m47 maintainence while out of car?

[jkior]

As mentioned in another thread, I'm turning my auto dd into a manual. While I have the m47 out, is there anything I should do to maintain it? I'm replacing the clutch disk (my brother learned to drive on this one so it's pretty much dead) and although I haven't opened the gearbox up yet, I plan to completely degrease and refill with mtl, probably. It's been mentioned that the primary problem with m47's is lubrication difficulty and that overfilling them will make them last longer - is there a limit to this? i.e., what's too much oil?

So, the question --> is if there's anything important to do before bolting it in?

Make sure the shifter linkage coupler is in good shape, it's easier to get to with it out, otherwise not much else to do, unless you want to change the front input shaft seal, they don't usually leak though.

overfilling is indeed a good idea... I don't know how much oil you'll need...
too much will cause excessive drag and problems with seals.

Hi

Do the front and rear seals and the selector sharft seals while the box is on the floor. and change the clutch & The oil to. I did a short shift conversion on mine as well

The reverse lights switch is a LOT easier to get to when the trans is not installed. BTDT. I don't think they fail particularly often, but if it does, you'll wish the trans was on the floor.

A complete gasket ansd seal kit is available from FCP for about $25.
My seemingly good looking shape M47 was scapped after I pulled the rear cover to find a pile of broken teeth. There was also a buckled gear spacer visible from the top cover once I really started looking at it... Anyway the one I had was obviously abused but it is a good idea to at least pop the covers and have alook before installing and then replace the gaskets and seals.
