Barry, how's it coming?

One of the criteria I had for the new gearbox was not to lose the slow speed running that the Connie gave us, it is absolutely marvelous. After a few early runs I asked Dave if the slow running was still there, he said it was. That was all I needed to hear.

Question, I would like to post some pics of the progress on the gear box. I have never learned how this is done. Is there a location on this site which explains how to do it?

Spent the day making blanks of the gearbox main body. Then drilled a few. I am so pleased with the gear mesh, I wanted to check it again. Discovered the axle gear set to far off center, gear rubs on the side of the gearbox. Now will have to make a new blank for the bottom of the gear box. My work for tomorrow is cut out for me.

There are five pieces which make up the gearbox; 1. The main body, 2 The upper cover, 3 The lower cover, 4 The top cover, and 5. The axle cover. I want to show these pieces, then with the gears in place, add the motor, add a dummy axle. Show how it goes together, show all of the ball bearings, every shaft and the axle too.

Cale,

Thank you. I guess the worst case is to email pics to someone and have them post for me. Although, if it is not too involved I would be willing to post myself.

Regardless, tomorrow is not a good day for extra-curricular activities. I must get the main body bottom plate redone.

Thursday, I have a Doctor’s appointment at 1:00.

Dear Barry,

Are the “Big Hauler conversion to 2-8-0” chassis and the “Connie replacement” chassis the same item?

Sincerely,

Joe Satnik

Gee, I’ve got one that looks just like it from Bachmann. :lol:

Joe,

The Connie Gear box is a complete departure from the Big Hauler “solution”.

I am replacing the Bachmann/Connie gearbox and motor with a gearbox of my own design and a new Pittman motor. The gears are heavier, just as have been used in the Big Hauler conversions, same gears. Brass worm, Acetal worm gear with brass hub, aluminum spur gear, driving two acetal gears with brass hubs, one as an idler, the second is the axle gear. All of these spur and worm gears have a 3/16" face, all gears’ shafts are in ball bearings, the motor is ball-bearing. The shafts are stainles steel as is all of the hardware; nuts, bolts, set screws, etc.

Just as a note, I haven’t had a gear failure, to my knowledge, for more than 5 years. Previously, there were some meshing problems.

Geoff,

Thanks for the instructions to post pics. Hopefully I’ll give it a whirl this evening.
Now, lunch and then back to the shop.

Here’s a stoopid question:

She’ll still have the counter-weights on the drivers, right?

Anudder question:

I would like mine without any electrical pickup. Just two good wires from the Pittman sticking up out of the gearbox.

#50

John,

Yes, we’ll still have the counterweights. The only thing I do with the axle is tell you how to prep it for a new gear and ball bearings. There will be no wires coming from the gearbox, the motor is too big to be in the gear box.
I have pics from today’s “work”. I am going to try and post them. If I can get that much done, I’ll try to explain what you are seeing.

I did get the main body drill jig corrected.

#51

OK,
Then in mine I don’t need brushes, and all the track power stuff.

Also, I’ve lost a couple of the tiny springs that looks like they are part of the suspension for the axles.
We won’t need any of that crap either, right?

#52

John,

I am back from the Doctor’s office.

You are right, but do not remove the brushes and go find those springs. This may be the best suspended (as in suspension) locomotive in the hobby. There are four springs per axle, two for pickup and two for added suspension pressure. Very Important, actually more so once the new motor and gearbox are installed.

Dave (TOC) reported on the original test unit, that pulling 14 cars up a 4% grade on R/C he could actually accelerate up the grade. I gathered that there wasn’t much else that he had that could equal that performance.

Geoff is going to help me, I have 12 pics uploaded to My Files. Have to figure out how to download into a message.

There is a little tightness in the drive I assembled, so I have to check out and see what is causing that issue.

When you are in the message editor just click on My Files, pick the photo you want and drag it into the message. You will see some text like [code]

Crap!
I have no idea were they sproinged off to.
So I removed all of them.
I’ll re-spring it with new after market springs.

Sorry about this but I have been helping Barry so he can post pictures. Besides I really like this loco.

This is the motor and gearbox installed in the chassis, obviously without the boiler/cab assembly.

(http://www.lscdata.com/users/barry_-_bbt/_forumfiles/Connie%20BBT%20Gearbox%20004.jpg)

This is the gearbox main body part. The drill jig is the aluminum assy you see here.

More of the main body. The lower picture shows the bottom of the gearbox main body

More of the Main body, rotated again.

On the left is the Top Cover and the main body with motor and the sidecover in front.

This is a view of the lower cover and the tool which drills 3 holes in it.

This shows the drill jig for the upper cover.

(http://www.lscdata.com/users/barry_-_bbt/_forumfiles/Connie%20BBT%20Gearbox%20011.jpg)

This is the bottom cover and the drill jig to drill the two mounting holes. This piece has also been machined to give it an overall .093" (3/32") thickness.

This is a view of the Bachmann Connie axle fitted with the original gear.

(http://www.lscdata.com/users/barry_-_bbt/_forumfiles/Connie%20Gearbox%20-%202%20014.jpg)

Here is just the axle assembly with the new gear. Any questions, let me know. Barry - BBT

#58

Barry,
That looks fantastic as usual.
There doesn’t seem to be any quartering on the new axle so I don’t understand how the new axle actually drives the wheels.

Do you have any step by step pics of removing the old gearbox, with how the wheels etc are mounted on the new gearbox and drive shaft?

#59

Tony,
the plain axle shown is merely a jig tool. The drive uses the original axle with a newly designed final drive gear. Quote from a previous post response from Barry -

         "The only thing I do with the axle is tell you how to prep it for a new gear and ball bearings."

OK.

Thanks Tim.
