  • PC400 bucket

    Fixing a 66" bucket. New edge, shanks, & a few wear bars on top of the old ones. I fixed this bucket about a year ago when they snapped the cutting edge & up through the sides. Pulled it all back with chains & binders & welded it up cause they didn't want to spring for any new parts then. The cutting edge held up but was worn then & worse now. They snapped a corner shank off now while prying & the mechanic welded it together for short term.

    First pics are of the old repair. I don't actually have any finished ones of the old repair.

    This time they wanted me to just replace the shanks & build up the scallops in the edge. I talked them into a new edge also. So here is progress pics. Probably finish on Monday. Old edge out, & new edge & corner shanks in.

    Forgot to mention I'm changing the shanks to Cat style. The new edge is 2" x 14" x 70". Welding with Tri-mark 777 & ESAB 7100 ultra.

    Edge, shanks, teeth & locks was $2783.00.

      Pretty sure you can buy that edge with the inner shanks already installed.I believe there molded into the edge.Cat and Esco if my memory is right,Just saves some time welding them inners on.Only have to do corners after lips in.For future if you do this another time.Btw looks good.

            Admweld, Dont you know what kind of site this is.

            I heard the molded one break off really easy and are junk so you always want to buy them separate and have us WELDERS WELD THEM ON .

            Theres nothing I like better than cutting into an old bucket, putting wear bars in, A little line boring here and there.

              Finished pics. Edge & shanks are on. Added some wear bar sections on top of the worn ones. Added a couple plates behind the edge on the inside as it's wearing thin from the inside since it has 2 layers of bar on the outside.

                Geez ooo peeets, That thing is never going to wear out.

                Nice job MMW

                Between you making things that never wear out and admweld telling people about moe boards with molded in shanks.

                I'm never going to have anything to weld.

                  I've never seen a pre molded edge. While I was working on this the local Cat dealer rep showed up & told me he can get the edges with the center shanks pre-welded on. Didn't ask the price as I'm sure it's expensive from Cat.

                  Quote from Cat - 6 shanks (adapters) only for this bucket = $1800

                  My guy - 6 aftermarket shanks, teeth, pins & locks = $1633.00

                  I've never had a problem with the aftermarket shanks or teeth.

                    Yup, When it comes to cat parts hold on to your a$$

                    After market is the way to go.

                    On the flip side the cat parts may last a little longer ( Higher quality steel ) but not that much longer to justify the inflated price.

                      Why the 2 different wires? I looked them up and seem interchangeable. What gas did you use w/ them?
                      Very interesting thread! Thanx for posting.

                        Explanation of equipment & wires. Short story made long.

                        This construction company rented half of their building out to the fab shop that I worked for from 86 to 09. When the fab shop went out of business the construction company basically bought the equipment from my bay. 3 ton gantry crane, Delta weld 452, 22a feeder, old Lincoln Idealarc 300/300 stick machine & an ESAB plasma. When I do work for them in their shop it's like coming home for me, just that I'm on the other side of the wall.

                        So the wire question -- They had about 30# of TriMark 777 on the feeder when I got there. I used that up & then stuck on a spool of ESAB 7100 ultra which is what I normally use. The wires run very similar, it's just that we use two different suppliers who stock different wires. As far as gas, I used co2 until their bottle ran out & then had to use 75/25 which I had with me until they replaced it the next day. I prefer co2 with these two wires but 75/25 is acceptable.

                          When the customer buys the stuff and dumps it at your shop you don,t have much choice at the point.Thats how i had seen that style before.And yes i will agree with the aftermarket supp
                          lies on cost.I usually use hensley from my supplier around here.

                            a couple more questions...

                            The new edge you put on, did you preheat and/or post-heat that before/after welding on it? Was it an AR steel or something else?

                            The shank welds were hard faced or left as is? If not hardfaced it seems they would wear pretty fast.

                              No preheat or postheat. Don't know the exact composition of the steel. When I order these I just tell my supplier I need a cutting edge for xxx & here are the dimensions. If it had been in freezing temps I would have preheated.

                              No hard facing on the shanks. The way the shanks are cast there are large bevels on the sides & back. I put three passes on them just bring them out flush. The shanks are also tapered front to back which helps with wear. Once the tooth is on it is larger than the shank so that helps shield it also.

                              Here is a link to a pic of a shank. You can clearly see the bevel where the weld goes. http://www.ebay.com/itm/ESCO-BUCKET-...744264&vxp=mtr
