The bearings used are two 6003r's they are 17mm Id 35mm od 10mm depth, there's no wear at all in them so they seem more than upto the job, the laminations are not that thin I didn't measure but I'd estimate theres around 30 1mm sheets and it's a one piece design no alloy centre for heatsink just an axle with a lipped outer to align properly then a drift key to secure it
Main thing is they all work fine and after a refurb they will be better than new and perfect for my needs, Powerwise I'd say they look comparable to a my1016 brushed motor so 800w area will be max continously I'll get away with so I'm ordering 4, 48v 500w 30a controllers 12 fet with reverse that will give me upto 1.3kw bursts in max power mode so it will be over 5kw on max.
I checked the battery box and it's perfect for the 48v 20ah or 24 10ah cells I got so I can see this being quite some fun and a decent range too stock it had 24v 20ah of lead so Ive doubled my capacity and in the real world trippled the range.
I'll even keep the reverse beeper this thing has to be stock looking as can be for it to be a true sleeper wolf amongst sheep, it's not going to brake any speed records but I think with four motor's it will go anywhere
I got the motors and opened them up to check them over and the design is OK and build quality is so so, there's a lock washer on one motor not on the other three and the windings on two have all the insulator sleeves on the other two are missing all the outers.
