Subject: 9000 Door Latches - nice action restored


This is a multi-part message in MIME format. ------=_NextPart_000_018D_01C40E1D.DBA3C4C0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable I would just like to share my experience of renovating the door latches = on my '92 9000 CS. This post comes with a recommendation to other owners = to give it a try. Big improvements for very little work. I dare say that = 900's latches are similar, maybe even identical, although the external = appearance is different. Introduction :=20 For some time the rear near-side door handle was stiff to operate. My = poor old Mum (now 80 years) found it all but impossible to open and even = my Dad (also 80 years) was beginning to find it a bit too much, though = for me (a strapping 48 years) it was no more than an annoyance.=20 Earlier Attempts at Lubrication :=20 On several occasions over about 2 years I had unsuccessfully attempted = to lubricate away the stiffness in the offending door handle by applying = grease and oil to the normally visible parts of the latch mechanism. = This had no effect so I put up with the problem.=20 Stimulus for Action :=20 On a recent trip to Woking to see "HMP Pinafore" (Carl Rosa, with ex Dr = Who - Colin Baker - as Sir Joseph Porter) my neighbour Bill (ex biology = teacher, circa 65 years, 6'2", 19 stones, 266 pounds) found he could not = open the door from the internal release lever. I was prepared to believe = that Bill's great weight was at least partly to blame until I managed to = reproduce the symptom the following day.=20 Immediate Action :=20 I removed the door trim and shortened the release link rod by about 3mm = by judiciously bending into it an slight extra dog-leg. While I had the = door in bits I sprayed everything in sight with GT85 (no WD40 to hand). = I reassembled the door trim with much gnashing of teeth due to its = recalcitrant nature.=20 The door release problem was thus fixed however I was surprised to find = that the door handle stiffness persisted. =20 Aha :=20 Whilst the trim was removed the only parts not clearly visible had been = the mechanical interfaces of handle-to-latch and release link = rod-to-latch, which are pocketed in the door structure. With the trim = now reassembled, it seemed sensible to try removing the "external door = lock assembly" (Haynes Manual, p 11.8, fig 13.23). This item (about the = size and shape of a leather pocket-saver for coins) comes free after the = removal of three chunky crosshead screws, all of which showed slight = signs of corrosion. Now visible on the reverse side were two spigots, = the upper one being the release arm and the lower being the transmitter = of latch position to an electrical switch (for SID and alarm functions). = The release lever showed signs of corrosion, so was tidied up with fine = emery paper, moving parts greased and reattached with plenty of grease = on the screw threads for good measure.=20 WARNING: I found that the external door lock assembly needed to be = reattached (to the door) with its latch mechanism in the LOCKED = position, otherwise the lower spigot failed to engage correctly and = actually bent on first shutting of the door (easily straightened with = pliers but I wouldn't want to do it too many times!). Remember also, = after reassembling locked, to release the latch by using the door handle = before closing the door for the first time!! Again, this avoids damage. = These aspects are not adequately covered in the Haynes Manual. PROBLEM CURED - all traces of stiffness had now vanished from the door = handle.=20 Epilogue : My car's worst door release action was now the best so the next day I = went round the other three doors and greased their external door lock = assemblies in the same way. As this did not involve removal of any trim, = the job took about 30 minutes to complete. Tools required were ratchet = lever with crosshead screwdriver bit, plus a few dabs of Castrol CL = grease.=20 Recommendation:=20 For that wonderful new car feel to you old tired door latches, dismantle = and grease them. Do not rely on external lubrication alone to keep them = in tip top condition. Allow one hour for all four doors, including = learning time on the first door.=20 ------=_NextPart_000_018D_01C40E1D.DBA3C4C0 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META http-equiv=3DContent-Type content=3D"text/html; = charset=3Diso-8859-1"> <META content=3D"MSHTML 6.00.2800.1400" name=3DGENERATOR> <STYLE></STYLE> </HEAD> <BODY bgColor=3D#ffffff background=3D""> <DIV><FONT face=3DArial size=3D2>I would just like to share my = experience of=20 renovating the door latches on my '92 9000 CS.
