Rejected Warranty Claim Advice

Tarw Coch · Nov 8, 2018

To my surprise I have just had a warranty claim rejected on my straw chopper. The sprocket where the shear pin fits has worn, the shear pin fits in what I presume is a hardened bush with a knurled outer edge which fits into the sprocket. The sprocket had worn so that the hole where the bush fits in had become elongated so in the end the bush would fall out when the shear pin broke.
The dealer/manufacturer is now claiming this is a wearing part so not covered by warranty which doesn’t sound right to me, surely the whole point of fitting the bush is so the sprocket doesn’t wear.

Any advice on how to proceed would be welcome, my feeling is that the dealer/manufacturer aren’t honouring a genuine warranty claim. Also, has anyone else encountered this problem on their straw chopper, as if it is a wearing part I would expect others to have encountered this problem on older machines.

Who made it ?

Need more details.
What age and work done?

Surely a sprocket will wear? Sorry if I’ve read this wrong?

Not enough detail. How old is it? Is it even in warranty?

Tarw Coch · Nov 8, 2018

Machine comes with 2 year warranty, second year parts only, it would have been about 20 months old at the time of repair.
Usage wise using 2/3 bales a day through winter months with occasional use bedding calves in summer, I’m sure there are plenty of machines doing far more.

I understand that the teeth on a sprocket do wear but I wouldn’t expect a hole to wear in the center where the shear pin fits, my previous machine of a different make did 15 years without the sprocket wearing out and I have never seen or heard of anything similar happening before.

In my experience holes wear because the shear bolt hasn't been correctly tightened

How many times has the shear bolt broken?

+1

That's exactly what I thought.

Not sure, we have only had one pack of shear pins from the dealer and haven’t used them all. I’m sure the shearpin has always been tightened up tight and are fitted with nyloc nuts. It’s not the hole the shearpin goes through that has worn, the shearpin fits in what I presume is a hardened bush that fits in the sprocket, it’s the sprocket that has worn around this bush.

I had a similar issue on my lucas. Hardened bushes were breaking up when the bolt broke, which was unnecessarily often. The inner flange was able to float on its keyway, opening up small gap between the shearing surfaces. After messing about with washers with some success, I slackened the grubscrews on the bearing and knocked the shaft onto the gearbox a few mill. No probs in 3 years hard work since.

I did get the impression that this lucas was a bit soft compared to the one before - chain started breaking rollers within a week, but dealer sorted all issues out of their stores with no suggestion of me paying. Just silly teething issues, nothing long term.

Different make to mine and in my case it was the sprocket rather than the bush that was the problem, the bush looked fine.

How much is the sprocket?

tr250 · Nov 8, 2018

Ours did the same last year but it's 10 years old doing 15+ bales a day in winter. In our case it was the plastic bush that fits between sprocket and shaft had worn so the shearbolt always worked loose and wore a elongated hole in the sprocket as said here. That was a teagle

Not sure off hand but probably not enough to spend a lot fighting the case.

Mine has only done a few hundred bales though, not a few thousand.

Is it a teagle if so Tom Teagle regularly posts on here to sort his machines personally

I used a red and yellow machine for a long time. Moderate use I would say. Only fairly dry straw, never saw silage, haylage or a rotten or even half damp fousty bale in it's life. I wouldn't buy one myself. I think you can do better.

Was it made over the water and is it green
