MAX Burner Posted March 16 Share Posted March 16 It's interesting that this condition made it through all the Quality Control checks performed during the build process. OTT may need to validate employee training associated with the BD install process, review their QC checklists, and at least brief employees regarding @rideadeuce's bullet-dodging experience. 100% concur w/@Rivernerd's assessment - there's certainly a reimbursement on the radar screen for repair costs, IMO. 1 Art, Diane, Magnus & Oscar (double-Aaarrf!) 2022 TUNDRA 2017 LE II; Hull #226 "Casablanca" HAM call-sign: W0ABX Link to comment Share on other sites More sharing options...

Less of a PITA and NO more mallet! I just started doing it this way too. I believe I get about 5 threads each side. 1 Chris & John in Prescott, AZ | 2016 EII #113 | '01 Ram 2500 Cummins!

Every rig likely doesn't have the exact same number of chain links. 7 to 8 threads, for us, applies just enough of a "squeeze" on the red bushing to keep the nuts from backing-off while towing. We definitely check the nut tightness at our first stop - I've found them to loosen sometimes.

skalywag Posted March 16 Share Posted March 16 I just visually inspected my 2" Bulldog Hitch and it appears solid. Even though our Ollie is a LE1, It has a 7000 lbs capacity rated coupler and It has the gusset which seems to be adequately welded (visually). I am thankful for this thread to make me do this inspection and I'll be keeping an eye on it and how this issue gets resolved. 3 Legacy Elite I #240 Link to comment Share on other sites More sharing options...

John Dorrer Posted March 16 Share Posted March 16 (edited) I just checked our 2022 LE2, 2" Bulldog. Ours is rated 7,000. Outside of surface rust, ours looks fine. I intend on sanding rusted areas and applying Rustoleum in two (2) coats when we get home. I need to check the underside for the guset.

Steph and Dud B Posted March 16 Share Posted March 16 2 hours ago, rideadeuce said: looks like to me the wrong coupler was installed from the factory. 5k instead of the 7k coupler You should send this to Oliver immediately, as well as filing an NHTSA report. There could be other Olivers out there with the wrong couplers. A recall notice should be issued for all Oliver E2 owners to check their couplers and OTT should replace any others that might be found. The NHTSA is important because OTT may not have contact information for some older trailers that have been resold. 4 Stephanie and Dudley from CT. 2022 LE2, Hull #1150: Eggcelsior.

Like in the above pics where there is rust in the center of the fracture and clean bright metal at the top and bottom. Maybe someone else can explain how this can happen Dave Phelps post got me to thinking. After taking a “Deeper Dive” into this rabbit hole, I have to admit that my salt water/ocean air hypothesis may be all wet. Full disclosure: I am not a metallurgist but with my slide rule, I can still do some structural analysis. But in this case, I think the below interpretation may hold some water. So, this certainly is NOT an official analysis of the cause of the failure. Just the musings of a member of the OTT Rabbit Hole Investigator Team. 😊 As stated in the initial report, the top metal of the Bull Dog (BD) was still somewhat intact after failure. Had this metal also failed, we would be having a discussion about safety chains (Again). But fortunately, that was not the case and there were no injuries. Thank the Lord. Also as reported, and from the below inverted picture, we can see older damaged metal (Rusted), and at time of collapse damaged metal (Shiny white metal). This photo shows us that both sides were well compromised long before the failure event. CURB SIDE OF BD STREET SIDE OF BD But, as evident from the photo from the street side looking at the side of the BD, the street side was predominantly ripped apart during the failure event. Whereas the curb side was damaged long enough in the past to be fully rusted. TV END OF BD OLLIE END OF BD So paraphrasing Dave P's. musing: With or without the horizontal gusset how could this disparity in damage to the side metals happen? But first, let’s “Dig” into what the purpose of "The Gussett" is and likely why BD added it to their 2" couplers. Here is what they look like: The gusset is located near the juncture of the BD round pipe and U-shaped metal attached to Ollie. I believe that the purpose of a horizontal structural member (I.E. Gusset) is to reinforce the round to “U” shaped metals junction from being damaged by side horizontal loads. From the posts, it appears that older BD 2" couplings did not have this reinforcing structural member. I suspect after some lateral failures the design was beefed up to resist lateral loads by adding this gusset. When a box, round or square tube is lateral stressed by an impact load, the impacted side will go into compression and the opposite side will be stressed by tension. So historically for all BD couplers, with or without the gusset, what is the most likely event that would cause side wall cracks with such a disparity as seen above? I think a side impact load. And how would our OE2’s likely incur such an event? By a backing jackknife event where the Oliver aluminum box strikes the bumper thereby bending the BD laterally. So, as a member of the TV dented bumper owners group, I’ll be under my BullDog with a flashlight FOR SURE. For extra points, which bumper would also been damaged? Your thoughts?

Moderators SeaDawg Posted March 17 Moderators Share Posted March 17 Frankly, though i hate to admit it, after 16 seasons, we've put a few dimples in from jacknifing. Not the end of the world. Usually. I've looked at the photos, and I'd say rare manufacturer's defect, and great catch, lucky you. Bulldog is best of the best. Imo. We inspect ours each season, but no issues 16 years in. I'm super glad no issues for you,,and your family. That's a big relief.

mountainoliver Posted March 17 Share Posted March 17 Just as a suggestion, Oliver should use the 7,000 pound version for all of the trailers. There’d be no chance of mixing up the couplers and very little to no cost difference in the grand scheme of things.

The 2" Bulldog Coupler is rated at 7K. The 2 5/16" BD coupler is rated 12,500. The OTT OE2 Springs for years were rated at 7K. The Broke Spring post is suggesting increasing the springs to 8K.

rideadeuce Posted March 17 Author Share Posted March 17 (edited) 9 hours ago, Geronimo John said: The 2" Bulldog Coupler is rated at 7K. For me and everyone who owns an OTT E2, the issue is the 2 in BD coupler comes in 5k and 7k versions. They look identical except for a small gusset at the neck welded internally. During the build of Hull 308, a 5k coupler was used on my E2 by mistake and it failed while on vacation with my family. Again, they look identical but the rating is shown on top of the ball end of the coupler. Everyone with an E2 needs to check theirs to make sure it is a 7k version and not a 5K.

Best, Mike So a 5000# BD hitch was installed where a 7000# BD hitch should have been installed. Sounds like the cause of failure/issue has been identified. I have not heard or read where any 7000# BD hitch has failed on an Oliver LEll. That said, all owners would be wise to periodically inspect their hitches for proper the weight rating and serviceability especially if you purchased an older preowned Oliver. Other than this I will continue towing with 💯 complete confidence in my present 7000# rated BD hitch. I feel sure Oliver will address this issue with any owners IF they have a 5000# BD on their LEll and make it right. Again, glad you and your family are safe.

mountainoliver Posted March 17 Share Posted March 17 Now that we know that the coupler was basically misused (not user error) and repeatedly overloaded by almost 2000 pounds, I’m sure that the Bulldog folks will not provide any sort of warranty replacement. They may however be interested in knowing that their product held up for so long under adverse conditions. This is purely an Oliver oops moment in which everyone is extremely fortunate that nobody was hurt.
