Sitting too long
Missing something
The poor R69S has been sitting much too long. A blanket to keep the dust off is nice, but putting back a missing motor would be much nicer. Now that the house chores are done for a while it's time to get back to this job. A bike needs to be ridden!
Rear of crank
Splash ring
Seal
Seal installation tool
My seal installation tool is a piece of wood with a 1 mm notch. It does the job. The lip of the seal has been prepped with some assembly lube.
New gasket
Ready to install
Installed
Won't come loose
The oil strainer got a new gasket after the remains of the old gasket was cleaned from the rear of the unit.
Oil pan gooped
Gasket, too
Oil pan and gasket
I put some non-hardening goop on the oil pan and gasket. I'd normally use hylomar but as noted earlier, my tube is shot. The goop I used is intended to keep case halves from leaking oil. I've used it for this gasket in the past with good results.
New washers
Hold pan in place
Not too tight
The mounting screws got new wavy washers. Each screw got a dab of non-hardening form-a-gasket before being installed. If I did everything right the oil will stay inside the case.
Air filter gasket
Air filter
Spark plug wire
Two of them
I put the air filter back then used a bit of silicone lube on the grommets for the spark plug wires. That made it easier to pull the wires through the case. At this point the engine is ready to go back into the bike.
Not this high
Install from right side
I put my scissor jack under the bike to support the engine until the motor mounts are in place. The engine goes in from the right side; the petcock is in the way to install from the left. The jack was too high and had to be lowered to allow the top of the engine to fit under the tank. The engine is light and easy to install without the flywheel.
Sidestand is spacer
Rear mount
I adjusted the height of the engine with the jack and was able to slide the front engine mount through the frame, side stand (my stand replaces the engine spacers), and block. The rear took a bit more effort getting everything aligned. It is there until I get the flywheel and clutch installed. Then I'll remove it to make room for the transmission.
Route generator wiring
Top cover installed
I pulled the bike wiring through the channel and installed the top cover. While there I clipped some cable ties and removed the Tiny Tach. It looks like the internal battery is shot. I got more than the 5 years they said it would work. Not sure if I'll replace it.
New gasket
Cover installed
The cover for the tach take-off got a good cleaning and then was installed with a new gasket. The mounting screws got a bit of cleaning with a wire brush, too.
keep dirt out
That's all for today. I put some towels over the cylinder holes and the rear of the crank as well as putting the front cover on the bike to keep dirt out. I think the next steps will be to install the flywheel and clutch, followed by the transmission.
