The traction belt is the one the delivers engine power to the transmission. Begin by removing the deck and raising the tractor increase so you have the right to work under safely. Deck removed is extended in the operators manual, i m sorry you deserve to view for free on john Deere"s website in situation you don"t have one of your own. (The operators hand-operated doesn"t cover instead of the traction belt.)

The belt rides up over the steering mechanism and the crossbars for the brake and deck lift. At very first glance it looks prefer you"re walk to need to remove every these things, but you don"t have to. The just thing you"ll must do to obtain the belt clear of these contents is disconnect the steering tie rods.

The tension spring is hooked around a bushing top top the idler and also a notch on the stress arm. Eliminate the spring to release stress and anxiety on the belt. You"ll want the brake in the released place for this step. When the spring is off and the stress and anxiety is released, you"ll have the ability to pull the belt off the transmission sheave and pull some slack up towards the front of the mower, i m sorry you"ll require in the next step.

I disconnected mine in ~ the front due to the fact that the cotter pins are easier to acquire to increase there. It would most likely be a lot simpler to view what you"re law if girlfriend disconnect them indigenous the bellcrank top top the steering sector. Either way, pull the loop turn off the motor pulley and also drop it below the steering sector.

The belt is trapped in between this tiny idler and also the structure on the left next of the mower therefore you"ll should remove it. Usage a 13mm socket to loosen the seed and shot not to shed the bushing that the feather hooks to. Friend can get to the head that the bolt to traction it up and out by reaching through the opening where the steering sector gear is located.

Use your 13mm socket to remove the tensioner idler wheel then remove the overview from the tensioner pulley to complimentary the belt indigenous the tensioner assembly. After ~ you perform this, the belt can be eliminated by threading it out from on optimal of the brake and lift shafts. There"s a pawl bar sticking increase on the deck lift column that you"ll have to work the belt over optimal of to obtain the belt all on the very same side. You can see a great view the the pawl in the picture of the idler in step 2. Traction the behind loop forward end the two shafts till the whole belt is clean of the mower.


Thread the new belt over optimal of the two shafts and work the left next of it end the pawl ~ above the background shaft. Put the idler earlier on beside the left side of the frame.


Thread the belt about the stress and anxiety pulley and put the guide earlier on, then thread it roughly the anxiety idler and finish reassembling the tensioner assembly. The tension sheave is bolted with a slot in the tension arm, and also I think this is therefore you deserve to fine song the belt stress by relocating the pulley ago and forth follow me the slot. Ns left mine whereby it initially was and also it operated fine.


Thread the belt end the engine pulley at the front and the transmission sheave at the back, then placed the stress and anxiety spring back on to stress the belt. Make certain the new belt is routed properly, reattach the steering tie rods, and also you"re ready to put the deck earlier on and put the mower ago into service.

Fantastic Instructions! I gained my 20 year old LT155 roll again without spending $$$. I have actually two tips: 1. Yes, the is complicated to take care of the springs. Ns took a nylon strap around 3 Feet long and placed it end the hook of the springs. I gripped the strap ends through both hands and could unhook the springs through ease. I can put the springs earlier in place after installing the brand-new belt in the exact same way. The hooks pinched the strap yet I might pull the off using a angry grip. 2. Inspect the mounting bolts because that the engine while you are doing this job. My mower has a Koehler CV15S engine. Every 4 bolts had actually dropped out and also the engine was sitting shed on the frame. This resulted in the drive belt to prevent working. That is easy to tighten or replace the bolts as soon as you are replacing the journey belt. If some are missing, they were 8mm x 25 mm, JD component number 19M7867. Ns will check them each year now. Happy Mowing!!

Nice photos and also procedure for an altering the traction drive belt. I provided it on mine LT166. Right here are proposal to do it even better. Possibly some message labels on the photos to exchange mail to your fantastic labelled diagram in action 1 together I had to go earlier and forth rather a bit and the initial John Deere diagram that I gained from my dealer was UNLABELLED! The dealer even told me the journey belt procedure and even mower deck belt routing is just in the expensive $$$ dealer business manual. Some anxiety springs are an ext worn out 보다 others; people often re-adjust the tensioner come compensate for older journey belt stretch. This deserve to make the large bad feather very daunting to for sure remove and reinstall. Mine to be really solid and too difficult to reconnect safely in the original tensioner sheave position. My big suggestion is at the tensioner sheave re-install step, that may help to (1) note the current position through a repaint pen, (2) readjust the tensioner pulley all the way to the slack position, leaving the guide off till the "big bad" tensioner spring is installed, then make sure to collection tension to keep the new belt running properly. Then reinstall the tensioner guide. The procedure is often important on auto engine belts. Again, fine done sir, and thank you. Also my man Deere dealer found your procedure virtual in a net search.
