Why bin it, looks like a safety shear bolt to me to prevent major breakage from overload, good design to have a shear bolt

looks like it has had more weight on it then it should have

Agree with Blaze and Dogbox _ it appears the "Stud" has been bent by lifting the weight of the van - I would relace the stud with a machined hardened pin.

Shoddy work.
Should be a hardened metal pin, not a full threaded bolt. The engineering is crap. The diameter of the pin should be a snug fit through the threaded rod and the outer sleeve should also be the same diameter. The only thread should be at one end only, with a nylock or castellated nut. The whole pin should be as Possum Three said, a hardened pin. No necessity to have a shear pin for that application.

Would be easy to fix !!

A shear pin is there to create a weak link to fail to protect other components, they are designed to fail. Saves throwing the unit in the bin, odds are it probably had a spare in the box as new

Hi Guys,
there is no weight in the bolt at all, the weight is on the threaded shaft and the top collar .
the bolt just holds the threaded shaft into the top collar when the leg is suspended
when you raise the leg to far it puts stress on the bolt
there should be some sort of electrical stop when the leg is raised to stop the leg coming up to high
and stressing the bolt
if I was going the keep the electrical jockey wheel I would replace the bolt with high tensile bolt
and mark the leg so it wouldn't come all the way up
If any one else has these jockey wheels I would suggest changing the bolt
to prevent the bolt stress and the potential of the leg dropping to the road when driving
causing a lot of damage
any way I think I will buy the hydraulic leg lol
cheers Ken

Hi everybody,
Just thought I would share this with you
I fitted an electric jockey wheel to our van, it has been used about a dozen times
we just got back from a trip and just pulled up in front of our house
when the leg of the jockey wheel just dropped to the road
very lucky it didn't happen when we were traveling along at 95Km would have done some damage
anyway it has been taken of and now in the bin
In the photos you can see the mild steel 4mm bolt sheared off
cheers
