Nissan Sentra Service Manual: Replacement operations
Description
This section is prepared for technicians who have attained a high level of
skill and experience in repairing collision-
damaged vehicles and also use modern service tools and equipment. Persons
unfamiliar with body
repair techniques should not attempt to repair collision-damaged vehicles by
using this section.
Technicians are also encouraged to read Body Repair Manual (Fundamentals) in
order to ensure that the original
functions and quality of the vehicle can be maintained. The Body Repair Manual
(Fundamentals) contains
additional information, including cautions and warning, that are not including
in this manual. Technicians
should refer to both manuals to ensure proper repairs.
Please note that these information are prepared for worldwide usage, and as
such, certain procedures might
not apply in some regions or countries.
The symbols used in this section for cutting and welding/brazing operations
are shown below.
- Front pillar butt joint can be determined anywhere within shaded
area as shown in the figure. The best location for the butt joint is at
position A due to the construction of the vehicle. Refer to the front
pillar section.
- Determine cutting position and record distance from the locating
indent. Use this distance when cutting the service part. Cut outer
front pillar over 60 mm above inner front pillar cut position.
- Prepare a cutting jig to make outer pillar easier to cut. Also, this
will
permit service part to be accurately cut at joint position.
- An example of cutting operation using a cutting jig is as follows.
- Mark cutting lines.
- Cut position of outer pillar
- Cut position of inner pillar
- Align cutting line with notch on jig. Clamp jig to pillar.
- Cut outer pillar along groove of jig. (At position A)
