Putting L3400 HST back together after splitting

[Walt Dancing Pines Farms]

I split my L3400 HST to replace the pto cam(dog) clutch. I'm putting it back together and am struggling to get the coupler that connects the main shaft (just below the pto cam clutch) to line up during re-joining. It's tight splines with tight tolerances. Does anyone have experience and know how to get the coupler on?

Thanks

Walt

Patience and smooth concrete floors go a long way to helping. So does an experienced gear head helper.

There was another guy that tied a string around the shaft so that he could line it up by pulling on one side or the other to spin it.

Did you take photos of this?? I'll have to do it one day....

I have the first two. Are you nearby?

I had the string thought. Maybe I'll try it. I've made videos of the entire project.

I think he wrapped it around twice. Once it's lined up - just pull the string out... pretty light weight string. (thin)

Would love to see the videos!!

Re-reading your post, did you know if he wrapped the string around the coupler or the shaft?

Around the coupler.
Are you moving the the front to the rear or the rear to the front?

Thanks. Pushing front into the rear.

Depends on you're setup.
I put them back together till the splines touch the shaft, then a couple wiggles on the rear will pop it into place, it's a very small movement normally.
Had one that put up a little fight, just jacked one tire off the ground and little tire spin lined it right up.

Thanks so much!

I have the rear on blocks and the front on a floor jack. I might can get some wiggle in the rear. If not I'll try jacking on rear wheel.

So with this method no need for the string on the coupler correct?

Yep, no string needed!

Only a 20 hour car ride away. What's for dinner?
