Is there a way to manually raise or lower the cabriolet soft top?
I started to lower my top and heard a loud "POP" from the left side gearbox area. The right side continues to function normally (no, I don't move it very far), but the left side appears frozen. The small "disk" visible where the motor shaft enters the gearbox does not move on the left side. I suspect a broken shaft, or stripped gears somewhere between motor and gearbox. Anyone have an experience/solution to share?
well, if you think about it, it doesn't tell you anything at all about restoring it to power mode. they probably figured people would freak out if they knew it was a one way trip.
the cab top manual does tell you though. it's buried in there, but it's there. what it doesn't tell you is how to synch the motors if you get them out of synch. that was a real bear.
I finally attacked my cab top, starting with the left cab main gearbox. If you have never viewed the inside, it is fairly simple- the cable from the motor leads to a worm gear, which drives a small planetary gear system which reduces rpm and increases torque. The planetary gears engage a semi-circular gear, the center of which is the rotating portion of the gearbox to which the activating arm is attached (the hole in the center of the gearbox where the large "one-use" bolt engages. I would post pictures but didn't take any due to the large amounts of grease on my hands.
Problem 1) The semi-circular gear had turned beyond it's arc, disengaging from the planetary gear. This prevented the left side gearbox from moving when the up/down switch was activated by the driver. This is probably a result of the gearboxes not being properly sync'd by the previous owner/mechanic. (This was mentioned by "Flash" in an earlier post.)
Problem 2) As a result of the asymmetrical torque applied when the left gearbox disengaged, the right side "main folding top bow" (P/N 941-561-202-11) broke. (Also mentioned by "Flash")
So, once I acquire an affordable main bow, I will be able to continue my repairs and get the top fully serviceable.
Anyone have P/N 941-561-202-11 available at an affordable price?
UPDATE: This is a belated posting. I completed the repairs back in Nov-Dec 2015.
I carefully removed the right main bow without removing the entire top itself. Took some time but, but no issues. I took the bow to a local (reputable) welder, who inquired about the nature of the part (to ensure the weld did not interfere with it's function) and who welded it for $30.00 (much better than $1250 new). I took the welded bow home, ground smooth the side to which the fabric is adhered, then carefully reinstalled it using 3M heavy duty spray adhesive. I have been (and always will be) using it in manual mode, with no further issues. The fit is fine, as I was careful not to disturb the shims at the base of the bow's mounting bracket. Pictures attached.
yes, there is the manual operation to crank down the top. most common problem is just a fuse for electric use of putting top up and down. I DO have a suggestion for ALL cabriolet owners- either you or have your mechanic disable the entire mechanical top. and just put it up and down with your own hands. If the support bars and motor screw up-ur lookin upwards of $7000
I disconnected the motor a year ago after hearing about all the "nightmares" people had with the out of sync syndrome. Keep in mind 90% of the operation is manual anyway.
