History Halibrand qc 2sp ?

Has anyone ever seen one of these or know anything about it ? Thank you

 

well i sure want to hear about it!!

 

I am with patsurf . I sure would like to hear about it.

 

Whatever that device is, it is mounted where the pinion gear p***es through the case. I don't know how that could make a 2 speed.

 

I really don't know much about them but if I recall that is an In/Out Hal.

 

Another older guy told me it was made for Indy type cars going in and out of the pits ???

 

This is the one I was thinking about, the lever location is different........don't know!

 

Looks like it could be the same principle though.....

 

Some place on the HAMB is a thread about Halibrand 2 speed rear ends. The search function ****s, you have to use the proper words or phrase. There was a story about Roger Ward showing up at a sports car race with his miget and they laughed at him with his in-out gearbox. He proceeded to show them the way home with his 2 speed rearend. Pat Warren in LA made a copy of the Halibrand quickchange rear and he devised his own 2sp gearcase that bolted to the rear of his and Halibrand's QC. I have one of his setups missing the mainshaft.

 

Can you post a photo ?

 

@redo32
Interesting ,, if I thinking correct
The 2 speed part ,
does it over drive or underdrive
Let say if you have the two gears set up for 4:00 What does it change to when
Engaged ?

 

@19Eddy30 there are different sets for different ratios. I don't have a chart.

 

That has a slider on the lower shaft so you can connect and disconnect the lower shaft. On sprint cars, it allows you to do away with your in and out box. With no in and out box, the front u-joint is bolted directly to the crank flange. That also means the torque tube can be longer (the length of the deleted in and out box)which is supposed to give you better forward traction.

 

That makes sense. The back gear housing has to be a bit deeper to accomodate the extra gears. So the gears on the lower shaft have to be retained by either a bushing or a bearing. The slider locks one or the other on the lower shaft.

I've always used Google, not the HAMB search function, include HAMB in your search, always (usually) gets results.

 

Thanks @DDDenny, I need to get into the habit of searching like that.

 

I wonder who could build one today ? Does anyone have any thoughts ?

 

kevin pharis!

 

Who is that ???

 

look on here about building a winfeld

 

Don't know what that is ?

 

I recall a youtube video about two speed quick changes. Can't find it now. They said that there only half a dozen 2 spd V8 versions made.

 

Interesting

 

To set the record straight, Ted Halibrand worked for Pat warren at Downey Machine as a pattern maker and copied the Pat Warren quick change when he left to start Halibrand Engineering. Not the other way around.

 

They both would be a good one never the less......

 

Cool. Thanks. I didn't know that.

 

I have a bare 2 speed Halibrand case for sale...
