Video Transcript for Review of ABS Fasteners 1-3/4 Castle Nut Cotter Pin - 165649

Hi there, I'm Michael with etrailer.com. Today we're gonna take a quick look at this one eighth of an inch cotter pin. This is going to help to secure your castle nut, so that you don't have to worry about that castle nut coming off. So each arm of this pin is about one sixteenth of an inch, so when you have them combined there, it is gonna be one eighth of an inch. As far as our length goes, our overall measurement, we're looking at right two and a quarter of an inch there. Our usable length from the inside of that bend to the shorter arm, is going to be right at, call it one and three quarters of an inch.

So this is going to be made of a rough steel construction so it should do a really good job for you making sure that castle nut stays in place so that you don't have to worry about that coming off. So if you are needing a replacement one eighth inch thick cotter pin, this is going to do a great job for you. You are just gonna get the one pin with this part number so if you need multiple, obviously just increase your quantity. So that's gonna complete our look for today. Again, I'm Michael with etrailer.com, thanks for watching..

Just repacked bearings with new seals on my 4' x 8' folding utility trailer. Customer service was great in helping me with selecting the right parts including cotter pins. All is good now. I have been ordering from etrailer for 10 + years. Great place with great people!

Well I'm sorry to inform you that when I opened the box. I had a left kit, a right kit and an empty bag. After looking in the box closer under the flaps I found a washer and a nut. That was all.

Roger was so helpful in putting together a complete bearing kit from parts. Not many other places would take the time to sort out all the parts that normally come in a kit, that was unavailable. The OTER GUYS just tell you, sorry "supply chain issues-nothing I can do" I highly recommend etrailer. Ive been doing business with them over 10 years.

Not much to say about cotter pins! Saved me a trip to the auto parts store!

Nice upgrade of the axle on my [online] trailer. I had no confidence towing my home made teardrop camper until I installed this axle. The package was damaged in shipping and eTrailer quickly replaced the missing parts.

It’s a cotter pin. The correct one for axle crown nuts.

Great product, fast shipping! The brakes are perfect for our Airstream; I only wish that I spent the extra for self adjusting brakes

Wrapping up a weekend with friends, three hours from home on a lone forest road.. Going through my 'preflight walkaround' I notice grease splayed from the hub cap of one of the wheels, long story short, both wheel bearings had failed, and the hub won't come off. Had to leave the trailer on a forest road till parts could be procured, I wasn't happy about this as I just added about 3k of electronics i.e. solar, inverter, dc-dc, etc.. I searched for the parts I needed and called etrailer to see if shipping could be expedited, Paula S was incredibly helpful and seemed to share my concern. My expectation was to have parts on Thursday, maybe Wednesday, but the etrailer tracking email said Tuesday! I was skeptical, but ok, ill start transfeering almost every tool in the garage to my truck for the rescue mission... I was ready when the UPS truck pulled up at 5pm, 8pm I was on site, wrapped up and had my baby back home by 2am. Couldn't be happier, you've earned a dedicated customer. And, thank you for using UPS for shipping, while other shipping companies are complaining of labor shortages amd delays they came through as advertised, couldn't believe it to be honest. Paula S, the etrailer team and UPS, thank you!

Made in USA - Dexter rotor’s & disc pads - definitely fit my truck

Cotter pins, they are what they are. These are the right size and impossible to find in my neck of the woods.

I like that they are just the right size since most stores go from 1-1/2" long straight up to 2" long. I could not find 1-3/4" long cotter pins anywhere.

etrailer has them for low enough price that I stocked up so that I always have enough on hand.


Comments
Cotter pins have held up fine they are the exact right size and they are still in great shape when I repacked bearings the following year.

  • Can I Use the Dexter Cotter Pin on a Lippert Axle
    The Cotter Pin # 165649 can be used on a Lippert axle, so as long as you're replacing a cotter pin with a 1/8" diameter and 1-3/4" of usable space, this will work just fine for you. If your pin has different dimensions, just let me know what you're looking for and I can help you locate a replacement.

