Suzuki 660cc Valve Clearance & Piston Checking

Powered by a powerful 660cc engine, the Suzuki Carry is one of the most reliable lightweight trucks that one can get. There is also a mini van version which runs using the same engine. For many people who are used to bigger engines as in the case of pick up trucks, one is left wondering what they can get or achieve with a vehicle that only runs 660cc. However, facts stand to prove any doubts. The Japanese mini tucks are well engineered to offer incredible performance and get users excellent results. To get this though, one has to make sure that everything is in perfect shape and well maintained. As part of the maintenance routine, we have covered Suzuki 660cc valve clearance in this post.

The way a vehicle’s camshaft functions along with an engine’s high compression ensures maximum power and performance. However, the downside to this fact is that pistons and valves have increased chances of wearing out. This is especially when there is a high RPM which could damage these components when they come close to each other.

Valve Clearance & Piston Checking

The process of checking and adjusting the clearance is pretty much the same with any petrol engine out there. There are two most common methods that one can use to do this. It is recommended to maintain 0.080-inch valve clearance for the inlet and a 0.100-inch for the exhaust valve. The reason for the exhaust getting more allowance is because of the heat expansion experienced.

To measure the piston to valve clearance, you first need to known compressed thickness of the cylinder. This is usually written in the packaging. Go ahead and measure the uncompressed thickness so as to know the correction factor. This is after measuring the valve travel. You can then go ahead and install the pushrods, lifters and the rocker arms and using a crankshaft, adjust to zero on the compression stroke. By doing this, you are ensuring that both sides of the lifters are in line with the cam lobe.

Next, you need to rotate the crankshaft so that it is tilted at 10 degrees before the exhaust stroke TDC.

Next, you need to position the dial indicator on top of the exhaust valve retainer. Then zero dial that indicator. After this, then you can depress the exhaust valve. To ensure that you get the accurate measurement, just subtract the difference of the gasket thickness.

This is the best way to handle this adjustment. It is a bit of a complex process for beginners. It is recommended that an expert handle this, or at least someone who has enough knowledge about adjusting the valve and pistons.
