Product Description

Standard tune up kit for the Hayward Northstar pump includes the shaft seal and all o-rings, gaskets and lubricant.

We highly recommend replacing the shaft seal, o-rings and gaskets when replacing your motor.  If you use your old shaft seal, it will not mate up properly with the new motor and may leak.

This Tune Up Kit Works on These Pumps:

  • All Hayward Northstar Pumps (1998-2002) 1/2 HP - 3 HP single and dual speed models.
  • Hayward Northstar SP4000 Series Pumps (1998-2002)

Tune Up Kit Includes:

  • Diffuser Gasket
  • Pump Lid O-Ring Pre-2003
  • Housing Gasket
  • Motor Shaft Seal
  • Lubricant
  • *The Pump Lid O-Ring Pre-2003 is the only part that is different in this kit. All other parts will fit the Hayward Northstar 1998 to 2007.

I recently changed my pool motor and gaskets. I made sure to lubricate all the gaskets with vaseline. A few days later water is leaking from the pump. What did I do wrong? Help please!!

A  Answered on 2/13/2012 by InyoPools Product Specialist Patrick P.

You never want to use vaseline on any rubber gaskets or o-rings. Vaseline is petroleum based and will deteriorate the rubber quickly. Whenever you change the motor on a pool pump it is recommended that you replace the gaskets and shaft seal as well. A >Go-kit contains the shaft seal, packet of non-petroleum based lubricant and gaskets you will need for your pump. If you already have the gaskets, you can purchase >Magic Lube.

My pump is not priming even after cleaning impeller. Will purchasing this kit aid in fixing that problem?

A  Answered on 10/15/2014 by InyoPools Product Specialist Patrick P.

The seal kit can help with loss of prime. I can't guarantee that it will solve your problem. The loss of prime could be from an air leak at the valves or plumbing in front of the pump.

how do I know if sp4020x252ns is pre-2003 pump. I have the serial #62CB33

A  Answered on 5/5/2016 by InyoPools Product Specialist Charlie R.

Bill,Unfortunately, only the manufacturer has access to serial number information that can usually tell you things like what year the pump was made. If you are unsure about your pump, we recommend getting in direct contact with Hayward at 888.429.9273

Does this kit include the union O-rings?

A  Answered on 5/28/2016 by InyoPools Product Specialist Joe S.

Hello, it comes with one diffuser oring which can be used as a union oring. You can purchase them under part Oring, Union & Diffuser (spx4000z1).

I have a Hayward Northstar sp4010ns pump, not sure if it is pre- 2003 or not as the pool was installed in early 2004. Would this seal kit work?

A  Answered on 2/6/2017 by InyoPools Product Specialist Scott W.

Yes, the GOKIT66 would be the correct seal kit for the Northstar before 2007.
