reb87 Posted April 2 Share Posted April 2 Does anybody have a part number or picture of the cab exhaust hangers for a Mack LJ? Mine was mounted to the winch frame which I have removed. I see factory threaded bolt holes but need to fabricate or buy some mounts. Probably the same for all L cabs?

reb87 Posted April 2 Author Share Posted April 2 I modified one off of another truck to temporarily drive it, anybody have a part number for the original? I’d welcome any pics of the factory hanger arrangement. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75362-mack-lj-exhaust-hanger/#findComment-572677 Share on other sites More sharing options...

That's the early style with three clamps bolted to the cab. Clamp is 4 ME 2258-P1. I believe it's the same for all the early L series cab mounted mufflers. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75362-mack-lj-exhaust-hanger/#findComment-572715 Share on other sites More sharing options...
mattb73lt Posted April 4 Share Posted April 4 I deleted the brackets on my B73 and put the exhaust on a late model support arm. The later L cabs only seem to have had two brackets, one near the top below the louvers. The lower one was mounted to the lower internal cab frame in the corner. There were spacers inside the lower mount to make up the gap between the skin and the frame. I saved my two brackets, but they were pretty rusty and had been modified by previous owners. Let me see if I can locate them. Here's a picture on the corner of the cab with the skin removed. The upper bracket is still in place on mine. The two lower, short brackets below are for the grab handle. Then the lower frame of the cab. Second picture is after I painted it, but before I put two polished stainless bolts in the threaded holes as place holders. I left the bracket as it stiffens the area and if someone in the future wanted to add the bracket back. I've seen the schematic you posted before. The four bracket arrangement may have been for the heavier LJ-X versions like yours. I don't think regular LJ's had that type of arrangement. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75362-mack-lj-exhaust-hanger/#findComment-572825 Share on other sites More sharing options...
mattb73lt Posted April 4 Share Posted April 4 I found the brackets. The 90* base strap is the original part. The round clamps were added when someone added a vertical muffler to the truck from the original staight stack. The lower bracket has an added 90* bracket that bolted under neath the cab corner. 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75362-mack-lj-exhaust-hanger/#findComment-572878 Share on other sites More sharing options...
