HOW TO: Upgrade the Bulldog coupler and Andersen Hitch to 2 5/16"

Recommended Posts

A little OT, but how did you install the cross bar on the trailer side of the stone stomper?

When the cargo box was on the tongue I clamped a section of aluminum tubing to the back of it. With the box moved to the rear bumper, I had this welded up by my local shop. It works even better...

I still use Schedule 80 conduit (UV rated, heavy wall, 1” diameter) to hold up the Stone Stomper mesh. The u bolt is one from the cargo box and it goes through two existing holes, so I did not have to drill new ones in the dog house.

So, I hope my 2” ball isn’t putting me in danger.  I do think I’ll upgrade to the new hitch before we leave for our fall adventure. Mike

 

Mike,

 

I would argue that your 2" ball is absolutely not putting you in any danger.   The ball is rated for the full gross weight of the trailer.  The 7,000 lb load rating is a working rating and not a predictor of when it will snap off.

 

The ball wear is not indicative of an overload or impending failure. It's a result from the Bulldog coupler having a rough interior and not being perfectly spherical, while dealing with the severe forward load applied by the Anderson hitch.

 

I suppose, if your trailer was loaded to 7,000 lbs, and the Anderson was cranked up to an extreme force on the ball, and you ran into something at a pretty good speed, you might have a failure.  But it might have a 4-1 safety margin and nothing would fail.  I just don't know what the margin is.

 

I really don't think it is worthy of your concern.

 

I switched mine to a 2 5/16" just because I like that size, like overkill beef, and have other trailers that use that size.  Plus, I got rid of that stupid catch that tripped me every time I stepped over the tongue!

 

Next year, to the rally, bring the new 2 5/16' coupler and the ball.  We could change it right there.  But we might have to act like we knew what we were doing.  ?

John, I agree.  I have great confidence in my set up.  We do travel light and I don’t think we’re anywhere near the limits.

Hmmmm, you’ve got got me thinking about this..... I’ll bet there would be no shortage of others who could gather round and act like they knew what was going on too!

For those of you that installed the 2 - 5/16 bulldog, did you have to get a different model hitch or tong lock for securing your trailer?

If yours has a ball that goes up inside the coupler, of course you do, it would fall out otherwise. I have The Collar and it works on all sizes of Bulldogs, since it secures the back of the sliding sleeve.

This is a great device when combined with a GOOD quality padlock (not a stupid $10 disc lock as shown in those pictures). Highly recommended. It has a high theft deterrent value too.

I wish OTT used inserts for 5/8″ vice 1/2″ bolts. I was reading some older threads about 1/2″ grade 8 bolts on the telescoping tongues shearing off. Scary stuff.

Jitters,

 

I have never heard of this. Where can I read about it? The main cross bolt on the telescoping tongue is very large and cannot shear off because the tongue telescopes. It only sees stress from braking and acceleration and the bolt seems stronger than the material around it. The smaller 7/16″ cross bolts in the bulldog hitch are under a shear load. Mine were beginning to elongate the holes in the coupler because the nuts had bottomed out on the threads before pinching the coupler tight to the tongue. The fix, while installing the 2 5/16″ coupler, was to add a couple of grade 8 washers on the bolts

 

I have never heard of any of these bolts shearing off.

 

 

Hi Raspy!  Granted this was a while ago....

Greg,

 

Interesting.  I have never seen that discussion.

 

The telescoping tongue went out of production before hull 200.  This lead to some grumbling by those that wanted it, and some who were surprised on delivery day to find it missing.  Mine is Hull 92 and has it, but the cross bolt is a 3/4" grade eight bolt with nylock nut and large washers.  I've had it out and it looks fine.

 

The trailer being discussed in the link was hull#32 (don't know if it was an Elite, or Elite ll).  And that was nearly 9 1/2 years ago.

 

Oliver continues to make small incremental changes over time and this must have been one of them.  Yikes!

 

The issue is certainly not a problem now, with the non-telescoping tongue that looks incredibly strong.

Understood.  Being retired Navy and working for NAVFAC for 15 years I am always thinking about safety.  When everything is connected by those two bolts on the coupler it seems a safer bet would have been 5/8 or 3/4 in bolts rather than 1/2 inch.   I'm sure the 1/2 is fine...but.... :)
