Product Description

Standard tune up kit for the Pentair Challenger 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 Pentair & Pac-Fab Challenger Pumps 1/2 HP - 3 HP single and dual speed models.

Tune Up Kit Includes:

  • Motor Shaft Seal
  • Pump Lid O-Ring
  • Housing Gasket (round gasket, if square gasket is needed you must order it separately)
  • Diffuser Gasket (round gasket, if square gasket is needed you must order it separately)
  • Lubricant

For more Pool Pump Motors

I have the PAC FAB Challenger. Do I need GoKit 5 or GoKit 73?

A     Answered on 2/9/2017 by Hector F.

They GOKIT73 has the squared off diffuser gasket at the cross section and the GOKIT5 has all o rings and gaskets that are rounded at the cross section. Technically there are two Challenger kits.

What I can read is PAC-FAB 2 HP and then ABEL 35-546. On the inside, on the inside of the back plate there are numbers: 35-5303 (3 inserts) and 35-5497 (6 inserts). Question: what GO-Kit do I get? It was attached to a 2 HP motor.

I have a AO Smith UST 1152 Pool Pump Motor with a Challenger pump: Model CH11-N1-3/4A attached. The motor runs, but the pump is not working. Do you recommend the Tune Up Kit Pentair Challenger Pump - GOKIT5 or something else?

A     Answered on 10/26/2016 by Lennox H.

Hi, Douglas. It depends on what is causing the pump not to pump water. Once you determine the cause we can assist you with resolving the issue. You can use our 8 Answers to “Why Is My Pool Pump Not Working?” Blog to assist you with figuring out why your pump isn't working.

I have a 2hp PAC -FAB pump is 20 yrs.old , I replaced thr motor 3 yrs. ago put new impellar in this year can not find any leaks all lines are clear . It will not pull water from skimmer that is fartherish from pump can not get good volumn at discharge . Strainer will not completely fill get air in filter .

A     Answered on 8/31/2016 by Scott W.

It might be the wrong impeller that you have. They have a medium head and high head impeller. If you happened to purchase the wrong impeller to match up with your diffuser and motor than that would be the problem with why it's not pulling the water.

I have a 2hp pac fab pump, I can not get the bubbles out of the strainer so the filter gets air in it , I can not get a good suction and do not have very good volume of water . I replaced impeller and defuser but not much help new motor .Pump is 20 years old.

A     Answered on 8/30/2016 by Scott W.

I apologize for the delayed response. You have an air leak somewhere whether it's the seals in the pump that are bad or a leak in the plumbing.

A     Answered on 6/18/2016 by Lennox H.

Hi, The bearings are going bad in the motor, you can either replace the bearings or the entire motor.

Hi. I have a Pentair-Model # CHII-N1-1A/346204. It was making a really loud noise, so I replaced the bearings. It is really quiet now, but now it is leaking a lot of water. What seals would I need to replace. The large seal is square. Thank you for your help. Renee

A     Answered on 6/12/2016 by Patrick P.

Hi Renee, We would suggest this tune up kit and replace all the gaskets and o-rings that are included in this kit. It is most like the spring loaded shaft seal that is causing the problem.

Yes, this is the correct tune up kit for your Pac-Fab Challenger 1.5 hp model CH11-N2-1.5A.

?     Asked on 6/5/2016 by Eric weber

How do identify if my challenger motor is greater than 3hp. The labels are a little bleached. My pool is small and only 6ft deep so I doubt I have a larger engine. Not sure. Thanks

A     Answered on 6/5/2016 by Alan M.

Hello Eric, There is a minuscule chance that your motor on your pool, less than 40,000 gallons is 3HP or greater. There is no real way to determine the size of your motor from a label that has faded or by visually inspecting the motor. You can take dimensions of your pool, filter size, pipe size, and attached features (spa, solar panels) and factor that information into determining a motor size. We would also recommend changing the seal on your pump when changing the motor.

?     Asked on 5/5/2016 by Joseph

will this kit fit my Centurion (A.O.smith) 1 HP B853 model?

A     Answered on 5/5/2016 by Hector F.

As long as you have the Challenger pump then yet this kit will work. Please keep in mind that some of the Challenger models have the housing and diffuser gaskets squared from a cross section perspective and those style gaskets are sold separately.

?     Asked on 9/16/2015 by Michael

Salt water and regular seals: what's the difference other than price? Could this be why the bearings in my existing motor failed? Is there a way to tell if the existing seals in my other motors are salt water or not? If they are not should I replace them on the working motors? Can I get a kit containing the salt water parts? Do I need to? Why isn't this more prominently advertised? I just about bought the kit and if I hadn't read the comments maybe it would have been a big mistake?

A     Answered on 9/17/2015 by Andy O.

Michael, The only difference between the standard and salt water kits is that the shaft seal is made  with VITON instead of standard rubber. Viton can withstand harsh minerals better than the standard rubber seals. There is no saltwater tune up kit for the challenger yet, but we do offer the salt water shaft seal. The bearings on your motor failed more than likely because your shaft seal did at one point. These salt water seals are so new manufacturer's don't even offer them yet.

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 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.

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 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.

 (4 out of 5 stars)  Nice Tune-up Kit

from Fairfax, VA ()

Pros: Multiple sized strainer pot o-rings ensured the proper fit.

Cons: Having to make a separate order for the correct diffuser ring.

I ordered this kit mainly to replace the diffuser o-ring which was badly worn. It turned out that the diffuser needed the square ring gasket instead and it wasn't included, just a normal o-ring which wasn't the correct one for my Challenger pump. I will have to make a seperate order for that. However I used the other parts just fine and am happy with their performance.

from Plano, TX ()

I made the right decision to order GO KIT 5 when I was replacing my pool pump motor. Shaft seal and all other O rings worked well. I wish that there is some explanation on "Gasket" vs " O Ring". I did not know that both mean the same.

This kit had all that I needed to work the pump/motor. Was just going to get a mechanical seal, but for the entire package, I was able to replace all gaskets also.
