X758 Deck leveling problems solved

[Timbucktwo]

I put the spacers between the cleavis and the nut that goes on the end of the screw. I think I'm going to do the rock shaft as well.

What is the tunnel decal?

Welcome to TBN

Don't follow why. Are you saying that the resulting height is just not at 2.5 inch, or my interpretation that you are saying the deck is not level by ½" side to side??

The spacers added the height to get the deck leveled at 2.5 inches, but now the deck is going up into the chassis to far and hitting the cam. I can't move the cam past 3.5 inches when the deck is raised. Requires a lot of futzing around and I'm kind of afraid things are going to start really going south. Problaby time to just replace the rockshaft for me.

If things go as planned I will set the rockshaft on a flat surface and take pictures to document. I plan to go through things pretty thoroughly as I don't have to rush. I use the Ztrak for most of the mowing so the x750 can sit idle without a rush.

Spacers under the head of the adjusting screws? I did the same. I think I am going to try the rocker shaft replacement and see what it does. I'm also going to replace my tunnel decal as mine has 2.5" cut at the 12 oclock position. Seems they updated this and 3" is now at the 12 oclock position which is much closer to what it should be.

What is the Tunnel Decal you mentioned? I'm not familiar with that?

mine has the 3 inch at 12 oclock and it still is off by 1/2 inch. I'm getting a creaking / groaning noise when I raise the deck. somewhat intermittent but it does it atleast 90% of the time so I will look into the PIP for the bushings.

I had it wrong in my mind. My machine has 3" cut height indicated at 12 oclock. I saw somewhere on a post that there were different decals so I started to look.

If you zoom in on #22 which refers to M174354 you will see that the 10:30 oclock is 2" 12 oclock is 2.5" and 2:30 oclock is 3" This puts the deck 1/2" higher than the decal that is on mine so it should be pretty close. Its tough to see in teh picture, but the 2.5 that is used to level is clearly at 12 oclock. I posted a link to another forum that had a better picture.

I don't know if I can post a link to another forum without getting deleted, but pictures here: X700 series mower height label / Deck leveling (x730)

I had the creaking noise on my x734 and posted my resolution which can be seen at post #20 here —>X738 54HC Gearbox "Rubbing" Issue?

thanks for the tip. I have lubed the bushings with white grease in a spray can but It didn't seem to help and the problem with lubing is that all the dust and dirt now sticks to it. I had it in to the dealer and they added all sorts of washers at the pivot points to try and limit side to side play but nothing seems to help. Last fall i took all those washers out hoping it would help but it did not. The PIP is specifically about those bushings and the small ones up top I am going to have to stop by my dealler and ask a few questions
