Remove the door button carrier T0513 from the door handle mechanism
T0511 by removing the 2mm split pin and fit the joggle through the hole
provided. Refit the door button carrier to the door handle mechanism and
check that everything works effectively. It is extremely important that there is
no excessive play in the mechanism and it is worth at this stage taking some
time to ensure the correct operation. When completely satisfied spray out the
ends of the split pin. The door latch and the door lock should now work
satisfactorily. Provision has been made for a strip spring to be used between
the door button carrier and the door lock mechanism that in practise has been
found to be unnecessary.
Fitting the Frame
Fit the door frame complete with glass to the door. Mark the centre of the four
recessed inner frame mounting points and pilot drill. Open out with a Ø6mm
clearance drill. It is necessary to extend the outer glass line on the door shells
to enable the glass to wind up and down. A split line on the mould indicates
the line of the outer glass. This shows up as a raised line on the shell of the
door. Extend the rear line to within 3mm of the end of the door and form a slot
for the glass to wind up through, 10mm wide. Do this work very carefully as it
shows on the exterior of the car. Where the glass runs up into the small
triangular panel at the front of door on which the wing mirror mounts, it is
necessary to trim the moulding in a similar manner to the rear edge of the
door. Use the mould line as a guide and open up the slot to 10mm, as at the
rear. The glass must run as far up into the triangular panel as possible to
minimise the difficult condition with the door seals when shut on the car. As
with the rear, do this work carefully as it will be seen when the car is complete.
Prior to fitting the door glass weather seal T0517, it is advisable to fit the door
inner frame complete with glass to the door using the 6mm stainless steel
counter sunk screws and washers. Check that the window winds up and
down freely and that the glass has a clearance between the outer door and
the outer face of the glass particularly where the weather seal will fit.
Adjustment can be made to the fitting of the glass by inserting washers
between the doorframe and the door outer skin. Once this seems
satisfactory, remove the frame.
Trim the door glass weather seal T0517 so that it is the correct length from the
back face of the door to the small triangular wing mirror panel. Clean the
inner face of the door shell and lightly sand the inner face on which the door
weather seal is to be glued. Glue the door glass weather seal T0517 to the
door shell T0104/5 using “super glue”.
Door Mirror Assembly
The two mounting storks approximately Ø10.5mm have to be shortened on the
standard Rover K Series mirror to a length of approximately 13mm from the
outside inner face of the mounting flange. These can be easily cut with a
junior hacksaw. Open out the inner hole in these mounting tubes from 5.2mm
to a depth of 15mm. Tap these holes, Ø6mm metric fine using a standard
metal tap. Check the thread by screwing in a standard Ø6mm bolt.
