I've got the front axle out of my dad's CA and have repaired the pivot pin. I was planning on changing out the leaking oil pan gasket down the line but I thought I'd tackle the oil pan while the axle is out of the way.
Are there are any things I should look for while I am doing the gasket changeout? Are there any tips or tricks that I could use in the process?
I've got more areas to tackle along the way but I thought I'd work my way up.
Thanks in advance,

to keep the gasket from moving, many will "glue" or use RTV on the gasket face to stick to the pan.. let it setup overnight so it is "STUCK" ......... then install on the tractor. Permatex or similar works good on the block edge. If you use RTV, don't get too much and have it squeeze out and get into the oil pump screen. ------------- Like them all, but love the "B"s. |

| I use Indian Head shellac to fix the gasket to the block. This way there is no chance for excess silicone to get into the oil pump. This is also a good time to check the oil pickup for sludge or a plugged screen. Look for metal filings too. If excess filings are seen in the pan, it is time to find out why. |

In replacing pan gaskets on all types of engines I have always glued the gasket to the pan and placed the pan on the block dry. The pan can then be removed without replacing the gasket. Care has to be taken in preparing the block surface to make sure no leaks will start where parts/covers bolt to the front and back of the block. Not wet sticky areas at the time the pan is bolted on.

3M Super Weatherstrip Adhesive works great to glue the gasket to the pan. Before you do, make sure your pan is actually flat. Many times the previous guy got carried away tightening the bolts and bends up the pan sealing surface. If it is warped, straighten it with a hammer on a flat surface. Clean every trace of oil/grease off the pan and block sealing area with brake cleaner. If you look at Dick's pic, you'll see 4 joints. Put a small dab of RTV on each joint. More is NOT better here. The silicone RTV that smells like vinegar is a very poor choice here. Over time it will corrode metal surfaces, and it's greasy and will allow your gasket to squirm. The best stuff hands down is Ford TA31 or GM 88861417. These are both RTV and adhesive. ------------- "Any man who thinks he can be happy and prosperous by letting the government take care of him better take a closer look at the American Indian."
