The reason I used a sealer on the cork gasket? refer to the previous picture (before the one say it was OPTIONAL) and note the difference in thickness between the old gasket- .030 and the new one - .070. I knew the new one was a composite, but if the cork thinned out on the old one, the new on might after another 30 years.
Beside - this isn't a rocker cover on a small block Chevy (and some of them I used to seal BOTH sides of the gasket too), how often to you plan on taking that pump off ??
That gasket is a one-time use item and is likely permanently compressed the first time you torque the bolts. It isn't going to return to its original thickness once the bolts attaching the hydro unit to the rearend are loosened.
Gerry...hopefully this will be a first and last time I wind up having to take the pump off! Seriously considered not even bothering (I mean, it's been a slow leak now for around 20 years) but I always worried about it possibly getting worse. And, I'm always (most of the time) up for a mechanical challenge with this old Cub, so thought it'd be worth doing.
Kraig et al... I was responding with my reasons (IIRC) for sealing the other side of the gasket. I'll wait until after my first cup of java next time..
Matt.. and the reason for the original gasket leaking eventually. The bolts were all tight, but that gasket was soaked on both sides. I'm guessing the original cork gasket didn't have any stickum' on either side. I'm still waiting for any reason not to seal both sides.
Lots of good advise on the process, I guess it might be time for an addendum; I wrote lots of procedure manuals back in the day, most of them covered "everything" up until the point someone used them...
Keith - I laughed when I read your comments about a slow leaker and whether to change the gasket. My 129 "spotted" for about 20 years and I too kept putting wrenches to the external pipe. I'm lucky that in the end I didn't ruin one of the fittings over tightening them.
My project for the summer is to take all the hydraulics plumbing off the 149 and move the lift and all over to the 129. Might even take pictures.
My biggest hangup is concern over the pump on the 149 since other than rolling it off the trailer, I don't have much feel for the condition. I know the lift worked, that's about it. I remember Don T taking a pump apart. Remember that, Digger? ........
I then might consider getting the K 321 rebuilt, if I can find someone I trust.
