Vicon Fertiliser Spreader PS302 Model

[EDAF]

Recently purchased a vicon spreader PS302 which needs some attention. I have removed the aluminium housing from the flywheel and replaced the bearing which was in poor condition. I continue to have a problem when I engage the pto shaft, the spreader runs ok at low rpms but when I increase the speed the spreader starts to vibrate and gets progressively worse. I am wondering what the problem is ? (The spreader is empty when I am testing it)
The bearings on the back end of the wishbone and the centre spreader shaft seem to be in good condition and no play can be detected on them. However the rubber coupling fitted to the spreader flywheel shaft has worn down and is off centre and the covering plate which is part of the shaft is also off to one side alot. Could this be my problem or is there something else that I should be examining ?
Another problem is the bottom edge of the plate which allows the manure out of the hopper is cutting into the plastic basin underneath and has cut completely through a third of the circumstance of the basin. The plastic cover which the plate sits on (is fitted to) may have spread from wear and tear causing this to happen. The plate itself appears to be in good condition and sitting properly on the top of the plastic cover. Any solution to this problem, maybe grind down the edge of the plate with a grinder so it does not touch the basin ?

Thanks

Not sure on which model but if you look at the back of the flywheel thing there is a a rubber thing at the back of the main shaft? had to change one on ours.

Now Then..
The shaft through the middle of the flywheel passes through a plastic bush. Corrosion can build up, the shaft not move relative to the flywheel causing vibration. Take it all to pieces, clean / replace parts as required.
The painted spreader plate can corrode pushing the stainless plate down therfore cutting into the cup below. Again, you'll have to take it to pieces and replace whatever is necessary..

Thanks guys, I have started to disassemble the shaft through the flywheel, can I change the rubber bushing on the shaft without removing the wishbone and flywheel itself?
I think the shaft is stuck firm so may have no option but remove the lot.

Has anyone removed the shaft through the flywheel on the vicon spreader 302 or 303 model, what needs to be removed to get the shaft out. I have the pto shaft off and the pin, do I need to remove the wishbone and will that create enough clearance or does the centre shaft need to come out as well.

Pull centre shaft up with wishbone intact, circlip holding it in, easier than it looks if it's been kept greased.

 

[EDAF]

There is a black rubber cap on the bottom end of the centre shaft, does this unscrew anti-clockwise and then I have view of the circlip I take it. Hopefully there is grease in there and the shaft pulls up out of the bearings. Am I likely to dislodge any bits when pulling the shaft that could be difficult to put back again.

Have you checked the wishbone bearings as well. They make it vibrate and rattle if not super tight.

 

[EDAF]

The wishbone bearings seem to be tight atleast when you shake the spout by hand. The shaft through the flywheel is corroded solid so I need to get this freed wich may then lead me on to the bearings if the vibration continues.

 

[v8willy]

The cap is a push fit on mine, pulled out with a pair of pliers.

A few bolts pulls the whole unit out of the frame, makes life easier & you have gravity helping then too, maybe you have it out already? I would put the full set of bearings in for all they cost, job looks worse than it actually is too.

I have a parts diagram out in the workshop I'll take a photo of it if I mind & post it up for you.

Thanks for the help, I haven't removed the frame but it was something I was thinking about alright, the bolts look to be corroded but it's not a big job to replace them anyway. I have tried to free the flywheel shaft by spraying WD40 from the back end a number of time and leaving it overnite but no luck. The next step is to start taking it all apart and I will replace the bearings as you have rightly pointed out. Great if you can post the diagram as it would guide me in the right direction.

No idea of how big the parts are you are trying to separate. If you can soak them in bucket/tub of diesel overnight. it will penetrate way further than WD40

good website too. may be of some help

I think my best bet is to start disassembling the spreader as the shaft is not budging from the flywheel despite by best efforts.Thanks for the link I will check it out.

Got my spreader fixed, removed the shaft through the flywheel , stuck solid with rust but managed to get it out without damaging the head of the shaft. The plastic bushing that is fitted to the shaft was in pieces, cleaned off all the rust and fitted a new plastic bushing, also replaced the bearings on the centre shaft before putting it all back together.
I removed the plastic basin which is held in position with a bolt either side of the wishbone, there was a considerable buildup of manure underneath and the basin was not seated properly which was causing the edge of the plate overhead to make contact. Again cleaned it all up and seated the basin properly and used silicone to seal all around to prevent manure getting down again. I also replaced the bearing on the aluminium adjuster wheel mounted on the flywheel, got a small bushing fabricated to take up the slack on the front end of the wishbone. Very pleased with end result, running very smooth again, thanks for all the good advice.
