Bent flywheel?!

[minnnt]

We've recently been experiencing problems with our tracked 190 chipper. I work for a local authority and for the last four times that we have taken it in for blade changes i have reported that it has stopped self feeding. i.e. just dragging in branches etc without stopping to build the revs back up. (not entirely sure what this is called) but this would cause the chipper to stall and then we would have to undo the shoot and clear all the chippings out before it would restart. This last time after filling an accident form in regarding something that happened because of this fault, the garage department has decided to get the dealers in to diagnose the problem. Our mechanic never fixed the problem even when reported. (probably over 6 or 7 months) The dealer has now said it is a bent flywheel. Would this cause the problem mentioned and what could cause it? The machine is used by around 45 different people, but primarilly by my team and non of us can remember any steel bars etc going through it to inflict such damage.

 

Got a feeling that the management are going to try and nail us for the damage which has been costed at £6,000. Just looking for a few facts and ammunition to back me and my team up. They can't really pin it down to a select few as like i said the whole department has used it at some time.

 

Thanks alot. David.

. i.e. just dragging in branches etc without stopping to build the revs back up. sounds like the anti stress box not working. £6000 for replacing the flywheel sounds excessive.

does sound like metal has gone in. but u should have had a set of wasted blades somewhere when this happened. maybe another squad has covered their tracks by changing blades and keeping quiet.

No one else touches blades other than the mechanic. Thanks for info on 'stress box'

some body would have had to put some seriues metal work thru that chipper to warp the fly wheel,£6k some ones having you over on that 1,

[RobRainford]

does the 6000 include them chewing it off instead of using tools?

 

for that cost get a new chipper!

 

for it to warp it would have needed some serious heat and some serious force, they arent made of paper!

This is our argument, but the mechanic is a a-hole and the management listen to everything he says.... we definitely haven't put anything like that through it, can't speak for the other teams though.

Warped Flywheel would make the machine gyrate like mental.

The last 190 tracked flywheel I see the price for was £1600 that included the stub-shaft etc it runs on, also taking an old flywheel off and fitting a new TW190 flywheel & stub-shaft is not exactly a slow job and should be easily done in under a day, as ware the £6k price tag if from I don’t know but they (LA) are either lying about the cost or the LA is being stiffed on the parts and labour cost

Thanks for all the info. Nothing has been said yet, I guess its on its way though. There could be other items damaged too, but no one has said that yet. Just waiting for some excuse from the mechanic as to why it wasn't fixed when first reported, maybe then it could have stopped any further damage. The anti stress box hasn't been working since last winter at least. I have reported it at least 4 times and nothing has been done. Unsure as to whether or not the other teams have reported it. Thanks for the info on pricing of the flywheel and time scale for doing it. It won't be fitted by the dealers, the mechanic will be doing it and then they charge the parks department for the parts and labour etc.

 

Cheers!!

Point your manager in the direction of arbtalk, the guys on here are wiser in the ways of chippers than a council mechanic. Of that i have no doubt!
