Need to change valve spring

Postby goldminerusa » Fri Jul 06, 2012 10:10 pm



While doing the valve clearences on my 82 1100, i found a broken outer intake valve spring on #3. Got another full set of springs(ebay), My question is, do i really have to remove the timing belts, cam, fuel pump etc. to remove the rocker assy? Seems to me i should be able to leave all that in place and unbolt/remove the rocker assy. Keeping the cam sprocket/belts under tension and same for fuel pump will keep the cam from falling out, no? Then i just fill the combustion chamber with rope, rotate the piston to TDC to keep the valve in place and do the replacement. All help appreciated Thanks.

Using the rope is a nice trick. I usualy get an adapter like in a cyl leakdown kit and pressurize the cylinder to keep the valves in place. Then get a valve spring compressor like the one at harbor freight that clamps down the spring. Remove the keepers, replace the spring using the clamp and install the keepers. The spring clamp allows you to change the springs without removing the head.

Go to harbor freight website and search universal valve spring compressor to see what I'm talking about. It is item #92900.

Fairly sure it all has to come off..but it been a while since I've been in a head..don't see how you can remove a spring w/o the tappets being out of the way and that means the whole assembly..??

See about halfway down how the rocker shaft is removed without removing the camshaft, belts, or anything else.

SteveB123, My sincere THANK YOU for posting the link to this article, both for myself and all the other GoldwingDocs members. WingAdmin, can this article be put in How-To Articles? Saves alot of time and energy for an otherwise simple procedure and adds a new dimension of performance improvement.

Very good How to..but those are off the bike..very hard to do that on the bike only works for one shaft. The NGW site has lots of great How to's as does this site.

Sorry. I never posted the results of this repair. Rbgerson commented the head was off the bike, I did the repair with the head on and had no problems, i used a 90 deg. bent long handle needle nose pliers to get the shaft started out from behind the cam sprocket end. That was the hardest part. But, like the NGW site article says you`ve got to be aware of the oil holes when you put the shaft back in, or it wont spray oil.
