Attak - Transfer Rod clunk?

[vipermike2002]

I hear a clunking coming from my rear suspension while trail riding slow over larger bumps. When the ice melted I investigated a bit a found the transfer rod has some play in it. (See YouTube Video)
Other posts say this is normal but Im thinking I have a worn bushing or spacer. Whats the fix for this?

Looks like your bearings, index 59 on Track Suspension 2 illustration found on most Yamaha dealer sites, are shot. Here's a link to Port Yamaha, a site sponsor: https://shop.portyamaha.com/fiche_s...=Snowmobiles&make=Yamaha&year=2007&fveh=33549

I saw that also when I looked at the fiche. Actually emailed Kevin asking about #59. But then I started to find posts on here and people are saying it is normal.

Clunking of the transfer rod linearly (Along its axis) is normal. I mean the rod inside. You need new bearings in the eyes.

Agree with ramsomair your needle bearing is probably 100% gone with that much movement,I had to change these on mine(be very careful installing new as the oem bearings are a plastic cage&pretty easy to damage

I have removed my transfer rod every couple years and cleaned the needles with Brake Kleen then repack with grease. 30,000km and still good!

I take it I need a press to remove and install new bearings?

I did it without a press

Deep socket and a vice

You can do it with an arbor press or vise(may need to use a shallow socket depending on size of vice)also there are 2 small shaft seals on either side of bearing that should be replaced.can press in or use a bushing/seal driver set

Am I risking anything driving the sled with this issue?

Wearing out the rod mount due to the slop so the new bearings and seals won't fit properly...just a guess on my part.

If the rod comes apart it could start a #*$&@ storm of broken pieces potentially destroying your track.......worst case scenario.

With track lifted off the ground transfer rod does not move much at all.

no they don’t have a lot of travel anyway but they play a very important role of transfer in the mono skid
