I have come to the conclusion that my CC LT1045 with 46" deck is in need of some maintenance and repairs.

First off, I bought the mower new in 2007 and will admit that I have never pulled the deck and therefor never lubed any of the bearings. I did have it in one year for a "checkup and tuneup", but who knows if they even wen't so far as to do any real lubing. So, anyway, the deck seems awful loud and rickety and I want to bring it back up to good operating condition. I will pull the deck and look things over, but I was already thinking that I would be replacing the three blade spindles and belt. I will also replace the two idler pulleys if they look like they are worn out as well. Then, a blade sharpening. So what else should I look over and consider servicing or replacing while I have the deck down?

Any advice or guidance is appreciated.
Thanks, Bruce

The rebuild kit link you posted from Amazon should be all you need. You also need to start greasing your spindles on a regular interval ( a couple pumps of grease every 20 hours of mowing time) or you'll be needing another rebuild kit.

I just finished the rebuild and I am verrrryyyy happy with it. At first, after removing the blades and spindles, I didn't think they seemed too bad. But after putting the new ones on and starting the mower and engaging the blades, wow, a biggg difference. It is so much more smooth and much quieter than it was. I lubed up the spindles prior to installing them, so they are good for a while now. I was kind of surprised to find that they were "Unlubed". I pumped quite a bit in each one before it started to come out of the weep hole. I wonder how many people just swap them out without lubing them???

Anyway, I wanted to list the specific parts that I used because that "kit" that listed above was for the 2008 and up mowers and I have a 2007.

Spindles, blades and belt.

Larger idler pulley:

The nuts on the blades were a ***** to get off. It took a 1/2" breaker bar with a pipe extension to break them free. Getting the deck back on and hooked up was a bit of a pain and getting the belt back on the pulleys was a *****, but all in all, perfectly doable for the average joe and well worth the time, effort and money IMO. I plan to keep up on the lubing and have these spindles outlast the rest of the mower.

An impact wrench should be your "go to" tool for removing and replacing blade nuts, it is what almost any repair shop uses. You can get them in either air operated or electric. If you really have some spare change, get the hydraulic impact ones.

There are a number of tips and tricks one learns over time about repairing decks. First, the self tapping screws that hold the spindles to the deck should be tossed in the spare parts bin. Use a 5/16th inch tap and thread the spindle mounting arms. Then get a longer 5/16th inch bolt and a nylon lock nut and use those to mount the spindle to the deck. Use of never seize is recommended on any threaded bolt/screw. The use of never seize on the bolts for the blade makes it much easier to remove at some future date. Fill the spindles with grease before you mount them to the deck. Another hint is to use a straightedge across the sheaves to ensure that they are all at the same height. On some decks, I've found the best tool is a pipe wrench to grasp the idler sheave arm to loosen the belt.
