For You Guys Looking for a Brownie

[Diesel JD]

Thx I'll check it out! Do you know what the overdrive gear on this is? .84?

I would always defer to RLDSL with respect to auxillary boxes but I was taught rear end ratio*main box ratio*brownie ratio to give final ratio. Lets assume you have an E40D with O/D at .71, further assume the Brownie is a Spicer 5831D like mine or B like RLDSL's with an O/D of .85, finally you have told us your running 4.10s so:
4.10*.71*.85=2.47 in 2OD...someone will correct me if the math is wrong but it seems valid, for example I have a T18 with no O/D and no brownie installed and (3.55*1) =3.55 or my final ratio which is correct if I had a ZF5 it would be (3.55*.77)=2.73 which also seems right, all you're doing is adding another gear ratio to give you a numerically lower or higher gear in terms of math.....

 

[Dieselcrawler]

yea, i think i will jump on it if it is still there calvin. pm me the details of it and we will go from there....

Cool thx! I used this sites Calculator, and if I did it right? If so looks like I'd be right around 2k rpm @ 75mph right? So about a 400 rpm reduction?

 

[Diesel JD]

It's a big drop. RLDSL picked up some mpgs from what he told me.

 

[RLDSL]

about 4-500 rpm drop is about right. I went from a max of 14mpg empty to 18-20 mpg if I keep it around 62 mph and now even towing heavy with my carhauler I can get 14mpg on the flats ( can't do as well with the 5er as it has a big high flat nose and the carhauler has a chisel nose, makes a huge difference on wind resistance even though they both weigh around 10k ) where it used to top out at 11 mpg loaded down. It really likes running heavy in 4 over and cruising at 62 on the flats on the interstate. I can go all the way to Dallas now and only have to downshift in one place

 

[Dieselcrawler]

Quit talking about it. Makes me want it more!!! Gota talk to Calvin bout this one......

 

[pegleg]

How serious are you?

 

[towcat]

How serious are you?

he's quite serious. but do check out the one the other guy has to offer.

 

[Dieselcrawler]

been trying to find one around here for a while, and the 3 speed one is what i wanted too. get that lower reverse gear, and a better overdrive. and considering my roommate for the rally is coming from that area...... it sorta made my choice for me. lol

 

[towcat]

what other guy?

post #15.
that's funny.
I'm on the tail end of my day and you're getting yours started

 

[Dieselcrawler]

Will look into it, nice this is the one on cl has the shifter and was rebuilt once... Duno the history of post 15. And yea I was just waking up, now u go to bed little guy. You need your rest

 

[Dieselcrawler]

Not to Hijack the post but I have a brownie and shifter id sell have no ideas on what it came out of can take pics of corse Its not an al Case though .

Located IN Plymouth CA 20 Miles East of Sacramento iv had it for 10 years never installed as i bought an 88 7.3 with a GV in it right after i got the brownie.

Was Keeping in hopes to put it in a mercedes 309D I had but lost my shop space ...

so who wants a Brownie I believe its 20 under direct and 20 over.

ill have to check on yoke size and it will be a measurement since im not versed on that stuff they are substansial but ?... i do have shifter

the how much thing $400 but its heavy and ill package and ship but that cost is on buyer

i have a friend who ships mill vechials he may be able to get it to someplace close for a minimual cost - perhaps

let me get some pics numbers as it all may be of no intrest after you see them ok?

[Dieselcrawler]

Yep, let's see it and see if u can get the modle number also
