Re-build Set-up.

Preparation.

Maybe santa will stop by tomorrow and help me finish up.

Cam chain went swimming earlier.

Ready for cylinders.

 If there is an arrow on the piston, point it toward the exhaust.

If there is IN stamped on it, well then that faces the intake.

 ９０パーセント準備だな。

Perfect song for an X-mas eve alone.

Honda CB160 Piston Ring Installation.

I have enough bandanas for now.

Back to motorcycles.

Piston ring install.

I wasn't sure if I was going to have to adjust the rings so.....

Push the ring in.

 Measure the gap.

(CB160= .15mm~.8mm)

My new rings were pre-gapped at about .18mm.

Rings must be installed with the manufacturers marks facing up.

Order of rings.

The oil ring very obviously belongs on the bottom. 

Piston rings marked with an "R" or a "T" are the top ring.

Ones marked with an "R2" or "IT" go in the second position.

Point of caution:

The packing grease from these 40+ year old rings had become tacky which prohibited movement once installed.

They were removed, cleaned, lubed, and re-installed.

What I did on top of what I should have been doing.

It's finals season.

One of those nights.

Crankshaft swap. Movement 1: Extraction.

Moving forward.

Puzzles in Puzzles.

 Extraction complete.

 Safety first.

 Pistons eating valves.

 What are you looking at?  

You're next.

Feeling capable of.

Top to bottom.

Period correct.

Gonna get chopped.

Moyou approved.

This was the piston with the seized clip in the cb160 engine I was trying to use...

Damaged beyond repair = Crank swap.

+Bottom end rebuild.

+New oil seals.

What else should I do while I'm down there.....

Take your pick.

Left engine could easily be a runner.

I got the right engine from a guy after a bit of valve failure blew a piston.

Left cylinder.....

....was leaking oil into the combustion chamber.

Valves looked good.

 Workspace. 

 Hideaway.

 The culprit.

Piston pin seizure. (?)

...and of course I can't get it out.

Zen.

Saturday Sunshine Garage Day

Finally got these in the mail.

1+ pistons for the CB160.

Piston helper tool man.

Cleaned up the repaired CL160 exhaust.

CL160 tank mounted, petcock gaskets ordered, seat re-worked.

Moyou aproved.

Gas drained, baby dream stripped down...

New petcock.  

Letting the gasket compound cure.

Gas tomorrow or Monday.

 Fairing on the C2.

Still needs adjustment.

Not yet Moyou approved.

She said it stinks of Harley.
