Video Transcript for Review of Bulldog Bulldog Jack 3/8 Plunger Pin - BD500103

Michael: Hi, there. I'm Michael with etrailer.com. Today, we're going to take a quick look at this replacement three-eighths inch diameter plunger pin assembly for your Bulldog Jacks. This is going to replace a three-eighths inch diameter plunger pin that will allow you to hold your extendable leg in place on your jack, and then pull it out so that you can retract or extend that leg. Again, this is going to include the spring, the cotter pin and washer for you to get this all installed. So if your original plunger pin has become damaged or lost, whatever the case may be, this is going to be a great option to replace it for those Bulldog Jacks.

Now keep in mind, this is just for the Bulldog Jacks. It's not going to work with the Fulton Jacks. So if you do have a Bulldog Jack, you're needing this plunger pin, this is a direct replacement from Bulldog Accessories.So it should be a direct replacement. You're not going to have to worry about any modifications or anything like that. Let me give you a few measurements, just to give you a little bit extra peace of mind that this is going to work for your jack.

So this is right at, I'm going to call it four and three-sixteenths of an inch long. From the center of our hole to the end, it's right about seven-eighths of an inch, just shy of one inch. The straight portion of the pin here is about two. And depending on where you want to call that straight, I'm going to call it about two and one-eighth of an inch. And of course, it is a three-eighths of an inch diameter.

So again, if you need a plunger pin for your Bulldog Jack, this is going to be the exact replacement that Bulldog Accessories offers. So that's going to complete our look for today. Again, I'm Michael with etrailer.com. Thanks for watching.

Earlier this year my neighbor decided to borrow my trailer. The jack wheel was frozen to the ground, so he decided to try and tow the trailer out of the ice, breaking the plunger pin clean off. This replacement was exactly what was needed to fix the problem.
Better than replacing the whole assembly.




by:

Product was good and etrailer was easy to deal with and prompt. Excellent communication & follow up.

Product still works great after a year in service

Jack plunger pin was a perfect fit. Shipping was quick. a satisfied customer again thanks


Comments
Jack is still going strong, used almost daily. great parts. Thanks again
Andy H - 02/03/2015


by:

The only problem I had, and it may be because of the different brand of jack, was that the included spring bound up when trying to pull the pin back, so I ended up using the original spring. Once again this may be the fault of having a different brand jack than the pin I ordered. Great service, and fast shipping.




by:

I needed parts to mount an old jack stand I had salvaged. I found all the parts I needed at etrailer.com. They have good service and parts at a good price.




by:

I don't know what jack I have on the used trailer I just got. The pictures on the website were excellent, and I gambled on this part. Perfect fit, fast shipping. Couldn't be more happy shopping online here.




by:

These guys are GREAT!!! Part was shipped to ALASKA at at standard shipping rate THANK YOU for that.
Part installed and works just fine I recommend etrailer.com for your first choice for all your trailer needs. EXCELLENT can't say it enough




by:

Good product, good price, didn't solve our problem. Order was shipped timely and showed up when it was expected. I woiuld do business with eTrailer.com again and would recommend it to anyone who needs trailer parts.




by:

The plunger pin is exactly as described and matches up to the one I need to replace. Excellent quality, not cheap after-market steel.
etrailer shipped the part very fast. I can't give an excellent rating since I don't give anyone a perfect score.




by:

Happy to get this from etrailer.com, 3/8” plunger pin assembly works great and the shipping charge was decent, all in all, everything with this purchase was A-OK.




by:

Wonderful service and super fast shipping. The only problem is that the pin is half an inch too short.


Comments
If you could tell us the manufacturer/brand name and model number of your existing jack, wed be happy to try to find the correct replacement plunger pin for you.
-- Etrailer Expert Mike L - 05/22/2018


by:

Local trailer "experts" at Adams told me to buy a new unit. For under ten dollars the new pin works.
However, it is shorter than the original, it needs some care when using.

Buying local doesn't seem to work for me anymore.




by:

Product as described -was very hard to find at a reasonable price- adequately
package- what's not to like doing business with a company like this!


Comments
works great!!!
Jeb B - 04/04/2018


by:

Received what I ordered in a timely man ner.




by:

I received the package and appreciate the service. My son will install it on the trailer Jack. When I asked to have the company that made the Jack, they told me I had to get a new Jack.




by:

from the cotter pin to to the device was too short, it pulls out of the housing requiring a third hand to reset it.




by:

The plunger pin fit perfectly and the shipping was very fast. they are great people to do business with.




by:

Back again...Great site for obscure parts. Quick on shipping too!

Thanks to all at etrailer.com!




by:

Product as described. Fast shipping. Liked the email follow ups during the shipping process. Would definitely use etrailer again. Thanks

  • Replacement 3/8 Inch Diameter Pull Pin for Swivel Trailer Jack
    Yes, we have a selection of 3/8" diameter pull pins for swivel trailer jacks. However, I would need to know the brand and model of jack you have in order to confirm fitment. For example, the Replacement Plunger Pin Assembly part # BD500103 is a replacement 3/8" diameter pull pin for Bulldog trailer jacks. Once you can let me know which jack you have, I would be glad to see if we have options for you.

