Laser 90

Description

Laser 90 bearings from RC Bearings are a standard replacement set built for modelers who want their engine running at its best. Every set is made to our own exacting specs using only top-quality parts, with clearances and tolerances tightly controlled for smooth, consistent running and full power. If your Laser 90 has started to feel rough, sound noisy, or lose RPM, a fresh set of bearings is often the simplest way to bring it back to life.

Why Choose RC Bearings Laser 90 Bearings?

OEM bearings can be expensive, and you shouldn’t have to pay a premium just to keep a good engine flying. Our Laser 90 bearings deliver the same level of performance as the originals at a far more reasonable price. They’re a solid choice whether you fly every weekend at the club field, compete, or bring out a scale model on the occasional sunny afternoon.

A four-stroke engine puts its bearings through a lot of heat, vibration, and sustained high RPM, so we pay close attention to fit and finish. Tight tolerances mean less play in the crankshaft, smoother running, and less wear on the rest of the engine over time.

Signs Your Laser 90 Bearings Need Replacing

Bearings wear out gradually, so the early signs are easy to miss. Watch out for:

• A gritty or notchy feel when you turn the prop by hand
• Rattling, whining, or louder-than-usual engine noise
• Trouble holding a steady idle or reaching full RPM
• Visible play or wobble in the crankshaft
• Rust or stiffness after the engine has been stored for a while

If you notice any of these, replace the bearings sooner rather than later, before the damage spreads to the crankshaft or crankcase.

How Do I Install Laser 90 Bearings?

Changing bearings can feel intimidating if you haven’t done it before, but it’s a very manageable job with the right steps. We’ve made a short video that walks you through the whole process from start to finish: Watch: How to Change Your Engine Bearings. Take your time, work on a clean surface, and keep track of each part as it comes out so reassembly goes smoothly.

Tips to Make Your New Bearings Last Longer

A little care after each flying session goes a long way. At the end of the day, run the engine until the fuel is used up, then add a few drops of after-run oil to protect the internals from the residue fuel leaves behind. Store your model somewhere dry, and keep the intake clean so dirt can’t work its way inside. These simple habits will keep your Laser 90 bearings running smoothly for many flights to come.

Laser 90 Bearings FAQ

Should I replace both bearings at the same time?
Yes. Bearings in the same engine wear at a similar rate, so replacing them as a set gives you the smoothest result and saves you from opening the engine twice.

How often should engine bearings be replaced?
There’s no fixed schedule. It depends on how often you fly and how well the engine is cared for. Check the feel of the engine by hand at the start of each season, and replace the bearings as soon as you notice roughness or play.
