Yes. Metric hex keys, drift punch to remove roll pins in control handle assembly. Remove loader for safety and improved access to valve. Clean off valve before removing anything, keep everything clean. Take pictures, helps a lot. No harder than replacing a water faucet.They are the only owner serviceable seals on the valve.
While your doing that remove the cover off the float spool and check for corrosion. The bottom covers also have an o ring under them to seal the bottom of the spool.
Replace the color coded zip ties on the valve/loader hoses before removing. The should all have lost their color by now.
Have you had to replace the control handle yet? It is quite common for it to snap at the threaded connection.
