  • Worn friction disk

    IMG_20120528_163553.jpgtemp.jpg I came across this friction disk assembly while rebuilding a turret. Never saw one look like this before and wanted your opinions. It's obviously wider (and longer) than what is normal. Is it ok to still use even though it's worn the way it is? My question is what will happen when it wears down enough and there's the inside edge that's keeping the top clutch disk from contacting the friction disk. Better to just install a different facing?

    Personal opinion John, I'd get rid of it. I,ve seen a few of those and never had much luck with them. I like ones like i pulled couple weeks ago at Striketown, original Otis copper w/carbon discs. Cleaned it up, a little oil & grease, new carbon discs and good to go. Only problem is the rivet holes are smaller and you have to grind down edges of carbon discs to fit and that is a PITA. I think all of them are still copper.

      That's the new Brunswick style. I can only see the extended surface producing more friction once it makes contact with the ridge below the surface of the top pulley.

      I've got several in the same state, perhaps slightly more worn... No problem here...but the extra cost of them just isn't worth it IMO.

        i was thinking of junking them myself. i think it'd be smarter anyway than having the inside edge still "new" compared to the rest of the piece and most likely causing issues down the road. i'll talk to w/the HM and see what he'd rather do. overall though, it WOULD be ok to keep it this way, correct?

          You can always redo pads by sanding down unwarned even with the rest
          Easiest way is to lay a sheet of 60 gr paper a flat serves

            John...there are no issues using that style. They are sold by Quality and Murrey International. I have not had any issues with them. If the inner surface does eventually reach any of the other surface of the drive pulley, it will wear at the same rate as the rest of the friction material. It will not cause the disc to slip.

            I prefer these versus the white ones personally...but that is just my take on them.

              I agree with Steve, used the black ones for years and was the best I found.

                ive heard of the black ones being more durable than the white ones. im just wondering about the wear. I see what Steve is saying, that both will wear at the same rate, so it won't really make much of a difference switching it to the white ones.

                  I have heard of issues with the black ones...but I think that was a manufacturing issue years ago. I have not seen an issue with them since. Clean everything up and put it back in and see if anything occurs. I doubt it will but it will make a nice experiment...and I know you are not afraid of trying things like that.

                    well we've never had an issue (as long as I've been there--since September). only bad part is, I can't remember which turret it came from, 25 or 26 hahah. only issue i do know we had was the turret would fail to index at the #1 spot (lane 26). I'll put it all back together and install it and keep an eye on it and keep this up to date as best i can.

                      If it fails to index at the 1...it isn't the clutch facing. Other issues cause that problem.

                        If you have just replaced the short turret belt and have a bind or what seems to be a fail to index at the 1 position the spider release cam can hit the front of the top turrret clutch pulley if the belt is to short

                          i guess i should've made it clearer... as of now we are not having that issue (swapped out turrets since we're rebuilding them anyway). we did have that issue on 26 however. none so far

                            those black one work great when you have a pulley turned down past the wear groove. the wider facing rides on all of the pulley alowing it not to break by being thin. you get extra life out of old pulleys.
