If the belt wearing or other problems continues even after proper setup, make sure to use the right-sized belt, have the 2 pulleys perfectly aligned, or get a better torque converter. Step 5: Mount the belt in between the pulleys.Īnd that’s it, time for you to test out if everything works fine. (Recommended torque by Comet is 24-30 ft-lbs)

Step 4: Bolt the outer half of the driver into the crankshaft with the bolt and lock and flat washer that comes with the setup. Belt will remain as close to straight alignment as its going to get during the shifts. Driver will squeeze the belt away from engine, and driven will inhale the belt away from the engine also. Both driver and driven as set up will move the belt away from the engine as they shift together.

If your setup comes with a backplate and you want to install the backplate, then you’ll need to bolt down the middle holes on the plate into the 4 holes on the engine (the holes will be near the crankshaft). The 40 series has a V-belt and V-pulleys. Step 3: Slide the Driver pulley into the crankshaft, such that the fixed part is facing the engine (look at the diagram above for reference). Step 2: Slide some washers into the crankshaft, so that the driver and the driven pulleys can be aligned and also gives some clearance between the engine and the driver pulley. Step 1: Fix your Driven pulley into your jackshaft, if the spring in the driven pulley is red then the cam will face the engine and if the spring is yellow, then the movable parts will both be on the same side (opposite to the engine) Similarly in other symmetrical belt systems, torque converters such as the 20 series and the 500 series, all have the cam facing the engine. Here’s the setup diagram from comet 40’s user manual for the red spring. If you want to install the torque converter such that the cam is facing outwards, then you will have to replace the red spring with the yellow spring also called the “reverse springs“. Such that the cam of the torque converter is facing towards the engine. If the movable half of the driven pulley comes with a red spring, the movable half of the driven pulley has to be placed in the opposite direction to the movable half of the driver pulley. If you do install it the wrong way, you will end up wearing out your belts and losing a lot of power. In fact, the few videos on 40 series install out there can also get you confused. Unfortunately, many people end up installing the 40 series the wrong way, mainly because all the tutorial videos and articles are about the 30 series and people assume that the 40 series are installed the same way. The 40 series torque converters are the go-to for 8-18hp Engines such as the predator 301, predator 420, or the honda GX 270 or GX390 and their other clones.
