Cat 621 info
 

Hi, I am new to forum, have done some scale ic engine builds, I would like to build from scratch a Cat 621 scraper in 1:14 scale. I have searched the web for pictures and drawings, found a few but what I need is a picture or drawing of the complete frame (tractor and bowl). Any ideas?
Thanks
Terry

Get yourself a parts manual , thats a big help . Also search the net for 621specs. . I think Richie Brothers has a equipment spec. site . the cats should be easy to get that info on . Have fun and welcome to the scraper building club . can't wait to see it started :D .

Look on ebay and buy an old NZG Cat 621 scraper. You should be able to get the lines you'll need but not all the internal details. I know a dual Sabertooth will simplify the steering.

This may help. It is for the elevateor version J621 but the tractor unit is the same as the open bowl 621. Hope the dimensions help

Thanks for the suggestions and the drawing, I have ordered a parts manual on ebay, will give that a try.

Try this link, which has a lot of old spec sheets, although I couldn't see one for the 621.

Hi Terry. Welcome to the forum. This link will take you to the Cat website for the 621. To bad this one doesn't have a decent drawing as we usually just scan it and have it enlarged to the size you need. Might find you 1/2 or 3/4 square at home depot or Metal supermarket. Hope this helps. Rob

Thanks steamer, I did download and print this one, what I need is a bare frame picture to scale, not much construction going on around here or I would go hunting with my camera.
