Still trying to get the mower deck right

[JimP2014]

I have it the way the parts diagram shows it, and i think it could be wrong? T or F?

 

[JimP2014]

OK I messed up. It needs to be 34,59,145, and 40. I have some of it correct. I have the small idler pulley where it needs to be and the belt guide too. I got 2 right and 2 wrong. So Sears is correct on this I read it wrong. I have that spacer which only works with the tensioner spring where it does not belong.

These are the parts for the small idler pulley:

Okay I just went back outside again it's 7:00 p.m. on Friday night and I found the small idler pulley is attached to this metal bracket that metal bracket has a gigantic hole inside that hole needs to be the Husqvarna special washer and then on top of that the bolt goes straight through that the small idler pulley is already attached to that metal arm maybe it's supposed to be on the other side than that arm I don't understand what's going on. Maybe revisiting some videos on this deck might help but the way I see it the small idler pulley does not mount directly to the mower deck it has a metal arm.

The way I have it is the large idler pulley attaches directly to the mower deck maybe it's supposed to be the other way around.

So I took a screenshot of repair clinic they have it set up exactly the way I do. In fact repair clinic has it 57,56,55 but Sears has it 57,55,56. I have it the way repair clinic has it.

And the reason why it's such a big deal is because when I tighten that bolt down which has the Husqvarna special washer below it it defeats the spring entirely you can't move that pulley anymore which means you have to keep it kind of loose which means there's vertical play in that bracket this is ridiculous

I agree with Rivits's assumption. The black pulley looks tilted towards the fron of the deck. It also looks low to the spindle pulley and the belt is riding high in it. This may be where the noise and heat are coming from. Pull the black pulley again, when the pulley is mounted tight, there should be no wobble in the center hub and very little in the bearing. Inspect the bolt's threads. Are they worn down? Not being a hardened shoulder bolt, the pulley may have worn the bolt, hence the wobble. Then inspect the pulley's mounting plate. It's probably noy level. Either bent or the mounting point is bent, or worn, or both. Get that plate straight should raise the pulley into alignment.

OK here is the latest image from 30 mins ago. I see what Freddie21 wrote and so this pulley is tilted, I could see it when I was outside. I do have a perfectly good spare also.

When I was looking at it, I can't bend the frame but I was thinking about a shim that might be tilted that will square up this whole setup. Also I have one extra washer underneath the pulley and it might not be needed. I am thinking shim because I can't bend the frame. And the shim never spins anyways, so once it is set in place it should stay like that?

Thanks,
Jim

Here is my latest idea, remove the customer supplied washer meaning me, and somehow put a shim maybe on one side like 1/2 a washer and then tighten everything down?

Somehow get that carriage bolt to tilt in a slightly different direction but the mower deck frame is unchanged?

This is a video of the left side of the mower deck + the large pulley and one of the spindles can be seen in the foreground but the thing to notice is the constant ringing noise the video starts with the blades engaged but about 3/4 of way through I turn the blades off and the ring noise goes away and then I engage the blades again and the ringing noises back so this is other than the belt needing to be replaced I just have a feeling with a brand new belt I'm still going to have the ringing noise so I'm hoping to address the ringing noise soon.

Thanks,
Jim

I believe at least 2 of the Flat Idler pulleys are loose and need replacement .
Put the front deck control arm back where it was and loosen off the Nut to replace it. Level the deck with front 1/8" lower than rear. Belt appears OK.

Hi Gord, thanks for your reply I am working on that. I did find you can't actually tighten down the small idler pulley ARM to much because you end up preventing the spring from working. If you tighten it very tight, here is what happens. The arm that the small idler mounts to becomes perfectly secure with no vertical movement in that arm at all. That is great except now the spring cannot travel as it was designed to do because everything is to tight. Remember that arm is spring loaded and that arm has to swivel and for the arm to swivel the bolt can't be to tight. If you need a parts diagram for what I mean, let me know. Both pulleys need to be tight, the small idler pulley mounts to a lever that then mounts to the mower deck. The large idler pulley mounts to the mower deck directly. And this happens to be tilted and not parallel to all the other pulleys. All these pulleys ( 4 ) of them all need to be in the same plane.
