Soft Top Installation


For those of you that have great manual dexterity, lots of patience and are

truly  crazy do-it-your-selfers I post this method of top installation. For

those of you that are not so inclined I include the same instructions at no

extra  cost as you may wish to supply these to the upholstery shop that you

choose  to  install  your top. I do not profess to be a qualified upholster

but  I  do have some knowledge as my sister owns a upholstery shop. She did

not  help  with this installation but I used the principals that she taught

me. I INSTALLED a Robins top PURCHASED FROM CAT.


This may or may not be the correct way to install TIGER "weather equipment"
but it did work for me. YOU TAKE YOUR CHANCES IF YOU FOLLOW THIS!

READ  this ALL BEFORE you start. The entire top may be fitted with glue and
duct  tape  to ensure that you know what you are doing BEFORE you punch any
holes. Practice FIRST.

Sandblast  and  paint  the  top-bows  or  finish them by industrial plating
before you start.

1.  Adjust the tension rods. (See following)

2.  Adjust the Top-bow webbing (see following)

3.  Ensure that the Top-bow pivots (on the top of the B posts) are adjusted
    and  function  perfectly.  Check  that the top-bow side-window surround
    fits  the side windows when they are in the up position. The thin metal
    pieces  that  the  top  pivots on are the most delicate part of the top
    assembly.  If  they  are bent the top will not fit the side windows. If
    1,2,3  are  not  done  properly you will never get the top to fit. Your
    side  glass  must also be correctly adjusted in the door to ensure that
    they do not lean too far in or out.

4.   Place  the  new top over the top-bows. Align the front cross seam over
    the non-folding, front top-bow. The rear cross seam should line up over
    the rear, folding, cross-bow if the top-bow web is correctly fitted.

5.   The  vertical seam at the rear of the side window openings should line
    up with the vertical post of the top bow. The seam at the bottom of the
    top  should  touch  the body of the car on both sides at this point. If
    not, center the top.

6.   Replace  the Velcro on the top bow stays if required. Use book binders
    tape  or  duct  tape to hold the hood on to the Velcro (Remember Velcro
    sticks best if it is rubbed down several times). Do not leave this tape
    on for more than a few hours or the glue will mark the top

7.   Tape  the  Top-bow-to-Windscreen rubber to the top of the windscreen..
    Now tape the top to the chrome of the wind screen surround.

8.  Use GEL TYPE contact cement on the top-bow uprights and then on the top
    to  glue  the vertical seam to the upright. GEL contact cement will not
    melt  the  plastic that the top is made of. It also will not string out
    and  get  all over everything and it will clean off. Let both sides dry
    and then make contact. Do not bunch holes for the screws that hold this
    area on to the top bows at this time. It is essential, though, that the
    top be tight from side to side, over the top bows.

9.   Brush  contact  cement  on  the rear cockpit cowling and on the rubber
    edging  that  finishes  the cockpit. Attach the edging to the car after
    both  surfaces are dry. If the rubber trim is new use a white marker on
    the  rubber  to pin point the screw holes in the rear cowling metal. If
    you  are  re-using  the  rubber, line the screw holes up with the screw
    holes  in  the  metal.  You may now put a screw in each end of the rear
    trim, pulling gently outwards form center on each side.

10. From inside the car pull the rear of the hood back - at the center (not
    too hard as it is better to be loose than too tight). Locate the center
    hole  in  the  aluminum  trim and screw through it and the top into the
    center  screw  hole  in  the rear cowl. this is the first hole that you
    will put into the new hood and your stomach will tie into knots here.

11.  Check that the hood fits correctly at the back. The flap that contains
    the  snap  and  the  "Lift-a-dot" must fit flat on to the car body. The
    rear  edge  of this flap, were it is sewn to the hood, should just meet
    the car body.

12. Check the fit over the cross bows. It should be tight. Install the lift
    a dot on each side now.

13.  Install the rear snap pulling gently back on the flap against the lift
    a dot. If your top is properly installed you will not have to pull down
    only  back.  This  is the secret to having a properly fitting TIGER top
    with no wrinkles in the side panels.

14.  Now  go  back  to  the  inside  rear and begin working from the center
    outward  on alternate sides, screwing the rear trim to the body. As you
    do  this  pull  gently down and away from center. Remember that you are
    only pulling against the binders tape at the front. You may pull harder
    towards  the  sides as this must be a good fit for the top to be tight.
    Check  the  outside  fit  as you put in each screw. Be sure to see that
    your tape has not pulled free at the front. You do not want wrinkles to
    develop either.

    DO NOT screw the inside shorter side trim on at this time.

15.  Now  work  on the leading edge. Pull the top tight and re-tape working
    from  the center outward to each side. Run long pieces of tape from the
    hood  down  to the windscreen. Now mark the top with masking tape where
    it  crosses  the leading edge of the peak rail. Also mark the center of
    the  top  with  masking tape and with a second piece mark the center of
    the  peak  rail. You will have to remove some of the binders tape to do
    this.

