I don't think I'm reading this manual right, but my bottom slats are 1/8" off the floor but the chain is making suh a racket I don't think that it should be that way? It seems somewhat loose and if I tighten it to get it to the point of not slapping it rides roughly 1/2" off the floor, is this correct?

1/8" is about right. Do you have the rollers that help hold the top of the chain up a little? They make a difference on how much noise you get. There is also a poly guide kit that goes on the top rails where the chain returns. I think the rollers do a better job. I would think 1/2" is going to be way to tight. Are you hearing the noise in the cut or when the machine is empty? Are the sprockets in good shape or are they getting where the teeth are hooked? Any recent work done on the feeder? Seems if memory serves me correctly that you can get the sprockets out of time to each other but I may be thinking of something else too? Can probably send you a picture of the rollers if your interested.

Yep 1/8" is plenty. Less would be better. Just off the floor is about right.

They will make a lot of noise, and get worse as the sprocket valleys wear lower into the sprocket and the teeth cup. Then the chain rubs the stripper plates and makes more noise yet.

Make sure your chain is in the right direction and that the sprocket shaft bearings are in good shape.

If you have a stone retarder drum, make sure the bearing plates are not cracked out and that the sprocket grooves are not worn so far that the bars ride on the drum.

The chain was replaced not to long ago, I take it you get those rollers from a dealer? It's just slapping the guide up top, haven't started harvesting yet so it's just running empty. I just hate hearing a noise like that is all lol.

I believe the bearings should be good and the bars aren't close to rubbing on the drum.

Also notice the electric reverser doesn't always want to engage, can I somehow put a hydraulic reverser on?

I dont know anything about the hydraulic reverser as I dont use reversers, but there has been a lot of mentions of them on this site and on agtalk over the past years. But the electric is known for staying stuck engaged and can make a heck of a noise and get hot enough to start fires.

I think page 34 in this catalog has the feeder silencer kit you are looking for. They are definitely worth every penny. I installed one on my 1680 many years ago, then had to make an emergency repair in the field requiring that I buy a new chain. Dealer only had the 3 strand, so I went ahead and "upgraded" (which is actually a down grade) to the 3 strand. Had to run a couple days without the silencer. WOW was that nerve racking as I kept thinking something was going to explode. Then got the 3 wheel silencer and all was good again. This season bought a second 1690. It has the 2 strand chain and no silencer. It is quite noisy even with new components. I will install a silencer kit in it this winter for sure.

Yeah that's what I'm worried about, we have pretty heavy crops so there is a few times I will need it, don't seem like it works that well.

Yeah I know what you mean lol, I hate hearing noises like that, always get me paranoid

How long did it take you to install? Pretty big job or not overly? Just wonderin if I can squeeze it in before harvest

I bought mine from the case dealer and it came with a couple sheet metal disposable drill jigs that you line up on the feederhouse and mark for drilling. I dont recall if it is a 5/8" or 3/4" hole, but just one hole on each side.

Then just follow the directions and you'll have it installed in no time.
