This week, we make more progress on our vintage dirt track race car. Davin sets out to assemble a vintage Frankland Quick Change rear end with fresh bearings and maybe a few "custom" pieces that he's not quite sure where they go. It's always an adventure when rebuilding somebody else's old project! Follow along as Davin takes us through the process of pressing (hammering?) in bearings and making sure everything is lubed up and torqued appropriately.

it's not a freezer that you need, its liquid nitrogen. It is not more difficult to contract than to expand, thermal expansion is pretty linear. It's just that the oven is 150+°C, the freezer is at best -20. Liquid nitrogen being -200, it would contract the thing as much as the oven expanded it.

I worked for Frankland Race Supply with Fred Bratchie building those rear ends. We just warmed up the housing with a torch for the pinion nose bearing. Drops right in. There is a seal for right side tube called a Seals-It, keeps gear lube from going to hub. The outer races I just used press to seat in place. There's an upgraded w piece nut for pinion to lock it in place. Gears are usually placed big on top small on bottom. We always checked gear swipe pattern and lash before final assembly. Used a dial type inch pound torque wrench and dial indicator for lash. great rear for dirt cars.

@joealbert7773 2 жыл бұрын

I've not done a Franklind, but I've have done a lot of Hallibrands. The support bearing on the pinion on a Hallibrand is a shrink fit in the case. The proper method is to heat the case with a rosebud torch and install the support bearing. You also assemble the pinion and bearings outside the case using and old quickchange gear to hold the pinion in a vise. This makes it much easier to tighten the pinion nut. Once you have the bearings assembled with the proper preload, you again heat the case with a rosebud torch and install the pinion and bearings as an assembly. I never used a gasket on the QC cover, but I did run Hallibrand.

the CLTE for general mild steel would max out at .00145" shrink over a 4" diameter so there would be no appreciable movement. You would need a 250F reduction from room temperature to shrink a 4" diameter by ~.007" to allow the press-fit to slide in.

@toddpfister280 2 жыл бұрын

A regular freezer will only get as cold as the outdoors during the winter so the bearing won't get cold enough for a loose tolerance. Otherwise the would fall out during the winter untill the warm up lol. You need to use dry ice to get anywhere. Good luck looks great.

I know this comment will get buried at the bottom...but for the mystery washer I think the location is right, but between it and the nut there should be a claw washer. @12:42 you can see one of the splines in the shaft goes all the way through the threads. @9:23 you can see witness marks on the inner diameter of the washer that suggest another washer was there and not the nut.

Be careful how hot you make the bearings, If the steel is turning that brown colour, you may be messing with the hardening/tempering. If it is just cooked grease that another thing.

We always did our Quick Change Gears the opposite of how you're doing it. The bottom change gear is the Drive Gear and the Top Gear is the Driven Gear. Big gear (Higher tooth count) "Fat Boy on Top" gives you a lower gear ratio (Higher Numerical). Fat Boy on the Bottom makes it a Higher (Numerically Lower) final drive ratio. I think with your 22 tooth gear on top and your 20 tooth on the bottom you will have a 5.34:1 ratio. Just check your numbers manually and remember that Fat Boy on Top is always a Lower Gear. We almost didn't qualify one night because we had no pull off of the corner and we weren't up in our RPM Band.

@Hogger280 2 жыл бұрын

Has to be a lot colder - try dousing it with freon or propane or if that offends you then pack it in dry ice. You can also warm the bore that the race goes into. Trick to remove a bearing race - arc weld a bead around the inside of the race - when it cools the race shrinks and will fall out.

@frostypop142 2 жыл бұрын

liquid Nitrogen is the correct way to apply thermal shrinkage for metal to fit, however dry ice usually works pretty well too, a standard freezer does not get any where near cold enough to cause any sort of thermal shrinkage.

In the freezer you're only dropping 50-60 degrees from air ambient compared to raising 200-250 above in the oven. I use a Fry Daddy filled with synthetic oil (higher burn temp). They are cheap and available. I agree about brass tools. I make punches with rebar. Softer than puppy poop and grippy with oily hands.

My opinion on heating a bearing vs freezing a bearing is that the item changes size a certain amount per degree, in either direction. You can easily enough heat the bearing by 200F over room temperature. You aren't gonna even get half that difference in a freezer, so of course it's not going to work as well.

@robertd5674 2 жыл бұрын

Killer build ! Love the out of the ordinary! On the heat and shrink topic. Yah a liquid nitrogen is cheap . However, a liquid ni dewer is very expensive . Upwards of 800-1000$ bucks. (Depends on where you get one) You can almost duplicate the nitrogen on the race install by freezing the race( as was done), then careful and thoughtful application of a mapp gas torch on the seat area of the axle tube. “Falls in” . Remember however , the smaller the items your dealing with, the less the amount of shrinking or expanding you’ll get for a given temperature. This is why ring gears on flywheels fall on so easily with just a small amount of heat.

One of the things we did while I was working on aircraft wheels was that 1st the bearing races had to be in the freezer for a minimum of 72 hours. This ensures that the whole race reaches the low temp you want. but we would also heat up the rim 1/2 in an oven to help. Considering your setup in the shop I realize that's not exactly feasible for these parts. But it's something you might want to keep in mind for other items. Just a thought. Maybe get a used full size electric stove to use the oven part for this?

@davidblalock9945 2 жыл бұрын

You have to be mindful of the delta. When you stick a the inner bearing assembly in the toaster oven, heat it to 400°, and the room temp in the shop is 68°, you have a delta of in excess of 300°. But in a freezer that’s 30°, and room temp is 68°, that delta is only 38°. To use the freeze method, you put the races in a pressure pot with about 5 lb of dry ice. Let the ice melt in the pressure pot till it’s liquid, them open the valve. Instant -200° bearing races.

Actually thermal expansion works the same way on either side, your temperature rangers were off, heating things up usually are done with a blow torch or oven, easily rising temps to (100+ C) 250+ degrees F, but a freezer will sit at (-4 C) 30 degrees F. So it didn’t get cold enough to really size down, try other methods of freezing like Dry ice or liquid nitrogen, that will more less be similar to heating up the metal. Also try both, freeze the insert and heat up whatever it’s getting inserted to!
