Re: Tacho coil Hpt WM68 1601617 NLA?
The tacho you need is the small open one with the metal bar across the back. The tacho magnet is the type that is dished both sides and made of a plastic material that splits easily.
This motor was for the 415 control and the tacho is different from the old type that had the adjustable cap with the 2 ‘fingers’ that pressed over the coil.
If all else fails, you can PM me your address and I’ll post you a s / hand coil. 😉
