polaris XCR 700

[Jeremiah]

Picked up one of these, just rebuilt with a performance rebuild kit, doesn't come with clutch but it was $250. Now I need to know what kind of clutch/torque converter to put on it. Any Ideas?

 

[Bluethunder3320]

i would get a clutch setup off the correct engine.

 

[Jeremiah]

Would but they dont manufacture them anymore.

 

[j.concepcion54321]

what size engine is on it??

 

[Bluethunder3320]

what does the shaft look like? keyed?

 

[Jeremiah]

yes its keyed with threaded bore. I think I'm going to use a ford f150 torque converter instead of finding a new clutch. If the engine idles at 1500 rpm would a 2600 rpm stall on the torque converter work?

 

[j.concepcion54321]

is it a go kart that you bought?? or a snowmobile?? cause i looked up that name and it came up as a snowmobile...

 

[Jeremiah]

snowmobile motor

 

[j.concepcion54321]

ok that makes sense..... dont they just have regular keyed shafts?? i was looking at a polaris 340 a while ago and it just had a reguar keyed 3/4 shaft. if so then find out what size shaft you have and then just get a normal tc like a comet 40 series. i think that would work, and if not look around on ebay im sure another polaris clutch will fit it....

 

[Jeremiah]

that will handle 100+ hp?

 

[B man]

NO! you will need totalk to a polaris dealer.

 

[Bluethunder3320]

im sure they have the same clutch on other engines..

 

[redsox985]

Maybe give CVTech a call. They seem to make some heavy duty stuff.

It WILL have a tapered shaft, so you WILL need to find a sled clutch. If you want to save yourself the time and possibly a little bit of money, You could probably just fit another clutch that is set up for another motor and fine-tune it with new weights/springs.

 

[bighead]

You need the original engines clutch. And the Original driven clutch. Or ones to mix and match.

I think a lot of sled engines are 30mm tapered shaft. Ebay 30mm sled/snowmobile clutch.

Here is one for About $34 shipped. Conform you have a 30mm tapered shaft though. Then look for a driven clutch that take the same sime top belt width that the clutch you get.

Also the Honda FL250 driven is 30mm but uses a much smaller belt than the sleds use.

Does this engine require a CDI to create ignition? Or can I run the coil primaries to the correct stator outputs?

 

[bighead]

Yes I am pretty sure you need the complete CDI setup. The voltage reg. as well.

 

[Jeremiah]

That's no big deal, found some for 50 bucks on ebay. Things are coming together with my project. all that's left is the CDI and a clutch. Going to use a transaxle for forward and reverse, if it breaks it breaks ill put something better in but for now it will do. Found a local ATV/Snowmobile junkyard to turns out the owner is a friend of the husband who married one of my friends so I got the hookup there. I'll make a thread when I start fab'ing up my frame and drive line.

One more question:
Will this CDI work? http://cgi.ebay.com/Polaris-xcr-800...wmobile_Parts_Accessories&hash=item5199855767

and I dont see 3 connections from the box for the 3 coil positives. How do I connect this to the coils to produce ignition?

 

[bighead]

I would not chance it and get the right cdi for your sled.

 

[Jeremiah]

might be able to get one through a dealer otherwise used they are very rare I've found
