Cougar Diff

[martin]

There are a few people on this forum that appear to be having troubles with thier diffs coming undone, one reason for this to happen is that the internal circlip has popped out of its groove and has caused the thrust race to tilt over and it grips the screw and undoes. however when you undo the diff the load is released from the circlip and it pops back into place, giving the illusion that it has not moved. this circlip must be assembled very carefully each cougar kit had an instruction sheet showing how we recommend this is done. you have to ensure that the sharp side of the circlip is against the washer carrier, slightly open the circlip before you assemble it and place one corner of it in the groove of the washer carrier and push the other side in while squeezning it as little as possible. when the circlip is in the groove it must be tight and difficult to move, if it rotates freely or has some side to side movement remove the clip and try again.
