Sector gear inside the transmission

[strawfordt]

Hi all,

I searched the forum but did not find an answer to my question.

My top appears to have over travelled and the sector gear inside the transmission travelled past the worm gear that is attached to the cable. No big deal really as I have the unit apart and have found my problem. I want to put it back together but.. How do you set the positional relationship between the lever arm and the sector gear so that the rotation does not bring the sector gear out of the worm gear again.

The pic on the right shows the position that the sector gear was in when I disassembled the transmission and the picture on the left shows my ignorant attempt to reset the sector gear.

Has anyone had to re-assemble this before and if so how do you know what position to set the sector gear?

Any help is appreciated.

Thanks

Tom

Okay... I realise that my question was stupid!!!

After looking more closely, I noticed the there are two lugs on the lever arm that fit into the transmission. So I think that this problem is solved.

HOWEVER, my top was previously timed perfectly and never did it make any noise when opening or closing. Now it is struggling and makes a few scary noises. Sometimes the clam shell stays open about 1". As the top is moving the sides are not moving smoothly and one side sometimes jumps to a little to "catch up" to the other side.

I reset the lever arm positions using a small level and I reset the adjustable arms that have the plastic ball sockets that always break before I closed the top.

I have a 98 Canadian Boxster. It has the new flexible shafts cables.

Still looking to hear from the experts.

Thanks everyone, especially those that are trying to help.

Tom:

Take a look at the "marking notches" on the outside cover of the transmissions. The V-Lever arms should be in between the notches. Of course, you already know that there are two cut-outs on the part of the half-moon gear into which the 19MM bolt gets screwed into. So, unless you are 180 degrees off, the V-Lever can only be bolted on one way.

Take a look at post # 12 in this link for a photo of the marking notches with the V-Levers drawn in red: http://www.renntech.org/forums/index.php?s...amp;#entry75978. Note that you will have to remove the V-Levers again so that you can press the foam liner back in place (because you can't see the marking notches with the foam liner in the way. But, once you put the foam liner back in place, line up the V-Levers with the cut-outs and they will be in the same exact position as you had them with the foam liner off (i.e., in between the marking notches).

When I did mine, with the transmissions off and opened up, I just set the half-moon gear at the beginning of the 50 teeth and then, by spinning each cable with a drill, I moved each of the V-Levers so that each one in turn lined up between the marking notches.

Let me know how you make out or if you have any further roadblocks.

Regards, Maurice.

Maurice,

Thanks, I did get the transmission back together but the top did not move smoothly. I was trying to adjust the timing but I noticed that the pass side was not moving again. I am supposing that the sector gear came out of the worm gear again. I will disassemble the unit again this weekend and if I have troubles I'll post again.

Thanks.

When you take the transmissions apart again, before you put the black plastic covers back onto the backside of the transmissions, if you hold the V-lever against the opposite side and spin the transmission so that the V-Lever is located in between the "marking notches" (as in the photo in the link above), you will find that the half-moon gear is engaged and not far from their starting point.

Also, make sure that you snug up the four screws (plus the nut on the fifth one in the middle) that hold the smaller plastic cover on top of the worm gear. Apparently the black plastic cover compresses over time and the screws, even though they have not backed out, end up loose. That sometimes causes the worm gear to skip and will eventually throw the timing off.

Looking forward to see how you make out.

Regards, Maurice.
