installing valve seals

JOHN in PENNSYLVANIA · Sep 9, 2008

I just picked up some umbrella valve stem seals for my Farmall A. Any tricks I should know before installing them - thanks

You need to get each piston to TDC on the compression stroke so both valves are closed. You also need an adapter to fit in the sparkplug
hole threads so you can connect an air hose and use air pressure to keep the valves closed. They make a valve compressor or they did years ago so you can compress the valve springs and be able to remove the keepers and springs. Then you can install the valve seals. Then reinstall the springs and keepers. Be careful you don't drop one of the keepers. Hal
PS: I have one of those compressors.

You can also stuff a soft rope through the spark plug hole and turn the piston up to hold the valves.
