Hi , can anybody tell me how to get blades in proper time on my john deere Lt155 freedom 42" deck. I have tried like 10 times,and the blades eventually hit. I see the dimples (dots) on the left blade toothed pulley what other pulley has the dots that have to be aligned, any help appreciated, thanks

Hi,
First there are two different Freedom 42 decks. Version one has the belt in an elongated "L" shape and version two has a belt in an elongated, rounded "V" shape. Both decks have the same pulleys used on left and right except the right has the sheave for the belt from the engine. When assembled correctly, either deck has the dimples on both toothed spidle pulleys though the right ones are covered, but there are similar indicators on them. Basically one side should indicate left to right and the other front to back to be correct. Both decks have a pair of toothed idlers to tension the belts.
It is not just that easy to do correctly. Improper installtion can damage either of those pricey toothed belts (they do use different belts.) Both decks have tensioners which need to be loosened. From there things change a bit. Both decks have lips on the top of the spindle sheaves, so they have to have the belt below those lips to install the belt.
The version one deck starts with the sheaves 90 degrees off, the tensioner loosed, the belt run loosely to both spindles and then to the idlers. The belt is installed on the idlers slowly by starting the bottom edge of the belt on the top edge of the idlers and slowly slipping it downward on the idlers by rocking s spindle back and forth and pusing downward until the belt is fully down. Then it is tensioned, tightened and reassembled.
Version two varies because of the bracket that encases the idlers. The spindles are still turned 90 degrees out of alignment, but the belt is routed on the idlers and the spindle sheave nearest them after first being put on the other side below the sheave. Here the belt is installed with the same rocking motion but onto the spindle sheave. The it is tensioned, tightened and reassembled.
To have what you describe; the blades eventually hit, means a damaged belt or not enough tension, or both. Neither of these belts can be pried on without damage. They are expensive and rather delicate considering their price and use. They job is to time the deck (blades) and to have the blades start hitting means that it is "skipping" timing. This will usually damage the belt and the blades.
Peace,
Clarke

Thanks Clarke, I found what appears to be 2 drain holes on the right side belt pulley, I offset them 90* with the left side put her back together and Is working fine so far,you are very helpful,and I appreciate it very much, cause I was getting very aggrevated with this thing, again thank you.
