My friend and I both picked up Eryx's last month and both of us have had a bearing fail on the middle shaft that holds the spur and belt pulleys.
My friends bearing went out on him on the first day of driving it and mine went a week or 2 after that. Both bearing failures resulted in the middle shaft needing to be replaced due to damage on the ends where the bearing fits on too. We both run Mod class, 4.5T motors.
Im just curious are other guys(especially mod) having any similar problems?
one thing I noticed when ordering new bearings is that when searching for replacement bearings using the Serpent part number is that a flanged bearing comes up. Both our kits came with standard non flanged bearings.
Could this help explain the bearing failures? and maybe explain the spur side play that I see most people on here have?
I ordered the flanged bearings and also have some non flanged bearings like the ones that came with the kit. im waiting for them to come in along with the new center shaft. Any advice on which style bearing to use? we really don't want to keep replacing center shafts.
Yes, over the course of all the S cars I have had I have had two bearing failures on the center shaft. Both times it has been on the motor side which I think takes the most stress. The secong bearing actually blew out but I didn't notice it immediately which in turn destroyed the shaft. I think the bearing seized so the shaft was rotating in a more bushing type state, which ended up messing it all up. I haven't had a issue since, but I also make sure that those two bearings get oiled regularily. I also have mentioned this to Serpent to consider upping that particular bearing size just so it can take the load better. The bearing itself is not flanged, and I think if you use a flanged bearing on both sides it will not fit properly between the two mounts, speculation on my part though.
