Do I need all of the tools for clutch removal and cleaning or can I get away with just the puller? I keep seeing retainers for everything known to man and want to know what I HAVE to order for it. I am going to be just removing cleaning and replacing the primary spring and possibly the secondary spring.
One more thing. Do I need the puller for the secondary clutch?

Depending what year(chasis) you have. You still might need a puller if you wrap a belt up. If you just want to do maintenance just take out the primary bolt and use a rubber mallet to split the halves. Make sure you align it back up when reassembling(there some marks on the clutch halves and spring cup). You can purchase or make the spring tool. I use a threaded rod a couple of nuts and piece of flat metal(two nuts locked together on bottom and flat piece of metal, put this end in vise, and another flat piece of metal and a nut on the other for removal and installation of spring. I've used the clamps from a dog kennel. This can be used for the secondary also. Be carefull and take your time! -Grover

I believe it's on the ZX and up chassis sled that you can split the primary clutch without removing the entire thing...
Depending on the last time it was off, the secondary should just unbolt and slide off..remember where the shims go...

anyway, check these threads out...
Secondary (http://www.snowmobileworld.com/forum/index.php?showtopic=26119)
Primary (http://www.snowmobileworld.com/forum/index.php?showtopic=25671)

I think it's worth it just to buy the puller for the primary. (I didn't even know they made a puller for the secondary??)

Even if you can service some parts in the primary without removing it from the crankshaft, what happens when you do have to remove the whole thing in 5 years and you've never taken it off so it's fused on there... Better to just take it off once a year IMHO. A good strap wrench for holding the primary during removal/installation is much cheaper than any of the 100+ dollar clutch holders, plus you'll use it for a million other things as well. (I've heard guys at the shop say that strap wrenches can crack the primary, but I think this is urban legend constructed to get you to buy the 100 dollar holder... No one that I personally know has ever cracked a primary with a strap wrench...)

Torque Wrench

As far as spring compressors go, you can make those cheaply.
It would be nice to have a hydraulic press with the right fittings to change the bushings, but I've found that if you take the clutch all apart and bring it to the shop so that the only thing they have to do is the bushings, it's usually not that expensive. If you bring the whole sled in and say 'rebuild the clutches' it will be much more expensive.

A fish scale for reading secondary torsional spring tension is a nice thing to have too.

A good bathroom scale with some kind of fabricated screw-type press (like an apple cider press...) can be used for checking primary (or RER secondary) spring rates.

OK I will be pulling the clutches out at the end of the month and doing some things to them so thanks for the info.
