calling all Halibrand V8 Quickchange gurus, I have some questions....

Okay, so I have a friend that's running an orginal Halibrand V8 Culver City quickchange rearend in his '32 Roadster. It has 3:54 gears- built with a '40 Ford Banjo. So...my question is this-
After driving around on the freeway or town, is it normal for the Quickchange case to be hot? should it be or should it be cool or just warm? Everything seems to be fine, but the temperature on the case tends to be hot. The quickchange has been this way since he's owned it. It's been serviced/ rebuilt with all new pinion/ring gear/bearings a couple of times over the last few years as this roadster gets drivin alot. The lash is good, clearances right, etc. so just wondering what ya'lls experience has been with these rears? are they hot after running around? any info will be appreciated. thanks!

 

Hell yes they get hot. Just think of those streight cut spurr gears spinning like wild fire.

I used to volunteer to be the diver when we changed the spurrs in the Golden Rod 990 streamliner. Needed gloves to handle the cover and gears, even after the 20-30 minute tow back from the top end.

 

like rich said, they get hot! Even after a short heat race on a 1/4 mile track changing gears on my midget was not something you looked forward to. Always used a rag and had something handy to dump them into quick!

 

I think you got to remember these things were built for racing and primarily short oval tracks. Not to say they wont work, but putting one on the street comes with all sorts of consequences. They are still the "coolest" rear ends ever... LOL

 

I run the Winters version in my asphalt supermodified. Ditto the above posts about them getting hot.

I found that running Red Line Heavy Shockproof Gear Oil (yes that's the official name), made it run about 60 deg cooler. Make sure you are sitting down when you get the bill for a gallon!

Keep in mind that the alum (or mag) housings transfer heat much better than an iron or steel housing, so it's helping to keep the temp inside a little lower.

 

Aluminum also transfers heat A LOT quicker than steel or iron, therefore something that would normally "Feel" cool after a short run in the car, that was steel or iron, will typically feel hotter if its aluminum, since it conducts heat that much quicker.

 

hey thanks for the info guys! your input was very much appreciated!
