The reconstruction begins 1977 (Surprise)

[Mikey]

Well since my ribs are healing nicely I thought although I'm not good enough to get on the horse and ride it
I thought If I take it easy I need to start to fix what is bent etc. and get it back to looking good and ridable condition
I have a question about how to get the bent left ear off the bike and put a new one (thanks @gggGary for all your parts !!!
I'm going to post a few pictures of that part of the bike in the hopes someone can tell me how much I need to disasemble to be able to do that
Bear in mind I'm a bit of a church mouse when it comes to this ( I don't want to tear it so far apart that I can't get it together again 'DO NO HARM)

Do I need to take apart the entire triple tree

and lift it off the tubes
I'm most concerned about that large Acorn nut on the very top
Lets start with a few photos

Bike on center stand
brace or jack uner engine so front wheel is "just" not touching the ground.
remove front wheel and fender,
Loosen the bolt for that tube on the top triple, drop that tube down so that the ear can go out to the side,

 

[Mikey]

The ceter stand is bent so it barely engages so that not funtional at this time

I will have to get the center stand fixed or find a safe to do this
Thats what I needed to know
The triple trees and the forks look good but I will have to take a really close look at the tubes to make sure there not bent
Just put a straight edge on them ( the tubes)
Thanks for the info I can do that !!

On this I take it the center stand should hit the rubber first and at that time it should be close but not touching the muffler
I have a friend with a torch and he's a bit of a machinist so he should be able to straighten that back again

Hey Mikey, so you’re getting ready to get er goin again eh buddy? I looked to see if I had a few photos of the center stand and these were the best I had. I hope they are of some use to you.

Hey also, you might want to consider a Harbor Freight bike jack, I used the heck out of the one I’ve got. Just don’t forget to use tie down straps with it, cause it’s easy enough to wrestle it off of there. And actually 4 straps are better than two.

I think if I take the stand off my 75 it should show my buddy what the 77's stand should look like un bent
Thanks for the pictures guys !!

I recently straightened a bent stand using my neighbor’s hydraulic press. It was an easy job.

 

[Mikey]

My buddy has one of those too

The centerstand tang on an original exhaust 75 is different than the 76 up tangs.

 

[Mikey]

When you say tang is that the arear that contacts the floor or the area you step on

the curved tube you step on.

Got it, time to take it off and head to my buddys house
With the pictures Bob posted it should give us a good look at what it looked like before the crash

Your picture doesn't show it very well, but you're saying the tang is bent, hitting the muffler before the leg hits the rubber bumper? If so then yes, it should be an easy fix, just bend the tang back out a little. And while you're "fixing" the stand, does your buddy have a welder? The tangs on these need to be braced or they break off eventually .....

Another very worthwhile mod is adding grease fittings to the pivots. It's amazing how much easier the stand will operate if kept well greased .....

But, this requires some welding as well. The tube isn't thick enough for the grease fitting so you need to build up a small blob of weld there .....

 

[Mikey]

I'll show him this entire thread so he has a good idea of where things need to be and maybe even put a gusset on the tang

 

[Mikey]

Tang is bent along with the left foot
Friday after lunch we'll get at it

remove front wheel and fender,
Loosen the bolt for that tube on the top triple, drop that tube down so that the ear can go out to the side,

To take off the wheel (remove the axle) the book says take off the locking nut (castle nut right side) or remove the 2 bolts on the bottom of the fork tube left side
I can do it either way but what is the hole on the left axle do for getting the axle out (the punch is in the hole ) put the punch in the hole and turn it off
