Banks Differential Cover O-Ring is Too Long

[@christophercain7343]

They didn’t send you the wrong gasket. I work in the semiconductor industry and we use long thin O-rings all the time in high vacuum applications. We have the same issue with the O-rings, but only from the people who don’t know how to install them properly. Also you have to be very careful not to stretch the O-ring when you are handling it.

[@JeremyPrattigmp2u]

At least I know now that it's correct. My original impression was that it was wrong, from just being such a new product at the time and someone is putting in the wrong gaskets. Now I know it's just right and Banks has updated their documentation to eliminate confusion.

[@macbook802]

I work in the aerospace o-ring industry, we put ours in the microwave for 10 seconds to get them back down to size

[@xostler]

@@macbook802 What, cut it?! No don’t cut it lol. A static seal will do just fine for what he did. I’d bet OP was accidentally stretching it as he seated it into the gland. It’s easy to do on the irregular glands as you move along the perimeter. I get it’s non-critical and your solution would probably be fine, but it’s just extra steps. No need to do all that extra and risk damaging it more than you intended.

[@christophercain7343]

@@macbook802 that’s not necessary, squeezing the O-ring like how he did in the video is pretty much the best option. It makes the seal thicker too so that it seals better against both surfaces. Don’t ever cut the O-ring, and “don’t trust banks ever again” is completely nonsensical. The provided O-ring worked just fine, he was just installing it incorrectly. You should know this working in aerospace. I’ve never tried the microwave trick though, I’ll have to see if that works without hardening the rubber

Based on comments this video has helped others who has the same issue and prepared others for how it's done. If this even helped one person save a small headache then it was worth it.

[@fender42421]

@@JeremyPrattigmp2u the video is titled "Banks Differential Cover O-Ring is Too Long" and that is not a true statement and looks poorly for Banks. Do you not get that? I agree if no one has ever dealt with long skinny oddly curved and shaped gaskets then this is helpful for your first time. But the title is misleading and wrong. You have 118 subs lol, I know how it works, but why have such a clickbait title? which is not correct. Also parts departments of any kind the easiest way to help a customer is to agree with a customer concern and send them a knew one, especially if its not an over the counter in person deal. Because it happened a second time they probably figured well we know we sent him the right one he must not be doing it right but I just sell the parts i dont work on them, let me ask someone who knows. HOPE this now really sinks in for you. It is a helpful video for first time use with this style of gasket, who would have known stretching it to fit would make it longer rather than pushing it in to fit and seal. Title is still wrong towards banks and is just clickbait. Hope it blows up for you tho :) cheers

[@udonenomee2117]

I build RVs here in Elkhart. It’s the same principle as a weather seal. You don’t want it short or tight because when it’s cold it would be short or stretched. So we cut it long and compress it into the channel that allows it to slide and settle. I was doing whatever I needed to do to make it look good and then I was taught the proper theory and technique needed to do it right. Everyone saying you stretched it either hasn’t learned the lesson about shrinkage or has a mental shortcoming. If I kept stretching it to fit and crimping it into place, then when it is sent to a freezing place it will shrink so much it could pull away and leave a gap at the corner.

[@JeremyPrattigmp2u]

Thanks. Humanity is interesting when it comes out on the internet. I've seen this with my RV, what you're saying with the weather trim being too short or long. I was replying to every single message on this and stopped except for the worthy ones.

Yeah, some can be difficult. I find that actually pushing the material together, bunching it up so to speak, will adjust its overall length. It also adds thickness.

Yes , I generally do a pass in the opposite direction to make sure it's de stretched and situated.

[@bobjoatmon1993]

A lot of auto parts stores sell an o-ring splice / joining kit. If compressing it still leaves it to long you cut it on a slant, not straight across and measuring carefully, cut out the extra with the EXACT same slant and glue them together. Put the splice at the top. I've used this on automotive, marine and authorized aircraft repair, it's an approved method for oil sumps and covers (not pressurized)

[@MrTheHillfolk]

3m makes an excellent "flexible crazy glue" but a bottle is around 40$. Still worth it for other rubber goods. The kits are a piece of O ring and some crazy glue,and the glue always dries up first 😂

[@The_Vaporizer]

NEVER EVER CUT AN O RING!!

[@bobjoatmon1993]

@@The_Vaporizer you obviously are not a professional equipment maintenance and repair person or you'd know that it's very common to cut oversize O-rings (if it has the right cross-section of course) and glue them together. In my 40 years as either a millwright or aircraft mechanic (both Airframe & Powerplant) I've done it a thousand times. I've recieved overhaul kits from both European, Asian and American companies that didn't even have any o-rings, just a spool of the correct cross section, compound and durometer material to make the orings for the equipment and sometimes even a cutting / glueing jig with, of course, their preferred glue. Some are cut square but most are cut on a diagonal. The only ones that can't be cut and glued are the Teflon (PTFE) or PP / PE ones. So maybe you learned something today.

[@Photosynthesisbeing]

Anyone who works in the vacuum chamber for semi conductors can show you how to do this easy. Make sure you use a silicon grease, bead it in but make sure to create little humps along the way. These humps are then pushed down with one finger once the whole o ring is snug. Also everyone knows your asking for a leak if you cut it.

If you ever have an o-ring that actually is too big, on an application where that O-ring doesn’t have to stretch around anything, where it’s being used in the same fashion as your diff cover, you can actually cut them and crazy glue the ends back together. It’s a step that is used only when there is no other option though.

Yep you should think of an o-ring like a rubber band if you stretch a rubber band what happens its diameter gets smaller so of course when applying an o-ring same thing you want a good thick diameter for maximum contact to the two mating surfaces it also allows for shrinkage to not be an issue as well from the heat

You know if you use a touch of dielectric grease to lube the rubber.. it kinda finds a happy place.. and prevents it from sticking or drying out over time. Or stretching as you install it.

[@frankm4611]

@@JeremyPrattigmp2uok gear oil then. Something that’s compatible with the nitrile rubber o allow it to relax with minimum friction into the grove and even the tension across.
