Rocker arms pivot on the rocker shaft and transfer motion from the pushrod to the valve, so this is a wear item worth checking any time you've got the rocker box open. Because Triumph rocker arms are handed for exhaust and inlet sides, make sure you're ordering the one that matches the position you're working on rather than assuming they're all interchangeable.
Given the figure history here, this one belongs to the later cylinder heads used across the T140/TR7 range. If you're not sure which head or year your rocker box is off, bring the old part to the counter or give us a call before you order so we can confirm you're getting the right side.
