Hi All-

Since I picked this one up not running, no history, and haven't been able to get it going, I thought I should l take it down to bare bones. As you can see, the screw boss, screw head and casing have suffered and need replacement parts along with a broken right chain guide etc.

My questions is- are their any new parts available and from who (in North America - preferably Canada). Secondly, if I go with the stock parts, am I replacing something that broke with something that is likely to break again as this was a weak point of the 500's from the factory? Are there aftermarket replacements that are better?

Thanks!

The damaged bolt is very common. I'd leave it alone. Replacement blades can be found at David Silvers Spares. They are repo's and have a mixed history of failure. I have some in my son's bike and have had no issues. But others have. I may have put them in a friend's bike but dont recall for sure

Thanks nolimitz- need the chain as well - will take a look athwart they have.

BTW: The piece that is broken is the camchain tensioner. The part that pushes the camchain tensioner against the chain is the camchain tensioner adjuster.

Edit: see post #14 (thanks Randall)

I stand corrected- found one on Kijiji for $50- seems like high $$?

It is high for a used one but not too bad if it is a new original Honda one.

Says "new old stock", not a lot of options!

 

[Sidecar Bob]

I'd grab it if it is in a sealed Honda bag.

After some of the reports of the ones from Silver's failing there aren't many options.

Since you will have the engine apart, check the internal condition of the oil pump. Steel from the ground away bolt head can damage the oil pump.

I just received my manual cam chain tensioner from DSS today I did not realize they were problematic. I thought just the autos were a problem.

If one type is bad I wouldn't trust the other the from the same supplier.

The adjuster pushes the adjuster?

They are different parts.
Timzim, can you post a photo? I'm curious to compare it to old stock.

 

[Sidecar Bob]

The camchain tensioner adjuster pushes against the camchain tensioner against the chain. If you check you'll see that's what it says (now ;-)

Yeah, they are different parts but they have the same basic construction so I still wouldn't trust them.

 

[reclinedrelic]

When the bolt sticking through the rear cover is loosened the cam chain tension is adjusted. Much simpler and less confusing to simply call the part which moves after the bollt is loosened the tension adjuster. The tension adjuster causes the tensioner to move thus adjusting the cam chain tension.

Thanks Mike- definitely cleaning out everything, lots of bits in the bottom of the engine case.

 

[timzim]

I will try and post a picture tonight, but it looks just like the one on their website. "From a manufacturer with a proven record" I really don't want to be cleaning bits from my cases .

Don't forget to replace the o-ring on tensioner bolt..

 

[Sidecar Bob]

Yes. We've had a few reports over the years of people who decided the original o-ring on the adjuster bolt looked good enough to leave only to have it fail soon after and allow oil to trickle down the back of the engine.

The"complete" gasket sets always seem short of O rings, and the CX has a lot of them.
