I recently got an early 80s i think MF80. i would like to know a few things about it namely what oils go where and how to check their levels and where their drain plugs are also how to keep it in neutral since there is a high low shifter on the dash and a forward and a reverse pedal but nothing seems to keep it in neutral so some pointers there would be amazing! ok so i know the hydraulic fluid has a pressure release valve and i think that is on or near the fill cap but is there a dipstick or eyelet or bleeder to tell when it is full so i dont overfill it? also what type of hydraulic fluid does it take? same with the trans which i dont know where the fill it and the diff and maybe the power steering. any help on these would be amazing. also does anyone know where to get a seal kit for the swing cylinders they are leaking enough to be annoying and the right side curl piston is seeping. any help would be great ive attached pics so any more info you all can give me on it would be appreciated.
An MF80 is a big strong machine with a 6-354 Perkins. Great engine with exceptional fuel economy. Might be a manual online. My best guess is it uses ** Permatran fluid in the trans. Hyd. fluid is probably just AW32 (10 weight) hyd. oil. My former neighbor owned a couple very similar MF70's. The MF80 loader had a 6500lb rated lift capacity. A good seal house should be able to match the seals. I've seen some brochures and manuals online.
awesome thank you for that bit of info. and wow that means it can almost lift a 40 foot container actually if the bucket was replaced with forks because the weight is closer to the pivot it might be able to lift a 40 ft container. well im not going to have any issues lifting things around my house with it thats for sure!
You might lose lift capacity with forks. Depends where it's measured. Some are at the pivot pin. I do remember my neighbor saying the MF70 had incredible lifting power and it's rated at 5500lbs. An MF80 is 1000lbs. more.
oh thats a good point still way way way more capacity than i need around the house heck i dont even need a car lift any more just pick it up with chains through the windows heh. and it sounds like it should be able to drag an empty container into place no problem. i now just need to figure out where to check trans oil and make sure its not low.
Should be able to find manuals online. It will drag seacans no problem. My former came over 1 morning to pull a tandem water truck out of the small ditch beside our driveway. The truck driver was worried a backhoe wouldn't be enough. Neighbor drove up hooked a chain on a bucket hook and backed up. Didn't spin at all on the packed snow driveway. An MF70 weighs about 18,500lbs. and an MF80 is about 22,000lbs. Neighbor said he could drive in snow filled ditches it was so heavy. MF70's were fairly popular. The MF80 came out later but I've only seen 1 in person. I've seen at least 8 MF70's during the 80's and early 90's. There's a video on ** construction equipment that mentions the MF70. They roll one over the side of a steep hill to show how tough it is and the strength of the ROPS. It rolls over 2 or 3 times and the only damage appeared to be a broken front spindle.
wow thats pretty good i kindof feel lucky to have gotten one seems like they are a good machine. unfortunately the ** dealer out here didnt have an operators manual to look it up might try some others see if they can find it. i think there is an operators manual somewhere in the building its parked near but who knows where it is in there.
I think I've seen them online. MF70 is very similar just a little smaller. I think lubricants and such would be the same.
Not hard to find. Try here. https://www.digiagrimanuals.com/massey-ferguson-mf80-loader-parts-manual---80-10003-p.asp They appear to have both operator and parts manuals.
I found a post I made in 2020 concerning manuals for an MF80 and you could get original manuals direct from Agco who owns ** for reasonable prices. MF70 and MF80 are the same owners manual.
i was hoping someone would just know because it and the operators manual for it are one hour in the opposite direction of tractor supply which is one hour away so i was hoping to not have to go out there find the operators manual somewhere in the guys garage then truck it 2 hours to get to town then 2 hours back to the mf80 basically i would rather go to town then truck all the fluids once making a 4 hour round trip rather than a 6 hour round trip.
yeah as my post above states i was hoping not to have to buy another one but heck might be cheaper than the trips
That link I posted is an electronic copy of a manual sent to your email address. You can't get much simpler than that surely......... Also there's no such thing as a free lunch.
You've got about a 45 year old backhoe that isn't supported very much if at all except for the engine and you don't want to pay a reasonable price to get some original manuals for it? You can't expect that you aren't going to need to be fixing things or even doing basic maintenance. If you haven't set aside $1000 or $2000 (at least) for repairs and maintenance or if it was never budgeted you've got a good chance of having a very big expensive piece of lawn art. It's not like Cat, JD or Case that are still made and supported reasonably well. An MF80 was a good machine back in the day but was never as popular as Case or JD so hoping people just happen to have manuals lying around is mostly wishful thinking. An hour away? That's nothing but call and see if a manual can be found before you drive there. Nige is right there's no free lunch. There's also no substitute for a proper manual(s). You don't have to do all the driving in 1 day.
no no the operators manual and the shop manual should be in the garage originals for that machine i was just hoping to avoid a trip out there to find them to look up the oils needed thats all was hoping someone had experience so i could go out there with the proper oils rather than making 2 trips. i also have no problem paying for manuals but the manuals came with it so having a different set of manuals would be unnecessary.
oh i know its an electric copy might save me a trip for the $25 however the manuals are already out there the issue is i wanted to avoid an extra trip so was hoping someone had what kinds of oils i need to bring. but its looking like ill go down there with some new batteries find the shop manual and operators manual and then return with the oils. another reason im hesitant on buying a manual online is it may be for the wrong year as i dont know the year of it however the manuals its coming with are for the correct year
I don't think there were any differences between years. The only differences I've ever seen are you could get 4 lever or 2 lever backhoe controls and cab or open station. I've only seen versions with a Sims cab.
