Honeywell802360JA Motor

Had no issue installing it and the device worked with no issue.

easy to install

worked perfectly and easy to install

This motor was not an exact match for my M874D1004 unit. The differing speed is not a issue. However, the pinion gear was approximately .080" longer than the original motor. The gear at this length did not permit a full return to the home position due to internal interference. I was able to shorten the length by grinding the end down until it matched the original. This modification worked and was necessary to obtain proper functionality.

A zone valve motor is for a home heating zone.

This is a very reasonable repair. If you're very careful and methodical it will take 20 minutes. It's an entirely dry process. Although it's a good idea, you really don't even have to shut off the water. You don't have to sweat pipes. You do have to shut off the electricity. It's two screws and four wire nuts.I purchased a second motor to keep as a spare for the next time I lose a zone valve. My system has 6 zone valves. Over the course of 10 years I've had to replace three of the original motors in my system. If you have multiple zone valves in your system It's worth keeping a spare on hand. In my system these motors are by far the most common point of failure.

This worked perfectly. I have a boiler radiant heat system. Every now and then the zones go out. It's a huge frustration and expensive part of owning a system like this. Having the knowledge that I now can fix these zone valves with these 26.00 motors is a huge relief. Thanks to amazon and honeywell for selling these motors. As many have said plumbers or HVAC guys will charge us a ton of money. This is an easy fix too. Unscrew the tiny screw, remove wires then put new one on screw it back in then reattach the 2 wires. You will be done in 5 minutes. I'll buy more of these as back ups. I m very happy. If your zone keeps allowing heat to flow through its likely the motor is shot. Buy one of these replace it quick and back and running you will be.

NOTE/UPDATE 12-12-2016Here's MORE BAD NEWS:Since my last comment, three (3) more of the four (4) motors that I bought in this order and held in my parts inventory have failed in as little as nine (9) months since installation BUT six (6) months of actual use since these are used in my home heating system; and not used in summer months. THE SHAFTS THAT HOLD THE GEARS SHEARED OFF ON ALL OF THESE. These are the ones with the small diameter shafts that I discussed earlier in this review. I've only ever had a large shaft break and it did that within hours of installation. That one appeared to be defective heat-treating = too hard. I've used a lot of these motors in the past 20 years since they have a high mortality rate in the field.I'm attaching two (2) more photos of the shaft diameter difference between the large shaft and these that failed with the small diameter shafts. It also shows the broken units. The usual failure mode is jammed gears inside the motor. These with the small shafts don't even get that far.Unfortunately, I have not been able to get through to anyone at Honeywell, the manufacturer. I've also never got a response from the seller.NOTE / UPDATE 03-12-2016:Here's a follow-up: I just installed one of these motors on March 3, 2016 and the output shaft sheared off just 8 days later. The shaft looks like it was improperly heat-treated causing it to break. I had this happen on another one of these motors a few years back. See the photo attached. The usual failure mode is that the gears in the motor mechanism lock up. I also installed 3 of the other motors from my order of 4; 1 a year ago and 2 as recently as last month. I'll update this review as appropriate. The bodies of all of my valves operate with little effort, so I don't think that the motors are being over-stressed.I have a high failure rate application for these ,motors. They are used on White-Rodgers 13A02 zone valves. The inner gear-trains fail by locking-up and the motor needs to be changed.The four (4) Honeywell "Synchron" motors that I received look suspicious in quality. The motor's out-put shafts that the brass output gear is pressed onto is too short. It only protrudes into the gear less than half the gear's length. This is unlike the dozen or so failed motors that I have collected over the past 20 years. All of them have shafts that extend through the length of the gears. Having the correct length shaft is critical, as the gears is loaded heavily at its end, where these gears are not now supported by the shaft. The gear also depends on the press-fit friction between it and the shaft in order to transfer the rotation. Without full engagement through the gears length, the gears ability to drive is diminished significantly.Since I am putting these new motors into my spare parts inventory, I will not know if they are satisfactory until I put them into service. I am attempting to contact the manufacturer, Honeywell, to see if this is an issue to them, but I have not yet been able to complete that.For whatever it's worth, these motors are marked "Made in the USA, Packaged in Canada". I have other motors (that have the correct length shafts) marked as being packaged in the USA, Canada and Hungary(?).I will remain skeptical that these motors will deliver the service that I need given this newly observed factor. I am considering returning them for credit.

I use this motor to replace the motor (640 24V 60CYC 5W 6 RPM 35335l-5-6 8510) in the Honeywell MD847A-1031 furnace damper, it works great and a perfect fit. I'm satisfied with it.

Works perfectly. My heat works again.

Excellent value, very easy to install after viewing some online videos. Saved a lot of money compared to plumber who replaced the entire metal box assembly with brass water fitting, switch, gears/springs, motor. Tip: clean off any old dried out grease that's stuck on mechanical lever teeth that mesh to new motor gear

This Zone Valve Motor was the closest match (appearance & specifications) to the one I was replacing, which had been in use for over 25 years. It costs a little more than the less expensive alternatives, however I chose not to cheap out and purchased this (what they claim is a) 'Honeywell' OEM Replacement part. So far so good, very easy to install (one screw & two wires) works like a charm and the motor is virtually silent.
