Backplate Kit - R0445200
This back plate is designed to use with Zodiac Jandy ePump, Stealth, PlusHP, WaterFall, MaxHP series pumps models JEP, SHPF/SHPM, PHPF/PHPM, SWF, MHPM.
My back plate is in perfect condition with exception to the 2 brass female threaded inserted are missing. They are needed for screwing the defuser to it. Instead of buying a new back plate can I just use long stainless steel screws and threading it into the composite material of the back plate? Or can just not use screws?
I wouldn't screw into the material it may crack and leak. The diffuser just needs to be held in. If you still have screw holes that are staggered it will be fine.
I have a jandy jhpu pump assembly i cannot get a new base because they are no longer available.Can i use my existing motor on a new pump shpf assembly
Those two pump models have motors with different frame sizes, one being round flange and the other being square flange, so it will not work.
Does the Backplate Kit come with the shaft seal and the o-ring as shown in the picture? There is no description in the "details" section. Thanks
My SHPM1.5 pump started leaking near the backplate and the electric motor. I assume it is the two shaft seals. Would I be correct most likely?
Most commonly this does describe a shaft seal failure. Especially if the leak is specifically coming from the back of the plate where the shaft seal is located. You may want to double check the plate for any hairline cracks as well.
Jandy Stealth Pump, Model# JHPU1.5
There is a crack on the Backplate of the pump (Model# JHPU1.5).
But the photo of your part# R0445200 does NOT look exactly to the one in my pump.
(I ordered a service kit of "Tune Up Kit Jandy JHP + JHPU Series Pump", item# "GOKIT77"). The Gasket does fit).
Need some recommendation from you on the Backplate.

This the prone part of this pump the treads for the bolts that holds the diffuser into the backplate they corrode and will not hold the diffuser anymore. The reality the first problem are the shaft seal that will first affect the motor, and that happen in 7 years. To replace the motor and seals, you have to remove the diffuser by removing the screws that hold them into the back plate. When try to remove those screw one broke due to corrosion, had to cut to be able to remove. Removed the impeller and seals and replaced the motor and placed the new seals. Had to use a screw a little bigger to be able to hold the diffuser into the back plate.
During a period of 1 1/2 year the diffuser got loose twice and it is pushed against the basket and it is kind hard to remove.
If I knew all of this before, I was going to do a preventive maintenance in about 5 years. And at that time, replace the seals, but not just the seals, I was going to replace the backplate as well that include the shaft seals, mainly because the treaded hole to hold the diffuser. If I knew this before it was going to save me of a lot of headaches.
The main problem is the pool not running for few days waiting for parts in hot weather, the pool get nasty quickly.

1. Ensure power is cut off to unit at both panels
2. Disconnect power lead to old motor
3. Remove bolts that connect back plate with motor still attached and pull from the pump housing
4. Once these bolts are removed you can lift the entire unit (motor and back plate) out and then disassemble motor (4 bolts I think) from motor to back plate.
5. Remove the diffuser which allows access to impeller and remove 1 stainless steel bolt in center
6. Now you can remove the impeller that will allow access to motor mechanical shaft seal
7) With back place off and impeller removed replace new seals and reverse order 8) Main thing to look out for when replacing this is to not tighten up any screws initially in order to make sure the bolt holes and threaded portion on the pump housing are aligned properly and then once so tighten in a star pattern to ensure even mating and torque
