hi all. just replaced my water pump on my 1100 and i got a small oil leak thru the weep
hole. i noticed there is an o-ring indent on the tranny cover itself but every picture i
see related to the installation of these o-rings show the o-rings going on the pump
itself before install. [what is up with that] i vote for the indent on the back of the tranny
cover what do you guys think? also should i silicone the rings before install?
yes ---lube the o rings on the pump body. also the pump shaft , helps the seal in the case . if everything is lined up it should all go togather with out a lot of force. you most likeley have to turn the pump shaft to get the slotted end to mesh with the pump drive.
Oil can leak from three places the crush washers , the oil seal on the shaft and the o ring..note I put the o ring on the pump and insert into the case..also the o ring that usually gets pinched the water side not the oil side
