rear wheel bearing

[coffy]

Hi, just wondering if anybody can help with my question, I have had the rear wheel bearings pressed out of wheel by a machinist, but problem i have now is that i need to know which way the needle roller bearing which press's into the left drive side of hub, as one end of bearing has a seal built into it, i asked machinist which way it came out when pressed, he not sure as a staff member in workshop did it, so does seal face in or does it face out, I might add that there is also a seal theat press's in after seal,

all help appreciated

Thinking I am reading this correctly Coffy,,, never owned an RSTD but cant imagine it any different than most wheel bearing applications. You want to end up being able to apply fresh grease into the open side of the bearing if its not a totally sealed unit.. If there is a seal that is pressed into the bearing journal after the bearing is pressed in (which - if my memory is correct - this is exactly the case on the 83's I have serviced bearings on - cant be much different than yours) it is that seal that seals the side of the bearing that is open. It is also that seal that allows you to repack that bearing with grease during maintenance intervals. All that said = the bearing face with the built in retainer/seal would go internal.. In the end you should end up with open face of the bearings pointed outwardly and having those open faces covered by the rubber seal you would place in after the bearing is installed.. The built in seal factory installed into the bearings would keep grease from running into the area in the center of the wheel and thereby ending up with dry bearings. Dont forget to install ALL internal spacers before you press the bearings in, there should be an internal spacer that - as the nut is tightened on the end of the axle it ultimately is captured against bushings and bearing races and not pulling the bearings inwardly on their races - make sense? I am hard to follow sometimes so it may not!!

Also, I like to pack the open bearing faces behind the seals really well after installing the bearings and seals before I slide the axle thru. Its a really good practice to make sure the seal lips that meet the axle are also lightly covered IMHO. Light smear on the axe itself dont hurt.. Also, dont forget to grease the buffer pins and splines - saves a lot of wear n tear - keeps things quiet too..
