A repair kit (also called a service kit) for the Onga Leisuretime LTP750 pool pump (0.75 kW, single phase): seal, bearings & capacitor in one order. It suits pumps using Onga 702789. The same parts fit the LTP550. Where the Leisuretime LTP models differ: the LTP1100 uses a different seal (3/4″ (19.05 mm) shaft); the LTP750 takes a 20 µF capacitor where the LTP400 and LTP1100 take no capacitor; the LTP1100 uses a different motor bearing set.
Fits
- Onga Leisuretime LTP550
- Onga Leisuretime LTP750
The Onga Leisuretime LTP750 repair kit holds three parts: a carbon / ceramic mechanical seal for a 1/2″ (12.7 mm) shaft that suits pumps using Onga 702789, a 20 µF 450 VAC CBB60 run capacitor with flying leads, and a matched pair of sealed ball bearings for the drive end and fan end of the motor. The kit costs less than buying the three parts one at a time.
What’s in the Onga Leisuretime LTP750 repair kit
Each part in the kit is also sold on its own, so if you only need one of them you can order it separately. The seal is the same one sold without a model name as our 1/2″ (12.7 mm) jet pump seal.
- Mechanical seal: suits a 1/2″ (12.7 mm) shaft, carbon / ceramic faces, suits pumps using Onga 702789 and Davey 48802SP.
- Run capacitor: 20 µF, 450 VAC, CBB60 motor-run body with flying leads.
- Motor bearing set: two sealed ball bearings, one for the drive end and one for the fan end.
Why service the LTP750 seal, capacitor and bearings in one strip-down
On a pool pump the seal is usually the first part to wear. When it starts to weep, the water tends to run along the shaft towards the motor, and the bearings are the next thing to suffer. Changing the seal already means separating the motor from the wet end, so the bearings can be done in the same strip-down.
The capacitor is the quickest of the three to change. Run capacitors lose capacity slowly with heat and age, so a pump that has been sluggish to get going or has started humming before it spins is often due for one. Doing all three while the LTP750 is apart means one shutdown and one reassembly instead of three.
Before you take the LTP750 apart
Check the model on the pump’s label reads LTP750 or LTP 750. Then compare your old parts with the new ones before fitting anything: the size of the old seal, the µF value printed on the old capacitor, and the bearings in the old motor. If the capacitor in your pump shows a value other than 20 µF, fit that value instead and contact us if you need it. Capacitor details for this pump are in our LTP750 capacitor guide, and unused parts can be sent back under our returns policy. Kits for other Onga pumps are on our Onga repair kits page.
Before you order
Check the old parts before fitting: match the µF printed on your old capacitor and the size of your old seal.
