Tranny (465) gurus - cant get third....

[mtweller]

I'm thinking this whole deal could explain my 3rd gear issue as well. That is where the two sections of the mainshaft come togehter, and if there was play it many not be able to fully engage the gear. Make sense?

Thanks for the feedback, I'm going to have to go back to the drawing board on the adapter plate.

 

[Pin_Head]

Yes, that could explain it.

Rather than making a new plate, maybe you just need to make a ring that is (roughly) the thickness f the plate and has the same ID as the outer race of the bearing. That way, when you tighten the transfer case up, the ring will fill the space between the case and the bearing.

 

[mtweller]

Thanks PinHead, that is exactly what I was thinking about the ring. I'll have to get w/ my machinist once I get this thing out. He'll note the changes and modify the design for if and when he cuts another one, it'll already be right.

Thanks to all!

There might be a small market for the plate adaptors, as long as you can beat the price of the only other vendor, Classic Cruisers.

 

[mtweller]

I doubt I could beat the price. There is just too many labor hours in cutting one for a one man shop. That was my original intention, but quickly the hours added up in the shop.

I did want a couple of things that I got though:

1)The plate is 1" 6061 Al, which is lighter than the steel version (less drivetrain weight)

2)I clocked the tranfer up some, so I have a skid that is flat and hangs no more than 2" below the framerails

3)With a 1" plate, the gear has "overlap" so I could employ a wristpin in the "thick washer" much like a 420 swap (less chance of it backing off)

4)It was fun to work with the machinist and I learned a $hitload

Here's a sideshot of the skidplate mounted.

 

[cruiserjunkie]

how much did it end up clocking the t case? looks like you did raise the skid 2 inches or so. I'm thinking alot about this swap and wodering if 2" is worth the all the trouble over the classic plate always so many questions in my mind before spending my money and I always seem to make the wrong choice and spending double in the end. Hope the retainer fixs yopur problem

 

[mtweller]

This is not the Classic plate. I think the Classic plate, correct me if I am wrong, retains the factory clocking. I think I gained about 2-3", but I did not measure.

Once you drive with the deeper gears, you'll know it was worth it!!

Only after you do something like this, do you realize the fact emboldened above.....




(less drive train weight)

That is funny. Aluminum is easier to work with in this application.
Did you use steel thread inserts or just tap the aluminum?






Did you take any pictures of the adapter, this overlap and your locking washer?



Glad you had fun!

We debated using HeliCoil inserts, but decided they aren't necessary. The plate is sandwiched and is not exposed much loading. So, we just drilled and tapped the aluminum.

Here are a few pics, albeit not that great of ones....

and more...

Last few

A couple of things:

1. It would be ideal if you could add another bearing in the plate to support the output shaft. This is the way the sm40 plate adaptor is set up. It would seem to required machining on the output shaft to remove the threads on the retaining nut and maybe a sleeve to match the size of the bearing ID. A single bearing puts more stress on the needle bearings in the input gear, since the transfer case drive gear is going to cause the shaft to deflect.

2. On the washer and bolt assembly: The roll pin should extend through the fender washer or it should be welded to the thick washer so it can't turn and allow the bolt to back out.

 

[mtweller]

Thanks PinHead for the suggestions -

1. While agree in principle, the other 465 plates (Woody's, Classic) don't impliment this and I think there are some out there with a lot of miles on them. Are you saying they should have them too, or you think my design begs for it more for some reason?

2. Thought about this, and I agree. Since I have it out, I'll put a longer spring pin through the thick washer and drill a hole on the fender washer to match. Good idea, thanks!!

 

[jcj_78FJ40]

Hmmm…. So I guess you are saying that your plate adapter is not holding the bearing in place.
Nice looking plate. I’m sure a lot of time and effort went into it. I hope you find a solution that doesn’t require machining a new one.

Did you have any issues bolting the gear on the output shaft using a 1 inch plate?

 

[Pin_Head]

Yes, the other plate adaptors for the 465 don't have another bearing, but from engineering considerations, another bearing would help distribute the lateral load. In the NP 205 and 208 cases, the other bearing is inside the transfer case.

 

[mtweller]

Update: Problem corrected by rolling a piece of 1/8" steel to make a spring loaded ring the right thikness to fit b/w the bearing race and tcase mounting surface. Works perfectly. Sorry, forgot to snap a pic prior to bolting it all back together. However, that has created a new issue I want to check w/ you all about before I put this thing back in! See my new 465 thread if you know this tranny.

for all your help!
