I dont fully understand the valve assembly process. It says to glue a 3mm jam nut into the spring retainer. Does the end of the 35mm rod need to be threaded?
Use a 45 mm long socket head bolt cut down to 42 mm for the valve stems with the head in the valve and the threaded end in the spring retainer.
Ah, I hadn't thought of that. Two questions if I may. The instructions show 35mm length. And do I cut the head off of the bolt? I dont think the head will fit into the top of the valve.
The head of the bolt fits into the valve. If it doesn't you may have a burr or lump of plastic in the hole.