16.   Now  unsnap  the top clamps that hold the peak rail to the windscreen
    remove  all the binders tape and fold the tension rods upwards. At this
    point  you may want to tape the side stays into their retaining pins so
    that  the whole thing does not collapse on you. Spread GEL TYPE contact
    cement  on the underside leading edge of the peak rail and on the front
    1 inch of the underside of the top. Be sure to cover the top with paper
    before  you  do  this  so that you do not get any  glue on it. Let this
    dry. Now attach the top to the peak rail starting at the point that you
    marked  as center. The masking tape that you marked the leading edge of
    the  peak rail should just roll under the peak rail leading edge. Press
    the  glued  top  edge  into  place working from the center outwards and
    pulling tight as you go. Be sure to work the top well up into the under
    side curve of the peal rail.

17.   You  may  now  snap  the  peak rail back onto the windscreen. The top
    should  at  this  point be a snug fit with no wrinkles nor loose spots.
    You may adjust the fit at the front by repeating step 16.

18.  Adjust  the fit at the sides by repeating step 8 if required. Wind the
    side  windows  up  and make sure that they fit. The screws and trim may
    now be installed on the uprights.

19.  The  back  fit  may  be  adjusted by removing the rear trim screws and
    pulling  downwards  and from side to side in order to take up any slack
    or  to eliminate any wrinkles. Remember I said in #10 that it is better
    to  be  slack here than to be too tight. NOW is the time to take up the
    slack.  Any  holes  previously  punched in the back  edge will be lower
    than  the new holes and will not cause a problem. You may find that all
    fits  well  and  no further adjustment is necessary. I mostly give this
    caution  so  that you do not pull too hard in step #10 and pull the top
    out of position.

20.  At  this  point you can now let the work rest a while. Let the car get
    cold in the evening. Let the sun shine on it. Drive it a bit. I put 300
    miles  on my Tiger in pouring rain and the front glue held but I do not
    recommend this as a test.

21.                                                           Once  you are
    sure  of  the  fit  remove  the  rubber that you taped on to top of the
    windscreen and install it onto the bottom side of the peak-rail.

22.  Now  all  that  remains is to secure the short side trim to the rubber
    trim that finishes the cockpit. This trim does not hold the top it only
    holds  the  rubber in place. Remember that the top in this area must be
    slack  for  the  top to fold down when it is finished. The piece of the
    top  that  hangs  down is simply held to the edge of the car by a clip.
    Several  "alligator clips with the handles removed can be used for this
    of the originals are missing.

          This   is  the  area  that  most  people  including  professional
    upholsters  screw  up. It seems logical to pull the top tight under the
    short  trim  pieces  and screw it down. You will find that the top will
    not  fold if you do this and you end up with unwanted holes in the top.
    The purpose of these flaps is to guide the water that leaks in into the
    drain holes behind the B pillar. Be sure these drain holes are clear.

Top Bows


The  top bows of a Tiger are strange things indeed. Their stability depends

upon two blocks of plastic holding two thin rods from moving laterally. The

two rods are called tension rods. They pivot upwards from the top rails and

insert  into  the  "Peak  rail" (That part of the top that clamps on to the

windscreen).


These  tension  rods  can  be a real pain. As they are part of the "weather
equipment"  they are very prone to rust. If you have a set that are free of
rust and the adjustments are able to move with no trouble you are home free
but most that I have seen have long ago given up the ability to move. These
have  very  narrow threaded ends on them and are easily broken when you try
to  make  the  tension  adjustment.  Once  broken  they  are  expensive and
difficult to repair so treat them with care.

Tip: rather than adjust them with the screw ends bent the rod body a bit. A
small bend in this area will enable the end of the tension rod to be at the
correct  angle  to the hole in the peak rail. This angle is a more critical
adjustment  then  the length of the rod. Try this slight bend before trying
to  lengthen  or  shorten  the  tension  rod as it may save you a difficult
repair.



Top Bow Webbing


The  webbing  that goes between the top bows is critical for a good fitting
top.  This webbing spaces the folding top bow and the peak rail in relation
to  the  fixed  top bow. It also takes some of the sag out of the center of
the  top. The soft top has two seams across it and these seams must line up
with the top bows for proper fit. Because of this the length of the webbing
is critical to a good fit for your soft top. If you are having a upholstery
shop  install  your new top be sure to have this adjustment made before the
top is installed as the old webbing stretches and is probably deteriorated.
You  can easily do this part yourself by taping the new soft top into place
and installing new webbing to fit the top.

Tip:  Use a black seat belt, with the ends removed, as replacement webbing.
The nylon will not stretch nor will it deteriorate with age and exposure to
the  weather.  It  is  the same width as the original cloth webbing and the
black looks just perfect against a black soft top.



Well good luck and

Godspeed
