I have been working on a Cass 300 for several months now, I"ve pulled the head and ground the valves etc... I'm in the process of removing the oil pan and I can't get it out. There is a "A frame or brace", I'm not sure what it is called that bolts to the rear of the fly wheel housing and to the front axle. It keeps the oil pan from dropping down far enough to clear the oil pump. It looks to me the front axle may have to come off to get the oil pan off. Man I hope not. There must be a trick to removing the oil pan. Does anyone know what this trick is? Thanks in advance for your suggestions.

You will have to remove the A-frame brace and front axle. Its really not that much of a project. I recently had to remove my oil pan also, due to low/no oil pressure.

Is it possible to pull the pivot pin in the center of the axel. I have a grease fitting in the end of it now, If I remove the cross bolt will the pin come out?? It would be nice if it did. Then the axle could just rotate and the A frame would drop down. Also, it looks like there are four bolts holding the complete axle frame to the front gear box. If I remove those four bolts how difficult is it to get it back into the right position and aliened with the gear box.

Don't bother pulling the pivot pin. You have to remove the 4 bolts and drop the bracket and axle. If you just removed the axle and left the bracket in place, the position of the oil pump and pickup tube would prevent the pan from being removed. Its a total of 8 bolts to drop the entire assembly. Two holding the a-frame bracket under the belly, two holding the a-frame to the axle, and the 4 holding the axle bracket. First, remove the two bolts holding the a-frame to the axle. Then the two holding up the aframe bracket to the belly. Do not remove the pivot pin on this end either. Your A-frame will now be completely out of the way. Make sure the tractor is completely secure before removing the axle. With the tires off and draglink (or power steering ram) from gear box to spindle arm removed, you are now ready to drop the axle. Remove the 4 bolts, and the axle drops right off. If you have a floor jack, it is very easy to remove and also to realign when putting back together. I'm no tractor mechanic--and it was still pretty much a breeze once I got past the thought that the axle had to come off. I don't know about other type axles, you didn't mention if yours was the adjustable type. There may be differences in the procedure, but I would bet that you would still need to remove the axle and bracket to get the pan off.

Wow, I have the adjustable axles, the A frame is welded to a tube over the axle. I do have the floor jack and can see how this will work ok. I'll go and look at this again tonight.

Thanks for your comments.

I should have said that that procedure applies to a non-adjustable heavy duty axle. It is still very close to what you will need to do. Keep us informed how it goes.

I cut some bolt holes in two pieces of angle iron and bolted them to an oak 2x12 the correct height. Then I bolted my plank under the tractor. Then I rolled the front end off.

The service manual shows where to bolt the stands to split the tractor and how to make a set of stands.