  • What is the Torque Rating for an Equalizer Bolt
    Equalizer bolts, like the TruRyde Wet Equalizer Bolt, # TRFA71063, should be torqued to yield. Equalizer bolts are not given a specific torque rating because they should allow some movement of the equalizer. If they are torqued down too tight, the equalizer will have difficulty moving and that could bind up your trailers suspension. Simply tighten the bolts down until they are tight, but still allow the equalizer to move. Keep in mind, the cotter pin is not included with this bolt. The...

  • What Size Cotter Pin is Used with Replacement Axle Bolt Kit for Yakima Rack and Roll Trailers
    I went out to the warehouse and pulled Replacement Axle Bolt Kit # Y8880180 to measure the cotter pin in the kit. The pin is approximately 0.11 inches thick whereas the hole is just slightly larger than 0.125 inches (1/8). The pin has an overall length of 1.64 inches. For a replacement you could use # 165649.

  • Torque Specs for Axle Spindle Nut, Suspension Hanger Bolts, and Lug Nuts for Trailer
    It looks like you might be asking about a few different torque specs so I'll address all of them separately. For a trailer axle spindle nut like part # 165686 you will need to run the spindle nut down until there is no more side-to-side play in the hub and then back it off to the next notch so you can secure the cotter pin, like part # 165649, through the spindle. When it comes to hanger bolts like the Redline # 166081 there isn't a specific torque rating either as you just need to make...

    We have the cotter pin part # 165649 which would work great with the Convert-A-Ball Interchangeable Ball Set # 900B. This pin is a standard cotter pin like what the ball set uses.

  • Correct Spindle Nut, Washer, and Cotter Pin for 7/8 Inch Diameter Spindle
    Yes, the Washer Spindle Tongue part # 165863 will work with 7/8" diameter spindles. If you also need the castle nut and cotter pin as well we have these available as part # 165931 and part # 165649.

  • Where Does Flat Washer Go
    I was unable to find an order number so I'm not certain exactly what you are referring to, but in general a flat washer such as Washer For 1" Spindle # SW1000 will go between the outer bearing of your hub and the nut that holds it on, which essentially works to protect the bearing. These washers are used on spindles with a spindle nut such as Spindle Nut 1" # 165686 and Cotter Pin # 165649.

  • Correct Replacement Castle Nut, Cotter Pin, and Washer for Trailer with 1" Round Spindle
    The correct replacement castle nut, cotter pin, and washer for a trailer with 1" round spindle is as follows: Castle Nut part # 165686, Cotter Pin part # 165649, and Washer part # SW1000. Unfortunately, we can't cross-reference trailer mfg. part numbers but the above parts are fairly standardized so there will be no issues with compatibility.

  • Cotter Pin Replacement Part for 5,200 lb Axles

  • Spindle Nut Recommendation for a 3,500 lb Axle
    Since you have a 3,500 lb axle most likely the diameter of the threaded portion of the spindle is 1 inch. You will need to verify that. And since the spindle has a hole in it for a cotter pin you would need a castle nut. For that I would recommend the Trailer Spindle Nut # 165686. For a compatible cotter pin I would recommend the Cotter Pin part # 165649. The Spindle Nut Kit # RG05-100 that you referenced is for a different style spindle so I would not recommend it for you.

  • Spindle Nut Kit Recommendation for a Dexter 6k Axle
    Since the D60 Dexter Axle uses a cotter pin and castle nut the # RG05-100 would not be the correct kit for you. For that I would recommend the Trailer Spindle Nut # 165686. For a compatible cotter pin I would recommend the Cotter Pin part # 165649. People use channel locks typically for installation and removal of these castle nuts since they don't really get torqued down and the length of the spindle prevents most standard sockets from being easily used.

  • Recommended Axle/Spindle Nut for a #84 Spindle.
    We have exactly what yo need! If your axle has EZ lube hubs with a grease zerk on the end of it use the Spindle Nut Kit for EZ Lube Axles part # RG05-100. This kit has the washer, nut and keeper for both sides. For non EZ lube hubs use the Trailer Spindle Nut 1" part # 165686. This is just the nut so grab the amount you'll need and if you don't have them on hand pick up the same number of these Cotter Pin, 1/8" x 1-3/4" part # 165649

  • Replacement Axle Nut for 3500 lb Boat Trailer Axles
    We have what you need! For EZ-Lube axles which are very common on boat trailers you want to use the Spindle Nut Kit for EZ Lube Axles part # RG05-100. This will have two nuts, washers and keepers. For the non EZ-Lube axles use the Trailer Spindle Nut 1" part # 165686 and the Cotter Pin part # 165649. these are individual so you will want two of each to have all you need. You can confirm these will fit on your axles by measuring your spindle and ensuring that your it has 1" threads on it.

