Mounting Bolt Pattern of the Bulldog A-Frame Jack and is Hardware Included- The bolt holes on the Bulldog Round, A-Frame Jack, item # BD1700100317, triangle mounting flange are 3 inches from center of one hole to the center of the next hole. They are equally spaced apart and they are elongated for easier installation.
A-Frame jacks are all the same size and have the same bolt-pattern. The manufacturers did this so they could simplify the manufacturing process for both bolt-on and weld-on A-frame jacks.
The jack can be bolted on, hardware not included, or it can be

- Why Would a Bulldog Powered-Drive Kit Operate Slowly on a 4000 lb Trailer
- I spoke with my contact at Bulldog and he said there are a couple things that could be the reason for why the motor is working slower than you expected.
First thing he said was that you need to make sure the motor is wired up with between 10-12 gauge wire. You also want to make sure you have a good ground.
He said you also need to consider the condition of the jack. If it is older and it was difficult to operate manually then it will also be difficult for this motor to raise and lower the

- Jack Replacement Recommendation for a 2007 Vikin Epic Pop-Up Camper
- As long as the trailer for your 2007 Viking Epic pop-up camper is built on an A-frame this Bulldog Heavy-Duty jack # BD165412 could work for you. I did a little research and it looks like most of pop-ups like yours use A-frame jacks. You will want to consider the height of this jack. At 23-1/3 inches from the mounting bracket to the top of the jack you will want to make sure there is nothing that would interfere with that.

- Power Drive Jack Recommendation for a 1987 4 Star 6 Horse Slant 13,500 lb GVWR Trailer
- I would recommend going with the Bulldog Square Jack, # BD182815, or the Bulldog Square Jack, # BD182805. These jacks will both work with the Bulldog Powered-Drive Kit, # BD1824200100, that you referenced and feature 10,000 lbs of lift capacity. These are the best heavy duty jacks we carry at this time, and we do not have a hydraulic trailer jack option available.
The main difference between these two jacks is that one has a side facing plunger pin at the base and the other has a forward fac

- Bulldog Collar-Lok Coupler Recommendation for a Tandem Axle Flat Bed Trailer
- As long as the 5,000 lb capacity of the Bulldog Collar-Lok Coupler # BD028384 or the Bulldog Collar-Lok Coupler # BD028288 is adequate for the weight that your flat bed trailer will see then either will work well for you.
The difference between the two is in the latching mechanism. The # BD028288 has a low profile latching system that would work great if you needed additional clearance near the draw bar of your vehicle. If you did not have any clearances issues in that area you could use the

- Installation of Bulldog Powered-Drive Kit for Single-Speed Jacks # BD1824200100 on a Trailer
- The Bulldog Powered-Drive Kit for Single-Speed Jacks, part # BD1824200100, should be wired to a trailer battery. The four wires in the wiring harness are white, black, red, and green. The red and black wire will go to the red and black wire on the motor. The green wire will go to the positive terminal of the trailer battery and the white wire will go to the negative terminal of the trailer battery.
The problem with connecting it to your trailer wiring is that the smaller gauge of the wire in

- Recommendation for a Powered A-Frame Trailer Jack
- For a Bulldog A-frame trailer jack like # BD155032, or a similar jack, there is not an electric conversion available. For a powered A-frame jack, the highest capacity we carry is a 4,000 pound model. If you want to stick with Bulldog, use # BD500185.
Since it will be at the front of the trailer, all of the trailer weight will not be on it, just the tongue weight of the trailer. Provided the tongue weight of your trailer does not exceed 4,000 pounds, this jack will work. I have incldued a link

- Wedge Style Latches Vs. Trigger Latches on A-Frame Couplers
- The main difference between the wedge style latches and the trigger latches is in the capacity of the coupler. The lighter capacity couplers will use a trigger latch, whereas the higher capacity couplers will use wedge latches.
For example, the Bulldog Heavy-Duty Cast Head Coupler w/ Wedge Latch # BD44125W0317 that you referenced uses a wedge latch and has a capacity of 12,500 lbs. An A-Frame Coupler # CA5100B uses a trigger latch and has a capacity of 5,000 lbs.
Either style will work gre

- Hitch on 23 Foot Motor Home Drags When Pulling Wells Cargo Trailer
- Since there is such a big gap from the rear axle to the end of the motor home there will be an increased chance the hitch will drag.
You could use the Bulldog Cast Head Coupler, part # BDA2005C0317, but you would need to have it welded onto the A-frame of your Wells Cargo Trailer by a trailer professional or certified welder. This would then allow you to use a ball mount with less of a drop. As you may know, you will still want to make sure the trailer is being pulled as level as possible wit

- Jack Caster for Enclosed Cargo Trailer
- The Bulldog Removable Caster, part # BD500245 will work just fine for you if your existing jack has a 2 inch diameter inner pipe. The caster itself only has an 800 lb capacity, so using it will limit the capacity of your jack to 800 lbs.
Part # BDCP555 would also fit a 2 inch diameter pipe, and offers a 1500 lb capacity.

- Which Bulldog Powered Drive Kit Works with 2 Speed Bulldog Landing Gear Trailer Jacks
- A 2 speed jack will have a second gear set attached to the jack. It would either be operated by taking the handle off of the first speed and moving it to a separate spot on the jack for the second speed or, more commonly, the crank handle will be pushed in or pulled out to engage the second gear set. Take a look at the Bulldog 2-Speed Jack, # BD183816, as an example.
It does matter between single and 2 speed when you are looking to add a powered drive kit. The powered drive, # BD1824200100, t

This is the smallest tube diameter jack without a mount that is available. There use to be a 2 inch diameter jack available, but it is now obsolete.

- Can I Bolt On a Weld On Bulldog Collar-Lok Coupler
- It may be possible to install a Bulldog Collar-Lok Coupler w/ High-Profile Latch # BD028387 on your trailer by drilling holes in it and using grade 5 or higher bolts to secure it to your trailer, but since it has never been tested I can not safely recommend you do it.

- Trailer Jack Recommendation for a Trailer with a 2 x 1-1/2 Inch Frame
- I went out to the warehouse to measure a Bulldog Rack-and-Gear Jack, # BD162300. The smallest trailer frame it could mount to is 1-3/4 inches square so it will not fit on a 2 x 1-1/2 inch frame.
I recommend a Bulldog Rack-and-Gear Jack, # BD161300. This jack has an L-shaped mount that will need to be welded to the bottom of the trailer frame. The trailer frame size you have will not matter for this jack. This is the best option I could find for you. It does not swing up but it does retract t
