will have to use a shallow socket or a box in wrench, DON'T use an open end if you can avoid it. Tighten these all the way down and then back off 2&3/4 turns. They may be hard to tighten but keep trying, I had to use a cheater bar to loosen mine.:mad: Make sure the rods and linkage to the valves are hooked up and travel is equal on both sides. When trying to move forward without pulling the levers back do both tracks pull even? You can put the blade down to cause pressure, put it in 1st and then watch both tracks to see if they pull. That will tell you if the clutches are good. If the clutches are good on both sides the tracks will pull equal, if not the right side will slip and not engage. I forgot to ask if you have a manual or a power shift trans, if it is a power shift then you may have another problem:(. Let me know what happens. By they way, where are you?

    The nuts your talking about are they under the inspection plate? If your traveling and you pull the left lever it will start to tun then stop but if you release the lever just a litttle it will try to go again. Both tracks pull fine. Pull right lever and it turns right no problem. Just when you pull left lever.

    The Mitsubishi BD2 are good little machines,which often came from Japanese rental fleets.Often,they sat in cold weather,doing little work...& sometimes the steering clutches bonded up.They often came equipped with apex plate swamp tracks.
    You'll likely need to renew the steering discs,which can be got from steeringclutch.com.
    Working on the steering is a bit hard,but better than on other machines.
    Steering is dry type.
    I can sell you copied books,& have some parts contacts.

    PM me.

    Okay
    Got my mmanual and did all the adjustments. THey were out some but still same thing. If your traveling in forward or reverse and pull the left lever sometimes it tries to turn and sometimes it wont. The right lever works fine. I suppose i just need to pull it apart and replace clutches? Its wierd tho the way the machienw ill somtimes still try to turn?

    Yeah I think you will find that either you have oil in the right steering clutch case or your clutches and steel disc are bad. Hopefully that is all. I have the drums, clutches, and the steel disc on the shelf for times like this. If it has oil in the case then you will also need to rebuild the release cylinder. I'm doing one in teh shop now and they are pretty nice to work on really. If you need anything send me a pm.

    I am having brake trouble on my BD2F , the right brake compartment is oily.

    How do I remove the inspection plate ? Something is holding it down. The brake adjustment bolt refuses to turn , too. Is it supposed to be hard to turn?

    As stated in the post above , is the oil coming from a leaking hydraulic cylinder ? Or would it be rear end grease from a bad shaft seal?

    HELP!

    I don't know anything about your machine, but i learned a long time ago that those dry steering brakes are scrap if you get lube on them. Years ago, we struggled with a 500e that simply would not steer. Finally got rid of it, and then years later realized its was because the brake bands, once they have lube on the lining, they are junk. Looking back i feel so stupid...

    I our case, you pulled the lever, the clutch would disengage(release) but the brake wouldn't grab, so the machine kept traveling with a slight drift in the desired direction. Doesn't sound like your problem though...

    Got the same problem with a seized left clutch... spent all day trying to get it out but the outer drum is locked solid to the cluch discs so no joy. One more try with a tool I made to try and press them together and if that doesn't work I might have to admit defeat and cut the drum :(

    Right clutch and brake came out easily and seems fine. Can anyone tell me what thickness the clutch plates and steel plates should be or what to look for to check if they should be replaced. Also whats the lining thickness on the brake band supposed to be?

    Diagram of the steering clutches can be found here

    http://www.tpaktopc.net/PDFs/BD2G%20STEERING%20CLUTCH%20PARTS.pdf

    I assume you have removed the seat, panels and top covers and disconnected the brake bands. Then you need to remove the bolts from each side of the drum. They are part 34 on the drawing and there are 10 each side from memory. You will need to rotate the track a little to get to them all. I do this by using a jack under one of the track grousers at the back of the tracks. Once all the bolts are out the drum and clutch pack need to be loosened and moved away from their attaching flanges before you will be able to lift them out as there are steps in both mating faces.

    I cannot post new thread, so can i ask where to get a hydraulic filter for our BD2G?
    It is about an '86. I will check books and serial number, but where do you get parts, etc?

    Thanks,
    Jerry

    I have found aftermarket replacements for the engine oil, fuel and air filters but not the hydraulics. I have the details at home and will post them in the next few days.

    For the hydraulics I ended up having to buy a genuine replacement filter as no one I tried was able to match it. Genuine parts generally seem to be available though dealers of mitsubishi graders/excavators etc. In australia that is BT equipment and in the states I believe Rhine equipment supply parts, but there is probably others.

    engine lube - BT292
    fuel - BF1110
    air - PA1667-FN

    The genuine mitsubishi hydraulics filter part number is 58873-12200.
