Guest JasonDMX2 Posted June 30, 2007 Share Posted June 30, 2007 I have a fs5w71c and the factory service manual does not correctly identify my synchronizer hubs so I have no idea how they go. Any help/pictures of your fs5w71c tranny internals would be appreciated. They both have the right angle cutout on one face, but then on the other face one is chamfered and the other is flat. Now it the manual they show the 3rd and 4th hub as having the cutout and chamfer on the front side and the back is also chamfered. Then the 1st and 2nd hub has a right angle cutout on the front with a chamfer on the rear face. Also, just to make sure they do refer to the "front" of the tranny as the motor side of the tranny, correct? Quote Link to comment Share on other sites More sharing options...
spacecase70 Posted July 2, 2007 Share Posted July 2, 2007 yes that is correct, the motor side is the front, even in a FWD config Quote Link to comment Share on other sites More sharing options...
Guest JasonDMX2 Posted July 3, 2007 Share Posted July 3, 2007 I figured that, but I wanted to be absolutely sure before I put this tranny back together because I am not feeling good about the orientation of the synchronizer hubs. Quote Link to comment Share on other sites More sharing options...
kiwi303 Posted May 23, 2008 Share Posted May 23, 2008 Does anyone have clear pics of the three different gearboxes? How do you tell if they are A, B or C FS5W71 boxes? This site: http://www.az-zbum.com/information.transmission.shtml has pics of a FS5W71C This site: http://www.club-s12.org/forums/index.php?showtopic=9505 has a pic of a C and a B next to each other. But I can't find any pics of an "A" box, can someone help? I know my gearbox is not a C since it doesn't have the webbing over the box the C has in those pics, and has free standing ears and is smooth like the B in the pic, but given my Fairlady has cruise control switches and I haven't met any manuals with cruise control before, I'm not going to automatically assume the box is a B as the chronolgical dates suggest it ought to be if the car was manual when built.

Xnke Posted May 24, 2008 Share Posted May 24, 2008 Hmmm...I wonder what kind of gear ratios the Xterra FS5W71C box has? being as it was made until 2002, it'd be easy to find one in good condition. Presumably, the front casing swap would be the same to fit the L motor. Quote Link to comment Share on other sites More sharing options...
