Maxspect Gyre: Step-by-Step Assembly & Advanced Troubleshooting
I n this episode of [CVtv], Carlos Chacon takes you step-by-step on how to properly assemble the Maxspect Gyre pump and covers some advanced troubleshooting.
To assemble the gyre, we must make sure that all motor block bushings are installed correctly. Although the bushings are usually preassembled and installed, here is a picture of what they look like just in case you took them apart for cleaning.
Take the magnet/shaft and carefully insert it into the motor block. Now take the star bushing and with the flat side facing in, push the bushing in place into the motor block. Now the magnet/shaft is secure and the motor block is fully assembled.
The next step is to install the propellers. First we need to ensure that all the propeller bushings are installed. The propellers have two bushings. There is a black rubber grommet that gets inserted into the end of the propeller and then there is a small hard bushing that gets carefully inserted into the rubber grommet.
For those of you that are just swapping dirty propeller for the spare set included with your pump, just make sure that you transfer any missing bushings from the previously installed propellers to the replacement ones.
Now, some propellers are labeled which make the installation rather easy but there are some that are not. So in order to know which propeller goes on which side, we must first determine the type of propellers we have.
The gyre comes installed with an A propeller on the left side and a B propeller on the right side. If you notice, the individual blades on each propeller are angled so the front of the blade always faces the front of the pump. You will also notice that the propellers come with a small white shaft attached to them. If you have a propeller with the blades facing you and the small white shaft is on the left, then you have a propeller A. If the blades are facing you but the white shaft is on the right, then you have a propeller B.
Assuming that you will only be using the pump in forward motion, install the A propeller on the left and the B propeller on the right. If you are thinking of running the pump in Alternating Gyre Mode, please check out our “Alternating Gyre Mode” video where we show you how to properly configure the propellers on the pump so it is capable of running in both forward and reverse motion.
As you install the propeller to the shaft, you will notice that the shaft has a flat side with a matching key on the propeller bushing. This allows the propeller to properly grip the shaft and spin. If the shaft and the propeller bushing are not lined up, the propeller will not be able to grip the shaft and will slip.
Before we install the cages, it is best to test the integrity of the propeller bushings. Over time the bushings will wear and may even strip. These will cause the pump to not work correctly. Since the pump comes only with a single shaft that goes from side to side, both propellers will mirror each other. This means that the propellers cannot move individually or in separate directions. If they do, that means the propeller is not installed correctly or the propeller bushings are striped and will need to be replaced.
Similar to the motor block, the directional cages come with a preinstalled set of bushings. If you are cleaning or replacing the cages, be sure to reinstall the bushings before attaching the cages to the motor block. If for some reason the cage bushings have been lost of damaged, your pump came with a spare set of replacements.
Just like the propellers, there are two types of cages. Locate cage A and carefully insert it onto the left side of the pump with the matching propeller A. Be sure to line up the propeller outer shaft so that the cage bushings are not pushed out when inserting the cage. Repeat the process when installing cage B.
We are almost there. The last step is to install the suspension mounts. Be sure that the suspension mount bushing is in place before installing the suspension bracket. To install the bracket, simply line up the connection points and push it into place.
Now, here are some issues that can be easily solved by just correctly assembling the gyre pump.
My gyre pump is running but only one side of the pump spins. What should I do?
Check to make sure that the propellers have the complete bushing set installed. If you are using spare propellers, make sure you transferred all bushings from the previously installed propellers. Also check that the flat side of the shaft is aligned with the small black bushing and ensure that the bushings are not stripped.
My gyre is running but it is not pushing any water. What can I do?
Make sure that you have the correct propellers and corresponding cages installed. Remember that the gyre needs an A propeller and cage on the left and a B propeller and cage on the right.
My gyre works fine but it just does not push as much water as it used to. What could it be?
To obtain optimal performance and long life, the gyre needs to be cleaned on a regular basis. This means taking the pump completely apart, cleaning or swapping the propellers and the cages and inspecting all wearable components.
My gyre randomly flashes a red light. What is wrong with it?
Please remove the pump and completely disassemble it. Make sure that all components are clean and in good working condition and then assemble the pump again following the instructions at the beginning of this video.
