"Ron" sent me this idea for a tool to remove the valve springs to change out valve seals, without removing the head, and since it it the perfect example of simplicity, and just plain a good idea, I have talked him into leting me post it in his name........

Here is a picture of the tool I made. You may recognize it as it is the inner plate for the rocker spindle cover.

The bolts are 1/4 - 28 x 1 - 1/2 long

You need good valves with no leaks to keep the valve up or a piece of rope fed into the cylinder and then bring the piston up to hold the valve in place. Just remove the nut from the tappett adjuster , slide the plate on and reinstall nut. Turn the bolts down until they contact the spring retainers. Unless you have permanently fastened the two nuts to the plate you will have to hold on to them until some pressure is exerted on the spring ( no big deal ). Depress the spring , remove the colletts and back off the two bolts . All Done ........................

Pretty clever! I've read about the rope trick before but never could see how to get the valve springs compressed. That's a good one to remember...

yes...have to agree...a good idea, and once again to make this clear, not my idea, but rather an idea from "Ron". I only posted it for him.

Hope all is well out there in the Rockies....things here could be going better..... but could also be worse....just one of those weeks. Broke one of the new compression rings I was trying to install today...just went "ping", so it was time to quit working on the ring job.....took myself into the kitchen....and promptly proceeded to break my favorite coffee mug, which I have had 30 years. Someone up there must be trying to tell me something.... :lol:

Old thread here... need some help. Replacing an inlet valve seal. Used a rope to hold the valve up, no issues there.

Used spring compressor tool seen here, got the collets off, removed the spring compressor tool, but I see no way to extract the springs with the rocker in the way. Been puttering around with it for awhile now, I got the spring cover off by removing the valve adjustment stud and lowering the pistons a bit to allow the valve to lower, but can't remove either spring. Any advice?

Cheers,

After a phone chat, it was decided to simply back the adjuster all the way out, flip the rocker down, slide the pushrod out of the way, they flip the rocker all the way up to allow total clearance.

Hungry joe should be cheking back in a while with positive results of new seals slipped in place.

Nice tool.

The bad news is if you've got mushroom headed adjusters it's still probably a head off job.

Nah, just take the rocker out and lever off the head steady.

same principle , but a little neater :

Yes but still doesn't help my issue... I have no problems getting the split collets off and the spring cover, but with the rocker arm there can't get the darn springs to get to the valve seal...

Got a little more clearance by fiddling with the pushrod on the rocker... messed around with it last night until I started getting frustrated. Left off rather than damaging something, will have another go this afternoon.

Worse comes to worse I guess the rocker arms will have to come off... I'll have to be sure I don't overheat the head and melt the rope that is now in my combustion chamber...

I thought Paul told you to move the pushrod out of the way?

Boy am I dumb...

Went to the garage to start again. Took one look and realized in my haste last night to replace the seal I was working on the exhaust valve...

So lesson learned, think before you act. Glad I stopped when it wasn't working out though and didn't try to force anything...

Have to put the collets back in the exhaust valve, and will report back once the inlet is fixed!

Cheers,

I guess you haven't done this job yourself because "sliding the pushrod out of the way" is simply not possible (unless you reduced the rocker-ends like Dunstall) with the standard valve train since there is no room to clear the pushrod sideways from the rocker-end to flip it back over, so you have to remove the rockershaft and rocker to change the seal.

BINGO, forget any speed advantage but for ease on about any and every head job, suck out rockers and grind off enough that push rod fouling is never ever an issue again. Make head removal-replacing a few minutes job rather than tedium strain.
Norton rockers are the most over built item on bike even more so than Z plates.
Your call but no time like present when into it anyway.
Rocker spindles should mostly just slip in and out light tapping maybe to full seat.

Sometimes the quick fix gets complicated to the point where the long option is a lot easier, I think taking the rocker shafts out in situ is somewhere I wouldn't bother going.

ludwig has obviously gone to the trouble of making a nice tool for this. How do you accomplish the whole task? I was following the process up to the point of having the retainers out and after that I get lost. How you you get the springs out and then reassemble everything.

After you got the retainers out (assuming your rockers are standard) you locally heat the head and extract the rockershaft and rocker. Now you can remove the springs and change the seal. Then reverse the procedure.

Thanks for the explanation. I know it is a pain to remove the head, but it seems pretty close to the same hassle to do this method. The head isn't really that bad, just time consuming.

???..
I bet I can change both valve seals before you even have taken off your air filter , carbs , headsteady , oil line , exhausts ..
and spend the money for the head gasket on a few beers , watching you struggle with those slippery pushrods ..

(but I promise : I won't take advantage of your bent over position ..)
