How to Make My RV Generator Less Noisy

Generators allow you to run electrical appliances while on battery power. They also require gas to run and will kick off when the RV becomes too low on fuel. Some are very noisy. But dampening the noise can be an easy fix, depending on where it is coming from.

Things You'll Need

• 10W50 oil
• 3M dampening product
• New motor mounts
• Assorted wrenches

Instructions

1. Find out what is causing the noise by running the generator and listening.

2. Apply 10W50 oil to eliminate the noise of a piston slap. Rebuilding the generator's engine will also solve this problem if it is extensive.

3. Replace the lifters if the noise is coming from the valve area.

4. Replace the motor mounts by unscrewing and adding new pieces. This could cause a low frequency noise from rotted or dried out parts. This should stop a lot of the noise from the generator vibrating.

5. Replace the exhaust pipes so they extend past the body of the RV. Also, check that the exhaust pipe has no holes in it.

6. Apply a 3M dampening product if the noise is coming from the compartment where the generator is mounted. This will stop the vibration. Also, 3M makes a product used to reduce the noise of car doors. Spraying this product on the compartment box will quiet it down.
