The HA76 looks VERY much like a H150 and shares the center spacing. It looks truly original to my 2000 H16 traveler and seems 100% interchangeable. Here is a comparison from the underside:
They are now known as Allen - it's a British company - and it's a current product which seems to be of good quality. But my Hobie dealer sells H150 springs and probably not HA76 parts, so it's probably in my best interest to have a H150 there. I'll clean up the HA76 and keep it as a backup.
The H150 uses three bearing layers of 11 balls, while the HA76 has two layers with maybe 15 on the bottom and 14 on the top. I haven't had a chance to see if they are flattened.
As I mentioned I DO have a broken spring but that isn't justification for getting the rebuild kit, as the springs are available individually. I'm wondering if anyone has used the rebuild kit and noticed an improvement from it.
