Is a Halibrand quick change suppost to get hot after you have drove a little ways? I talked to a stock car friend and he says they do get hot. Mine is getting hot and I just wondered.
Im not sure how extreme the heat is, but my gramps told me they got hot when he raced with them, thats why they had to have some very good fluid in them. grease/fluid? im a bit ignorrant to what is used in them.
I found this quote on the internet at the bottom of the page. It's marketing, but there may be merrit to it, and it says to me that they are trying to reduce heat in the quick change as well. http://www.microblueracing.com/custom_shop/superfinishing.php "recently a gentleman called that runs in the Hooters series. Weve been running Royal Purple in our quick-change rear-end for years. This is the first time it has come back out purple! Im tellin you, we saw a 100 deg drop in oil temperature, honest (true story)."
I run a frankland q/c and it only gets warm to the touch . I use redline synthetic gear oil and have about twenty thousand miles on it now. 486 ring and pinion with a final drive of 367. If you have a locker or other diff. in it check for any stagger across the rear tires , this WILL create heat .
Well i have tried red line and royal purple products, and they are great great products, so if they have gear stuff for quick changes, id try it.
Yes my rearend is a locker I'm using just regular 80/90 gear oil no synthetic. Is it ok to run synthetic? So what weight gear oil is the best?
How many miles are on it? Who built it? Most QC builders will set the ring/pinion "tight" on a street car, 2-3 thou as opposed to a race rear which would be 4-6. The clearance will increase as the rear end heats up, so 2-3 though cold will be more like 6-8 hot. But, the tight clearance will make the ring/pinion wear a bit the first couple of hundred miles, which might create more heat. If this is a newly set up rear, it is normal to see some very fine metal flakes in the gear oil. Change the oil three or four times in th efirst hundred miles and it should disappear. Also, there is an adjustable "foot" that supports the ring under hard accelleration. Some builders will set it up a bit on th etight side and let it "wear in". This might also cause some additional heat. Honestly, in my opinion, is is probaly just fine. Most rear ends will run ambient air temprature plus 90 degrees F. So, on a warm day, 170 degrees is perfectly normal. 170 degrees would certianly feel "hot" but actually be perfectly fine. Keep an eye on the fluid, and if makes any odd noises. Other than that, don't worry about it. -Abone. here's my Frankland
Tell you what, drive any rear drive car you have for a while, Then jump out and lay down in the back and slap your hand on the back cover. You won't leave it there long. No big deal but all gear sets produce heat in operation some more than others.
Yes, Synthetic is better than petrolium based products in this application. Give Red Line Oil "shockproof 90 wt" a try. You'll notice a difference, www.redlineoil.com I also work for them. check us at www.donhudsonracing.com
