Welding
Always disconnect the battery, and remember this
point: Attach the negative terminal (-) of the welder
to the part you are welding (+). This is to avoid
having a high current flowing through parts like
bearings and damaging them.
When you are mounting retainers, always use
the right tool for the job.
This will make sure the part is mounted in the correct
position and undamaged. Otherwise, it may start to
leak after just a few hours of operation. In addition,
make sure that the seat of the retainer is clean.
Lubricate the lip of the retainer. Take special care
when the retainer passes over a splined axle, a
keyway, etc. The slightest cut on the lip will cause
leaks.
Removal and fitting of bearings
To remove bearings, use proper extractors.
It’s important that the extractor be supported on the
race that is fit with interference, thus avoiding
damage to balls and rollers.
When assembling:
-
Never hit a bearing directly with a hammer. Use
a suitable tool with a cup shape, or similar.
- When mounting a bearing on an axle, press on
the inner race; when mounting a bearing in a
hole, press on the outer race.
