Well, I decided to do some much needed maintenance on the FJ80.
I've had an oil leak for sometime now and I've never been able to pinpoint the source of the leak. I've taken a top down approach to gasket replacement to isolate the well noted 3FE oil leak. The valve cover gasket, side pushpod gaskets have been replace, as well the oil pan gasket. At last, a break in time to replace the Rear Main Seal (RMS).
Friday night: start with raising the 80 and taking off the components per the FSM, no problem.
Saturday day and night: I don't have a suitable jack to lower the tranny so it's off to Harbour Freight for a larger jack and a friend was kind enough to bring a tranny stand for the jack that I just bought.
Now then, I've got the 80 as high as the jack stand will allow, but it's not high enough for the tranny to slide out from under the rig. F*$k'in A.
Next I carefully orchestrated the holding pattern of the tranny under the rig by securing each end. Then with it steady I removed the tranny jack stand and slide the smaller jack under the tranny. Next I lowered the tranny with the small jack until I could get the tranny on the ground to were I'm able the slide it from under the rig.
Now the investigation can begin on the origin of the oil leak. With the tranny out of the way I found that the RMS had signed of oil leaking. From the three attached pics you can see the lower portion of the tranny support plate is covered with hardened oil deposits. Also, the two bolts that hold the dust cover in place are covered with oil.
But I'm not really convicted that the RMS is 100% responsible for the oil leak. I had a suspicion that the back of the oil pan could play a roll in the oil leak also.
Well as I mention before, I have replaced the oil pan gasket once alreay. The gasket I replaced before was one from SOR and it was a four peice gasket. After I replaced it the first time it still leak as before.
Well now that I've got the tranny down I can replace the pan gacket with one from a dealer, I one peice design, I'm already feeling more comfortable.
Well, on the trip to Harbour Freight I told the friend that when I drained the transfer case, ATF can out of the transfer case. He said that he know of similar experiences with this and said that the output shaft seal on the tranny was leaking. Sure enough that was the case. Pics will be posted later.
Well, now comes time to take the RMS out. I take it out and notice that it's worn but not that bad. No solid evidence that it's the culprit, but at least it's out and I can rule it out. Well, almost!! In putting the damn thing in I bend one side. The seal is in but there's deformation on part of the radius. RMS replace x2.
Considering it's the 4th weekend and the dealer will not be open until Tuesday I'll have to wait until next weekend to put the tranny back it.
Okay, so here's a list of the components I need for everything I've got to replace or replace due to it being found missing or I broke it taking the tranny down.
