Did I say "tick it off the jobs-to-do list?" Why do I bother....
I've got a complete motor plate assembly (944.624.055.01) from a 944 and had a go at fitting it. This has yielded a few more problems (yes, I'm beginning to realise now that the solution of one problem creates a couple more).
First step, keep it simple to start with. I attached the new motor assembly to the plate on the drive cable "" you know, the little plate attached to the end of the metal cable sleeve, with the 2 holes and the cutout where the drive pinion engages on the cable. Excellent, that was easy, I can at least bolt the unit in. Wrong!!! The 3 rubber-bushed studs that should mate up are about an inch out, with the motor plate being about 1 inch further forward than the corresponding mounting bolts/holes on the bodywork. So, dismantle and pull around on the cable to see if I can "˜release' a bit more. No go, and I had visions of the metal sleeve, along with most of the interior trim and headlining, coming out so I stopped.
Took it apart and put a straight edge from the front-upper mounting hole to the single lower hole. The pinion cutout on the cable sleeve is about 2" forward of this line. Similar check on the plate itself shows the drive pinion about 1" ahead of this imaginary line. Yep, that's consistent with it not lining up when I bolt the 2 bits together. So, anyone got a 924S who could check the part number of their motor assembly? I'm sure they should be the same for a 944 and 924 of 1988 vintage, but maybe not"¦.
The remaining problems are probably easier to look at and describe on the car, but in summary I'm baffled by the Clarkes Garage reference to the 3 microswitches, when they proceed to only mention switch I and II from there on. With the plate lying loose in the boot, and the motor lead connected I can work out which switches should be closed at which time. I move the cam by hand to simulate the correct microswitch triggers but nothing happens when I try the switch in the car (but I haven't checked that yet to see if it's connected to anything"¦) Oh, and how is the cable supposed to locate in the plastic cam? I can't believe it fits together as roughly as what I've got "" I'm sure they must have designed something mechanically better. Again, perhaps something's missing.
BTW "" I can manually raise and lower the roof with the assembly together, but not sure how to remove the roof completely. What should happen when you release the front levers? When I do, the 2 lifting arms are still firmly up against the back of the roof hence I can't see how I'm supposed to slide it back. Because I've never seen one in action I don't know if it's correct or not.
Basically I'm looking to try and eliminate a few problems so that I know what's left to solve, but not knowing what it should look (and behave) like, I'm a bit puzzled.
Congratulations if you've read this far, thanks for your patience. Any thoughts?
I've posted to R23 to elicit any local owners, but I thought some of the 924 experts may be able to help. I can send photos if you're interested.
Thanks"¦"¦"¦"¦"¦"¦ Phil
