Russ:I'm sure you can do it yourself, this operation is over-the-dealer-head, the dealer will only sell you the entire panel for the 1630. You can modify your existing panel using New Holland parts, therefore, protecting your warranty. My tractor is also new and the temperature gauge is a added feature. I can guide you through the operation and at a minimum you can have an electronic repair shop do some incidental soldering for you. The first thing you do is order the gauge and sending unit from New Holland.1) Temperature Gauge # 86540855 (approximately $38.00)2) Temperature Sending Sensor # SBA385720070 (for 1630 about $18.00)Make sure the dealer sells you the right sending sensor; on several occasionsNew Holland shipped the wrong part (these are not stock parts). Twice theyshipped the sensor for the 1725 do to mis-packaging. These parts for the mostpart have not been requested; I've discovered that there is mis-packaginguntil such time that the system is corrected. The sending unit is differentbetween the 25 and 30 series. the sending unit is located just below yourthermostat. If you have access to a 1630 examine the sending unit as comparedto the 1925 sending unit. Understanding the difference between the two willsave some time. The 1925's sending unit is a simple switch. It sends asignal to the instrument panel when the tractor reaches a temperature of 228degrees. This is at the absolute upper end of the tractor normal operatingrange. The 1630's sending unit is a variable resistor sending a constantsignal to the temperature gauge, with an operating range 100 to 221 degrees.Should you near 221 degrees you shut the tractor down and fix the problem. ....

Tommy:If you read this, you found the site. The answer to your question:Does the new temperature sending unit replace the original temperature switch located on the theromsat housing. YES, its that easy. Use no pipe thread putty or thread tape when installing. I'll be setting up a web site with numerous photos that will be of further help. Keep on the look out. Please note that the installion process above applies to all Boomer series tractors. ....

It is important to find, at a well supplied hoddy store, copper tubing 3/32 diameter, usually sold in lenghts of 12 inches.The gauge connetion requires 3 studs connectors (the gauge has 4 sockets on its back side, ONLY 3 SOCKETS ARE USED) Cut the tubing into 4 inch long pieces. Insert each stud into the gauge using the outter 3 sockets. Viewing the gauge on its back side with its pre-drilled set screw hole at the bottom to yorr left, the first socket to your right is the ground, the next socket at the bottom outside corner is the sending unit, the socket above the sending socket is the ignition. Let me stop here and await any questions or confirmation of the process thus far. Next time, I'll introduce instrument panel modification, gauge attachment and some minor soldering requirements. If any of you are at this point, that is parts in hand and the panel disconnected from the wire harness, you're 50%done. Please acknowledge this post. ....

Larry: YES you can do this. Should you need any part of the process re-explained, I'll be happy to help you. My 1725 is used very hard, its a loader, backhoe, grader and post hole digger and is used everyday, long hours. The maintenance on the machine is extraordinary, Oils and filters changed every 30 days including 60 day radiator flushes. I was never satisfied not having a temperature gauge, now that the panel has been fitted with one its one of the best things I've done. Its so easy to monitor the engine temperature. I know the tractor a lot better now, and I do take good care of it. Soon I'll be posting some photos. Please stay in touch. ....

It is important to note the temperature switch (located near the thermostat) that you will be removing is connected to the wire harness via a male prong. The new temperature sending unit is connected to the wire harness via a male blade connector. The wire connected to the new sending unit will have to be fitted with the proper connector. I'm sure you can find the female blade at an auto parts or auto electronic shop. My son (electronic student) made an male prong to female blade adaptor that allowed me to keep my original wire connector. I don't think it matters, cut the old connector off and install a high quality, well insulated female blade connector. Remember to use a little dab of silicone into the new connector to wire socket before you crimp it in place. ....

Thanks for the additional info on installing the temperature gauge. I ordered the parts yesterday from the New Holland dealer in Beaumont, Tx. He is going to ship the parts directly to my residence. He said they would be here in a few days. I'll get back with you then! Thanks for all the help! Tommy ....

Tommy:Have you removed the two set screws securing the instument panel to the tractor and have you disconnected the panel from the wire harness? If so, you will now need to do some bench work; this must be a dust-free environment. The tractor will be down for the next few days, if this is a problem, just schedle the next proceedure until such time that the tractor can be idle a few days. These next installation step must not be rushed.Please advise me if you have all the aforementioned parts. In addition you'll need a 12 inch lengh of 22 AWG copper stranded insulated wire (light weight automobile electrical wire) and a soldering iron with a small chisel point, some rosin core solder and a small tube of silicone sealer. Do you have or know someone with general low volt electronic knowledge?At the rear side of the panel remove the small philip screws to separate the lens and gray plastic gauge trim from the main panel housing. Carefully, slide out the gas gauge from the panel (place in a sandwich type plastic bag) Notice the three post connectors. The objective is to install three like post for the temperature gauge. I will explain how this is done once you confirm you have all the tools and parts. Please advise....................You can immediately remove the blank plate in the gray panel trim for the temperature gauge. I used a zip router to establish a rough opening (excerise caution; the trim is ABS plastic, strong but it will crack. This is not a part you can order) you can drill several one inch holes, next start to nibble away at the surrounding plastic using a pair of wire cutters (I have a pair wire cutters that have wide cutting edges that are perpendicular to the handles, like a little jaws, excellant for nibbling away at the plastic. Sorry, I don't know the tool name). Nibble the plastic to as close as you can to the finish edge and file to finish, I used a convex wood file (1 side flat the other side rounded), rat tail file and a emmery fingernail file for the final pass, It finished like a factory cut. I promise, we'll finish up soon. ....

