67 Needs New Rear Sprockets

I noticed yesterday that the rear sprokets on my 67 Oly are toast, actually look like mush.    I think this happened because the rear set of bogies was seized in a bad position and let the track ride high and outside the track windows.  I had the track spinning yesterday and there was little chunks of rubber and rubber dust all over. 
So I'll be replacing the rear sprockets.  It may be personal preference, but what are you guys replacing the rears with,  The rubber or the hard plastic? And Where's the best place to get them?  Gonna replace the all the rear springs too while I'm in there.
Thanks, Mark

DOO640ER I USE ONLY THE HARD PLASTIC/FRONT DRIVERS ON ALL MY SLEDS. I HAVE HAD PROBLEMS WITH THE ORGINAL RUBBER ONES ON TRACKS THAT DOO NOT GET USED ALOT OR A SLED THAT HAS BEEN SITING FOR AWHILE. THEY WILL "WALK" OUT OF THE HOLES IN THE TRACK.

SOURCE IS SMARTREC 800 871 8966 GET THE KIMPLEX SPROCKETS ONLY SEE PIC OF SPI AFTER 20 MINUTES OF USAGE    PART NUMBER KX 4102 MAKE SURE YA ASK FOR KIMPLEX!!!

Thanks YETI,  doo ya have a part number for the seals?  Also what bearings did the 67 use? The typical 6205?

I see Kimpex makes the hard plastic 04-102 and rubber 04-103 sprockets.  Some say to use the rubber on the rear because riding on a hard surface can break the plastic sprocket.  I have the hard plastic ones on my Nordic and they doo appear chipped.

Doo you know if Smart Rec sells the bogie and link plate springs?  I didn't see them on their website.

I've had great luck with the oem nos rubber sprockets in all cases and they haven't shredded. Maybe they had a better durometer rubber compound. The 570-0101 or 570-0118's on the back and the oem nylons 572010200 on the front. However even ski-doo super'd the rear rubber ones with their nylon ones on the last made elans. Theirs are not quite as hard as the kimpex ones, but have never had them get whittled down like the spi ones shown. It's too bad the spi ones' closest mimick the oem ones. Last i knew the oem ones were still available from Bombi at like 20.00ea thereabouts. I think its a pref thing, and if you are riding on snow and general ice as opposed to rocks and that the hard ones ought to be fine. There are a lot in service. I heard the price spiked huge this year though so hold on.

Thanks Hermit for the part numbers.  I think I'll go with the rubber ones for the rear.  I doo tend to doo a lot of riding on hard pack roads around here, plus if I change these now, I'll never have to doo it again regardless.  I'll never put that many miles on it.

For what it's worth I always use the Kimpex rubber sprockets on the rear and have never had any problems with the tracks jumping on them.  But then again I don't get many miles on my sleds around here.

Thanks Tony, I like all the advice and opinions I can get.  Word of mouth and real-life experiences of others really help out when making educated decisions.

Just ordered a set of Kimpex sprockets from Smart Power Sports for about $9 something a piece (on backorder). The guy I spoke with said that the other of the two companys they get parts through was listing them for around $25 a piece now. Also thanks for the info and part numbers, it really helped in tracking the sprockets down.

Finally got a little bit of time to work on the 67 today. Assembly of the sprockets and axles on the kitchen island countertop.  23 degrees F outside  and pretty cold in the garage.  No heat to speak of.  Wife loves when I doo things like this, but as long as I have a smile on my face then she does too




Got the stainless steel screws and locking nuts from McMaster Carr. 330-995-5500.  I have posted the info here in hopes it could help someone else who comes along searching.

10-32 Thread X 5/8" Screws:  Part # 91783A830 Qty 2 packs @ 100 per box @ $6.05 per box

Nylon Lock nuts part # 90715A115 Qty 3 packs @ 50 per box @ $10.41 per box.

Not cheap  but will last my and the sled's lifetime.  I used the John Deere Medium Gloss Black paint, which you can see now needs to be touched up.  I think I'll paint the screws also to make it look more original.  Haven't decided.

The front sprockets are the Kimpex hard plastic version.  The rears are hard plastic also and were produced by Marshall.  I like that they are black and look more like the original soft rubber ones.  Now on to the bogie assemblies 
18 screws down and 72 to go

Only one reason I used pan head screws.  That's what was original to the sled.  Unfortunately I apparently have a little OCD and want it to look as original as possible.  :-  This is likely good news for some of the site sponsors and I'm putting together a shopping list.  Are there bulk discounts ?

Thanks for the great comments guys!
