1973 Tucker Sno Cat 1443 New to Me

Oil pan installed with new upgraded hardware. Little leaning curve to get everything lined up. Had to call in the wife for support!

Will add oil and fire up tomorrow see how I did…

Primed the oil pump fired up slant and brought to operating temp. No leaks yet!

Added some hose chaff protection in a few areas that wouldn’t hurt then pulled the sliders and sprockets off the carrier.

Will reverse the sprockets on assembly to spread wear.

Paint and bearings all that’s left.

Built a track wall today as well.
 
New bearings races seal for 8 of the front idlers. Did three last year but can’t remember which one on the passenger side.

Missing a number of seal retainer washers I think are still available.

This cat has one new style idler shaft and a number of oring spacers which are prob because they bought new wheels. New style eliminates the spacers, retainer washers, and one seal. More akin to a snowmobile trailer wheel hub.

I eliminated those thin washers that sit next to the seal. The don’t make sense to me. The are too far away from the seal to make any difference in retaining the seal, and if those washers touch the seal the washer either spins or takes out the seal.
 
I'm hanging on to my stuff for now, including the original front slide tensioners in case something goes wrong with the Tip Toe's.

It is the first time I've seen the use of thin stationary/floater washers to back stop a loose grease seal. On the transfer case I noticed a flat face screw is used to lock the seal in place. That style of seal retention I can understand. Not so much for the washer. Definitely don't want to over grease the idler wheels and pop off a seal though.

Cleaned up the carriers in prep for paint.

These carriers experienced some trauma in life by the idler before the icebreaker. Odd repair on both sides and primer on the slider mounts. The original table was welded. The force seems like both carrier noses went down in a crevasse pivoted up and hit the stops with extreme force. Few signs of grousers knicking the aluminum body.

The front passenger side carrier is newer or different that the other three. Beefed up adjuster screw receiver support and has c clip groove for additional carrier retention.

Paint in progress.

I really like the idea of a trailer style axle stub shaft to hold the wheel seals and bearings. I couldn’t tell whether there is a bearing cap on the outside to complete the setup?
A problem I noticed immediately is that the through bolt used to retain the “trailer axle” in its tube is going to be loose and wear the welded tube. So the axle needs to be threaded to snug up the axle or tack welded to retain the axle.
I found one of the axles was loose in my Tucker track frame. My temporary fix was to beat the tube a bit on each end and then drive the axle through so the slack is gone for now.
The tensioners on both the rear frames on my Tucker needed to be replaced as well. Must be lots of stress back there.

Bell housing cover on. The bolt behind the starter is almost on the verge of child labor.

Carriers getting ready for paint. Trunion frame ready to go in. Idlers lined up for new bearings and seals.

Should be ready to rock by December 1.

Making room for the Haverhill Santa Parade float coming in for Sunday. It’s time Kitten takes a lap around town!
