Leopard 5692 bearings

[ray schrauwen]

Well the bearing going bad could be related to shaft flex - or not. The issues with the Neu were real and prompted Neu to redisign the motors - would they have done that if there wasn't a problem. Yes, a 6mm shaft is 30% stronger than a 5mm one, it may be strong enough. But you could be having flex problems now and just not know it - not until a winding shorts out.

But it appears that Leopard realized the potential problem, otherwise why would they change to the 8mm shaft? The cost difference between 6mm and 8mm shafts and bearings matters to Chinese companies trying to hold down costs. I hope the current motors work well for you, they may do fine. Me, I'd hold out for 8mms.

I don't know if they realized any problem. Maybe Chris Fine and his purchase of a lot of motors with 8mm shaft got them thinking, why?
Who says they will be the same price?

Who knows....

Before any conclusions are jumped to, we can still get them in 6mm shaft sizes.

How the hell am I going to "hold out" for the 8mm shafts when I have been using the 6mm shaft motors for nearly 2 months?

I got them from Steven at OSE, are you saying he sold me faulty motors? Hey Steven, why did you sell me the puny 6mm shaft motors? I think you should instantly send me the new 8mm shaft motors so my boat doesn't blow up.

Sounds like how the auto companies make changes in their cars to improve something. I guess everyone that buys a new car just prior to an improvement should have "held out" for the new version.

Again......

I got the bearings from Boca Bearings today. They were super easy to install. The total time once I got the motor out of the boat was about 10 minutes to change the bearings. The motors are super smooth and quiet again.

For future reference the Boca Bearing part number for Leopard 5692 1340 KV with 6mm shaft is SMR626-ZZ.

I would like to ask how the motors are doing with the new bearings? Thanks.

So apart from the bearings quality, is there a design issue?

[TotalPackage]

same question i have . I mean the keep callin them neus but i doint remember anyone reportin nue bearing prematurely failing new like this turns me off coz i waz about to buy a 5692 keep me posted

[ScarabChris]

Aside from the bearings going bad in one of the two motors they have been flawless. Tons of power. They are now pushing the boat just over 60 MPH and the RTR weight is just shy of 30 pounds.

I just think they used super cheap bearings from factory. Just looking at the Boca bearings compared to the stock bearings I could tell the Boca's were of much better quality.

The end bell comes right off and the bearings come right out with a slight tap with a wooden dowel.

The TOP POWER 1380KV motor has some additional glue to deal with...
