I have been working on a Winters QC problem with a friend of mine in Detroit. Â He has a brand new Winters V8 model with less than a hundred miles of use and it is very, very noisy. Â He installed the helical cut gears and everything seemed to go perfectly until he went down the road. Â The more he drove the louder the noise became. He returned home and called me for some advice. Â My first impression was that the helical cut rear gears are walking toward the rear of the case and making contact. Â Winters sells a shim kit to keep the gears from walking but he did not install any shims in his unit. Â I asked the folks on the HAMB to respond and received a lot of useful information. Larry wanted to drive the car to Louisville tomorrow but didn’t want to ruin the expensive case and I don’t blame him.
He contacted Winters and they told him the shim kit may help the problem but the noise is normal even with helical cut gears. Â I have owned several quickchanges and they were all very noisy even with helical cut gears. Â The good news is Winters is working on some new gears to reduce the noise. Â The price we pay for the “Look” is sometimes worth it when you are young but at my age I can’t stand the heavy noise of the quickchange in a coupe or sedan. Â I hope the shim kit does the job as Lucy has an old noisy in her backside.
This is your basic Winters V8 quickchange for use with 40 Ford axle tubes. Â The differential is a posi and very tight.
Here is where the noise comes from. Â The spur or helical cut gears fit over the shafts and provide the proper ratio for your driving event. Â Winters sells a shim kit to keep the gears from walking into the rear cover. Â The Hot Rod Works recommends a .005 – .015 clearance from the rear cover. Â This will prolong the life of the rear cover and bearings.
Here is the rear cover with the bearings installed. Â If the gears walk they will soon tear up the bearings and cover.
One style is to use the early Ford housings bolted to the new center section from Winters. Â A Classic design.
If you can’t stand the noise then this is what you need. Â The no-change QC center section works and looks great. Winters makes a complete unit ready to bolt in your chassis.
This is a NOS Halibrand V8 unit with the straight cut gears. Â Noisy but correct for the look and sound of yesteryear.
This is my style for a true hot rod. Â Bob O has a Culver City unit going in his Model A coupe.
Winters has a complete unit with tapered housings ready to bolt in you chassis. Â This saves a lot of work but is not cheap.
Larry has this style Winters with the aluminum bells. Â I like these units also.
Today’s Classic Quickchange….Dreaming!
John likes his cars and the roadster with the QC peeking out spells early hot rod to me. Â The Cobra is for the Ferrrai’s on PCH.
