RH Crankcase clutch adjuster grease/clutch rod seal '66 CB77

Post by Tropicalpunchai » Tue Jun 06, 2017 6:51 pm

Hi all, I just purchased a 1966 CB77. and this is my first time working on a bike other than oil changes.
The guy who sold it to me gave me a new clutch cable.
So, I wanted to replace the clutch cable. When I opened the RH Crankcase, it was covered with oil and/or grease.
So, I was searching on this Forum to find out what grease to use...
Instead I found out many people have issues with clutch rod seal popping out???

Question 1, Which one is the clutch rod seal? the one behind sprocket? mine does not look like it popped out... can someone confirm?
how would I know if this mess was caused by the oil leak? i have already cleaned it all...

Question 2, so... what grease do I need and where do I apply? just inside the clutch adjuster ?
When I tool the RH crankcase cover off, my initial thought was that grease needed for the clutch adjuster and kick starter gear... Why can't i find the information about grease?

Thanks in advance, Ai[/img][/img]

the cover side of the RH crankcase. I am thinking I need to apply grease in the area it has different color grease/oil and the gears.

Bearing in mind I know bugger all Punchy. I put a new cable on mine a few weeks ago as the action was so heavy and for your interest it was almost as bad untill I pumped oil into it and re-routed outside the tank.
Like you I found lots of mucky grease in the case which had come from over zealous use of the grease gun on the pivot and kickstart spindle nipples.
Can't come from the engine, there's none in it !
Two things to watch for - the 5/16" end thrust ball. It looked safe stuck up inside but it wasn't. It escaped and the fairies carried it off before I noticed. Grrrhh. The other thing, the two gears have markings to line the teeth up. Very faint but they are there.
Now can you tell me where the breather pipe from r/h cylinder goes. Have just found it dangling in space !
Best of Luck. Rob.

Down and to the right side of the left carb should be a sort of loop for the tube to be held by then through a slot cut in the front edge and to the left of center in the valley cover then under the cover fastener to the right and if possible (not all will) through the hole behind the drive sprocket. ...............lm

Thanks L.M. even more mystified now though !
Thought I had sorted it when I found that both cylinders had a nipple in them which appears to lead up into the inlet tracts near the valves.
Thinking this was a balance pipe between the two inlet tracts I have coupled them up.
Not road tested yet but she fired up ok. So where does that leave me.
I did wonder if they had a dual function. For attaching a manometer to balance the carbs and to smooth the inlet pulses when running but what do I know.
Not much.

As you look yo will find 2 of those.
HONDA designed this breather? system to go to a plastic "Y" then a single to go to the front of the right side air cleaner. ...............lm
