You would need to drill a hole through the bearing too though!

About the through hole on the pinion gear, it would seem that they need the hole to setup the part for final machining.

They probably start by boring the cavity for the CVD and the through hole they put the part on an arbor to machine the bearing surfaces and the teeth of the gear. But you are right the screw is just a plug nothing more.

they should make a bevelled clutch bell gear to mesh with the spur perfectly, but other wise that is the best built buggy bare none

Maybe the spur is beveled? It's probably fine either way. The gears will wear in against each other and because of the gearing this car uses it has a high tooth count on the clutch bell so it should wear well.

I was looking at that too this morning, thinking about the gear mesh. I'm guessing when you free spin the clutch and spur for the first time, it may have a little rough sound/feel to it. But, after a couple tanks the mesh will flatten itself out, so its smooth. But thats just a guess...

The idea of a beveled spur gear with an angle so it mate up with the clutch bell would be cool..

Its probably not beveled since if you beveled it it would have smaller teeth on the inside or teeth that were closer together due to the smaller diameter. I dont think it will really be an issue just a smaller contact area.

I think it's simpler for them to accomplish than that. They bevel the diff's ring and pinion gears after all. The Spur can't be put on backwards either (assuming the diff is of fairly conventional design).

Just a heads up on this, just because its a conversion from cSt to W, does not mean that will be equivalent to other brands W oils. IE 40W Losi does not equal 40W AE.

I think you will find that the clutch bell is bevelled . If you look at the diagram on the construction manual you can slightly notice the taper . It would flog out quickly if it did not mesh properly
Who's will come first pitdog , see at the Sunny coast when it arrives

They are both straight, but seriously, this isn't a big deal. I have over 2 gallons on my car, and all is well!

Personally I do not see the need to pull apart the assembly, as I do a complete inspection between race days. Also, the set screw is not needed from what I can tell, but it will help while assembling the parts. What I am confused about is the screw that threads into the pinion. Why is that there? Why not just make the part closed to begin with? Rocco, do you know? I do understand that NOT using the screw will let debris into the dif housing.
The thing that goes into the center of the input gear is actually a plastic 'peg' that fits in there. They did everything to remove weight, its crazy looking over this thing...

The only reason I ask is the old 1-piece mount could be ordered for an OS/Picco engine or a Nova based engine and I do not see that option for the new mount.

Thanks!!!

I really don't know, I'll look over the new parts list and see if I can come up with an answer on Monday, when I get back into the office.

Rocco,

Could you do me a favor, could you measure the length of the 808 outer hinge pin. (#357331) with some calipers. I don't see any measurement (other then 3mm) in the manual.

Thank you!
