The Onga Leisuretime LTP750 bearing set is a matched pair of sealed ball bearings: one for the drive end of the motor, nearest the pump, and one for the fan end. Both come in the set because they wear together and are reached in the same strip-down. Compare them with the bearings in your old motor before pressing them on.
Signs the Onga Leisuretime LTP750 motor bearings are worn
Bearing noise usually builds gradually rather than appearing overnight, and it is often a knock-on effect of a seal that has been weeping into the motor.
- A growl, rumble or rising whine from the motor that is louder than it used to be.
- The shaft feels rough, notchy or gritty when turned by hand with the power isolated.
- Side-to-side play at the shaft end, or the fan cover rubbing.
- Rust staining around the drive end of the motor where water has got in.
Why both bearings are changed together
The two bearings carry the same shaft and see the same hours, heat and any moisture that has crept in. Once the motor is opened to replace one, the other is already exposed, and an old bearing left in place is often the next thing to go. Changing the pair means the LTP750 motor only has to come apart once.
Other pumps listed with the LTP750 bearing set
These pumps are listed with the same pair of bearings: Onga Leisuretime LTP400, Onga Leisuretime LTP550, DAB Jet 82M, DAB Jetinox 90M and DAB Jetinox 110M.
Fitting the LTP750 bearings
Draw the old bearings off with a puller rather than levering them. When fitting, press only on the inner ring so the balls are not loaded through the outer ring, and use a tube or socket that sits squarely on it. Never hammer directly on a bearing. If water caused the wear, fix the leak too: the LTP750 mechanical seal is the usual culprit, and the LTP750 service kit bundles the seal, bearings and capacitor.
Before you order
Check the old part before fitting: match the bearings in your old motor.
