Over drive and PTO fitment

[davem201m38]

Hello all,
well this winter it looks like I'm finally getting round to fitting the winch and PTO and to make European trips and our mororway trips safer an overdrive.

Now they'll both match with a lid'l help from an A-DAP-TER kit (couldn't help the Jonny Cash)

The overdrive is one of Herm's and the PTO is a Ramsey (not THE Ramsey)

Oh yeah, for safety I'm also fitting a duel circuit master cylinder and a remote top up reservoir for the master cylinder.

So, any issues you guys can think of that I should be awear of?
Thanks,
Dave.

Hi Dave,
I have an overdrive fitted to my M38 and love it. I also have the PTO Adaptor and the correct pto for the M38. I have not installed the pto because with the overdrive, adaptor and pto all bolted together, the shifter
for the OD would require a hole cut in the tub right where the leg of the drivers seat mounts. This would require repositing the seat mount or using a seat frame from a CJ3A.
Hope this helps,
PS, I have "THE Ramsey PTO"

Thanks Larry,
I'll try and modify the linkage so the lever come up where it's shown in the diagrams without the added PTO.
Yes Wes, here we have a good old English word that isn't actually an insult for people with tag libe like, PS. I have "THE Ramsey PTO"
All the best,
Dave.

I guess I should have proof read my message. The lever for the OD comes out in the normal position, it is the shifter for the PTO that is the issue with the seat leg. What is that word, Quote "we have a good old English word that isn't actually an insult for people with tag libe like, PS. I have "THE Ramsey PTO" Just poking a little fun.

Dave what PTO are you using? I have installation instructions for mounting the CJ version if you would like them.

Hi again Larry,
I don't have all the parts together yet so could you just explain something I don't get, not having the parts I'm working from web site diagrams and drawings which is not the best.

I can understand the PTO lever being repositioned as the PTO is pushed further to the rear, but I can't figure why the OD lever would be repositioned if it had the adapter and the PTO bolted to the back of the OD unit.

I've never done this (or seen one in real life) so please explain s-l-o-w-l-y for this poor Limey.
Thanks,
Dave.

Hi Larry, its a PT-1J I'm using.

I'm planning on cutting a couple of inches out of the middle of the chain box to shorten it to the same length as the 'real ramsey' That way I can keep the exhaust system unmodified.
Mind you I haven't seen it or took it apart yet so I don't know just how feasable that plan is.

I'm also trying to figure out how to make a linkage to position the PTO drive in the right hole

Wes, if you pick this up, thanks for posting the winch dimensions post, can't think why nobody thought to do it before given the hundreds of posts asking for dimensions. Good idea.

Although Art makes a good point I can see why Dave would rather shorten the Ramsey box with parallel sides then the tapered Koenig. I would think the Koenig would fit better since it doesn't have the long rearward setback of the Ramsey.

Well I've now been out in the light to pull the old rear drive output PTO and do a tooth count for the OD.

Now I properly understand about the PTO lever; its not the lever coming through the floor that is the problem, it is the PTO turret coming up through the floor, for which I can't figure a way round other than repositioning the seat leg.

And suddenly there doesn't seem very much room between the centre line of where I think the PTO will be and the floor. Has anybody ever fitted a OD and this PTO on an M38?

Scraching my head in -5degrees of wind chill.
All the best,
Dave.

The physical shortage of space between the top of the PTO and the floor is usually overcome by either lowering the tranny cross member or raising the body tub. I know raising the tub seems a bit overkill but I favor it since it doesn't disturb drive angles for the drive shafts. The downside is the 1" of raising results in an almost equal drop in the steering wheel.

Oh dear. Physically modifiying the jeep is not something I want to do. I mean bolting bits on is one thing but raising the tub, no I don't want to do that, I like my jeep the way it is. Besides I'm not sure how I would raise a tilt grill? Dropping the cross member? I don't like the sound of that either.

There is a genuine ex USAF MB down in Licolnshire that has a huge winch under the rear floor of the jeep, an ex USAF mod. The floor is superbly metal worked to have a semi circular bulge across the rear to allow for the drum.

I will look some more tomorrow, and see if I could I not modify the floor with a little 'bulge'

Does Herm the OD guy have a soloution to this problem? that would work for the M38.

Hi Steve,
my interpretation of what Herm emailed me is; if the body is lined up OK it should fit OK. If the body is out of line there might be a problem.
However he doesn't have any 26 tooth gears till around January so that problem is put back a bit.

Which brings me to my next post, why so many different tooth counts in the same tansfer box?
All the best ,
Dave.

Dave,
How do your pads between the body and frame mounts look?

If they are crushed or even gone that could also explain your clearance issue as well.
