Rocker spindle
Rocker spindle for the cylinder head, the shaft the rocker arms pivot on in Triumph 6T, TR6, and T120-family engines.
The 70-1512 is a rocker spindle for the cylinder head, the shaft that the rocker arms pivot on up in the head as they transfer motion from the pushrods to the valves. It shows up across a long run of cylinder block and head figures in the parts books covering 6T, TR6, TR6R, TR6C, T110, T120, and T120R engines, so it's a shaft that saw plenty of service over the years. The older parts book listing for this one is E1512, if that's what you've got written down.

Because the rocker spindle sits directly in the valve gear, wear here shows up as looseness in the rocker action and can affect how quiet and consistent your top end sounds. It's a straightforward wear item to inspect whenever the head is off or the rocker boxes are open for a valve check.
We carry this one in stock. If you're not sure which cylinder head figure matches your engine, bring in your old spindle or give us a call before ordering so we can confirm it's the right one for your setup.
