1953 Tucker Sno Cat 443 Mt Washington WMTW Channel 8 Restoration

Rear hitch needed to be reworked. Welded in a bushing to return it to 3/4” pin.

I giggled at this comment. Not sure *tucker-tolerance* should be your goal. Great alignment
 
Marty’s wheels headed down to Shrewsbury,MA to spend some time at the axle/diff spa for some rejuvenation.

Burnt Meadow Sno Club Thiokol housings on the relay for life med flight for outpatient surgery shrinking our 2100 down to 8’wide.

Rainy hot humid says Sno Cat to me.

Started cutting out cancer and patching the other side of the frame bottom.

Also added the missing hand crank support bracket that was torn off when I got it. The bottom takes all the abuse.

Using pictures and a caliper to figure out the size in relation to the 1 3/4” tube I think I got it with in OE Tucker Tolerance spec and a close enough repop for the storyline!

Shop got the donor rear ends apart and unfortunately they spent a good amount of time under water:(

Going bring down Marty’s OE rear ends see how those look and hopefully cobble together the best parts for service life.

TBD
 
Got all but two of the exhaust manifold bolts off the 69 442A. The 25” blocks between the 251 and 265 should interchange the exhaust manifolds.

Little more fines needed on the two remaining bolts.

Averaging about 12” per hour from OE tube to finished patch with generous beverage breaks and the occasional safety meeting.

40-50 hour job in an ergonomic setup with half decent tools and experience.

Such a small part of a Tucker project to give perspective on the work involved.

My new set of Hudson Bearing Turbo Socket difficult fastener removal tools showed up today. Great design for rounded rotted fasteners and a must have for the shop!

Was impressive on the first of the bolts. The other one going to need a little more access and finesse but this manifold is in great shape from what I can see. Side engine panel needs to come off and battery tray need to go for better access.

Sourced a nice one for plan b but this 265 was a late enough model they eliminated the exhaust damper which are problematic for this use case. 251 and 265 industrials seem to be same 4 bolt exhaust manifolds so far…..

Another shout out to Turbo Socket! Wouldn’t have got these bolts out otherwise.

My theory has proved correct. 251 and 265 Industrial use the same intake and exhaust manifold but the later 265 eliminated the heat damper.

Intakes are the same as well. 1953 251ci has a 1121704 then a 2. 69 265ci has a 1121704 then a 12. Both look identical.

Exhaust manifold same as well but 1953 251ci 1116679-1 has heat damper. 1969 265ci 1116679-2 does not have a damper.

In conclusion, if you have to source an exhaust manifold for 251/265 25” block, 1116679-2 is the better choice.

Now to separate them…

Very precarious work in this precious exhaust manifold.

The pipe flange was tough. No way the long bolts connecting the intake to exhaust are coming out without breaking the flange.

Consensus is to drill the bolts out of the exhaust manifold. Odd how the 1953 OE came apart but the 1969 is frozen in time.

Mouse was not happy being deported:(
