Ron_B Posted January 2, 2002 Share Posted January 2, 2002 Hi Guys On close inspection of my loader, on my AC4041 i have come across a crack on the lower arm that is attached to the bucket.It looks like someone has tried to weld it on the inside.What i would like to know,is should i have a metal plate put on??? Or maybe i should replace the whole arm. Plus do you think that it could have weakened the other side also.I think it was worked hard at one time.--Ron B PS. It is a SIM Loader.

powermax_paul Posted January 4, 2002 Share Posted January 4, 2002 Hi Doug Thanks for the well needed advice.All i can find on the loader is the name simplicty.The loader is very well built H.Duty.I will get it welded at a local shop.I am still working on the restoration,sanding and painting. Its nice to get a second opinion, when it is all new to me. Thanks again. Ron Link to comment Share on other sites More sharing options...
Byam Posted January 4, 2002 Share Posted January 4, 2002 Ron, Do you know who built the loader and the model number? Mine is a ARC 900 and I know there is at least one other brand that they used. Guess it's immaterial what brand you have regarding the cracks. In the DIY section is a recap of my Loader problems. I believe mine was broken off where the legs extend down to the bucket at one time. It has been "fishplated" on both sides and there are some extra welds on the inside. If you have a crack I highly recommend plating over that area by welding a diamond shaped plate over the crack. Use a plate with enough area to spread out the load. If the other leg is bent downwards you should bend it back and plate over the area where the bend occured. I'm surely no "expert" on this and possibly someone that is more qualified may have a better suggestion. Give me a call if I can be of any help.

Guest Posted January 6, 2002 Share Posted January 6, 2002 Ron, I've made several of this type of repairs. Here's the way I'd repair it sight-unseen. 1. Grind off old repair and gouge out the crack. 2. drill 1/8 to 1/4 in. holes at end of cracks (stops further cracking). 3. Turn heat to 90 with 5/32 in. rod and 110 with 1/8 in. rod and weld crack and holes shut. 4. Turn welder up 20 heat setting for either rod and weld over your fill weld (welding a little wider pattern and watching to "fuse it well at edges". Your done at this point if you don't feel it needs plated. If it does need plated then, 5. Grind weld smooth and plate it welding all the way around the plate.
