I want to replace the rear main seal in my D17 and also the front. I have the original owners manual and I have a general idea of what to do, at least on paper. Can anyone tell me the order of operations that I will have to do this. In order to do the front I have perform a front split, but then to do the rear I obviously have to split the engine from tractor. Im thinking I will need a engine hoist unless I can do this without splitting the front first. Id like to hear from anyone who has done this. I helped my dad work on this tractor when I was a kid, but it was a long time ago and I dont remember the details.
thanks, any advice is appreciated

I'm in the process of replacing my pistons and sleeves. The front split is pretty easy. Your power steering fluid will leak when you disconnect the lines, so you might want to drain it first.

| If it were me, I would take the time and make a nice set of frame rail supports with some heavy casters on them. I made one for my 45 diesel to take the engine out and it worked really nice. There's alot of weight here to support and without supporting things properly, you are just asking for problems. You can use it then to support the two frame rails on either side of your engine, and then remover the front tires/bolster etc, to get at the front seal. I can't remember how much clearance there is around the crank pulley to get at the front seal, you may have to take the front engine support off to get at the front seal and replace. That is the easy one. then you can use the same splitting stand that you made to support the frame rails and front end and then block up and support the rear half of the tractor and make sure to block the rear tires really good so the back doesn't move. It's not an easy project you're undertaking but it can be made alot easier by taking the time and making a proper splitting stand. Hopefully someone on here will post you some pictures of the ones that they have made. You don't have to be as fancy as some people but make sure they are solid and can support things properly. Also make sure they either pick up multiple holes in the frame rails or you run an angle brace back up somewhere so when you roll things forward, it doesn't want to fold over on you. |

| Thank You for the advice. I think there is still some stands that my dad made up at the farm. I will see what I can do with them. What else should I look at when I have the tractor apart? Is there anything else that will probably need replacing? The only work I've done on this tractor so far has been on the top end, rebuilt head. |
