USA SD-70 MAC

Before removing the covers, stuff cardboard or foam between the top of the blocks and the frame to keep the motor blocks from dropping and dislodging the axles and their bushings. Unlike the axle bushings [O] in two axle motor blocks, the main axle bushings < O > in these blocks are rotated 90 degrees, tits up if you’ll pardon the expression. The smaller bushings [O] on the secondary shafts are not.



Keeping the motor blocks from flopping around is very important because there is a drive shaft between the main motor block and the floppy axle. If the shaft drops out of the U-joint, the top cover has to be removed and it’s a real bear to get the shaft back in and have it stay in.

There are two layers of gear shafts when you open the main block of the SD-70.



The bushings on the top set point up , the bushings on the bottom set are parallel to the edge of the block [o]. The bottom cover of the block has triangular indentations ^ that the top bushings fit into. If top bushings are rotated improperly [o], the cover will not close.

I never opened the floppy gearbox, as I was only trying to remove the sliders.

Most interesting Paul!

First I wondered how you got the "bracket img bracket" to show up in your post without having to resort to the embedded *asterisk* to keep "my" computer from trying to interpret it as a command? Is it because it is the last thing on the line? How'd you do that?

THEN, when I started to create this reply (and assumming I might see in the quoted text how you got the text to show), I note that the quoted display of your text shows the photo using the "img src=" encoding... indicating exactly what you said to remove and use the "bracket img bracket" encoding... which seemingly contradicts what you are saying. /DesktopModules/NTForums/themes/mls/emoticons/blink.gif

I was supposed to be a computer guru back in the day many years ago, but this internet stuff just gets sillier and sillier... I just can't quite figure it out anymore/DesktopModules/NTForums/themes/mls/emoticons/w00t.gif

You are right it should have just showed the dreaded box with the red X.

I think what went wrong with Barry’s post was the space between the opening bracket < and img. A small error like that is what can make writing HTML frustrating. Let’s remove the space and see what happens.



I taught myself HTML by buying the book “Creating Web Pages for Dummies” and writing test code. On our club web site there is a page “Work in Progress” set up just for this purpose.

Our web site also has both WYSIWYG and HTML Editors built in by the service provider editme.com. You can throw plain text in the WYSIWYG Editor; format it using formatting icons; and toggle to the HTML editor to see how it is formatted. I saved examples in an e-mail folder called Templates, and refer to them when I get stuck posting. I now write my web site articles using Word with the HTML tags included. I always feel rushed when I am on-line, and Word has a grammar and spelling checker.

I know this picture is huge but me being able to post pictures after all this time is also hue. Thanks Paul for the help. This picture was taken along the Rim of the World scenic bypass in Los Angeles County when I was out there a couple of weeks ago. This is the real BNSF and I considered myself fortunate to have seen this train and getting to photogragh it