    The bearings your Lippert 5,200 lb axle has are part # LM67048 and # 25580 and the grease seal is # RG06-070. For a cotter pin you'd need just the # 165649.

  • How To Use Bearing Kit for #84 Spindle with Round Spindle
    In regards to the Bearing Kit for #84 Spindle part # BK2-100, if you have a round spindle you'd simply reuse the flat washer and spindle nut that was already on the axle. If you need them we do offer them as the Trailer Spindle Nut part # 165686, the Washer part # SW1000, and Cotter Pin part # 165649.

  • Relocating Trailer Spare Tire Below A-Frame Of a 2020 Coachmen Apex Travel Trailer
    I have a couple options for you to consider. The first is the Fulton Economy Spare Tire Carrier # FETCLB0201 which works with 4 lug and 5 lug wheels and trailer frames up to 3" wide. This would make the tire sit offset on your A-frame. It will be harder to put on and remove the spare when that time comes due to the style of the carrier. I feel the Lippert Spare Tire Winch # LC159056 is your best option for usability. This will allow you to mount the winch on your frame and easily raise...

  • Recommended Spindle Nut and Washer To Use With Bearing Kit for #84 Spindles
    If you have Dexter EZ-Lube Axles, the Spindle Nut Kit for EZ Lube Axles part # RG05-100 is what you need most likely. Otherwise, the Trailer Spindle Nut 1" part # 165686 along with the Cotter Pin part # 165649 is likely all you need. The Bearing Kit for #84 Spindles part # BK2-100 does come with a tang washer already.

  • Spindle Nut for Use with Trailer Hub # AKIHUB-545-2-LF-2K
    For a spindle nut to use with the hub # AKIHUB-545-2-LF-2K that you referenced the part # 165686 would be a great replacement. You'd also need a cotter pin if you didn't have one as well with # 165649.

  • Is there a Torque Spec for Installation of Castle Nut on 2,000 lb Axle?
    The castle nuts do not have a torque spec. Bearings and races are fit to the spindle precisely and will have minimal movement to the washer and castle nut which will simply be tightened and held in place with the cotter pin # 165649. We recommend tightening until the nut stops without added force and then backing it off one notch to fit the castle nut. The Dexter Trailer Idler Hub Assembly for 2,000-lb Axles - 4 on 4 - L44649 Bearings # 8-91-05UC1 is a fit for 1.063 inch spindles and...

  • Can Races and Cotter Pins Be Added to the Bearing Kit for 3,500 lbs Axles
    The Bearing Kit for 3,500 lbs Axles part # DBRKHW35EZ does not come with any races but you can add the ones you need using part # L44610 and part # L68111. For the cotter pins you can use part # 165649.

  • Which Cotter Pins Does Bearing Kit BK2-100 Use?
    I would be happy to help! First for extra cotter pins you will need the # 165649 which is what the # BK2-100 uses. I tried to cross reference the 680387 but it did not reference to any of the grease seals. The # BK2-100 includes a grease seal that has an I.D. of 1.719" and an O.D. of 2.565". You will need to use digital calipers like # PTW80157 to measure the spindle and hub of your Airstream to confirm which size grease seal you will need. If you find you need a different size grease...

  • Do Trailer Hub Assemblies Come Assembled, Greased and Ready for Installation
    The Trailer Hub Assembly - 2,000 lbs Axles - 4 on 4, item # 8-91-05UC1, does not come assembled. You will need to work grease into the bearings and hub and clean the spindle on your trailer before installation. You will also have to install the seal in the back side of the hub once the inner bearing is greased and installed. I like to use a small piece of 2X4 and lay the seal as straight as possible on the hub and tap the 2X4 with a hammer spinning it as I go around the seal, until it is...
