XX4WE slipper
 

Do I have to use shims or spring? I have both, so far I used spring. And lock clicker or not? Thx for help.

Spring for the clicker. If you wanna lock it shim it to the beginning of the thread (careful to not go over the end or you could snap the layshaft)
I run mine locked with a one way and sometimes locked with a diff.

I have also spring for slipper (lower diameter than on XXX) that's why I'm asking.

And one more question but this time about using LRP Sphere TC. Looks like shell is touching fan. What should I do with it? So far I used Sphere 2007 and hadn't fan on it. I have seen Darren's XX4, but can't see any mods - http://www.oople.com/rc/photos/2008n.../OOP_6883.html

You need a different shell. My hot weather body rubs and my standard (i think it's standard) one fits fine.

my body is hot all year long..you know you want to rub it
get in the gym fat boy

I've got 4 hot weather shells for 2 cars (they came with cars I've bought) and this isn't very good information for me.I've just found postion for my speedo where fan is not fully covered, but body touches it. I've got nats this weekend so I've no chance to get any other shell (I'll see what it will do with hot weather shell after 2 days of racing).

O wait, i think mine rubs on the motor. On the fan it does touch, but barely.

I don't have any problems with motor - I have soldering part now almost in horizontal position. For me shell touches fan all the time.

If it's in the same location as mine then it touches the outside of the fan, not the fins, not a problem as far as im concerned.

Previous position was bad because fan had no air to cool speedo, now there is some air flow and yeah it just touches outside of the fan.

Ive cut out a bit above the speedo. You also need to make sure the rear section of the shell is cutout so hot air can escape.

Do you have somewhere photo of it?
I worry about cutting the shell - dust in fan is no good.

Somewhere at home i think.

Oh ok.

You don't need to cut your shell, just loosen the screwsand push the fan towards the centre of the car and retighten the screws, as it's the screws that rub on the shell.

The easiest way to get more cooling to your motor and speedo on a xx4 is to convert it to an X5!

Oh come on, I'm not done this kind of crow bar advertising for AGES ;) :D

I must admit that I like look of X5 but I can't afford it :cry:

In the position that my speedo is now I can only move fan towards front or rear of car not to centre.

I only said cut the shell above the speedo for more airflow, but i did it when i ran brushed.

I think hole that is for airflow must suck dust in - in this situation directly into fan - that's what I worry about. I'll see temperatures during practice - then I'll decide if "to cut or not to cut".
