D300 Shift Rail Detent Springs

I noticed that my detent springs were actually different sizes. Not in length or width, but in the diameter of the steel itself. Obviously resulting in a stiffer spring.

Is there a reason one is stiffer? I didn't notice which rail, front or rear it came from. Do you think it will matter which one it goes back in?

Better yet does anyone have a part # or source for a stiffer than stock spring. My Tera 4:1 install manual recommends a stiffer spring or a shim when going to twin sticks.

Re: D300 Shift Rail Detent Springs

The part #s are the same for both balls and springs. Maybe the previous owner took it apart, lost a spring and replaced it with something close. BTW, how did your battle with the output shaft end play come out?

Re: D300 Shift Rail Detent Springs

I've noticed on the three I've worked on that one spring is usually longer than the other and not necessarily because one bore is deeper than the other.
Can't say which side though ... they usually go ZING when the rods come out ...

Re: D300 Shift Rail Detent Springs

Both of my springs are the same length. I guess I will put some new ones in just to be safe.

There was some evidence that this case had been opened before. They probably did have to replace a spring.

Brad, I got the end play set at .001 . I really had to pry to get it to register on the dial indicator. But I made sure that the shaft moved and nothing else. Should be good. The front output went easily. I guessed using new shims and hit .002 first try! [img]/wwwthreads_images/icons/cool.gif[/img]


Now I have to get the intermediate shaft installed and do the twin sticks. I am trying to decide if I should just buy the Currie now or build my own.

Re: D300 Shift Rail Detent Springs

BigHG, this brings up an interesting point. You say the manual recommends stiffer springs when going with the twin stick shifter. When I built my twin sticks I noticed that on steep downhill decents the t-case sometimes pops out of gear. I thought the shifters were hitting the cover I made and were popping out of gear. I rebent the sticks but have not had a chance to try it out yet. But now that you mention the stiffer springs, I'm thinking that may be the real problem. Will the stiffer springs help hold it in gear better? If you get a line on the proper spring, let us know. Thanks.

Re: D300 Shift Rail Detent Springs

Tera suggests using a stiffer spring or using a shim .050-.070" thick to stiffen your existing springs. I found some washers that would be perfect. That is probably the easiest way to fix it.

Good Luck, that doesn't sound like any fun!

Got a pic of your twin sticks? Specifically, how they attach to the shift rails.
