I think my working on the LT is jinxed this year. I had a full 4 hours free this morning so I hit the shop at 7:30 and about 30 minutes into it the power goes out. We are having very high winds (50-60 mph gusts) which I suspect is the root cause.
My shop has windows, but without the overhead LEDs it is hard to see fine stuff. I got my new gold-plated BMW pivot bearings driven in without issue. And they spin as smooth as a babyís behind. I finished the FD installation and filled it with oil and called it a day. Valves are next and I just need more light for that. I am hoping for better luck getting the tensioner pin in this time. Last time I did not get it in correctly and as soon as I removed the first sprocket, the chain and sprocket were pulled into the engine. Fortunately, when I went to install the cams, I was able to easily push down the tensioner and get the pin into place.
I got lucky today and the driveshaft splines slid together like butter. I tried the rag last time and that didnít work so well. So this time I just got the phasing lined up, at least I hope I did as it is nearly impossible to see up inside the swing arm, and let the drive shaft sit on the bottom of the swing arm. I held the FD in place with my scissor platform jack and slowly slide it forward and let the front of the rear driveshaft ride along the bottom of the swing arm. It slide right up and into the front driveshaft like a magic force was guiding it. Usually I spend several minutes futzing with the engagement of those shafts.
The swingarm now swings smooth and free with no drag as with the bushings. I was happy to throw the JL bushings in the hopper. They were pretty gnarly after 50,000 miles. The pin had worn into the bushing on the adjustable pin and brass had transferred to the pin. Not sure the attached pictures will show it, but you can see the shiny brass color on the pin in good light. Unfortunately, with the power out, I had only ambient light.
Definitely glad I took that apart. I donít think I would have made it to Alaska and back given the condition of those pins and bushings. Now, if I can get some power back, I can get the valves wrapped up and move on to what was intended to be my main work this winter, fuel lines, radiator hoses and the normal 24K maintenance stuff.
Here is what good bearings look like:
And here is how an FD should pivot:
