If you didn't replace the cam chain the marks may not line up exactly. A line on the camshaft sprocket that is lined up with the top of the cylinder head.īe sure to leave the camchain tensioner off till everything is lined up and the cam bearing caps torqued down. A line on the cam that is lined up with the top of the cylinder head. These marks can be a circle on the camchain sprocket that is matched to a mark on the cylinder head. Now the camchain is moved on the sprocket till the timing marks are set. Then the camshaft is installed with the Cam lobes pointed down and the camchain is looped over the cam sprocket. The "T" mark on the flywheel aligned with the mark on the crankcase. On single cylinder engines the piston must be set at TDC. Sounds so easy does it not? It really is, but here are some things to remember. Set the engine at Top-Dead-Center (TDC) of the compression stroke, set the timing marks on the cam and you are done. I guess we all fall short.Įvery time we assemble a four stroke engine we have to set the valve timing. Why I didn't do it on the camshaft timing marks, which is the whole object of this page. I did make careful notes on this balancer when I disassembled it and I found the balancer marks too.

Not a word on how to time it right in the balancer section of the manual. Get the balancer timing off and this engine will Wiggle like a Belly dancer ! I finally found some sort of instructions in a completely different part of the manual.

I looked and looked in both manuals and they simply did not cover setting up the timing on that balancer.

The factory manual AND an after market manual from a well known publisher. This engine had a counter balancer in it. You probably will never have to do this, but you can if it's necessary. Write it all down or take a digital picture of it. If it's a twin cam engine count the number of rollers between marks you put on the camshaft intake and exhaust sprockets. I suppose you could use a small punch mark, but I like paint better. To make your own marks (BEFORE you take it apart) just set (turn) the crankshaft so the #1 cylinder is at TDC (Top-Dead-Center) on the compression stroke (Both intake and exhaust valves closed) and then make some marks on the camshaft sprocket(s) and a corresponding mark on the cylinder head. Factory manual cam marks were 180 degrees off) (The manual was wrong on my Chevy LOVE truck. I have found that even the factory manuals can be wrong. I try some other marks and that looks better. I try what seem to be the factory marks but the cam lobes just don't look positioned right. Now what? Who knows who made these cam sprockets and what marks they used. I go to reassemble the engine and the marks DO NOT MATCH the marks given in the factory shop manual. Then I discovered it had some weird, aftermarket, simi adjustable, cam sprockets. On the last engine I rebuilt I forgot to do it, trusting in the factory shop manual I had. I do this on every four stroke engine I disassemble.
On twin cam engines I count the number of cam chain rollers from the exhaust cam mark to the intake cam mark and write that down too. Do the marks on the cam or cam sprocket match up with what the manual says? If they DON'T, I write down the marks that are used and how they are used so that on reassembly I can reproduce the correct cam (valve) timing. Set the engine at TDC (Top-Dead-Center) Of the compression stroke (TDC on the #1 cylinder if it a multi cylinder engine). What do I mean? Well, LOOK at the camshaft marks BEFORE you take it apart. This is quite simple IF we play by the rules.Īssembly actually starts with disassembly. What we want is to reproduce the original factory setting. Then we would want to degree in the cam(s) with a Degree Wheel bolted to the crankshaft. We don't really need to concern ourselves with the initial set up unless we have modified the engine and changed the cam to a high performance one. All this opening and closing is set at the factory and is all quite complex. The exact time the intake valves and exhaust valves open and close will effect the amount of power produced by the engine and at what RPM it is produced.
Valve (Cam) timing can be quite complex or quite simple. Worse still, if the valves open at the wrong time they can be hit by the piston and bent. However, if these valves don't open and close at the right time the engine will not run. ¶ To let the air/fuel mixture in to the engine we have intake valves.
