Probably stronger than before it was broken.
No one has mentioned this yet, but I'm guessing from your pictures the reason it happened to you is because you're assembling the parts in the lower case and trying to keep everything aligned while dropping the upper case and crankshaft on top of it. If that's what you're doing, know that it is supposed to be done in the upper case and the lower case dropped on top of the already-aligned parts while the upper case and parts are upside down. Don't worry, the cylinder studs won't be damagedAll disassembled now. I dont know how the dowel alignment got turned like that.
But that's the point, you CAN work on the transmission without touching the top end, you just remove the clutch cover, clutch and oil pump, and the alternator cover, flip the engine upside down and lift the lower case off. Assemble the parts in the upper case so it's easy to get all the alignment pins in place, then put the lower case back on. As for degreeing the cam, I'm assuming you mean setting the cam timing as the stock cam is not adjustable in degrees. The FSM shows you how to set the cam timingHi Mr. Drain. My intention was to inspect the transmission without disassembling the top end. I will begin the assembly tonight as you have suggested. I was asking cam timing questions ahead of time hoping someone with a little more experience would offer me some advice before I jump into that.
Nice internals in your motor! What is the story with the camchain tensioner setup, it looks really interesting. Where can they be sourced. The pistons look interesting too.Hi Yender. It does make for a bad day. That suggestion does seem to be the best fix. I wish that I had a tig welder. Only mig. I have seen those repaired but I'm going to change the upper engine case. I have a couple spares. I think the spring-loaded slide was the culprit for the shifting problem but I was hoping to spot the smoking gulln that caused the metal flakes in the oil. This far I'm not seeing anything that looks abnormal.
Nice.......and with the slotted cam gear you can play around with the cam timing.Hi Gazzweld. The tensioner is a KA slipper. I don't know that very many are being used any more. They take a special cam chain , stock chain is not compatible. I think they are available but not sure where. Maybe Henning has them. . There are probably other ones available too. Ive seen some that look like the stock ones that are bearings instead of the plastic rubber material that disintegrates. View attachment 313873
