SHAFT&ADJUSTING PLATE MANIFOLD HEAT CONTROL
CC614976
Shaft & adjustment plate manifold heat riser
For exhaust manifold with heat riser
Shaft with adjustment plate for the heat riser mechanism of the exhaust manifold. This component is part of the automatic system that, when the engine is cold, partially redirects exhaust gases to warm up the inlet manifold more quickly, which is particularly important for starting and driving in low temperatures.

★ Essential component for proper functioning of the manifold heat riser mechanism. During cold starts, the system helps the engine reach operating temperature more quickly.
Application
For engines with L-134 F-head specification fitted with heat riser in the exhaust manifold. The shaft runs through the manifold and carries the butterfly valve plate that regulates the exhaust gas flow. When the engine is cold, the valve is closed to direct exhaust gases through the inlet manifold; when warm, the bimetallic spring opens the valve fully.
Installation notes
The shaft is mounted with bushings on both sides of the manifold. Check that the bushings are not seized. The adjustment plate must be correctly aligned with the shaft slot. The bimetallic spring is fitted on the external side against the stop, allowing the spring to rotate the shaft and valve as it warms up. The valve must be rotated fully clockwise during assembly before the spring is installed.
Compatibility
Exclusively for manifolds with heat riser provision. Not all engines have this system – check whether your manifold has drillings for the shaft. Note: some original valves were welded to the shaft, others secured with screws – fitting a new shaft may require modification of the fixing method.
Historical context
The heat riser system was standard on WWII jeeps and early post-war models to achieve operational readiness more quickly in cold conditions. The bimetallic spring mechanism operated entirely automatically without driver intervention.
