Step-by-Step Guide to Installing the Spring Gear

Alright, let’s get down to the nitty-gritty of installing the spring gear on your Saga BLM. Follow these steps carefully to ensure a successful installation.

Step 1: Preparation and Safety

First things first, safety! Park your Saga BLM on a level surface. Engage the parking brake and use wheel chocks to secure the rear wheels. Loosen the lug nuts on the wheel of the side you'll be working on. Use a jack to lift the car and then secure it with jack stands. Never work under a vehicle supported only by a jack. Disconnect the negative terminal of the battery to prevent any electrical mishaps during the spring gear replacement process.

Step 2: Accessing the Spring Gear

Locate the timing cover on the engine. This cover protects the timing components, including the spring gear. You might need to remove some ancillary components, such as belts, hoses, or brackets, to gain clear access to the timing cover. Use your socket set and wrenches to carefully remove these parts, labeling them as you go to make reassembly easier. Once you have a clear view of the timing cover, remove it by unbolting it from the engine block. Be careful not to damage the gasket, as you may need to replace it if it's in poor condition.

Step 3: Removing the Old Spring Gear

With the timing cover removed, you'll now have access to the spring gear. Before removing anything, make sure the engine is set to Top Dead Center (TDC) on cylinder number one. This ensures that the timing marks are aligned, which is crucial for proper reassembly. Use your socket set to carefully unbolt the spring gear. If the bolts are tight, apply some penetrating oil and let it sit for a few minutes before attempting to remove them again. Once the bolts are removed, carefully pull the old spring gear off. Inspect the surrounding components, such as the camshaft and crankshaft, for any signs of wear or damage. Now is a good time to address any other issues you might find. With the old spring gear removed, you're ready to move on to installing the new one.

Step 4: Installing the New Spring Gear

Before installing the new spring gear, make sure it's the correct part for your Saga BLM model. Apply a light coat of oil to the new gear's contact surfaces to ensure smooth operation. Align the timing marks on the new spring gear with the corresponding marks on the engine block and camshaft. This is extremely important to ensure proper engine timing. Carefully slide the new spring gear onto the camshaft, making sure it sits flush against the mounting surface. Use your socket set to bolt the new spring gear in place. Tighten the bolts to the manufacturer's specified torque settings using your torque wrench. This prevents over-tightening, which can damage the gear or the engine block.

Step 5: Reassembly

Now that the new spring gear is securely in place, it's time to reassemble everything you disassembled earlier. Start by reinstalling the timing cover, making sure to use a new gasket if the old one was damaged. Bolt the timing cover back onto the engine block, tightening the bolts to the specified torque settings. Reattach any ancillary components you removed earlier, such as belts, hoses, and brackets. Refer to your labels and notes to ensure everything goes back in the correct place. Double-check all your connections to make sure nothing is loose or out of place.

Step 6: Final Checks and Adjustments

After reassembling everything, reconnect the negative terminal of the battery. Lower the vehicle and remove the jack stands. Tighten the lug nuts on the wheel to the specified torque settings. Start the engine and let it idle for a few minutes. Listen for any unusual noises or vibrations. If everything sounds normal, use a timing light to verify and adjust the engine timing. This ensures that the engine is running at its optimal performance settings. Take the car for a short test drive to make sure everything is working correctly. Pay attention to the engine's performance and listen for any signs of trouble. If you notice any issues, address them promptly.
