hi all

getting ready to install a PMF transfer case reindex plate and PMF transfer case cross member.

kit is going into a 2019 f-450 4WD 6.7

the system turns your transfer case so that the output shaft for FWD winds up with a reduced drive line angle.

the system comes with a plate that presumably goes between the tranny and transfer case. bolt holes for the original position and new holes with bolts for the new position on the tcase side.

it should be pretty straight forward unless there are some standard tcase removal items that need to be considered.

looking at everything...it looks like the best approach is

1. remove the RWD drive shaft from the Tcase .
2. remove bolts that hold the tcase to the xmsn
3. remove the tcase cross member (prepare to support tcase some how)
4. slide tcase out of its position in xmsn
5. either bolt the index plate to the tcase or the xmsn (not sure since the index plate has no instructions)
6. turn the tcase into its new position (supported with straps , etc)
7. bolt the tcase to the xmsn
8. install new crosmember
9 reattach RWD drive shaft.

so this is my guess on the approach.

I called PMF and they said they do not have instructions for the system but if I get stuck, I can call them back.

I guess its one of those things that if you cant figure it out...you should be doing it.

before I start, I need to verify the sent me the correct year parts ...they have a 2011thru 2016 kit and a 2017 to 2020 kit and I need the later. dont want to disasemble everything and find that I have the wrong kit.

any remove and reinstall gotch info would be helpful.

thanks



looking for any info on the transfer case removal.

 

So, I gotta ask. How thick is the adapter? Reason is there isn't much spline contact from rear of transmission into transfer to begin with and unless this kit came with a output shaft extension you are going to lose spline contact by at least the thickness of the adapter. You are also going to have a shorter slip distance from rear driveshaft to transfer and more from front driveshaft to front differential. To me you are going to weaken the connection between trans and transfer. Are you sure you want to do that? Did the company address any of these issues when they built the adapter kit?

 

Subscribing, trying to understand why this is needed.

Did you have a problem with binding or excessive shudder or u-joint issues?

 

the way the adapter plate is setup , the net thickness add is about 1/8 to 3/16’s of an inch.

the plate has a collar that inserts where either the tcase or Xmsn does on one side and on the other side of the plate it’s recessed to accept a mating surface.

 

I have a very steep angle on my front shaft cussed by

5” lift and the addition of a pinion arm drop plate .

there is about about 1/2 of an inch of clearance between the output of the fwd tcase and the tcase output housing.

in fwd, on very bumpy roads, I get ringing from the output shaft hitting the tcase housing.

Fritz I think you're part of the team now.










Couldn't decide so they both made it...

 

Definitely

i drove it 4 miles with no rear drive shaft to pick up the new shaft.

didn’t like what I was hearing or feeling at the front drive train.

 

Good luck with the project... Love the fact that you're doing this your way.. Built and not bought.

I have a lot of respect for that...

 

Once the indexing ring is installed please drive it without the rear driveshaft again and let us know if you notice an improvement.

 

a project for sure. one nice truck once done.

 

Good day

in getting ready to install a transfer case reclock kit. Basically is a plate and new frame mount that lets you pick a new oreintation so that your forward output shaft is level (needed moreso on lifted trucks).

before I begin..I’m seeking info on any “watch out for” and “gotchas” that I may run into as nothing on these trucks ever go as planned.


thanks for any input.

 

its been 4 years since I started this thread and I am now getting around to having to get this done.

quickly going down my someday list .

I did find some instructions for a different brand so at least some sense of how things should go are in hand.

hopefully can get this done before it gets cold.

 

FWIW...check with a local driveshaft repair shop about them removing the factory cv joint (at the t-case) from your front driveshaft and have them weld on a double cardan u-joint. These are a must on most lifted trucks and have been around for decades.

I already have the reclock kit

but thanks
