7 Harley Davidson 96 Cubic Inch Engine Problems & Solution
Several problems can be encountered when operating a Harley-Davidson motorcycle with a 96 cubic-inch engine. Since this is a relatively large engine, it may require more maintenance than other models.
If you need help with the current condition of your bike and are looking for solutions to the problem, consider consulting an expert. The expert can help you diagnose the problem and provide appropriate recommendations to maintain your bike running well. Here are 7 of the common problems and their possible solutions:
1.Cam Chain Tensioner Recall
Cam chain tensioners are devices that help keep your camshaft in check. They work by applying tension to the chain when rotating, which helps prevent it from becoming too loose or too tight. If a cam chain tensioner is damaged, it can cause several issues, including faster wear on the camshaft and increased fuel consumption. You can repair a damaged cam chain tensioner by replacing the unit’s seals, gaskets, and o-rings.
However, you found this design could have been better, with plastic shoes that can wear out easily, leading to metal-to-metal contact and engine failure. To address oil-scavenging problems, Harley-Davidson incorporated a dual scavenge system into the engine, restricting the diameter of the inlet to solve the problem counterintuitively.
In addition to improved cam chain tensioner design, Harley-Davidson also developed an improved cam chain assembly that improves oil flow and service life.
2.Oil Pump
The Harley 96 cubic inch engine has issues with the oil pump getting jammed. To combat this, Harley-Davidson introduced a dual scavenge system in the engine to increase oil scavenging and improve the system’s longevity. In addition to this, the Twin Cam 88B engine variant was designed to address visual styling issues.
To improve the longevity of the oil system, replacing the cam chest with a hydraulic oil pressure kit can help ensure that the system can continue to work efficiently over time. Upgrading to a higher-quality oil and a fan-assisted oil cooler can help eliminate future cam issues. Maintaining and regularly servicing your Harley-Davidson motorcycle’s engine ensures its reliability and performance over time.
3.Bearings
Many people consider the Harley Davidson 96 cubic inch engine to be one of the company’s best. Despite its impressive performance and capabilities, it has experienced some issues related to the cam chain tensioner and worn cam-plate bearings.
The cam chain tensioner is a small cylinder located in the engine that controls the camshaft movement. It works by always applying a pre-determined amount of pressure to the camshaft, regardless of engine RPM. However, with age and wear, this cylinder can lose its ability to apply enough force to the camshaft, resulting in excessive engine wear and operational problems.
The bearings on Harley Davidson motorcycles can be problematic due to the engine’s vibrations. Over time, these vibrations can cause the bearings to fail prematurely. The best way to address this problem is to inspect the bearings and replace them regularly as needed.
In addition, using the correct grade of bearing for the bike is important, as using the wrong grade can lead to further problems down the road. Regular maintenance and inspection will help ensure the bearings last as long as possible.
4.Ignition System Problems
Issues with the ignition system of the Harley Davidson 96-cubic-inch engine have been reported, such as issues with using a single coil in the Evo engine and deploying double coils in the Twin Cam 88 engine. You also knew the Twin Cam 88 to have a weak chain drive system.
Dealers advise their customers to watch out for cam-support bearing issues with the TC-88 engine. However, mechanical tension arms in cam chests were left unchanged, resulting in poor cylinder filling and reduced performance. Hence, customers must be careful when purchasing or servicing this motorcycle model and ensure everything is up to date and working properly.
5.Cylinder Head Problems
The Harley Davidson 96 Cubic Inch engine has suffered from cam chain tensioner, oil pump, and cylinder head problems. The cam system in the H-D engine typically consists of cams located on the camshafts and cam lobes that move inside the cylinder heads when the engine is operating. Camshafts have various lengths and diameters, allowing for different exhaust and intake requirements of a specific engine design.
However, over time, hardened steel camshafts can wear out. Suppose there are problems with the cam chain tensioner, oil pump, or cylinder head in a Harley-Davidson 96″ motorcycle engine. In that case, there could be loud and unpleasant thrashing sounds coming from the engine whenever it is running.
Additionally, worn-out cam lobes can lead to a rough-running engine that makes a rattling or whining sound. If you notice any of these symptoms in your motorcycle’s engine, be sure to have it checked immediately by a trusted mechanic.
6.Cylinder Block Problems
A few issues can occur with the cylinder block on a Harley Davidson. One of the main concerns is wear and tear. A worn cylinder block can cause an increase in friction and damage to internal components, such as valves, spark plugs, and pistons.
This results in reduced performance and increased fuel consumption. Another problem that can occur with cylinder blocks is cracking. Cracks form due to thermal expansion or contraction of the metal, which can lead to leakage of oil or coolant into the combustion chamber.
Finally, some cylinders have been known to experience failures due to manufacturing defects or improper assembly during production. These issues can be tricky to track down because they may only be apparent with close inspection by a technician. If you notice any of these issues on your engine, bring it in for a thorough inspection so no further damage occurs.
7.Carburetor Problems
A few common problems can occur with carburetors on Harley-Davidson motorcycles, including clogged jets, stuck pilot jets, and excessive idle. You may need to remove and clean the carburetor to fix these issues. If the issue persists, contact a mechanic for help.
If your Harley-David has an excessively rich or lean fuel mixture, check the pilot jet for debris or other obstructions. Use a cleaning solution or wire brush to clean the jet if necessary. Also, adjust the fuel mixture screws on the throttle body to fine-tune the engine’s fueling characteristics. If your Harley runs rough or is losing power when accelerating, check the air filter for cracks and replace it if necessary.
Maintenance Tips On Harley Davidson 96 Cubic Inch Engines
Harley Davidson engines are some of the most popular worldwide, and for a good reason. They are powerful, versatile, and easy to work on. However, like all engines, they require regular maintenance to keep them running smoothly.
Here are a few maintenance tips for Harley Davidson 96 cubic inch engines: Regularly check the oil level and filter. Engine oil is essential for preventing engine damage; a clogged filter can cause serious problems. Check the air filter and clean it as necessary. Air pollution can cause engine damage, so keeping the air filter clean is important.
Check the belts and replace them as needed. Belts play an essential role in ensuring the engine operates properly, so it is important to replace them regularly.
