MTZ Tractors - Current Models / 1220.4 Clutch adjustment
« Last post by damengineer on December 29, 2018, 10:25:41 PM »
I have to adjust the dual plate clutch on the 1220.  I was moving a loot of hay and under a deadline Christmas Morning!!  I was using it in Reverse 1st gear high range and Forward 1st gear high range.  The clutch must have slipped some when starting forward as it is now slipping after 60 bales.  Adjusting the clutch by the  methond in the owners and disassembly manual is not so straightforward.  This clutch is different from the dual plate clutches I am used to..

Not sure on the 825...but... what you have should be all there is..1control lever for the 3pt hitch lever(as shown), the 3 levers you mention would likely be the 3- SCV control levers for the hydraulics. On my 8345 the draft control lever is on the front left side of the seat platform(under the seat). The rod you mention at the rear by the throttle/hyd. control is the 3pt hitch lock - hitch can be locked in the 'up' position. If memory serves... there is an adjustable sliding stop in the 3pt control mount. B.

We do use a block heater and it stars great when itís being used but itís hard to plug in when itís not near the barn. We also use ether but as a diesel mechanic I just cringe when I use that stuff. I guess Iíll just leave it. I have never seen a heater like this. I was hoping it would have glow plugs which would be an easy repair

Yes i was of the same opinion and tried to get it to work.  I didn't have issues with wiring it just didn't seem to help much and you still had to crank the engine so much. Which was frusterating as a little shot of ether and its running right away. I was trying it on the bench and accidently burned the little element out.  It all comes apart quite easly actually.  So I made a plate and mounted on another brand actually from a MF tractor i got from AGCO as it was cheaper then the one from Belarus.  Works exactly the same but still didnt seem to be effective enough. So back to the ether can which when used properly works fine

I can probably dig around for wiring diagram for you if you like Also the operators manual has it in it. I'd have to look there may even be thread on the message board here on the wiring of it.  But personally I wouldn't bother with it as I've never had luck getting them to work well enough to be effective.  The way it works is when you push the button on the dash a little valve opens allowing Diesel to run down on a little element that heats up creating a vapor or even flame in the intake to aid in starting.  I have the same system on another brand of tractor and it works better but still not great or like glow plugs.  My other tractors on the farm use ether starting fluid.  So that's all I've used on my Belarus 825 the last 21 years I've had it and it works good. A $3 can lasts a long time, I just squirt a bit into the air intake on top of the hood.  Much below freezing i just plug it in for a little while. IF its really cool like -30 then it needs to be plugged in several hrs. Also you should be running synthetic in real cool temps if its always parked outside.

In the cooler days of winter I just plug it in and it will start fine. A 1500 watt circulating heater plumbed in and the tractor starts in any weather easy.  Here is a thread on it http://www.mtztractortalk.com/mtz-tractors-old-models/engine-coolant-heater-installation/

I'm trying to repair my neighbors 825. It starts hard in the cold. The light doesn't come on, on the dash. The wiring is an absolute nightmare on this thing. i want to start fresh. Does anyone have a schematic for this circuit ot know how it works? I have no idea what it would draw

Thanks Haymaker. I have a manual - it says there are supposed to be three levers, but there are only two. One is straight, and the one on the right is bent outwards, and looks like the one that is supposed to control the 3 pt in the manual. I didn't get a chance to dig into it over the weekend, but I'll try monkeying around with it some more and get some pictures of the underside. In the manual it says something about changing between draft and position control mode through the access hole under the seat, so I will see if I can figure out what setting it is on and if that affects anything.
