I got back from the Rally all well with everything except my running shoes, as one fell off somewhere between Pennsylvania and New York State. At the US, Canada boarder I discovered one was missing and I just tossed the other in the trash. No good keeping one shoe. I tied them to the webbing but not good enough. I have some shots on the odometer at the start and at the end of the trail when I parked it in my garage after the return. 1716 miles round trip. I didn’t get the long distance award, as I was less +150 miles from the winner, so good for him. As you see, I don’t bring my bike to show and shine off of a trailer to get a trophy. I like to ride it.

Now to The Bent shifter Award. Pete Turner should have got this one this year but someone who had a Portuguese lay shaft bearing go south, got it.
The event… The Rally picnic ride to Peaks of the Otter on Wednesday was the route. Riding as our own group Canuk’s ONO and New York’s NYNOA decided to hold back from the crowd to drive hard and fast. Somewhere past the 61-mile marker on the Blue Ridge southbound, Pete lost oil pressure, which he recorded on a camera and he tapped on the oil gauge to see if it was stuck. 30 seconds later his Combat engine is not making good sounds. De-clutching and trying to down shift only smoked his tire as the engine was locked up. I was directly behind him. Nothing would move. His Combat was dead to him. Once we got the bike in a safe area, Pete stayed with the bike while Richard and I road back to the camp to get the truck. An hour later we had it strapped down and headed back to the campsite. We placed it in the pavilion in our area campsite and drank some beer meditating. Dynodave came by and we talked an suggested we pop the timing cover tomorrow and have a look see. As a group we were training our thought on the oil pump.
The next day we opened it up and sure enough the oil pump shaft was bent and the worm gear was missing teeth. Disassembly of the oil pump we found hard metal bits embedded in the spur gears. What was the cause? I was thinking as well as some others that one of the combats thrust washer tab on the cam or the hardened cam lifter pads broke away. No one was injured so thanks to that but Pete’s bike needs attention back at a shop.
Today I popped by Pete’s home with some of my Norton tools and we did an exploratory. Here is what we found:
Cylinder is toast and one con rod piston toast.
Spun bearing on Timing side.
Combat timing side. Norton had some bean counters changing the 72 crank case halves Don’t you like the Bean counters. Look at all the beans.
Snapped con rod bolt and what’s left of the shells and connecting rod cap.
My suspect thrust washer is still there so not this one.
The builder chose this cam bush for the inside.
The remains of the timing side connecting rod and piston. Toast.
Drive side con rod ok and shells were ok.
Teeth busted on the Tach drive.
Combat cam has busted teeth on the gear but lobs are ok. Toast.
Lifter Pads look Ok.
Cleaned up cam but too bad for the teeth on the gear.
Here is my suspicion to the cause.
Pete’s now looking for an 850 engine complete preferably 74.
Happy Trails,
Lets hear it :mrgreen:
Cheers,
Thomas
