Valve spring tool to remove valve spring with engine in frame
« on: June 17, 2019, 02:59:44 PM »
Has anyone made a tool for removing the valve springs with the engine in frame? Both lower frame tubes are removed and compressed air will be in the cylinder.

Thanks in advance.

The best trick I’ve seen is to stuff thin cotton rope into the cylinder, rotate that cylinder to TDC, rap on the retainer and remove the keeper. You can do this only to replace springs one cylinder at a time. Else, you run the risk of dropping the valve into the chamber deep enough to damage the guide or seat with the stem.

^^^^+1 That is the BEST way to do it without removing the head. Just remember to leave a long enough piece hanging out of the plug hole to pull the rope back out. (Sorry, I had to state the obvious) ;)

yes that will work.
then if you wonder how to get them back on... you can make yourself a contraption like this:



from these parts:



- piece of tube, cut out to give access to the keepers
- something as a lever (tyre iron in my case)
- something to be used as a fulcrum for the lever
- 6mm bolt to fix fulcrum to head
- piece of rope to hold fulcrum down

 Air works fine except it wants to turn the motor sometimes, I'm thinking something like a pickle fork with a pivot off the rocker shaft.

I have one that attaches on the rocker arm pivots; a length of rope in the combustion chamber and voila! I will look for it under my bed to get you pics

Why not lifting the head? Leaking seals?
Easy with frame kit.
The seats might need a cut or valves to be lapped.

 For insertion into the plug hole, I've also used a quality silicone jacket plug wire. It pushes easier. My big block chevy uses a spring compressor that bolts down and screws over the retainer for install/removal.
