Tran. leak at drive pulley

[BruceH 7]

I had an AC 314 with 3 speed trans. and variable speed pulleys. The trans. has started to leak fluid from around the shaft that the drive pulley is attached to. Has anyone replaced the seal that I assume has gone bad? If so, what is involved? Thanks for any input

I have an AC 314 not had one. Better keep my day job, I can't write either.

Past, present - what's the difference? We'll try and help you find out what you could have, should have or would have done any time, any place - as long as it's Simp/AC. And all for $.02 - $.18 worth. Actually I'm not sure Bruce - it can be done without complete disassembly but you may have to remove the side plate to gain access to the seal, which would involve removing most of the shuttle sys if I remember correctly.

Bruce, That seal leaking is really a sealed bearing assy. like what is inside the mower. Dollars to donuts it's leaking because the trans. input shaft is worn and won't hold the oil in any more!This is not a job for the faint of heart.The heavy vari-pulley has probably worn the trans. shaft out of round,causing the leak. dlc

Thanks Jeff and Dave for your responses. I have another question as a result of your responses. Ilooked at my service manual tonite and in the power train sectionit talks about disassembling and reassembling the tranny. In here it says that the gasket and the cover are reassembled to the tranny and then the oil seals are installed. It looks like the oil seals are the last step in the reassembly process and are done from the outside after the tran. case halves have been put back together. I guess my question is, are these oil seals used only on the axle tube or are they also used on the tran. input shaft? If they are used on the input shaft that could be my fix (sounds too simple though). Any addt'l comments are greatly appreciated. THANKS!!!!!
