 Posted: Thu Apr 26, 2018 8:33 pm Post subject: F134 rear seal |
 |
|
| Finally have an engine that's sweet after total rebuild. A change of transfer case and it is running quiet and fast. Steve asked me to pick up a new rear seal which was installed and it is still throwing oil. I did a little reseach and found it requires 2 rear seals, a lower and upper. the engine blow-up doesn't show the position of those 2 seals. can anyone pinpoint for me. |

| Just saw a picture of the rear seal in the willys catalog. It is a 2 piece seal with obviously an upper half and a lower half. Is that what they mean by upper and lower. |

There are 4 parts in total for the rear main, upper, lower, and the 2 on the side. |

| If you are still unsure on your seals, my F-134 block is disassembled right now and fresh from the machinist. I can take some picture for you and post them up along with the seals that i have. |

The early L134 cranks used a rope type seal because the crank was machined for a rope type seal. The later L134's and the F134's used the later preformed neoprene seal and their cranks were machined specifically for thos seals.
Both the rope type and the preformed type came as two halves. One went into the seal grove in the block above the crank and the other went into the seal groove in the rear main bearing cap. Then both type also had two cylindrical preformed seals that went in the vertical channel between the bearing cap and the block.
One half of the preformed neoprene seal installed in the lower bearing cap seal groove.
One half of the rope type seal installed in the block's seal groove.

Wes and Dan,
Can't thank you enough for your help. Your posts and photos certainly cleared up the mystery. Part of the problem was that my tech didn't give me the old part and I didn't know what it looked like, but he should have known that the front seal that was sent to me by my supplier was the wrong part and told me. Thanks again from a very old Jarhead.
