Does your truck still have the CAT 3116? Any pros of the M920 over the M1070?
The XM920 MET (medium equipment transporter) is powered by a 600 hp Cummins ISX engine and an 18 speed Fuller Road Ranger transmission. It runs 79mph and cruises nicely at 65-70mph all day long.

The M1070 HET (heavy equipment transporter) is powered by a 500 hp 8V92 Deroit DDEC III / IV engine and an Allison HT750 five speed automatic transmission. It runs 47mph all day long....lol

The FEMTT (fast expanded mobility tactical truck) is powered by a 425hp Big Cam III Cummins and an Allison HD4070 seven speed automatic transmission. It runs over 80mph, also cruises nicely at 65-70mph and (as I recently found out) it has trouble following the HET and not have the rpm fall out of the power band on the lower end....lol

None of them ever had a CAT 3116 engine....are you maybe thinking the CAT 7155 16 speed transmission?

I think I read at the beginning of this thread that Soni was looking for a way to get more low end gearing on the FEMTT. I ended up with an extra Oshkosh two speed 55000 transfer case if Soni or anyone else needs one. New in 2008 still in the military crate.

Rear quarter fenders and self recovery winch fairleads

I have been trying to find the roller fairleads that go on the front and back of the HEMTT ever since I got the side mounted, 20,000 pound self recovery winch!
Well a couple of weeks ago, I got an early Christmas present! I found a couple of them on Ebay brand new!
So after a few slight modifications (turns out Oshkosh was not planning on them being used on FEMTTs :( )I got them installed on the FEMTT.

The rear one is usable as we speak and the front one is awaiting the installation of a recently purchased cable tentioner to make it operational.

Since I needed to finish the rear winch mount and that required to have the right quarter fender integrated in to it, I decided to bite the sour apple and fabricate the left rear quarter fender as well....

Here are some pics....

Hanging a sign with the FEMTT

Here is a somewhat different view of the FEMTT....."riding the hook" to install a sign for our favorite breakfast "watering hole"....:-D

Btw...the gentleman standing by the rear of the FEMTT is famous racecar driver Al Unser senior....he stopped to see what we were doing....

I certainly hope you let him drive it!
As you know, I am an enthusiastic ambassador for the MV hobby. One question begs to be answered here....

Will we be welcoming Mr. Unser into our hobby anytime soon?

Why not, Arnold has a tank!






Carry on.

Hey Sonny, as always, factory looking fab n install!, but I am wondering why you have a matching hole in the left 1/4 fender that doesn't have the self recovery winch infront of it, since they were both fab'd from scratch?
Maybe you want symmetrical road poop on the frame!!!

Will you be putting a split rubber flap over the self recovery cable on the right fender?

Good observation Zebedee and thanks for calling me out on that! lol
This hole is kind of a screw-up....haha! After fabricating the winch side first and building kind of a hawse fairlead in to the inboard side of the fender. it looked really stupid with the narrow one on the left. So we extended it inboard as well. It may have a use with some of the modules, to route the hydraulic hoses to the quick connects in a more straight way, but for now its just getting a bolted on cover.

It's funny you mentioned the rubber flap for the winch....I thought about that as well, butt I was afraid that the cable moves around too much (up and down and side to side) for a simple slot to work.
Also, on both sides the openings are inboard of the tire tread so not much "poop" gets thrown there anyway....lol
