I did a search and the answer is not in anything I could find. I have a new (100 miles) Winters V8 with aluminum side bells and helical cut rear gears. I drove the car for 100 miles and the noise kept getting louder and by the time I got back home I had a headache. My question is, "Are the helical cut gears supposed to be really loud also?" I read on one thread about some type of spacer to prevent the gears from contacting the rear cover but Winters did not send any or recommend any in their instruction sheet. I love the looks but in a 32 sedan hiboy the noise will drive you to pull over and have a look at the rear end. I took the rear cover off today and could find no marks or indications of metal shavings. I would like to drive to Louisville in the car but I am afraid of damaging the QC. Has anyone had this experience with excessive noise with helical cut gears? Any suggestions would be welcome.
Thats the beauty of em. Sounds like a gear drive coming from the rear end. Straight cut gears will whine too but not as bad. Wait a minute I think I got that backwards. You've already got the quiet gears
did anyone do the preload and backlash on the pinion and ringgear? thicker gear lube 140 wt mine were never noisy in the racecars, but the noise was overpowering
Do you have another set of gears? change them out and see if it still sounds the same. If the gear cover has the bearings in it check and make sure there isnt a problem there.
It shouldn't be noisy at all ! I would check to make sure your have lube in both area. The gears have a separate oil chamber. The two plugs on the rear cover is where you fill it. Pump the lube in until it begins to run out from the other plug, then install both plugs. Also give Winters a call.......... good luck
Thanks for all of the help. The unit is brand new from Winters and has all the lube in the proper places so maybe my expectations are higher than normal for less noise. I will contact Winters Tech tomorrow.
Try 600W Rear End Oil `09-`48 Ford, @ Mac's Antique Auto Parts 1-800-777-0948. It Will Work. Or Try S.T.P. It Will Also Work. Good Luck,
Pewsplace, That rear end with helical gears should be very quiet. Winters does sell a shim kit that should be used with the helical gears. The change gears should not have much end play when the cover is on. We set them up with .005-.015 inch end play.
The Winters tech suggested the same thing and is bringing a shim kit to Louisville. Thanks for you response. I think anyone using this set up should install the shim kit prior to driving the car. They are working on a new set of gears to help reduce noise for the street.
Are you going to drive it back there? Is there anyway you could shim it before the drive? If it's not shimmed, those gears are going to want to walk back and forth on the pinion and lower shaft every time you accel and decel.
My Winters has helical spur gears. Shim them puppies and ya won't know that its a Q-C. Very little noise. Winters tech helped me out with my questions. Have the parts shipped to you. You will be a happy camper.
Yes, the shims are on their way. Thanks again for all of your assistance. The HAMB is the greatest. Lynn
Remember with the Helical gears they are trying to push away from one another! If you put alot of power to it it will blow the rear cover off!! JS
Bullshit.... We have run helical gears in our dirt cars for years with 700+hp. We beat the shit out of them. If you blow the cover off, something is BAD wrong.
this is great info, I recently purchased a new QC with old style bells (all new Winters 9" stuff and Dutchman axles...).. going in my Modified.. I have straight cut gears right now but will probably want to go Heli after I take it on a long drive..
I have 3 quick change rear ends in my present cars, 2 Winters, V8's and a original Halibrand champ. What I learned about spur gear noise is this. The first set I bought made so much noise I couldn't stand it. My dad told me to by 3 sets of the same ratio. Sure enough every set was different. It's all about the clearance between the gears, so when they make them they have tolerances. Then you have to deal with the tolerances between the pinion shaft center line and the main shaft center line. All of mine are quiet.
Yes this is an old thread however I remembered this question and wanted to correct the incorrect impression it gives. Yes there are two cavities. But NO, you do not have to put oil into the rear cavity with the spur gears. If the oil is at the proper level it will flow back into the spur gear cavity on it's own because the lower pinion shaft bearing is a shielded, not sealed bearing and oil flows back to the spur gear cavity on its own. 2 3/4 quarts is what the Winters quick changes hold.
I think the Winters QC (heavy duty, Champianship version) in my 54 Stude wagon is actually getting a little quieter..! Only have about 1200 miles on it, with straight cut gears. Even under a load, it doesn't seem as loud as it was at...say, 750 miles. Maybe the gears are smoothing (polishing themselves) up a bit. Unfortunatly, the car hides the axle housing. You have to get down on your hands and knees to see it...! Mike
Wonder what Lynn at Pew's Place found with his original dilemma. The last time I went to the oval track races, I noticed that the rear ends were much quieter than a few years ago. I'm sure that the gears (both ring and pinion and change gears) are better than they used to be. Also, the rem surface finishes are bound to be quieter. The gear lube has to be chosen to be compatible with the differential, different types require different lube. The gears really don't care.
I replaced my change gears with helical. Super quiet for about 10K miles but then I noticed a growling noise. Upon checking I discovered the rear cover bearings were worn. When I called Winters they asked if I installed the spacer and shim kit. I knew nothing about the shims, they said nothing when I ordered the helical gears originally. After installing the new bearings and shim kit it's quiet again. If winters had told me about the shims it would have saved me some down time and a lot of worry.
