Bit of combine help please

[bobk]

Replaced the drum belt on dommy 86

However on refitting the main drive belt I can't see how you tension it up on the spring loaded pulley

@Gapples @carbonfibre farmer @Phil P or anyone else thanks

Sorry @bobk thats not a model I’m familiar with so can’t be much help. Have you not got an ops manual? They usually give you the procedure for replacing and tensioning all the belts.

Dominators are a very old model now

You'd be much better off with a Lexion ☺

You have got the lever engaged in the cab?

There is no lever , it's direct drive off the engine .

Claas Dominator 108 belt adjustment.

Just fitted a new threshing drive belt to the above combine. And because it now engages very harshly and noisily, I've consulted the book. I'm I being stupid? Is the measurement quoted mm? 20+5, is I assume 25mm. Not very sure as on the same page it says 5-7mm for a diffent measurement.

Yes but the drum needs engaging.

 

[Andy26]

Is that belt not slack when the drum is disengaged?

What difference will that make ?

It's not the drum belt . that's done .

Drum belt is the other side of the combine.

 

[bobk]

Drum belt is the other side of the combine.

The drum is the big pulley at the bottom of the photo

 

[MF-ANDY]

That is not the drum pulley or the drum belt. Both of those are on the other side.
That is the separator engagement belt and the big pulley is on the impellor shaft. The belt will be slack until you engage the sperator lever the there will be a measurement for the spring on the linkage. I will have a look in my book when I get time.

I give up ............

 

[MF-ANDY]

Well if you are talking about the drum belt and how to tighten it why have you posted a picture of that side. If it's the drum belt with the variable pulleys then I don't think there us an adjustment

I'm not talking about the drum belt , that was the job , the problem is the tensioner on the drive belt , as shown in the pictures

 

[MF-ANDY]

Then as I said AFAIK the separator needs to be engaged then there is a spring measurement
