D2-5U13753 - master pins - please check my understanding

I guess mine's on at the 15t spec : ) My bottle jack is too wide to fit between the pulling bolts unfortunately. I'll need to come up with another plan. If I knew that the hub was spent, I'll just cut it off. At 280 from GG, I'm just about there on time spent...

Cheers,

About 10 years ago, a fellow posted on here of using a bottle jack on the final drive sprocket of a D6. He had an assembly that allowed for the wider jack to be mounted further out but still pull against a narrower set of pins. I looked real quick through my SAVED folder but don't have a picture of it?
Imagine an 8" long bar with a center hole for a push pin, 2 holes for the hub pins, then 2 more holes further out for the rods to go the length of the bottle jack. These would attach to the bar across the back of the bottle jack.
Make sense?

Yes that makes sense Jeff - it'll look like quite a contraption : )

Low cost contraption!
Why rent, if you can build an effective solution!
One that you may very well use again in a different application!

Would anyone be able to tell me if the brake band anchor / lever shaft 4B6691, the one that the anchor / lever rotates on, is threaded in or just driven in? From the parts catalog, it looks like it's just a pin that's retained by that adjacent 3/8 bolt and a tab. If it's not threaded, then I'll heat and pound to drive it out. Mine has a hex head on it like a bolt which is not what the catalog shows so I assume it's a make-fit. Pretty danged tight-sounding when I "tap" on it with the 10# and drift. The brake band lever on it is loose so that's something

On the clutch inner hub, I have the 10t hydraulic press cranked right up hand-tight and heated it today and heard some creaks, so I'll do another couple of cold/heat cycles and see if it lets go before taking more drastic measures

I haven't pulled the ones in the 5u yet but the 5j was just a straight shaft. They where really hard to get out, lots of heat. Can't see any reason why they would be threaded, the tab and bol t should be plenty and they can't go through the final housing very far before they would hit the trans housing

Thanks gary, the catalog shows a shaft rather than a "bolt" but mine has a bolt head on it and what looks like some thread sticking out. When I hit it with the drift, it feels solid, not even close to being movable, even with heat. I'm debating whether to leave this one in since the brake anchor does swivel on it fine. Only thin stopping me so far is that I don't like stuff to not work, and not being able to remove this shaft is bugging me.

Maybe a "Will Fit" replacement?
Can you see anything on the inside that indicates someone cut a thread in the housing?
I always questioned the "straightness" as I have found they tend to come out in one direction only?
Wish I could remember? But think they come out of the case easier than being driven into the case?

I'm usually if it ain't broke don't fix it kinda guy but something about these old cats that just gets under my skin when something like that won't cooperate and throws down the challenge. Since your brake linkage does move you might be ok, but it might just decide to lock up for reasons we'll never know. Some antiseize on that shaft might be worth a lot of peace of mind. I will say that mine were really hard to get out to the point it took days of heat and cool and lots of penetrating oil . Once the shaft was out the goo that was holding them in had actually stained the shaft. I'm going to have new clean shafts made to reinstall mine.

Yeah I'm thinking of drilling it out and have my guy make a proper one installed with antiseize
