Several years ago I replied to a thread....http://www.jalopyjournal.com/forum/showthread.php?t=73309&highlight=welded+quickchange I had recently aquired a Bridgeport mill and a lathe and wanted to know how they made quick change rear ends before they were available from Halibrand.....Fast forward to recently and a clever fellow on here (there are several) displayed his talents and showed the quickie that he's building. http://www.jalopyjournal.com/forum/showthread.php?t=415472&highlight=welded+quickchangeOld Guy is his handle . His craftsmanship and detail sparked my interest again in making a quickchange for myself. I have actually been thinking this one through and collecting parts to try and do it myself. A good friend had started to build one but never finished it. He gave me what he had and after reading Old Guy's thread I got at it. I printed off every picture of a welded rear end that I could find and hunted through my old bearing book for the right bearings. Like Old Guy I don't have a staff photographer and to stop and take pics every time I did something ......well it just don't happen. So, here's where I'm at as of this moment. ...
Great stuff. Can you give us some info on the build? Did you make the gear enclosure yourself or is it available somewhere? Type of bearings and shafts? Anything you can offer up? You guys on the HAMB amaze me with your skill sets! This is the best Hot Rod site there is!
How are you going to attach the new pieces to the original housing? (Weld, I know, but...) Is the housing cast? r
I just need to subscribe to every thread you do Jethro! I have that CR catalog, good reading for a gearhead. Can you post #'s
My guess is that the ideal candidate for the new long input shaft under the crownwheel would have been a piece of the original torque tube drive shaft, as it already has the correct six splines on one end to take the new driving gear. Then the other end of this would just need machining to take the yolk from an open shaft. Also using this piece of shaft would ensure that the steel would be of the appropriate grade to accept the loading. Am I any where near the mark with this? Great thread by the way. I will be following this with great interest. My Q/C is currently away being put together ready for my car. I can't wait to get it all back!
The gear enclosure is a piece of 6 inch .250 wall tube split in half and welded to some 1/4 plate to make the oval shape. The back gear plate is 5/8 thick. The shaft is cut down and rewelded driveshaft . I turned down the end to accept the support bearing. Lets see if everything fits together and works first.....I'll post a parts list if it turns out
Looks like a great start. The rear spur gear case is done the same way as mine was. Have you seen this thread ? http://www.jalopyjournal.com/forum/showthread.php?t=131240 I will be following this thread with interest... '22
Yeah that's pretty much the one I copied...between you , Old Guy and a few others I may glean enough info to pull this off!
This is " the stuff legends are made of " ! One of the reasons I joined here,unlike some of the recent o.t. and non traditional crap you see more & more of on here !
WOW! I'm impressed that you have a workbench that clean! LOL, I can't even find mine...Awsome work, hat's off. Brian
From Mar. '99 SR Mag. I would very much like to do one of these myself. Jethro-- I'm not far from you. Like to see your project if and when you do this.
C'mon over when you're in town......bring that article too.....I wanna see if I'm going in the right direction......Where in the Shuswap are you from?
