grain tank liners

I just looked at an 01 9650w (for sale) and noticed the grain tank had poly liners in the auger troughs. The machine has about 1700 sep hrs and looks pretty good otherwise. It looks to me the auger troughs had worn completly through before the liners were installed--in other words, you could see the damage from underneath the machine. Is this something to be concerned about or is this normal? Is this normal for a machine with 1700 hrs? The man said these liners were installed with self threading screws. So what happens when these poly liners wear through? How many hours can you expect them to last. Anything else I need to look for if I am interested in this machine? Your opinions are appreciated, especially if you have more sense than this old farmer.

How does the rest of the combine look for wear? clean grain elevator and cross auger tubes, feeder house floor and bubble up auger in the grain tank are they wore bad or replaced? It doesnt seen right that the hopper cross augers should have wore out the floor in those few hours, even if the only thing it did was peas. Are the hours accurate? Wilkie sales in Regina sells the liners. Where Abouts are you located?

I'm from south Georgia. The elevator housings look good as I remember. Now that you mention it, I didn't examine the other augers as I usually do. It could have been the grain bin bottoms just rotted out due to negligence. The current owner has had the machine for 5 yrs. The feeder house floor has been replaced. I can see the spot welds from underneath. I asked about these spot welds--he says this is to hold the floor as flat as possible. Is this common for floor replacements? I will have to look in a little more detail on the other augers. I noticed a serious weld on the unloading auger elbow where a four bolt small plate is mounted --on the outside if the auger is pulled in. I didn't examine the plate to see it's function. The man said that weld had been done for some time and they had had no problem since it was done.

Have never seen the poly liners in my area all of them have stainless steel ones. Because of corn seems like the auger is always on. It also is very common to see the elbow cracked on 20 foot augers, I welded mine and seems to be fine since than. The thing to look closely at in my opinion is the chafer frame for cracks, can brake right in two if left to long. Good luck. 986 ont

I had the dealer put poly in the floor of my 9600 before they brought it out. I think if the machine sat outside a lot the water may have rotted some of the floor.

I had a 9650W. By 1700 hours I had replaced all 5 unloading augers, the unload tube, lined under the bin augers with stainless steel, and replaced the loading auger twice. It wasn't rot, as the combine was sheded when not in use.

These machines unload pretty slow unless you speed up the augers. In corn with a grain cart, about 1/3 of the header time was required for unload time. 1700 separator hours is over 500 hours of unload time.

Can you examine the chaffer frame without taking the chaffer out? Exactly where would frame be cracking, one point or multiple points. I'm familiar with case ih--fairly easy to remove chaffers or sieves--seen them break front, middle, and back.
