    Back in ‘80 they may have still been solid mount on rear. The two rubber biscuit mounts and steel/cast front gear housing mount for the front were fairly universal between makes. They had Cummins part numbers. It was the actual crossmember/supports in frame that they bolted to that were brand specific because depending on the make and model determined the depth the engine sat in the rails.
     
    Adisiwaya Thanks this.

    The ‘85 BC4 I pulled out of the FL. coe has the same front mount as my ‘74 SC 350 in my ‘67. The BC4 was still solid mount rear in the ‘85 FL. But a two bolt instead of a one like the older ones.

    According to my buddy who used to work for cummins they'd pull the engine and trans as one unit. He said it balanced pretty well by lifting it by the rear lifting eye. Freaks me out thinking of lifting it by a single point but that's what he said

    I'm not familiar with KW, these are the correct mounts for a Pete:
    Front: Atro PL1013-HT
    Rear: Atro PL1018-HT
    You can go to the Atro website and see what KW and Pete part numbers they cross reference to. I have an extra pair of the PL1013 they shipped me by mistake, will make you a deal if you want them

    You'll also need fender washers, 6 total. All are 1/8"/10ga. thick with a 3/4" hole. I can give you Pete part #s if you need them
    2 Front top: 3-3/4"
    4 Rear top: 3-1/8"
    6 Bottom: 2-3/4"

    Could that be swapped from the newer 13 speed (one that's in the blue truck) over to that one? Transmission that is in the blue Kenworth won't split top gears I had a guy re bearing it and and new high low synchro and it never worked right after that.

    Well yesterday was busy and started to storm. K100c cabover cab is no longer attached and in a scraper scrap pile now. He came over with a concrete saw to cut it. Snapchat-350851790.jpg


    Took fuel tanks off both sides last night. And worked on getting the mounts loose. Had the cousin come over to pull the blue Kenworth out of the hole so I can get ready to pull that...

    Oh and the good news my tiger tools finally came so I can drop that driveshaft. Today going to be another busy one
