Deck removal is extended in the operators manual, which you have the right to view for cost-free on man Deere"s website in situation you don"t have one of her own. (The operators manual doesn"t cover replacing the traction belt.)


The belt rides up over the steering mechanism and also the crossbars for the brake and deck lift.

When the spring is off and also the stress is released, you"ll be able to pull the belt turn off the infection sheave and also pull part slack up towards the front of the mower, which you"ll require in the following step.


I disconnected mine at the front due to the fact that the cotter pins are easier to get to up there. The would more than likely be a lot easier to check out what you"re doing if friend disconnect them indigenous the bellcrank on the steering sector. One of two people way, traction the loop off the engine pulley and also drop it listed below the steering sector.


The belt is trapped between this tiny idler and the frame on the left side of the mower therefore you"ll have to remove it.

After ~ you execute this, the belt have the right to be eliminated by threading it the end from on peak of the brake and also lift shafts. There"s a pawl bar sticking increase on the deck lift tower that you"ll have to work the belt over top of to gain the belt all on the same side. You deserve to see a good view that the pawl in the picture of the idler in step 2. Pull the behind loop forward end the two shafts till the entire belt is clean of the mower.

Thread the new belt over height of the 2 shafts and also work the left next of it over the pawl on the elevator shaft. Put the idler back on next to the left next of the frame.

Thread the belt around the anxiety pulley and also put the guide ago on, climate thread it around the tension idler and finish reassembling the tensioner assembly. The tension pulley-block is bolted through a slot in the stress arm, and also I think this is for this reason you can fine song the belt stress by relocating the pulley earlier and forth follow me the slot. I left mine where it originally was and also it operated fine.

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

Fantastic Instructions! I acquired my 20 year old LT155 rolling again there is no spending $$$. I have actually two tips: 1. Yes, the is challenging 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 with both hands and also could unhook the springs with ease. I might put the springs back in location after installation the new belt in the exact same way. The hooks pinched the strap but I could pull the off utilizing a evil grip. 2. Check the mounting bolts for the engine if you space doing this job. My mower has a Koehler CV15S engine. Every 4 bolts had dropped out and the engine was sitting shed on the frame. This resulted in the drive belt to stop working. That is simple to tighten or replace the bolts as soon as you space replacing the drive belt. If some space missing, they to be 8mm x 25 mm, JD part number 19M7867. Ns will examine them every year now. Happy Mowing!!

Nice photos and also procedure for transforming the traction drive belt. I provided it on mine LT166. Here are proposal to do it also better. Perhaps some text labels ~ above the picture to exchange mail to your great labelled chart in action 1 together I had actually to go earlier and forth fairly a bit and the initial John Deere diagram that I gained from my dealer was UNLABELLED! The dealer also told me the journey belt procedure and even mower deck belt routing is just in the expensive $$$ dealer company manual. Some anxiety springs are an ext worn out than others; civilization often re-adjust the tensioner come compensate for older drive belt stretch. This have the right to make the huge bad feather very challenging to safely remove and also reinstall. Mine to be really strong and too daunting to reconnect for sure in the original tensioner wheel position. My large suggestion is in ~ the tensioner pulley-block re-install step, it may help to (1) mark the current position v a paint pen, (2) readjust the tensioner pulley all the means to the slack position, leave the guide off till the "big bad" tensioner spring is installed, climate make certain to collection tension to store the brand-new belt to run properly. Climate reinstall the tensioner guide. The procedure is often important on car engine belts. Again, fine done sir, and thank you. Also my john Deere dealer found your procedure virtual in a web search.
