Hey guys, I have a very late ‘84 L3 and a service training manual for a 1980 L2. Should this pretty well cover the L3, with the exception of the injector pump and Dennison hydro? I’m thinking by 1980 the L2 was pretty much identical to the coming L3, but wanted to check. Ideally I’d like to find a service manual for an L3, but if this works, I may just settle with it. Thanks! |

The L2 is not the same machine as the late L3's, at all. The later L3, the break was 28,001, has even more updates than the early L3. Larger shafts and drives and bearings. Me thinks the walkers are longer too. Larger cleaning area in the L3. Chaffers and sieves from an early L3 will not fit the late L3. Service and operator manual my be similar but the parts book from an L2 to a late L3 will be very different. We have a part's book for the our L3 and most pages will start off with serial number prior to or after 28,001. "I think" the L3 past the 28,001 serial number in mid 84, so you should have the 28+ L3. Be sure you know your serial number prior to ordering parts. I wish you the best of luck.

Ok, I wasn’t aware of that. Yes, it’s above 28,000, somewhere around a 28,6xx number. I thought the longer shoe came in ‘79 on the L2s? Did they lengthen it yet again on late L3s? I could’ve sworn I took a chaffer from an L2 and put it in an ‘85 L3 about 5 years ago. |

I just looked up the part numbers, the chaffer for sn effective 28001 is the same for M3, L3 but the sieve is not. Wallkers also different, the M3 has 4 the L3 has 5. Leon B MO ------------- Uncle always said "Fill the back of the shovel and the front will take care of itself". |

I have been around the Gleaner MH's from 1975 model to 83 model I think was the newest. Lots of different things thru the years.Some like rerouteing chains may have been cost cuttings as the chains where shorter. But many like larger shafts was a improvement in longevity of the machine. The 75 had the back axle shear the pivot shaft the 78 was made of much thicker steel. Lucky it broke when it did, just came from 200 acres most of it the leveler maxed out and still not level. Drove them right thru town, and cutting very level stuff for several hours. Drive the pick up right to the machine to haul the axle to the welding shop. Question for Leon how could the chaffer from a M3 be the same as the L3 ? So is this just a typo.

Long shoe L2 should fit the same sieves, both top chaffer and bottom sieve, as any year L3. Walkers are the same from the first L through the last L3. I really don't think there are a whole lot of changes from the long shoe L2 to the last L3 other than maybe some minor available options maybe. Late L3 has a slightly better rear axle but the assembly will easily swap. ------------- -- --- .... .- -- -- .- -.. / .-- .- ... / .- / -- ..- .-. -.. . .-. .. -. --. / -.-. .... .. .-.. -.. / .-. .- .--. .. ... - Wink I am a Russian Bot |

I apologize, the chaffers have different part #'s from M3 to L3 according to Agco parts book page # 274 as do the seives. Will they inter change...I don't know. This info is for M3-L3 over 28001. ------------- Uncle always said "Fill the back of the shovel and the front will take care of itself". |

Interesting about the walkers being different. I only remember having to clean walkers on a MH or MH2 once. In stuff with 8 to 10 foot high mustard and 3 foot high barley. Could of been left for how much grain but was share crop rented, cut it all to keep landlord happy. With the AC grain loss monitor never ever had a walker loss always on the sieves. Open them up and put more air to it generally fixed it. Unless you needed to keep low test weight grain. Which in some situations was about all of it. Old Massy Harris 90's or JD 95;s lots of times.

That manual should cover it, 1980 was the first "modern" year as far as electrical and hydraulics. 77 was essentially an L with the newer cab and feeder beater drive. 78 brought the new style bin and clean grain system, hidden HVAC lines in cab pillar, 6x6 hydro. 79 brought wide range variable cylinder drive, better worklight package. 80 brought improved electrical, hydraulics, black engines, long shoe, a few shafts were beefed up, reworked cooling system on big engine, etc. 81 brought updated cab interior. 82 brought a few updates like 1 piece main pulley and extra brace on rear ladder deck/ auger cradle. 83 brought ambac injection pump 84, first 200 units had 6x6, after that had 7.25x7.25 Dennison. I'll have to hit the books to refresh my memory on the 84-85 updates. Yes there were updates, but the 1980 service manual will be plenty accurate for most things. Walkers never changed, shoe was just 79 and older and 80 and newer, and they are fully interchangeable. I got in a 81 that they wrecked the shoe and it has a short in there, and numerous Ls and early L2s had the long swapped in. ------------- Gleaner: the properly engineered and built combine. If you need parts for your Gleaner, we are parting out A's through L2's, so we may be able to help. |

This is what I’ve got. From what I understand it was given to technicians during training events when something new came out. https://photos.app.goo.gl/MF387eFc7EAmBU226" rel="nofollow - https://photos.app.goo.gl/MF387eFc7EAmBU226 |

| Thank you GM Guy, that’s exactly what I was looking for. I figured they should be pretty similar. |
