Sunroof

[camo]

Hey guys. Ive been really busy lately, especially since summer started, and haven't had any time to work on my car. So, i ended up paying a friend who is a mechanic to fix my sunroof. He got my sunroof working and it doesn't leak anymore, But he said i shouldn't use it because its old and he doesn't think it will last long if i use it. So, what are your thoughts/advice concerning this? Approximately how much would it cost to basically replace the whole sunroof? I definitely want a working sunroof eventually.

By the way, since the last time Ive been on.. I turned 16 still haven't drIven it though

Sunroof adjustment? - Rennlist Discussion Forums

I just google.

you need to second guess what the OP used to describe the problem! Try "sunroof adjust" or "adjustment" as a subject ( show threads) or a response ( show posts). Then try sunroof problems, etc, etc.
OR,
as danglerb just did, know where to go and find them!

whoop many posts while typing. search right here top of 928 main page threads , drop down search this forum put a word in relating to your need, pulls up all threads related red highlighting your word. ------------------------------------


he thinks it old rickity or sluggish ? after making sure of adjust issue , opening and closing while car is fully on not just acc will be more powerful. ---- the motor gear and cable there above back seat lube , gunky of dust/crud struggling motor. mind you this is only a letter slot opening to do this job, one of the evil jobs. headliner has to come out. theres guides plastic can be broken that keep the panel evenly going one can get ahead of another tracking unevenly jams, cables need lube so it will go smooth. the track that all runs in clean grease. from top side of sroof tracks hindges cleaned greased. the adj for the leather sliding panel is over steering wheel adjust so when panel is moving its not scratching along the leather or too high . more to it many tiny screws on top frame lining up the leather liner, all the plastic liners snaps, pillers front and back of drive/pass windows have to come unclip for headliner removal, near rear hatch too. back inside, track may have more plastic pieces like track stoppers or once the liner goes forward smooth it lifts to seal so those track lifters. you can only see in there light and one eye through the sheetmetal frame cutouts and from top side light and can only slide your hands in with no room to move. sure i miss something difficult patient joby. Now motor and track not struggling new- many more useful yrs. with the exception buying it all new and paying someone else doing it all for you , youd be good to go.(exception anything else but no ice cold beers before during or after rewards your not old enough, yes?). few parts cheap/avail and motors dont usually burn up unless laying on the switch forcing motor to go when its jammed and cant move. of course just post ? ...... as your proceeding.

what is the best lubricant for the sunroof?
any special areas to hit, or a good way to get it lubed?

[PC-85-928S]

i know it is important to clean out the water drains as well

[dcrasta]

follow the procedures in the 'adjustment' to adjust the track till its moving smoothly.

I use dry teflon based lube for the roof like Dri-slide dryslide
or this one 'http://www.finishlineusa.com/products/teflon-plus-lube.htm'

Drislide can be found in bike stores. works good in locks also.

[dcrasta]

Oh check the little rubber 'transmission-clutch' under the cover. it connects the motor to the cable transport. That part breaks if the roof has too much drag.

[Mrmerlin]

first spray down the tracks with WD40 then wipe them clean,
do a few times till its spotless,
then lubricate with Drislide or any other long term lubricant

NOTE dont worry about the drain tubes you will probably unplug them then you will have real worries ,
dont use compressed air either, it will blow them off the roof fittings

[Mrmerlin]

found by putting in sunroof adjustment then going to the 928 forum

Ok since your having problems with the roof here is how to fix it..
first you need to tape a piece of the plastic to the the center of the roof panel the clear plastic that you find on the magazines at the DR office is a good thing or a piece of manila folder this will prevent the roof panel from getting scratched while you figure out the adjustments


\ open the roof about 3 to 4 inches try with the switch,
if thats not working then try to twist the black rubber connector at the motor .

Once this is done then look at the front of the roof there are 3 screws that hold the inner liner to the roof,
with a long phillips unscrew these about 2 turns and leave the screws in the roof.

Then pull down on the front of the liner this should disengage the liner from the roof.
Then carefully slide the liner forward,
you will have to open the roof a bit more .

NOTE there are 3 spring fingers at the rear of the roof these hold the liner from bouncing, it is common for the fingers to catch on the inside of the liner and prevent it from being slid forwards,

NOTE also there are 3 felt pads that are on the liner side,
these slide on the inside of the roof so the rear of the liner needs to be pushed up a few MM to avoid ripping the felt pads off when its close to coming out of the opening of the roof.

Once you have the liner out
Get some WD40 and spray the side roof tracks and then wipe them off remove as much of the dirt as possible then close the roof .

NOTE the spring fingers will also spring down when the roof is closed.
You can push the springs on either side to ride on the roof interior you will have to hold the center spring up when you open the roof or it will get bent when the roof opens.

Now with the roof closed there are 4 attaching points to the roof.
The front bar has 2, 8mm bolts at each end with a height screw visible through the bar these screws will need to be blue loctited .

Important these screws dont get tightened up evenly,
they just get run till they are snug,
the loctite will hold them in place,
you also want to count the number of turns of each screw,
so you can install them in the same place.

These front screws will give a tilt to the front bar as well as raise or lower each front corner of the roof, if the 8mm bolts are too tight then it will cause a bind in the front track guides on the bar edges this will cause the roof to bind and possibly get stuck , so you may have to experiment some till you reach a happy medium.

To raise or lower the front corners of the roof loosen the screws on that side then you can turn the flat head screw visible through the bar to raise or lower the roof edge, ( you shouldnt have to adjust these however)

Now to the part that probably causing your problem.

With the roof closed there are 2 transition blocks on the rear of the roof
these are held in with 8mm bolts these screws also need to be locktited into place,
with the roof closed and the roof level with the car roof the bars should be flat or parallel to the track,

With the screws loose you can see how the bars will move to raise and lower the roof, if you press on the inside of the roof panel.
With the roof closed tighten up these transition blocks with the loctite put on the 8mm bolts
and also tighten the phillips screw that holds keyway,
and the 2 flat blade screws on each block .
Make sure the roof panel is flush with the roof,
if its too high then it will scratch the roof better to be a bit low while testing,
try closing the roof tighter while twisting the rubber connection.


Now you want to see if the transmission cables are even,
with the roof switch open the roof and verify that both of the transition blocks move at the same time,
if one side is moving before the other then close the roof and remove the roof transmission,
2, 8mm nuts with a screwdriver pry the cable for the side thats not even till it is,

NOTE you shouldnt have to do this adjustment unless the transition block may have a broken finger where it connects to the transition blocks on the roof panel)
If you find one of the cables is damaged thet you will need to source a new cable 928INTL has them

Once the cables are even replace the transmission slide it back into the rubber connection point .
Test your work by opening and closing the roof,
work slowly so you dont scratch he roof panel,
if the fit is close then you can pull up on the roof panel of the car to give a few more MM of clearance ,
( do this with the roof just open and the rear edge dropped down,)
also be very careful with the center spring this will have to be held up while you open the roof,
it can damage the car roof liner if you forget to hold it up.

Once your roof is level then lubricate the roof rails with some white lith spray grease,
work the roof open and closed a few times see if the roof is smooth,
if not you may have to go back and readjust the front bar so it is also parallel with the roof tracks.

Once all is working open the roof about 5 inches and slide in the liner from the outside of the car fit in the roof, being careful of the felt pads and the spring fingers .
slide the front attach point under the washers on the screws then push the liner up to the roof panel then tighten the screws ,
close the roof and see if you need to adjust liner for a better fit once the roof is closed.

Test your work the roof should open and close smoothly
