Good day, I have a 72 all crop combine. I replaced the rubber shelling plate and rubber concaves last year, but now I'm trying to decide whether it is time to replace the cylinder bars due to rubber wear. Wheat comes out pretty clean, but I found I was cracking white beans a lot last year. I guess the rubber on the bars should be square and flush with the metal face of the angle iron it is attached to? Also, I know about the terrific all crop parts guy in PA, but I'm wondering if anyone rebuilds the bars (ie: replaces the rubber on the original bars). I doubt this, but thought I'd ask just in case. Look forward to hearing from anyone with experience in this area regards

| Slow down cyl speed as recomended. On our 60 we changed bars when about one eight of metal was showing on wheat .On oates you could go a little onger |

I'm not familiar with the All Crop cylinder bars, but I have some NOS rubber strips that look like they could be for that purpose. How is the rubber attached? ------------- ALLIS EXPRESS! This year: |

| Good question. I am assuming glued somehow, but I need to go out and take a close look (combine kind of sandwiched back in the corner of the barn for winter...so not sure how easy it is to get into the thing for a proper look...but I'll try). |

Update to my original post: I am trying to get a good photo of the tip of cylinder bar as it passes by concave bar (as seen through inspection window on side of machine). |

Welcome to the forum! In regards to your beans, I've always been told speed cracks, clearance crushes. I'd say you're running too fast, as your bar looks pretty good yet to me. On small hard grains, you don't even need the rubber (hence the reason all other brands of combines had steel rasp bars). All 3 of my All-Crops have the rubber worn down to practically nothing (some bars have the rubber totally gone), and do excellent jobs in wheat and sorghum, but I would imagine having good rubber would be important for white beans, but then again, I've never combined any. You are correct when you say the rubber should be square with the end of the angle iron (at least, when new). The rubber was originally vulcanized (to make it wear longer) and on the first year or two of All-Crop production they were riveted to the angle iron, with subsequent years using what I guess was a special adhesive. I've heard you can use automotive adhesive to glue new rubber on, but I've never tried. There is a place out of Wisconsin that sells new bars but I can't recall their name. Your replaced concave bar looks good. They are somewhat easier to replace, being as they are just clamped down.

| the rubber on Dad's combine was either molded or glued to the cyl. I do remember seeing them sometimes where the rubber was almost worn off. we did replace the bars once and boy...was that a $%@&*#%@ job! |

| Replaced bars several times on a 60. Put sacks on straw rack and crawl in.Had nothing but plain wrenches to work with.Dad was glad he had a teenager and a good shade tree. |

even if it seems like more work....you can remove the top sheet metal first (take off the reclaim tube, drill out rivets etc) and work from above....you can see other flaws and fix whats needed...then replace the rivets with 1/4 bolts and button things up...Mark |

| Marv on here has a thread where he tried to replace the rubber. If I remember right, it didn't work very good. |
