The bearing set to suit the Onga Leisuretime LTP1100 is a matched pair of sealed ball bearings for the pump motor: one for the drive end, nearest the pump, and one for the fan end. Replacing both together is the usual fix for a motor that has started to growl, rumble or whine, especially after a seal leak.
Signs the Onga Leisuretime LTP1100 motor bearings are worn
Bearing noise usually starts quietly and gets worse over time. Turn the power off at the switchboard before checking the shaft by hand.
- A growl, rumble or high-pitched whine from the motor that gets worse over time.
- The shaft feels rough, notchy or gritty when you spin it by hand with the power isolated.
- Noise that started some time after the pump had a leaking shaft seal.
Why both LTP1100 bearings are changed together
The two bearings in a pump motor have done the same hours under the same conditions, so when one is noisy the other is rarely far behind. Getting to either one means pulling the motor apart, so fitting a matched pair at once avoids opening it up a second time.
Water is a common cause of early bearing failure. If the shaft seal on the wet end has been weeping, moisture finds its way to the drive-end bearing first. Fix the seal at the same time or the new bearings will go the same way; the LTP1100 service kit includes both, and the LTP1100 mechanical seal is also sold on its own.
Other pumps listed for the LTP1100 bearing set
This bearing set is also listed for four Onga Pantera models: Onga Pantera PPP550, Onga Pantera PPP750, Onga Pantera PPP1100 and Onga Pantera PPP1500. Before pressing new bearings on, compare them with the ones you take out of your LTP1100 motor. If anything looks different, contact us with a photo of the old bearings and the pump label. Seal and bearing kits for other Onga pumps are listed under Onga service kits.
