How Do You Get To Your Nuts?

[tony.barnett]

A question to White and Poppers - removing a barrel I've always had to take the valves and springs off first to get to the base flange nuts. Definitely makes removing and replacing a barrel a more time consuming process that it needs to. So, my question - has any of you figured out how to get to the nuts behind the tappets on a W&P engine without removing the valves and springs?

Hi

The clearances are not well defined in the photos, but my first approach would be with the ring end of a combination spanner suitably ground down and thinned to fit, as well as moving the push rods to maximise access.

Thanks Mick - I've tried grinding down a ring spanner - there just isn't enough room, and if you do get the spanner over the nut the tappet is in the way.

Hi Tony

Have you considered using modifying the nuts, (reducing head size and or height)?

Thats not a bad idea. I'll see if I can find reduced hex nuts in that size.

What is the stud diameter and thread?

How about manufacturing double nuts? Full size nut at the base with a smaller hex nut for your ring spanner on top? Wouldn't compromise the clamping diameter of the lower nut?

Hmmmm....thats worth a look. Thanks