  • Replacement Jack Plunger Pin Assembly for 2007 Fleetwood Sun Valley
    Many of these jack parts are pretty specific to the brand of jack they are used on, and are usually not interchangeable. Without knowing the manufacturer or model number of the jack on your 2007 Fleetwood Sun Valley, I would not be able to say if the # BD500103 you mentioned is an acceptable replacement. I can provide the dimensions of the replacement plunger pin, and hopefully that will help you decide if the replacement will work for you. If you would care to respond with the manufacturer...

  • Trailer Jack to Replace Shelby 5856A Pull-Pin Type Swivel Jack
    We do offer a replacement pull pin kit for some Shelby square tube drop-leg jacks but according to my contact there a kit for their 5856A swivel jack is not available. Part 2248-50 is no longer active on their site. If you care to review replacement jacks you can click on the linked page to see all pull-pin swivel jacks from makers like Atwood, Fulton, Shelby and others.

  • Replacement Plunger Pin Recommendation for Bulldog Landing Gear
    It sounds like you are looking for a replacement plunger pin kit for the landing gear on your trailer so that the inner tube of the landing gear can easily be raised or lowered. If the landing gear you have happens to be by the brand Bulldog you would want the part # BD500103. Here are some specs for you to compare to what you have on your trailer: Pin diameter: 3/8" Length of pin: 4-1/4" Hole center to short end of pin: 7/8" Straight portion of pin: 2-3/8"

  • Trailer Jack Replacement Plunger Pin Recommendation for 2001 Coleman Pop up Camper Trailer Jack
    Yes, the Bulldog 3/8 inch Diameter Plunger Pin Assembly part # BD500103, will work for you. From the end of the pin to the start of the curve at the base of the handle end the pin measures 3 inches. The overall length of the pin is 5-1/8 inches.

  • Replacement 3/8" Plunger Pin Needed for Atwood Swivel Jack on Boat Trailer
    We do have some 3/8" Diameter Plunger Pin options for you to use with your Atwood swivel jack, but none of them are Atwood branded. The Bulldog # BD500103 that you referenced has the 3/8" diameter and measures 4-1/4" long. This is only 1/8" shorter that your current pin so it will work great. If you wanted at least the same length then we have the Dutton-Lainson # DL22449 which also has a 3/8" diameter but it measures 4-11/16" long.

  • Replacement Swivel Handle Kit Part DL22449 Measurements
    I went to our warehouse to get the swivel handle kit # DL22449 to provide you a few measurements to determine if this is the right part for your swivel jack. From the center of the cotter pin hole to the end of the handle is 1-1/2 inches. This measurement may be a tad to small from what you referenced of 1-7/8. The diameter of the swivel handle is 3/8 of an inch. The length of the handle from the end (end closest to the pin hole) up to the nearly 90 degree angle is slightly over 2-1/2...

  • Replacement Plunger Pin Recommendation for Fulton Swivel Marine Jack
    I spoke with my contact at Fulton and he stated that with the 800 pound capacity swivel jacks the most likely pin is the 1/2 inch diameter pin # F0933307S00. If you measure the hole diameter for the pin, that will tell you if this will fit. The 3/8 inch plunger pin, # BD500103, that you referenced will not fit Fulton jacks.

  • Replacement Trailer Jack Recommendation for Shelby # 5856A
    We have the Fulton trailer jack part # FTJ120W0301 which we know fits the same trailer mount as the Shelby 5856A that you have so this would be our best option for a solid jack with a very easy install. This jack has a 1,200 lb capacity, a wheel caster, and is a sidewind which I think is easiest style to crank. I attached an install video for this for you to check out as well.

  • Replacement 3/8 Diameter Plunger Pin Assembly
    The plunger pins are usually specific to the brand of jack and usually are not interchangeable. Unfortunately, without knowing the manufacturer and model number of your existing jack, I cannot say with certainty that the pin will work for you. I have provided a photo showing the dimensions of the plunger pin you referred to, as well as two others we offer. You could compare those dimensions to the pin of your existing jack to see if any of them would be a correct replacement.

    The F0933322S00 that you referenced has been discontinued by Fulton back in 2013 so we no longer carry it on our site. The only 3/8 inch plunger pin kit we offer now is the # BD500103.

  • Need to Replace 3/8 Inch Plunger Pin on Fulton Jack
    I spoke with my contact at Fulton and as long as you have a Fulton branded jack, it is acceptable to drill it out to 1/2 inch in order to use the Replacement 1/2" Plunger Pin Kit , # F0933307S00. As you stated in your question, a replacement 3/8 inch plunger pin is no longer available for the Fulton jacks so drilling would be your best option.

  • Replacement Trailer Jack to Fit the Mount for a Shelby 5658A Swivel Jack
    How did your jack attach to its mounting bracket? Is that the single bolt that you mentioned? If so then the only option we have that could work is Fulton jack # F1411300301 which normally uses mounting bracket # P9012-00. And the replacement hardware for that bracket is # F0933325S00. The bolt is a 1/2 inch but it uses that included bushing in the center hole of the mounting bracket.
