Milwaukee 8 Oil Pump Upgrade: Boost Your Ride (Full Guide)

If you’re a Harley-Davidson owner, you know that regular maintenance is crucial to keeping your bike running smoothly.

One critical component of your engine is the oil pump, which ensures that your engine stays lubricated and runs at peak performance.

In this blog post, we’ll explore the Milwaukee 8 oil pump upgrade, a popular modification among Harley enthusiasts that can improve your bike’s oil flow, increase oil pressure, and provide better cooling for your engine.

Milwaukee 8 Oil Pump Upgrade

Step 1: Determine the Right Oil Pump for Your Engine

Before you start the upgrade process, you’ll need to determine which oil pump is right for your Milwaukee 8 engine.

There are many aftermarket oil pumps available, but not all of them are compatible with your specific engine.

Check the manufacturer’s specifications to ensure that the pump you choose is suitable for your engine.

Step 2: Gather Your Tools and Materials

To upgrade your oil pump, you’ll need a few tools and materials. Here’s what you’ll need:

• New oil pump
• Oil pump gasket
• Torque wrench
• Socket wrench set
• Allen wrench set
• Oil filter wrench
• New oil filter
• Clean rags
• Oil drain pan

Step 3: Remove the Old Oil Pump

To install your new oil pump, you’ll first need to remove the old one. Start by draining the oil from your engine and removing the oil filter.

Then, use a socket wrench set to remove the bolts that hold the oil pump in place.

You may also need to use an Allen wrench set to remove any additional bolts or screws.

Once you’ve removed the old oil pump, clean the mounting surface with a clean rag to ensure that there are no traces of debris or oil left behind.

Step 4: Install the New Oil Pump

Once the old oil pump has been removed and the mounting surface is clean, it’s time to install the new oil pump.

Place the new oil pump into position and use a torque wrench to tighten the bolts to the manufacturer’s specifications.

Make sure to use the new oil pump gasket to create a seal between the pump and the engine.

Step 5: Install the New Oil Filter and Add New Oil

With the new oil pump in place, it’s time to install a new oil filter and add fresh oil to the engine.

Use an oil filter wrench to remove the old oil filter and install the new one. Then, fill the engine with the recommended type and amount of oil.

Step 6: Test Oil Pressure

Test the oil pressure to ensure that the new oil pump is functioning properly.

This typically involves starting the engine and monitoring the oil pressure gauge or light to ensure that the oil pressure is within the manufacturer’s specifications.

Step 7: Final Checks

Perform a final check of the oil pump and surrounding area to ensure that there are no leaks or other issues.

It’s also a good idea to check the oil level and perform an oil change to ensure that the engine is properly lubricated.

Benefits of upgrading the oil pump

Upgrading the oil pump in a vehicle can provide several benefits that can improve its overall performance and longevity.

Here are some of the benefits of upgrading the oil pump:

Improved Lubrication:

An upgraded oil pump improves lubrication by providing a more consistent flow of oil.

This improved lubrication helps to prevent wear and tear, reduce the likelihood of damage, and increase its lifespan.

Better Oil Pressure: 

An upgraded oil pump can also provide better oil pressure to the engine, which can help improve the engine’s performance.

Better oil pressure can result in better fuel economy, smoother operation, and increased horsepower.

Increased Cooling: 

An upgraded oil pump can also help increase the engine’s cooling efficiency.

By providing a more consistent flow of oil to the engine, an upgraded oil pump can help regulate the engine’s temperature and prevent overheating.

Better Filtration:

An upgraded oil pump can also help improve the filtration of the engine’s oil.

This can help remove contaminants and particles from the engine’s oil, preventing damage to the engine and increasing its longevity.

Signs that you need an oil pump upgrade

Several signs may indicate you need an oil pump upgrade for your vehicle. 

Low Oil Pressure: 

One of the most obvious signs is noticing a drop in oil pressure. This can identify by a warning light on the dashboard or by a gauge that shows low oil pressure.

Low oil pressure can indicate the oil pump’s low providing oil to the engine.

Engine Noise: 

If you hear unusual noises coming from the engine, like ticking or knocking sounds, it indicates low providing lubricant to the engine’s moving parts.

This cause wears and tear on the engine and leads to serious damage over time.

Overheating: 

If your engine is running hotter than normal, that means the oil pump is not providing enough cooling to the engine. This cause the engine to overheat and cause serious damage.

Oil Leaks: 

If you notice oil leaks in the engine, it may the oil pump is not functioning correctly.

Oil leaks can also be caused by worn or damaged seals, so inspected the vehicle by a professional to determine the cause.

Reduced Performance: 

If your vehicle’s performance is reduced, it may be a sign of not providing enough oil to the engine. This can cause a decrease in power and overall performance.

Types of oil pump upgrades available

There are several types of oil pump upgrades available for vehicles, each with its own benefits and drawbacks. 

High-Volume Oil Pumps: 

High-volume oil pumps provide a greater volume of oil to improve lubrication and cooling.

This type of oil pump is often used in high-performance engines. High-volume oil pumps can sometimes cause increased issues regarding the engine and incorrect installation.

High-Pressure Oil Pumps: 

High-pressure oil pumps also provide greater oil pressure, which can improve performance and reduce wear on the engine’s moving parts.

This type of oil pump is often used in turbocharged or supercharged engines.

High-pressure oil pumps can sometimes cause increased wear on the engine and lead to oil leaks.

Billet Oil Pumps: 

Billet oil pumps are made from high-strength materials and designed to provide improved durability and performance.

This type of oil pump is subject to extreme operating conditions. Billet oil pumps can be more expensive than other types of oil pumps, but they can provide improved reliability and longevity.

Gear-Type Oil Pumps: 

Gear-type oil pumps are designed to provide a consistent flow of oil to the engine to improve lubrication and cooling.

This type of oil pump is often used in older or vintage vehicles. Gear-type oil pumps can sometimes be noisy and may require more maintenance than other types of oil pumps.

Electric Oil Pumps: 

Electric oil pumps provide a more precise and consistent flow of oil to the engine, which can improve performance and reduce wear on the engine’s moving parts.

This type of oil pump is often used in hybrid or electric vehicles. Electric oil pumps are more expensive than all oil pumps.
