Trailer Mounted MEPs

Light in the Dark · Jan 12, 2019

Does anyone know the bolt size for the trailer mounted MEP units? I had dismounted one previously... and can't seem to find where I squirreled them away to. I definitely see them called out in the TM 9-6115-659-13&P, but not unique identifier info.

Thanks for your help.

I have some I can send you, do you need 4? I am away from the shop today so I can't get to them right now to send you the size.

I believe the originals are 1/2" x 2", 2 flat washers, and a lock nut. The 1-1/2" bolts in image were for an ill fated camper project.

Which Model? There are some differences.

I have (2) LTT-TQG trailers coming in this week, and need to put (1) 803A on one for a pickup next weekend (the other will be used down the line). I appreciate the offer Bob. If you just want to measure them, that will help just as much (Can have some arrive next business day by MSC/Fastenal, etc). I assume they are Grade 5 minimum.

This is for the nut. Its a grade 5

If you want the tech data for the washers, got that too.

Please take a picture of the Data plates on the trailers. I want to look at something.

I will, when they come in. Tentative drop date is this coming Friday. Thanks for the above info Guy. Time to go peek through the garage...

Zed254 · Jan 12, 2019

Here are data plates on the Silver Eagle LTT generator trailer I own.....

Well I lucked out... I actually hid the set in the tool box of my own PU797C! Thanks everyone.
