Timing chain replace

cleg · Post by **cleg** » Sun May 13, 2012 8:06 am

I just acquired another CB77 (blue 1966) on Craigslist that I could not do without, with that said the timing chain is noisy. I removed the tensioner and the center rib has chunks out of it, I believe from being too tight. I took the tensioner from my other 66 and installed it and adjusted tension. The chain is very noisy still so I am thinking that a new chain is in order. How difficult a task is it to replace? Anyone have a step by step? Thank you.

I would also be concerned about the other neoprene wheel in the middle of the engine.
Ya can use the old chain to loop in a new one. .........lm

LM is correct about those idler wheels. I have broken two and the result was a series of bent and broken parts in both cases.

If you are not familiar with doing work on these engines such as cam chain replacement and such, I would first start by searching this forum for help, us the "search all terms" button, it will lead to a huge gallery of posts. Also, I'd buy bill silvers book, you can get it by contacting him through his website just google search "Bill Silver" "mr.honda".

@teazer,

How did those wheels brake on you ? I replaced mine with near mint looking ones from a lightly used spare engine, ( no cracks or chips) do you suggest periodically looking them over for wear?

P.s. lm, when will you put out the "LOUD MOUSE" Honda 305 manual ??? :)

Is the part # for the lower cam chain wheel 14611-250-310? As far as the the tensioner, are there early and late versions?

It's been a while since the post, but between work an other issues I may someday get this done.

That is the guide in the center of the engine.
The tensioner is at the rear of the cylinder and came in 2 sizes.
The engine number will give the correct one needed in the parts book. ................lm