The 3/32 inch copper tubing will friction fit into the temperature gauge. Measure the female fitting depth of one of the gauge sockets; measure the depth of the plastic off-sets on the white electronic tray (the back side of the gauge is positioned onto the off-sets). The objective is to cut the tubing to a length that will penetrate the gauge sockets at the three (3) elctronic points, i.e., ignition, ground & sending unit, then pass through the off-sets and pass through the circuit board and to extend at least 1/16 of an inch beyond the circuit card.There are two (2) critical steps that must be done with the utmost care. 1st, you must identify the abovementioned gauge electronic connection points. The connection points must be then identified on the circuit board, now the circuit card must be de-soldered, this is done by heating the solder glob for about 3 seconds on the backside of the circuit board (the circuit card must be face down and remain contained within the white plastic electronic tray, when I did this operation I removed the gas gauge, remove the set screw holding the gas gauge to the plastic tray, followed by using a small screw driver inserted to push the back side of the gas gauge outward. You'll notice that the post the gas gauge mounts to serve to power the gauge and to hold it in place). After the solder is molten, gantle lift and tap the electronic card/tray downward striking flat against you work bench/table. This force will cause the molten solder to dislodge from the circuit board. Do this to the three (3) board to the copper tube to the gauge points. Insert the copper tubes into the gauge, make sure there is a tight friction fit, mount the gauge onto the tray whereby the copper tubes pass through the tray's off-sets and through the circuit board and the tubes extending slightly beyond the board. Solder the tubes the the circuit board (careful not to over heat) The tubing connects the gauge to the board and also serve as mounting post. Do not try to remove the gauge form the tubing post, Install a set screw at the gauge to the tray. Dab a glob of silicone at the back of the gauge to the tray, this is an extra measure to secure the gauge. The next critical operation is to jump the number 5 pin and the 15 pin located on the board where the wire harness connects. This is another careful solding job. The wire size as previously specified. I will be posting a diagram of where the number 5 and 15 pins as located for those of you who do not have the New holland part manual. Please acknowledge this post! ....

With the electronic tray (white plastic gauge holder) flat on your work bench, (black foam down) you will be soldering a jumper conductor connecting # 5 post, which is the 25 series temperature indicator circuit and jump it to the #15 post, which is the 30 series temperaure sending circuit. Notice that the wire harness plugs into the pin bundle socket, which is at the back side of the instrument panel. The jumping will occur on the rear of the pin bundle. Again, you will solder the jumper at the back side of the harness plug. The foam side down. Notice that the back of the harness plug has small post exposed through the circuit card. Think of the layout as rows and columns, notice 4 rows and 6 columns. Working left to right, the top row is 21, 17, 13, 9, 5 & 1. Pin 1 is at the upper right hand corner, the right hand column (or column #6) is as follows: 1, 2, 3, & 4. Column #5 is 5, 6, 7 & 8. Column #4 is 9, 10, 11, & 12. Column 3 is 13, 14, 15 & 16. Solder a jumper between #1 and #15. The process is complete. I used a dab of silicone over the jumper to protect it from all the likely vibrations. As you reassemble the instrument panel use a small bead of silicone to re-establish the gasket bond as needed. Once the panel is installed it will take the tractor at least 15 minutes before the gauge will show signs of movement. The thermostat must open before the gauge detects an increase in temperature. Please advise me as to your end results and/or do not hesitate to post any questions. NEW PROJECT- are you ready to install an oil pressure gauge, please advise. Anyone doing future post please let me know what is your home state. ....

I completed the installation of the temperature guage! There were a couple of problems... The primary one is that the temperature sending unit has bolt threads and not tapered pipe threads. I checked the part number and was sent the correct part. The temperature sensor screws all the way in to the shoulder and to make it seal I had to make a gasket out of soldier at the shoulder of the sending unit. Also, my origional temperature light begins to glow as the engine warms and gets brighter as the engine gets hotter (getting more ground as the temperature increases). THis is ok with me, and I don't consider it a problem or I would remove the bulb. THought you may want to know about these two issues. Overall, I'm very happy with the installation.

TommyIt is important that you remove the bulb at the indicator light. The bulb could burn out your new temperature sending unit; the bulb will draw to much current from the temperature sending unit. This could also cause a false reading at your new temperature gauge. ....
