Cylinder Head U20
Engine Timing Components 2000
Datsun Roadster 2000 Upper Tensioner Shim Kit W/Gaskets Tensioner not included
Keep your upper tensioner tight and prevent the deadly death rattle that accelerates wear to your, expensive to replace, timing parts. A tensioner that sticks out to far will have to fill each time, thus moving from the relaxed position to the fully, extended hydraulic position, each time the engine starts, with the result of a rattling chain slapping against the guide rails and sprockets. Great little kit for those of you that can't afford new pieces or have worn pieces or an overly planed cylinder head resulting in the tensioner shoe sticking way out.
Directions: Start and run the engine until the oil gauge shows pressure, usually about 15 seconds to 30 seconds. The tensioner is last in line to receive oil pressure. Remove the valve cover and the front access cover. The upper tensioner should be tight against the chain and the chain should be tight on the other side of the cam sprocket. Measure the distance between the back of the shoe and the front of the cast tensioner housing and take note of the distance. Take one of the zip ties and work it through the front of tensioner and loop around the cast housing. Pull and tighten the zip tie as tight as you can make it. Put a rag underneath the tensioner area to keep the bolts from falling down into the engine. Loosen the two bolts and extract the tensioner. Hold the tensioner and cut the zip tie and remove the shoe. Add the washers included in the kit to make up the distance you measured. Put the other zip tie around the assembly and tighten. Reassemble the tensioner/spring, with the gasket supplied, into the engine and tighten down the bolts. Cut the zip tie and assemble the access plate with the new gasket.
