paiyan To ensure it absolutely 100% fits perfectly….you would do best to get the parts from ACS. This way they will all fit the group perfectly.
If this is too expensive, you need
- upper group valve assembly
- lower group valve assembly
- upper group valve spring
- lower group valve spring
- two lever o rings for the lever stem as it passes into the group
You do not need the preinfusion valve, or the preinfusion valve spring as the spring is removed and the -preinfusion (middle) valves job in that group is only as a pusher for the lower (vent valve) to open. You also definitely don’t need the lever cam as that is groound to a particular custom specification and won’t have worn anyway.
These parts should bring your group back to full working order. The parts should not cost more than 30-40 AUD
