1998 Summit X 670 Track Size/Drivers

[meierjn]

Good day everyone... I have a 1998 Summit X 670 with the stock 136" 1.75" track still on it. The existing track has a couple of torn lugs but should get another season out of it. I am looking to replacing the track in the future with either the same track with 2" paddles or doing an extension to a 144" with 2" paddles. I have the stock 9 tooth drivers still on the sled. Will the existing setup accomidate the larger 2" track or will I have to go to a smaller drivers with less teeth? Thanks in advance for your help.

Either drop and roll or 8 tooth drivers to fit a 2" track. With out a doubt extend the track to a 144 or longer.

A bunch of us worked on a 670 Summit last Wednesday night, tried to place a 2" - 136 on it, too large!, we ended up cutting down the track a little bit...

It took us a little while to get rid of about 1/8 , look at the pic to see the pieces of track on the floor!

Just put a 144X2 inch on my sons 1998 583 put a set of 8 tooth drivers on it and was good to go. I picked up the drivers from my dealer The 1998 670 non X came with 8 tooth drivers. I put the stock set up on didnt go with extroverts. Part numbers for the stock set up are 415067400 for the 1/2sprockets and 414931800 for the full sprockets. I also ordered the track and 136-144 rail extentions for tracks Canada.

get ahold of summitx on this site, he knows a thing or two about the ol summit x's

Get some 8 tooth drivers and go to a 151" track. Go with extroverts and you will be able to run the track a lot looser which will hep the friction reduction big time!

And as Modman says...that's exactly what you want to do...you'll lver the change.

Yes do what everyone is saying, if you go with a 144X2 with 8 tooth exto's you won't have to gear down as the drivers will make up the difference, I just up from the 144 to a 151x16x2 and geared down in the chaincase also. The 144 was much better than the 136 and the 151 x 16 is like night and day. A little more work getting the 16" wide track in but well worth the trouble. Keep us posted.

Thanks for all of the help! Sounds great. I think I will end up with the 144" track with the extroverts. Who around Edmonton sells good rail extensions, tunnel extensions, and good extroverts?

I bought rail extensions from slp for my 98 summit. I think someone mentioned tracks canada or tracks usa.

Cheers

Where did you get the SLP stuff from?

Where did you get the SLP stuff from?

I got my rail extensions (SLP) from Cycle Works - West.

 

[hanrock]

hey i have the same setup on my 98 x 151 8tooth the extensions are from tracks canada these alowed me to run the hyfax all the way back made a huge difference in the sled

 

[meierjn]

So, If I go with 8 tooth extroverts do I have to move the skid back any or jut leave it where it is and all will be fine? Thanks for all of the help everyone!

 

[hanrock]

you only need to move the skid to make up for the longer track if you dont use the extensions

 

[meierjn]

Thats good. I had read somwhere thet the extroverts would rub on the end caps on the rails.

 

[99summitx]

I think that's mainly a polaris problem.
