Service Manual for L3

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!

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 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.

Walkers and sieves cannot fit from M series to L series. You would think the walkers would be the same but they aren't. I think the walkers are slightly wider on the M series and of course there are only 4.

May I ask what a "training" SM is ? 

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.

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