1977 Tucker 542A Restoration Project

I installed an Eaton electric locker in the front diff. I usually only use the locker when pushing snow, otherwise I end up with one front and one back track spinning. That one locker makes a huge difference in push, and makes the Tucker hard to steer, so use sparingly. The Eaton system is instant lock and unlock, the hardest part is getting the dash safety switch to move! It has some child proof lock on the switch.

Clyde had an older 542? with terra’s out in McCall Idaho one year.

Was with another cat last winter that had them as well.

They don’t float or climb like the pontoon system. Also the contact area and bite on them takes a lot of effort to steer especially at slow speeds.

Perfect for our ice our east but heavy wet and fresh snow adds a lot of stress to the early tucker designs.

Brian, Do you still have pics of the Rangley cat with the track refit?
 
Pretty sure those where MaxTrax which is not comparable to the Terra Tracks.

I’d say the MaxTrax that machine were only useful on ice or hard packed groomers if we are thinking about the same machine.
 
Update - finished up the rear fifth wheel plate repair and track install today. Measured for rear driveline and should have that in end of day tomorrow. We only moved the machine a small bit out of the storage garage, but it definitely did take a lot more throttle effort to move than the pontoons did. We literally moved the old pontoons out from under the cat with one hand while doing the swap today - hardly any resistance on those compared to the new Terra’s. Have to finish hooking up the seat heaters that we never got around to last year (was crunch time for the roadster show) and get our measurements for the roof rack. More pictures to come!

We actually ended up with that exact cat. But they had taken the terra tracks back off at the factory and sold separately. Bolted on some pretty worn out pontoons/axles and got it sold to the gentlemen we ended up buying it from. I think the used Terra’s sold for 41k back in 2020. We tried to snag them but there were others in front of us - that is a steal compared to what they cost now.

They look great on the machine. They should break in and have less resistance overtime. Snow and water on them also will reduce the resistance.

We had a pack of zr 200 snowmobiles when the kids were smaller. The ones with most miles were always fastest once the sprockets idlers and tracks broke in.

Keep us posted!
 
Those weren’t even the molded terra’s like you got now. Those were belted rubber grousers and steel guides like on my 1443. Terra like.

Prob weighed a bunch more and not as smooth as your newer version.
 
Do those chains work as anti- rotation limiters? Steering angle limiters?
Better idea than the welded on square tubes
