Marlin Dual Case Adaptor Install Question

[Ranski]

I started looking at the dual case adapter I recieved from Marlin and notice a slight problem. Before I go breaking anything I thought I would ask what I should do.

The instructions didn't mention anything about this...

As you can see from the pic, my doner case already has alignment dowels as does the marlin adpater.

-Can these dowels be pressed out?
-If so which ones should I press out?
-And in what direction do I press them out? I'm guessing in the direction indicated by the arrows...

I'm leaning toward the dowels on the adpater. I'm worried if I press the ones out of the box I might break a piece off the box.

Any thoughts?

My guess is Marlin put them on the adaptor for a reason. Mine's bolted together otherwise I would go look at it for you.

You may want to search the Marlin board to see if someone else had the same issue.

Wait until Monday and call them

You sure the adapter is not on backwards? Mine won't be here until early this week so I can't compare. I just have two transfers in pieces in the garage. Didn't even take me two hours to knock them both apart. Will probably take me twice that long to clean up the cases nice 'n purdy

Well just in case someone else runs across this "uncommon" situation, here is what BigMIke at Marlin had to say...

I have since followed his suggestion and removed the dowels by using the vise and twisting the case.

That is just because your donor case is worn out and the dowels have been removed and reinstalled in the past. When you take apart a gear drive t/case, there should NEVER be any Dowels remaining on the #1 Housing (Low Range Reduction Housing, aka: Crawl Box). Those Dowels are designed to stay in the #2 housing. But sometimes the #2 housing doesn't hold on to the dowels correctly, or when it was assembled there was debris in the #1 housing dowel hole, or the dowel began to corrode on the #1 housing side, and sometimes the dowels stay attached to the #1 housing, but this is uncommon. 8 out of 10 #1 housings will pull apart without any dowels remaining.

I recommend that you remove the dowel from the #1 reduction housing (Crawl Box housing) and not from out adapter. Our Adapter, like the #2 housing, has a slightly undersized dowel hole so that when the dowel is first installed, it is a "press-fit". The more times you remove something that is "press-fit" the less of a "press-fit" it will have. The #1 housing is not a press-fit, so please use some kind of a punch and tap the dowel out of the #1 housing. You could also squeeze the dowel in a vice, and then twist the housing around the dowel clockwise and CCW while pulling up.​

That is a good one to remember! Nice catch.
