|
|
It appears as though I have a leak between the case(7375051) and the cap(sp-18-19-33) on my transfer case. I recently replaced the seal(500068) and reassembled and refilled with fluid but it seeps out. My question is are the shims(7373158,7373159,7373160) supposed to seal things up or should I have applied some sealant between the shims and between the shims and cap and between the shims and case? |

Sure looks like the fluid is coming from between the shims but I will wipe it down real good again and observe it closely and make double sure. |

Let the jeep sit for a couple of days checked it today and the leak has slowed considerably but I am thinking this is due to the cooler weather and the gear lube being thicker. Still see some dampness near the shims. |

I don't know if this is applicable to your problem but I had leaks around my yokes. It turned out that the seals I was supplied were Chinese made and did not fit tight around the end of the yoke. I had put sealant on the splines. I was at Mullins and he showed me the difference in fit between what I had been sold and the American made seals and the fit was much tighter. I replaced both seals and my leaks stopped. _________________ R G Mutchler

I used a light coat of copper coat spray on the shims when I assembled mine. It added a slight amount of thickness to the stack but it will still well within specs so I didn't remove a shim or clean off the coating. A very light dusting is all I did.
The yoke is more than likely leaking. Did you use RTV on the splines of the yoke? |

Yes I did apply rtv to the yoke splines but I am 99% sure the oil is leaking between the shims. I wipe that joint good and dry then the area will gradually get wetter and wetter until it forms a drip it may take a few days but it will eventually drip although it has slowed considerably which I attributed to the cooler weather and the gear oil thickening up. |
