Not on the maxx pumps with maxx driveshafts. All of the maxx driveshafts i have seen use the std single row oem style bearings. Different than skat seback setup. I have a maxx shaft here from tricky for testing and we will be setting up josh's maxx pump with a mag shaft like skat with the dbl row bearing in front. In my opinion, the dbl row bearing is needed for stability when you move the bearings closer together.

so do i need another oem bearing or a different one to do the double row?

The OEM bearing is a 6205 which is 25x52x15 (mm's)
The double row bearing used in Skat setback pumps is a 5205 which is 25x52x20.6 (mm's)

The difference is only 5.6 mm's (0.220472")

How long has maxx been making his pumps? All of the TIG welds on his pumps are fused (electrode melts both parent metals to form a weld bead without the addition of filler material and creates a concave shape weld, good for 3mm parent material tickness or less), fused is good for looks and for sealing edges etc, but has a dramtically reduced amount of strength in sections greater than 3mm therefore would make them prone to cracking. These pumps cop a heap of vibration and erractic loading so I'm interested to har if anyone has had the mounts crack? would be easy to fix, just run over the mounts again adding filler.

I guess fuse welding the stainless together helps with keeping the cost down and productivity up.

Only time will tell how well these things will hold up.

Does this guy offer any kind of warranty on these pumps if they happen fall apart?

I've had mine in my vision for about 6 months now without any issues except for the driveshaft being soft and bending slightly. I've since then replaced it with an OEM yamaha modified couch driveshaft

We had issue with the first batch of pump from maxx as one of us is riding in a place which is extremely salty... and wether you flush or not... salt will go everywhere and make a mess...

Maxx did offer replacement on warranty so he is good on that, and that was very much appreciated as customer service, so thumbs up for maxx

but I agree let's see how those new ones last in time.... as we all know skat pump last forever...

skat is crap. the stator veins on it are fuse welded. every skat pump i've touched now has had way different bearing tolerances. from being able to drop a bearing in with out a press to needing slightly hone it out. i think maxxx has a very solid piece. i don't see why his pump would last any less time then skat.

the sbt vs cf shaft deal. i think the cold fusion shaft was the hardest metal of all the shafts on the market. if you had to pick something that would wear over the other would you pick the driveshaft or midshaft? midshaft is way cheaper to replace in my opinion. like Jetmaniac said. All of is big motor FL guys ran sbt with no issues.

didnt ask about warranty......



I wish he would make a SS reduction nozzle as well with a monster exit.....maybe someday

Also inserts /along rings that let you play around with the exit size. You could really dial in your pump easy that way. Dont some couch racers have a set up like this.

Hybrid ceramic . I use them in the carbon fiber wheels in 2 R6 sportbikes . The front wheel will spin for over 6 minutes without stopping while bike is on stand . Stock bearings the wheel goes about 6 revolutions before stopping . That is what convinced me about hybrid ceramic bearings . I have them in pumps and midhousings in 3 standups .

I did some looking today for my pump thats on the way... www.bocabearings.com Has the hybrid ceramic bearings for the Kawi pump at 55.00 each. I searched by dimension and scrolled down until I found the hybrid bearing. There is a full ceramic as well at 155.00 each.

Full Ceramic wont work Hybrid uses steel races with ceramic balls . The balls are harder than steel and do not wear out . Bearings can be rebuilt using balls from previous bearing . If you are not carefull installing and beat on it the wrong way the races can be dented , like any bearing .
