Description: Triumph 650 750 Tiger Trophy Bonneville Inlet Tappet Guide Block 1969-79 PN# 70-9352 The tappet guide block houses the tappets, or cam followers, and is pressed into the cylinder block in the intake position. Precise alignment is necessary to ensure the pushrods properly engage with the radiused ends of the tappet stems. This is the inlet guide block with a machined groove to accept an o-ring, as fitted to Triumph B range 650 and 750 twins from 1969-1979. Check your parts book for compatibility. The cast iron guide block is manufactured to original specifications in the UK by LF Harris. The O.D. measures .985 where the pushrod tube fits over the top of the block. Shoulder thickness is .187, and the O.D. of the bottom of the guide block is .985. There is a groove for an o-ring under the shoulder for oil sealing against the cylinder barrel flange. Lubrication to the tappet stems is provided by drillings that pass through the block longitudinally, allowing oil to drain down the pushrod tube from the rocker box. The tappets are a sliding fit in the guide block bores and if the tappet stems or bores in the guide block become worn excessively, mechanical clatter may result. The guide block is an interference fit into the bore of the cylinder barrel. A special drift is used to set the block into its bore. It is advisable to freeze the guide block for several hours and to heat the bore surround under the cylinder barrel flange prior to fitting the block. Its critical that the locking bolt hole in the guide block is in perfect alignment with the threaded hole in the cylinder flange. Installation of the guide block requires precision and skill and may be best left to a professional mechanic or machinist. LF Harris motorcycle spares are produced to the highest quality standards possible utilizing original Triumph tooling, dies, factory blueprints & materials combined with modern manufacturing equipment, tolerances & techniques.
