Topic: high pinion in the rear

[possume22]

who is running a  toy high pinion in the rear im needing to but read alot bad about it im trail only i was just wondering who is doing it

[axled89]

what bad things did you hear about them?

[OOPS]

They blow up, Marlin even tried modifying them and they still blew up.

[possume22 [OP]]

i hear the dont sling oil and burn up your bearings and there week because they run on the coast side in
 the rear

[possume22 [OP]]

why did they blow up driving on road or trail

[yota_krawler]

the pinion doesnt get lubricated so it fries the bearing and the pinion gets hot and fails. they would get you home if you have one in the front that you could move to the rear if needed but its not recomended to run in the road.

[possume22 [OP]]

ill be offroad only just three or four miles in an entire day i dont think that would fry the bearings 

[Cheesemaker]

This is something that many have tried to get to work.  Only to have it fail on them.  Period.  If Marlin can't get it to work, then it won't work.  Unless you got some serious coin to be replacing R&P and bearings every time you go out.


If you seriously want a HP then look for some Dana 44's.

Go for it, when it blows up do not say we did not warn you.

Don't do it.

[kneedownnate]

read a lot bad about it

When people make a statement like this and admit knowing why people say not to do something, it typically means they're looking for the 1 person who'll say they'll be fine to affirm their desire.

Go for it

Just about sums it up. I say go for it and write a report on it so that we all can see the benefits of doing this swap, or not

Here, here.... I second that statement!!!

With a high pinion, (I was told that) when its in the front, its a reversed cut gear so when it is in the front axle it is having contact on the DRIVE side of the tooth.

If it is put in the rear then it is going to be driving on the coast side, which would be weaker, as well as the bearings not being lubricated.

Why do you feel you need to put a high pinion in the rear?

[zippo]

You could always pack the bearing like a wheel bearing if it was only a lubrication problem.... It is not.

I have always heard and been told it has todo the it being a reversed cut gear. It's like driving in reverse all the time for your gear. Its just not designed for it...

[burnyota]

not to get off topic..but how bout a KOH in reverse..just to really see where all that money is spent

[kneedownnate]

The problem with your theory is the bearing is bathed in oil, not sealed.

Lay off the booze when typing dude.

I was wondering what xtreme 4x4 was doing when they built the rear steer for their Toyota buggy using a hp third.  I assume that flipping the housing doesn't solve any of the problems since it's still running on the coast side?

I dont even remember seeing Ian finish that thing.

[79coyotefrg]

why did they blow up driving on road or trail

why?  you answered your own question

i hear the dont sling oil and burn up your bearings and there week because they run on the coast side in
 the rear

dont be stupid,  get a hi9 because you wont have your hi pinion long

[zippo]

The problem with your theory is the bearing is bathed in oil, not sealed.

If it is getting bathed in oil then lubrications isn't going to be an issue. If it is not the packing the upper pinion bearing would work.

[unclejpl4x4]

just me :2cent: but nascar runs a pump/cooler in there rears i don't see why that would not work.

[kneedownnate]

If it is getting bathed in oil then lubrications isn't going to be an issue. If it is not the packing the upper pinion bearing would work.

Ok, let me simplify it a little by asking you an easy question:  is the bearing sealed?

If you answer no then you'll easily see why I'm right.  If you answer yes then... well, I don't think I need to finish that statement do I    And I think you're perhaps thinking too simply of the issue.

[TacoRunner]

Joey does not run one in the rear, he is messing with you. I know this for certain. Other than a D60 or Ford 9", stop thinking about this.   Think of it this way, if this were a do-able upgrade. Dont you think that everyone and their mother would be running it. Marlin and everyone here would have done this years ago. 

[yota_krawler]

i fully agree
