About this book
Expectant mothers snapped up Great Expectations: Your All-in-One Resource for Pregnancy & Childbirth (135,000 copies sold), and reviewers praised it for its warm, reassuring voice of expertise. This is the logical follow-up, an innovative baby book that will guide and reassure new moms and dads through every nuance of the first 12 months of life with baby. Of course, it maintains all the design elements that are the signature of the Great Expectations series and have proven so appealing: innovative graphics; clear-cut, contemporary styling; and sensitive drawings of babies as they develop month-by-month. The text, too, continues that same friendly, supportive, parent-to-parent tone of the earlier book—but now with dads playing an integral role. Inside, there’s a plethora of information on the nuts and bolts of feeding, diaper changing, and immunizations, as well as cutting-edge research on baby intelligence and development, nutrition and medical care, and insights into the dynamics of the parenting process. Checklists, bulleted sidebars, and quick-reference tables speed up the process of finding needed information. Unique tables in the extensive medical reference section will present the gamut of symptoms, so parents will have help distinguishing between common baby ailments and more serious emergencies that may require immediate attention. Includes a foreword by Dr. Michael Crocetti, Assistant Professor and Director of Clinical Pediatrics, Johns Hopkins Bayview Medical Center, and also an extended resource guide and parent’s dictionary.

    Great Product; Relatively Easy Installation

    I benefited greatly from comments others made about this product and how to install it, and I thought I'd add mine for any who are looking at getting this. My 11-year-old Liftmaster chain drive garage door opener stopped working and had the same worn out sprocket that so many have described, with the white snow shavings, etc. I too feared I'd have to spend $100s getting it fixed, then I found this great product on Amazon. I installed it last night, the whole process, including finding tools and adjusting the chain and door afterward, took me about 2.5 hours, but the actual removal and installation of the part took only about an hour. Garage door works great now, and is quieter than before.For the installation, I did what the reviewer before me did, which means I didn't remove all of the stuff the instructions said to remove.

    Works like a charm, but what a lot of work it is.......

    First, I wanted to offer compliments to other reviewers that described the symptoms of the gears being bad - the "snow", the stop-and-starts, the stop working altogether but can still hear the motor running - nailed it exactly. Very clear to me after reading those that this was exactly the product I needed. It is exactly what it says it is - an OEM Liftmaster gear replacement assembly. The directions that come with it are excellent - step-by-step, and it explains exactly what you need to do. The directions are the best part of this product - if they were not so well done, it would be impossible.No knock against the product, but installation was considerably more work than I expected. I had visions of undoing a couple of screws, popping out a gear, putting in the new ones, and being done - boy, I couldn't have been more wrong.

    Worked! Here are a few tips.

    This is one of those time consuming jobs with little annoying issues. Here are my tips so hopefully you can avoid the problems I had, making your job much faster than mine was. The sprocket on the top of my unit broke so I just had to replace the drive gear and shaft. No other parts were worn or damaged so I didn't bother with them. The annoying part is that you unscrew the screws on the shaft plate from the inside of the unit and there isn't alot of room for your hand motion. I used the smallest ratchet in my set. A couple things to be aware of during this step is that you can remove the back panel with the circuit board by unplugging the circuit board. It has a multi-pin plug that is very similar to computer drive plugs.

    With this kit and a little time, you can repair your garage door opener.

    I was faced with the decision to purchase a new garage door opener for about $230 or repair the existing opener from 1992 which lacks some of today's safety features. Since I don't use this garage door often and I don't have children, I opted to save some cash and do the repair myself. I have no previous experience of doing these types of garage door opener repairs, but as a do-it-yourselfer I figured it was worth the attempt.The kit came with detailed instructions which broke the process down into 5 main steps each with multiple individual tasks. The instructions were not exact for my opener, but were close enough to get the point. The steps start with removing the motor with the worm, removing the chain stem with the gear, replacing the worm, replacing the gear, and finally reassembling everything. Once the first two steps were completed I brought the parts inside to work on. I had the most trouble removing the tightly set pin to replace the gear. About two hours... 5/5 L. T.

    Not for the faint of heart....

    This was a lot of work, more than I had anticipated, despite the excellent reviews here, warning of the many nuts, plugs, and pins involved.The directions were so-so. I found that they were written very generically with the intent to apply to variations of the models. The diagrams could have been more clear...for example, I had trouble figuring out where the retainer clip and limit drive gear (2A) was. It's the white thing on the end of the sprocket assembly shaft. My advice is to take your time and move very slowly through the instructions, step by step. There were a few things that delayed me:* The sprocket assembly had to be lifted up through the hole in the chassis, and I only had 2 inches of clearance between the top of the opener and the ceiling of the garage. This meant that the opener had to come down a few inches. I suspended it with rope and bungees since taking it down completely would have meant un-bolting it from the chain axel, and I didn't... 5/5 Spumanti (Mountain View, CA United States) - See all my reviews This review is from: Chamberlain Garage Door Opener Gear Kit - Part #41A2817 (Misc.)

    My Genie garage door opener (potentially 15yrs old since I bought the home used) started making a horrible racket and wouldn't open or close, but didn't make any noise when I disconnected the carriage release from the screw drive. That pointed to a bad carriage. I was very happy to find this part on Amazon.Installation was very easy:1) pull the manual release cord on the carriage to disconnect it from the screw drive2) remove the cotter pin/bolt from the old carriage and the angle bar that is attached to the garage door (leave the bar attached to the door)3) remove single nut supporting the track at the front of the garage.4) supporting the track with 1 hand, gently push the track off to one side just a couple of inches to allow you to slide off the existing carriageNOTE: after you pull off the carriage, you'll probably notice that some/many/all of the teeth have broken off5) slide the new carriage on being careful about the orientation... 5/5 Qikstart (Chandler, AZ) - See all my reviews Amazon Verified Purchase(What's this?)

    0 5/5 BK - See all my reviews Amazon Verified Purchase(What's this?) This review is from: LiftMaster 41A2817 Replacement Gear Kit This gear kit is perfectly fine but the one warning I would give is about the drive gear. It was a hassle getting the old worn-out drive gear off the bearing. You may want to see if you can remove your old drive gear first before ordering this kit. If you can, great - this kit will be what you want.....if you think you can install the new gear on your existing bearing as well. If you can't or find it too difficult to spend the time and effort to do so, then you may want to order the 41C4220A Gear & Sprocket Assembly Kit with the drive gear already on a new bearing. As of the time of this writing, the other kit is only $8 or so more. 0 Help other customers find the most helpful reviews  Was this review helpful to you? , February 6, 2012
