I've been a little distracted recently, too much going on! In this video, I fix a problem with the non-return vale sticking! Something wierd happening with the sound, looks out of sync and slow!! All the best, Matthew |

Good progress Matthew :thumbup: In the good old days, motor cycle oil pressure relief valves were just a ball bearing pressed by a spring against a cast iron bored hole. The received wisdom (written into maintenance handbooks) was to put a bronze drift against the ball, and give it a firm clout with a hammer, thus deforming the seat to the sphericallity of the ball. Those of us without bronze drifts used a steel rod, then replaced the ball bearing with another identical one, and it seemed to work splendidly. (no lapping allowed as the oil galleries would become contaminated) |

Well, I wasn't sure whether it was the seat or the walls of the valve hanging things up, this way I was able to cove both! More adventures to come! regards, Matthew |
