Parkside (I know!) grinder repair

[Adam_W]

I am hoping someone can help me with this, would be a real shame to throw this out.

I have a parkside performance PWSAP 20-li A1 cordless grinder that I bought for occasional DIY, used it maybe 4 times and used less than 2mm of a cutting disc so barely used, last time I ran it there were some bad sounds and red stuff came out of the vents. It's in like new condition.

Whipped it open and found the rubber piece between the motor and gearbox completely destroyed, don't even know what that part is called. Does anyone know where I can get a replacement part to fix this? Would be a waste and not exactly good value for money if I have to replace the whole tool.

Thanks in advance.

I'm wondering if this is part of the automatic braking mechanism - or just a dirt seal?
Either way, I'd clean out the debris, put it back together and give it a go - if it was mine.

the part meshes the 2 prongs from the motor output to the 2 prongs on the gearbox input, without it they may bash together enough to turn the disc but likely cause more damage

 

[Burnerman]

Of course, that is a possibility.
However, the two aluminium cast parts seem to be flanged, so why not bolt them back together and see if the machine can be rotated by hand?
Sorry but I've never looked for Parkside spares - which doesn't say they aren't available.

Most Parkside stuff has 3 year warranty afaik. Maybe return to store, or contact Owim GMBH?

I think this is older than the warranty, I cant remember when I bought it and I have lost the receipt. Manufacture date was 2017 so I'm assuming its over 5 years ago.

Make a plastic disc, a similar diameter to the drive bosses - it looks as it needs to be around 6mm thick, but measure it. Drill four holes, at 90 degrees spaced, to match the pins.

solent powertool spares seem to do loads off parts for the generic machines so worth a try

they actually mention parkside

If it's older than the three year warranty, parts are also not going to be available.
Your best bet is to just buy a new one, they are cheap enough.

Then use it plenty during the three years (that's 1 year instore, +2 years return to parkside.).

If you can find out the actual maker or importer, you can probably track down an exploded parts diagram, and possibly a source of parts.

I did this with Aldi tools several years ago (it was a big German tools company) but have lost whatever I found out.

That why scanning the Lidl app at the checkout is a handy thing, beside sometimes getting a discount one also gets a digital receipt .

If it were in a motorcycle I'd call it a cush drive rubber.. Plus one for Harry's suggestion of making a new one. Wouldn't even have to be circular; probably easier to cut an exact square. Drill very slightly larger holes than the pins, to give a little play

Consider measuring the thickness you need by oiling the metal bits with the pins then placing a blob of blutack or plasticine on it, sizeable enough that it will be compressed when you temporarily reassemble, then measure the thickness the lump got squashed to

If you don't have any plastic take a look at eg eBay item number 126527729742 - a small sheet of nylon would be a few quid and give plenty of attempts

 

[Adam_W]

Thanks for the replies.

@robinbanks yes as a biker I thought of the cush drive also.

It'll need to be circular as it fits into a recess on top of the fan. I put an stl file together to get a 3d print done but my mates printer has broken. I may have to try and fashion something by hand.

 

[Burnerman]

I'm still unsure what this orange rubber actually does......sure, if the pins on both pieces connect with the rubber item then it is a true cush drive.
The rubber deposits on the drum - is this just dust debris?
Surely the rubber item needs to be as thick as the pins are long?

Yes it appears that it broke up and fell between the casing and the fan, coating that area in a layer of rubber where it melted with the friction, chunks and dust were all over the inside of the casing and had also been expelled from the vent.
