HI,
I just changed my gears from 4.10 to 3.55. The truck is an 87 with a C-6, stock tires. Can anyone tell me what speedo gear I need to get the speedometer close.

 

Try this

Thanks Festus, but I really didn't want to pull the tail housing apart and count drive teeth. I was hoping that someone would know which speedometer gear, how many teeth, I need since 4.10 and 3.55 rear gears were the only options at the time.

 

What size are the tires, what trans do you have?

If you have a speedo cable, there are two gears, Drive & Driven.

 

It's a C-6 trans, stock tires. Stock tires are LT235/85R16. Ford Dealer here
THINKS the correct driven gear for a C-6 with 3.55 rear gears is part #DOAZ 17271 B. That is a 16 tooth driven gear. He has ordered it for me. I just pulled the original driven gear it has 19 teeth. Any help will be appreciated.

 

That's probably right, I would say the C6 has a 7 tooth drive gear.

If the C6 has a 7 tooth drive gear, with 3.55's you would use a 16 tooth driven gear...

I would of suspected a 18 tooth driven pulled. The 19 is a bit puzzling, could have been done for smaller tires previously.

The DOAZ17271B 16T driven gear is not listed for any C6/355 combo, regardless of what the tire sizes are.

No 16T gear is listed for your application.

The 19T driven gear you removed, which way are the teeth slanted?

This way: \\\\ = DOAZ171271B or this way: //// = C7VY17271A = 19T.

C7SZ17271C 17T driven gear is what I came up with for your application. Its teeth are slanted this way: ////

C7SZ17271C: MSRP: $2.00 // FTEpartsguy.com price: $1.44.

btw: The 7T drive gear mentioned by Festus is correct, but it's made as part of the output shaft, so it cannot be bought by itself.

Speaking of Festus Hagen (Ken Curtis). Ever wonder why he acted in so many John Ford films?

He was married to John Ford's daughter. Ford got him the role in Gunsmoke. He also got James Arness his role in Gunsmoke.

Ford was a good friend of Andrew McLaglen who produced, wrote and directed many of the Gunsmoke TV shows.

McLaglen's dad Victor was part of John Ford's "stock company" as was John Wayne, and for a time, Arness.

 

John Wayne had something to do with James Arness getting the part too. They were both football players too, not sure if both were at USC but I THINK they were teamates. Arness was in at least one JW movie before he did Gunsmoke.
Obviously John Ford and John Wayne had kind of a Father-Son thing going on.
I believe John Wayne even did the intro of Gunsmoke AND James Arness in/for the very first episode, back when it was black and white (like 15 years before I was born).
I've never seen a black and white Gunsmoke episode but I've seen every color one they made, on TV Land.
It doesn't get much better than the black and white Andy Griffith shows when Barney was in 'em and Gunsmoke. Too bad they didn't make more of them, I can't stand to watch the same thing twice.

Bein' a Gunsmith the one Gunsmoke episode that really stuck out to me was when Doc and Matthew are transporting a prisioner on a train and some up-tight city-woman said something about guns being bad. Old Doc rode her up one side and down the other and told her something like "guns in the hands of good people like Marshall Dillon built this country and keep it safe and free enough for her to make stupid statements like that!"

I can't imagine a time when something like that would have been said on one of the most popular shows on TV!

I wish I'da lived back then.

 

The driven gear that I removed is slanted ////. Thanks for the info! I'll be back at the dealer this morning.

 

LOL...well you sure don't want DOAZ17271B, because it's slanted \\\\ and if installed...will be chewed up in a NY minute by your drive gear.

What dealer in CA is this? I can look and see (by the Ford parts locater system) if they have the 17T gear in stock.

 

Wayne was originally offered the Matt Dillon role in Gunsmoke. He was also involved in Arness getting the role.

Arness appeared in Wagon Master in 1950, a Ford film starring Ward Bond, Harry Carey Jr. and everyone's favorite cowboy actor Ben Johnson.

Arness was in the Wayne film Big Jim McLain in 1952.

Ward Bond and Marion Michael Morrison were football teammates at USC in the 1920's.

In 1931, Morrison starred in the Fox Production of The Big Trail. The director, Raoul Walsh changed Morrison's name to Wayne after "Mad" Anthony Wayne.

No one who knew Wayne called him John. He was "Duke" to all his friends, a nickname he got as a kid...from his dog! That's right, his dog was named Duke.

The original Gunsmoke episodes were 60 minutes long and were in B&W, then for several years they were 90 minutes long...some were B&W, some were in color.

After a while the show returned to the 60 minute format.

The show was on CBS from day one, and came on at 10PM here on the west coast. In 1958, Have Gun Will Travel (Richard Boone as Paladin) was introduced at 9:30 PM.

If you ever watch the opening sequences of this show...you will see that Paladin was the slooowest gun in the west.

Boone was scared to death of horses! Most times, stuntmen did all the riding.

You like westerns and are a gunsmith? That's a great combination, I know quite a few guys like you. Check out my "About Me" info to see why.

 

I haven't seen any of the B&W episodes and none of the 90 min. ones either, unless they were VERY cleverly edited down to 45 min or so with 15 min. of commercial added and I didn't notice the difference. That seems an impossibility to me, my guess is they never air those.

 

Just looked at your "about me" section. Looks like your my kinda' guy! You know in a MANLY-MAN sorta' way!

I heard that when JW turned down the role he recommended James Arness.

I could have swore I saw JA in a color JW movie from the '60s or so?
Any idea which it might have been? Im sure it wasn't one you mentioned. Also if I remember right he played a bad guy or at least an ill-tempered or cowardly guy. I think that because it was a contrast to the Matt Dillion character I was/am used to.

 

In Wagon Master, Arness played one of the bad guys.

Arness was also in Hondo and The Sea Chase, 50's films...both starring Wayne, but I haven't seen these films in years...so I don't recall what his roles were.

AFAIK, no network is running the 90 minute episodes of Gunsmoke. I've seen the early B&W's but where..I can't recall.

Most of these TV and old Western films I just can't watch anymore. Once one becomes a Old West & Firearms historian...watching shows like Gunsmoke, with the anachronistic 1950's cowboy hats, haircuts, Model 1892 Winchesters and 2nd generation SAA's look so way out of place.

Tombstone (1993) is prolly the most accurate western ever made as far as customes, leather and guns are concerned. Old West historian and actor Peter Sheryako who played 'Texas Jack' Vermillion also was the technical advisor for the film and provided not only the guns, but many of the extras.

The only firearm that is in-accurate is Doc Hollidays Model 1877 Colt Lightning DA revolver. It should have the Bulls-Eye ejector ****. It has the post 1883 half moon shaped ejector ****.

The film itself is almost total fabrication...like all Hollywood westerns were before and since.

The Costner film Wyatt Earp is somewhat more accurate...somewhat.

The major reason why all Earp films and TV shows are so in-accurate is...the biography published in 1931 on Wyatt Earp and written by Stuart N. Lake was almost total fabrication.

Lake interviewed Earp exactly once...for 15 minutes just a few weeks before he died. Most of what Lake wrote about Earp...he made up.

The best John Wayne western...IMO, was The Shootist which took place in 1901, so the costumes, leather and the '92 Winchesters and SAA's are accurate.

 

That's right, John Wayne turned down Gunsmoke and recommended James Arness.

Don't think there is a John Wayne movie I don't like, I have almost all on tape, many original. Jimmy Stewart is another I collect. I have over 200 westerns between the two.

I could never pick a favorite John Wayne movie, I like them all, Especially his Batjac Productions stuff.

-Enjoy
