Question: Pad Replacement

Rah

Hi, I have two model 343 type 2 .The hook and loop pads are not available. Would the pads from the type one work for me?
WJA
The sanding pads for the Porter Cable 343 Type 2 are part number 151281-08
Question: Porter Cable 343 Type 2

898595

Item #66, part # A10943 on your exploded parts diagram is shown with the bearing installed. Does this part (bearing retainer) indeed come with the bearing installed or JUST the retainer?
Thank you
WJA
Hello 898595,

The part in question A10943 bearing retainer, as it shows in the image does come with the bearing installed.

Question: Porter Cable 343 Type 1

Carver

The pad orbits but does not spin. The armature spins just fine and the clutch belt is in place. How to adjust the tension so that the pad also spins?
Looking at the schematic it looks like the cone washers were installed up-side-down. Could this be the problem.
Thanks
WJA
Hello Carver,

Random orbit sanders do not rotate at a high RPM. It is a lot slower action, with a random orbit to eliminate swirl marks on the project you are working on. Let it run the way it is for a while and I think you'll find out it is working just fine.

Question: 343 TYPE I

Caseys

I have both a 333 TYPE II and a 343 TYPE I. My problem is with the retainer in the 343, after a short period of time using the sander, the pad overheats the retainer and the three screws holding the pad come loose. Does anyone know if Porter/Cable or some other aftermarket Man. makes a METAL bearing retainer like the 333 that would fit the 343, I believe the main problem with them being interchangable is the bearing size...any suggestions ?
Hi caseys,
You should replace your bearing retainer and screws. When you install the screws you need to use a loctite 242 on them and this should fix your problem.Hope this helps.Good luck.

Question: Pad

larrypac

Will the pad from the 333 sander fit on the 334k sander? Thanks, Larry
WJA
Hello larrypac,

Yes they will. The only difference is that the 333 was made as a Hook & Loop Pad sander and the 334 was made as a PSA (Adhesive Back ) sander. If your question was referring to the 343. The 333 pad will also fit the 343. The difference is the 333 is a 5 hole H&L pad where the 343 pad is an 8 hole H&L pad.

Hope this helps,
-WJA
