Did you hit the plate on something to cause this?

We haven't had any problems on our WK2 yet, (even while testing in fairly difficult off-road conditions) and we haven't had any reported problems yet, but I want to pay maximum attention to any potential product failings.

Obviously this is something that should never happen, so I am very interested to hear your thoughts.

Cheers,
Bill
I haven't been off road yet and I didn't hit anything but as you know I had issues with two of the screws. It was a case of possibly over tightening and a batch of screws where the thread was not fully formed adjacent to the unthreaded portion. This should not be an issue with the 5mm plate. I think you might be using full length threaded screws now anyway. In desperation I put helicoils in all three holes but it appears one worked loose with vibration. I'm not surprised. I'll put in the nutserts which kindly provided. There are a few good ideas for home made nutsert/rivnut tools on the web.

Yes I did use locktite but with the nord-lock washers, I don't think the screw backed out. I suspect I made things worse by drilling out the holes for the helicoils. Any meat that was there was reduced to the thickness of the plate. I expect it just pulled out with vibration and body flex. Helicoils are are a godsend but pretty useless on plate.

BobT,

Ahh... I see. Bummer the helicoils didn't work. You're right, once you drill out the holes there's not much there to work with. The nutserts should provide a very durable long term solution.

If you don't mind me delaying your M6 Bolt Head Protector order a few days, I'd be happy to include a nutsert tool for you to use free of charge, if you're willing to ship it back when you're done?

Cheers,
Bill

I would advise against using Locktite, otherwise removing the sump plate to change your oil will become a bit more difficult. Once the nutserts are installed, the NordLock washers should be sufficient to guard against loosening from vibration and flex.

Red PeeKay,

I'm glad your WK2 Sump Protection Plate arrived safely. I'm pretty sure everything will fit together fine with your ECB Bar, but I look forward to hearing about your progress.

Cheers,
Bill

Oh yeah, didn't think about oil changes. Not sure I trust the wrench monkeys at jeep to be gentle with the threads on these bolts... might have to remove it before taking it in.....

Hey Benn0,

I just took mine in for the 48k service and although they only did half of it and I need to go back... Grrrrr... They had no problems with the plate and the bolts. I think this is because the stock 'Belly Pan' attaches the very same way and is just as susceptible to over-tightening.

If you look closely, Jeep has already included nutserts in these holes from the factory, they sadly just aren't very long. On a positive note, I did notice during our last test fitting that 2014 models seemed to have slightly longer nutserts in this area.

Our main concern during engineering of the plate was whether the OEM nutserts were strong enough to handle the forces that might be encountered when the middle of the plate was hit hard and wanted to pull away from the sub-frame. This was something Jeep didn't need to plan for with a plastic 'Belly Pan'. Based on our computer models, the OEM nutserts were 2x stronger than needed for everything except catastrophic failure.

Cheers,
Bill

There is no need to remove the sump plate, at least not with the CRD. There is a generous access hole to the sump plug and the oil filter is accessed from above.

If you get the chance, can you post some photos? I can't remember where the sump plug is on the CRD.
