59 road draft tube

[Robert D.]

just wondering for an early 59 what is the correct draft tube. the TIM&JG manual just states 2 45 degree brazed tubes at the engine connection area(equals 90 degree) and the lower end cut at an angle. during my research i see 2 different ones. the difference seems to be one with a straight and one with a little bend in the part that runs along the top of the engine. the one on my car is the one that is straight. is this correct or do i need the other style to pass judging? if so will the aftermarket ones pass judging?
thanx

I believe 56 to 62 draft tube head original was a round design and later was not. Hope others jump in.

Re: 59 road draft tube

It's believed there are early and late versions of the road draft tube with the change in fabrication taking place around late '59/early '60. Two pictures here depict the difference that deals the construction of the tube's intake head.

The early version (first picture) had a 45-degree angle crimp while the later version used a single piece intake head that was crimped at the tube. The early version of the part is notorious for separating along the 45-degree crimp line with time, age, handling....

So I had it wrong, you say the round head was a later design?

Jack--
My experience has been the opposite. I know that 62 had the 2 45-degree pieces for sure--and believe that later 60 and 61 did also.

Re: 59 road draft tube

our 56, both 57's and our 61, the four having their original crankcase vent tubes,have the two 45 degree type tubes.mike

rich: does the spider moniter your oil pressures? what's with the bolt in the block? regards,mike

Re: 59 road draft tube

...no, he keeps one leg up on the temperature. The prior owner blocked off the oil pipe fitting. Just another thing to deal with when I get to take this wreck apart.

At least I won't have to spring for a new road draft tube. Is that bolt that holds mine on original? No markings on it.

Re: 59 road draft tube

most of the c-1 CCVT's fastners have a small E embossed at the 3 oclock position. I think a small S amy also have been used. when you clean off that bolt, i'd guess its got an alpha character, based on the washer(which looks like the real mccoy) under your hex bolt.mike

Re: 59 road draft tube "jack"

OK so I was correct but the 62 is not a round head??

Re: 59 road draft tube

The 62 is not a round head. Hold-down bolt also can be RBW.

no you weren't correct. your original post stated the 56 to 62 draft tubes were round. the 56 to 62's were not round. mike
