    Default 3510 engine repair

    Just purchased a 3510 with the engine down, have not pulled the cylinder head or oil pan yet. Anyone had to remove their front shaft between front axle and transmission, any tips on removing it ? It also has a FEL and it doesn't have a parking stand, could anyone share the length and diameter of pipe so that I could make one . And any tips or suggestions on how to remove the loader with a dead engine. Is dealer still best option for service information/manual or are there cd/dvd's available ? My FEL is a ML112e . thanks for your help, Danny

    Sounds like a fun project. I have never had a Mahindra, but would love one of
    their HST models to take apart.

    First, you should get all the manuals......I am getting more and more in PDF format
    cuz they save tons of money. Money better spent on new OEM parts.

    On other machines, I have seen roll pins used to secure the MFWD drive
    shaft to its splined couplers. Look for those and pound one of them out.

    Removing FELs off of dead tractors is a bear. I use another tractor and
    boom or fork to lift them off.

    Good luck, and post some pix.

    Thank for your reply dfkrug, I bought this tractor because I needed a small tractor that had a FEL and could handle other attachments and it was inexpensive. I am hoping that it can be repaired without replacing the engine, been here several times reading reviews and talking to people locally before I saw it on tractorhouse. I don't have much experience with farm equipment, but it
    looks like I'm fixing to get my feet wet because this is my first tractor purchase. I will try and take pictures as I go and post them here. I've been pleasantly surprised that there hasn't been more post or that there aren't many 3510's out there which is a bad thing.I could sure use any advise because I know that a lot of you use your tractors everyday.
    I want to thank any of you beforehand with your help and advise.

    If you do not have access to another tractor, I have also seen a automotive engine remover boom or crane used. You can rent one of those at most rental location.

    Before I had any alternatives, I would rent the biggest "cherry-picker" I could find to remove
    and install engines in cars. I got the kind that you tow behind your vehicle. If you can find
    one that lifts high enough, this could work for an FEL on a tractor. Note that the legs of
    a cherry-picker would be under the tractor, which means you would have to lift the FEL
    from the front to roll the tractor out from under the loader.

    You might also consider a hoist suspended from a hayloft beam if you have a conventional
    barn.

    Assuming that your 3510 is built the same as my 4110, the driveshaft from the trans to the front diff isn't too difficult to remove. To begin with you loosen the clamp that is about midway down the tube, this lets the 2 sections of tube slide together thus shortening it. The rear section slides out of the front of the trans and has an "O" ring for sealing. There should be a little tab of metal on the tube back just in front of the trans, this is for tapping on gently with a hammer to get the tube out and/or back into the trans. The front tube has a small ear on it and a small bolt holds it to the front differential, remove this and you can move the collapsed tubes back & forth along the actual driveshaft inside. At each end of the driveshaft you'll see the splined collar with a snap ring on the shaft on one side of the collar. Using snap ring pliers open this snap ring and slide it down the driveshaft a little ways and this will allow the collar to slide as well, disengaging it from the corresponding shaft it attaches to. It is the same at both ends - once you have both collars slid back the whole driveshaft and tube assy will fall right down in your hands or on your head if you're not careful !! There is no fluid/oil inside this tube assy, just the driveshaft. If there is fluid you have a leak - 90w gear oil from the front diff or hydraulic fluid from the trans. Good luck on your project !!

    My tractor is at the farm, I will measure the FEL stand when I go. I can tell you the stand pipe installed keeps the bucket about 6" off the ground when level. The bucket rolled forward kicks the back of the frame up off the post so the tractor can back away. Some sort of lifting device capable of the handling the loader weight plus or a overhead winch would be required to get the FEL off and moved out of the way. It is pretty heavy and bulky, probably hard to get it balanced to lift and swing. Be careful that the hydraulic lines on the frame are not crushed.

    Good luck!!

    Had time this morning before church to drain engine oil,it did have coolant mixed in it. After I remove FEL will remove glow plugs and ck compression to have a better idea of
    condition rings are in before pulling cylinder head. Do daedong engines have a history of cylinder head or block cracking? Reason for pre/ck's before tear down ? I haven't been able to find an engine overhaul kit and they are very proud of their parts. But I will replace parts if they are needed. Again thanks to all that reply.

    My work hours were swapped around yesterday so I had some time to piddle with the tractor, had a 3 foot piece of 2" pipe and put a 4X6 under it in the loader to use as a parking leg,removed the 2 nuts/washers where it was attached at the rear of loader, it came off very quickly and disconnected lines to loader. Hooked a chain to tractor and was able to move it so we could push it into the garage. Removed hood and side panels,then removed glow plug wiring and
    plugs,#2 glow plug appeared a little rusty so I think that is probably the cylinder that is leaking coolant.Tried to turn engine with a pipe wrench at crankshaft
    couldn't budge it so I removed starter in hopes that starter was stuck in flywheel,no luck there. So I guess the next thing I'll do is remove front drive shaft and oil pan to inspect lower end. As always any response or suggestion is welcomed and thanks to all that reply.Will post progress.

    Remove front shaft for front end(thanks skipmarcy for the help) removed oil pan and rod caps. Bearings were in excellent condition for connecting rods.last night 9/21 after work, removed intake & exhaust manifolds and valve cover. Today I removed cylinder head and found part of the problem. Exhaust valve seat on #2 cylinder had come loose and destroted itself between the head and piston. Going to take head to machine shop to see if it's cracked and can be repaired but will need another piston. Hoping head can be repaired because they are quite expensive. Still trying to get camera to take pic's.
