November 24, 2025 Originally, I wasn't going to document this as I've documented engine/gearbox rebuilds before. But the owner's story tells me that this one might be interesting. Especially since this will be the highest mileage Norton I've ever worked on.
As a part of his introduction, the owner said: "I recently acquired my old college roommate's 72 Norton 750 Interstate with a Combat Engine. It has over 78K miles on it and supposedly has never been opened up except to replace a cracked piston skirt early on in its life. He was stationed in Germany in the 70s and bought and had shipped back this bike from England so he is the original owner. I have known him for over 50 years and his recent bad health has had him put the bike up in 2021 until this August when he gave me the bike. I have gotten it running but there is knocking noise coming from the cylinder head I believe and it pops out of first gear. So I would like to get the engine and transmission rebuilt."
He is planned to bring me the engine and gearbox this weekend. I'm hard at work on
Combat 5
and two more heads and
MKIII Rebuild
but I'm always stuck waiting for parts so this should fit in just fine. The goal it for him to have it back to ride in the spring. Of course, that will be much easier if I don't do any hospital stays!
Today, I looked around for a clear flat spot to put his engine on - found none - so I spent a lot of time straightening, putting away, and cleaning and now there's a place!
This will be it's home at least while taking it apart and figuring out what it needs. Then it can go in bins until ready to be assembled and the gearbox can be worked on here. I considered building another of my
mobile work tables
as it would be more comfortable than working at a Workmate but I need to get some of these projects done!
BTW, the black thing is a heavy duty "Lazy Susan" and the engine stand is a modified version of the stand Andover Norton makes. I have sent them the plans and hopefully once they've sold their current stock they will start making my improved version. With mine, you can get at the bottom bolts and screws and you can get to the sump plug(s). Also, when I ship engines, I mount them in this stand, screw the stand down to wood and that becomes the bottom of the crate - of course, insisting that the receiver take the stand apart and send it back.
