Transfer case shift knob cover

HelluvaEngineer · May 24, 2020

I'm finally getting around to cleaning up my M1009 interior. I removed the transfer case shift cover, which is cracked (looks like it caught a boot or such, a few times). I noticed that there are wires around the shifter, clipped, no light in the spot for the lightbulb, and the clear acrylic sliding indicator part is broken off where I assume it goes to the lever. I also assumed there would be some springs or something to help it follow the lever but I haven't completely disassembled it. In other words, everything is pretty much broken or missing.

Is there a diagram of this assembly? I checked the TM and it didn't help much. Is any of this standard or did someone go to town clipping lightbulb wires, or was the assembly neutered vs some civilian version?

I'm also wondering if someone makes a simple aftermarket boot and a shift knob indicating the positions.

Thanks!

The wires are probably for the 4-wheel drive light as the CUCVs didn’t come with the light bulb for the indicator. I have a later 80s/ early 90s shift knob from a Chevy truck with the indicator button from a early 90s Dodge Ram.

Looks sharp. Thanks for the tip on the parts. I'm considering tossing the entire assembly for a simple boot.

Quick tip on the 4WD light wires. You can clip them and run them up thru the firewall and eliminate the wires on the floor inside. And I would trade for a new shift bezel if you want. I see knobs in Nissan Pathfinders have the same 4wd shift pattern. I use the knobs on other equipment and lawn tractors. They have nylon threads and fit tight when you thread them on the CUCV shifter. Be Safe.

Ah. I'm in the process of removing the ancient rubber "carpet" in my M1009 and just noticed these. Thanks for the tip. Plan on extending the bedliner into the drivers area after filling some rust holes in the floor edges.

I found the following cheap product on Amazon for the transfer case knob that has the correct pattern on it:
"Round Ball Style Transfer Case Shift Knob for Jeep Wrangler YJ JK Gear Shifter M8 M10 Adapters."

The threading is all wrong though (the M1009 has 7/16"-14 coarse to the TH208 )
Going to try and drill out + tap one of the metric adapter sleeves. The thing actually feels heavier than the stock ball which is a plus.

Eh. I ended up making my own helicoils. (wall diameter too thin) Drilled threaded insert out of new ball, ground the aluminum nut from the stock ball and epoxied it in place. It looks better than the picture.

I also "rebuilt" the housing.
1) Remove the 35 year old peanut butter grease
2) Took a red paint marker to the faded orange indicator
3) Add some white lithium grease to interior plastics.
4) Add some woowoo 304 aerospace protectant to the rubber boot and work it in.

The casing exterior doesn't look great, but an improvement. Mine also has an unpopulated "space" for a bulb to illumiate the indicator, so seems like a cost cutting measure. I shined a flashlight into the bulb hole and it looked pretty good, however adding a bulb seems like too much work for the result, i'd rather finish the "important" things like keeping her running.
