2007 RXT supercharger rebuild question.

[xintersecty]

FINALLY did that wet test this weekend.

These things are seriously QUICK! I also noticed they don't ride good until you are going around 35mph. Below that it would wander in small waves or ride just a little side ways on smooth water. Once over that 35 mark they smoothed out and ran straight as an arrow. Does that sound right? Or do I have some other issue?

I have a 2007 RXT and a Spark. After riding the Spark the RXT is on track from 0 up+! The Spark slides and the RXT is on rails. In fact it pulls so hard, I am grunting to stay on!

Also makes a difference depending on where you have he VTS set. High bow can willow a bit but will go faster on the top end. My RXT-X is on plane so fast I keep the bow up always with one exception. If going 20 to 30 MPH and playing in trails or doing curve and jumps kind of thing.

Two of my spring washers,where the small section meets,didn't look like they were lubed.Coulnt see that until taken apart.Just a visual inspection ant worth much.

This might be ceramic,has yellow greenish on outer edge.

No VTS on this unit.

Thanks for the reply!

Thanks for these photos. I will pull them back out and check again. Also for the spring washer wear.

Update...

I received one of two SC kits and a tool kit last week. Pulled the SC Saturday AM, rebuilt it, and reinstalled and all ran great. It did have the ceramic washers just like the photo In post above. For those reading this for the first time. The SC rebuilt is relatively easy If you have any mechanical ability. Most tedious part is installing the 40 needle bearing. I did it a little different than most of the videos etc I have seen. Someone else on here mentioned they grease the shaft, place gear on shaft and then load the needle bearings in. This is what I did also. If the bearing began to get a little crooked, I simply would push the gear into them and turn it just a little and the needles would straighten right up.

Thanks to all for advice and sharing!

Thanks, I did watch that video at least twice. It is very well done and I like all the 3ft deep videos (Thanks 3ft crew!) For me... it just made sense to do it the other way, and it worked out really good.

One other thing that gave me a bit of trouble was removing the large piece that covers the inside bearing and holds the oil seal. A long handle breaker bar or ratchet is needed for this.

I watched the video listed above and I saw a new tool I have never seen before. What is this tool?


And if you don't have it can you just use a torque wrench set to 90 foot pounds?

 

[ski-d00]

it's just a dial torque wrench, a little old school but fine. I prefer my snap-on techangle.

Not sure if a regular torque wrench would work right, but I don't see why not. \

I did however rewatch the 3ft deep video and the spec is 80-120 INCH pounds, not foot pounds.

 

[xintersecty]

oh I have made the inch to foot pounds mistake before and super stretched a couple of bolts. Yeap not making that again. Thanks catching that!

Using a dial you'll see your max,just like a digital torque wrench at the slip point. Using the gear holding tool you'll get a better (easier) range reading.It only needs to be with in spec from what I've heard.

It's a dial torque wrench with a max reading arm you hold the gear then turn the nut until the gear slips the max reading arm will stay at the maximum torque achieved before slip. You can check slip with a conventional torque wrench it just takes longer as you have keep slowly increasing the torque setting on the wrench until the gear slips before the wrench clicks.
