Shopping 9690. What to look for

[sinapisalba]

I am looking at purchasing a 9690 but I have never been around Massey combines (except Super 92s and 510s. But that's another story). I can find my way around a Case Axial flow blindfolded but after climbing around this Massey I have some questions.

Where is the rock trap? I looked at the underside of the feederhouse where they are on a CaseIH but I see nothing that looks like one (hinged door with lever opener). Was the rock trap an option?

Is there a way to look at the impeller area of the rotor. On the Case you remove the halfmoon door at the front. Is there something similar on the 9*90?

Is this wiring bulkhead normal? The way the wires are exposed between the plug and the loom make me think it has been messed with.



Why would anyone pull every second wire on the front concaves but not the rear ones. In the Case I run now, I have the wide spaced concaves in the rear positions and the narrow one at the front. Front is Right, Rear is left, in this picture (taken from the right side of the combine)


OMG the top of the rotor housing is dented upward. Especially where the "transport vanes?" (Case lingo) bolt through it. Is this reparable?



As you can see I suspect this machine has ingested a few rocks. So I would like to see the guts of the machine a little closer. Other than pulling a few concaves are there any easier ways to check out the rub bars and Rotor intake areas?

Thanks for putting up with my newbie questions.

the rock trap is right above the front axel, not in the feederhous like the case ih, its further under the machine then your thinking.
The shaker arms are super suspect, and the top of the rotor chage is not that thick of metal,
I would say that its more then a few rocks...

To not stay case ih,, good deal or good dealer.

I would take out the first wires and not tha back on the mmassey to lower the mog level on the sieves, get as much out in the front and keep the trash in as it goes back. The massey is super agressive at the front of the rotor compared tl the case ih specialty rotor, largest threshing elements are at the front, and as straw would move further back it would just get chewed up more and potentially overloading the sieves. This way the grain would be allowed to escape at the front of the concaves, but still allowing for continued threshing.

It was a good deal, that is until I found the rock damage on the rotor housing. I suspect this machine spent a lot of time with it's header down in the dirt harvesting lentils. The rest of it looks awesome. Little or no wear on the augers, elevators, belts and pulleys. I just want to have a good close look at the internals before I decide. Any similar houred 2388 would be 50% more money. So I don't know.

If the concaves are not damaged I would not worry, that cover is mostly guage steel, agco products are pretty cheaply built at times, the top of the rotor housing shouldnt effect the working at all.
Also the way that looks it might not be rock damage at all. It only is bent up around the vaines, correct. That could be just from the constant pressure of crop mat pushing up on the rotor cover, the rotor design is not like the case ih rotor, it has solid rasp bars that do not allow the crop to move around them
. If the concaves are clean I would not worry about the top damage. But definatly pull your rotor, and hook up with northern farmer and make sure you do the st. johns rotor mod. Save fuel and better threshing.

check the return elevator/auger if it was in a lot of stones, damage will show up where the elevator drops everything into the auger.. use this as "Just another indicator"

a few dents in the top of the rotor and at the return auger is nothing, as long as the concaves are in good condition and the rotor has no damage..

Good Luck

Thanks I'm going to check it out again tomorrow morning. I will give that area a look. I will also try again to find the rock trap, and I will also remove a deflector plate (tin plate in the bottom half of picture #2) so I can get a better look at the rub bars through the concaves. Is there an easy way to have someone manually turn the rotor while I peer in there? The IH design made that easy.

Did Massey have a extended wear option on these machines, because the auger flighting on this thing is incredibly thick. I haven't measured but I would guess somewhere between 3/16" and 1/4". WOW! A big contrast to the Lexions I have been looking at. They are all so thin I could shave with them.

The thick auger flighting was a little gift from cousin Gleaner.

not sure about the 9000 series machines, but I can turn my 8570/8780 rotors with my hand right from the side while looking at it..
the deflector plate isn't tin... you'll need both hands to hang onto it when removing it... I think 9/16'' wrench is what is needed to remove the bolts. I'd take a couple of 1/2'' wrenches just incase..

check under the front beater in the center of machine for wear as this is a wear item, when thin it will have dents or holes on back side. Check outer unloading auger tube, if the seam is on bottom side it will start wearing holes at seam. If top of rotor housing has dimples in it like that it is from rocks & then check the rotor where the rasp bars bolt to the tube & the tube of the rotor will be dented in. Slide the rotor gearbox into neutral & spin rotor to check balance. Just a few areas to look at!!! Good luck.

Is that the 9690 that was for sale in Kindersley at the Case Dealer ?????
