the electrical erosion

Scrape Backing bearings journal and the cavity of the old grease, wash with detergent and the journal bearing and dry with a cloth, and finally wipe with a cloth interior.
    Check the bearings and bearing races and found that there are cracks, fatigue spalling and loose roller bearings and other phenomena, replace bearings. If you find that there are bearing race pitting should also replace the bearings.
    Check LNSERTED journal bearing bore and cope with the situation, with the gap should be less than 0.10mm measurement journal, should be in the upper and lower parts of the vertical ground (where the largest wear parts) measurements. If used with the gap exceeds the specified limit, replace the bearings, so back to normal with the gap. Not allowed in the journal deburring, pitting to narrow the gap.
    After all parts are in line with the requirements, the inner bearing grease after the release of people.
The LNSERTED bearing grease chamber should pay attention, you should squeeze bearing grease until the grease from the bearing on the other side coming out so far. Intracranial axis in the cavity and apply a thin layer of grease to make it play a role in anti-rust. Note Do not apply grease cavity too much, otherwise it will affect the cooling and braking.
    The journal and the outer bearings mounted back on the hand shaft adjustment nut, and then use the required shaft torque wrench tighten the adjusting nut. Tighten the nuts, you should turn around a few times to see if the bearing installation; the other hand, by turning the bearing and seat properly fit. At this time bearing tightness appropriate wheels to rotate freely and not feel the axial clearance.
    Finally in turn mounted locking plate, nut, tires, dust cover and decorative cover other pieces.
    LNSERTED bearings adjusted, travel for a distance (10km or so), stop and check for swab touch temperature, if fever, caused by the bearing adjustment too tight, should be re-adjusted, appropriate to relax the bearing tightness.
