MCC Posted January 29 Share Posted January 29 I have recently acquired a 656D. The glow plugs all ohm out the same, but I was wondering if their performance can degrade with time even if they electrically read fine. I believe I saw a post on here where someone said there are better glow plugs available today that heat up much faster. I'd consider replacing them if they get weak with age or there is something better. Thanks, Dan Quote Link to comment Share on other sites More sharing options...
Injpumped Posted January 29 Share Posted January 29 if they work, they work. The older ones took almost a minute to warm up. Modern ones take 15 seconds. Some guys rethread the powerstroke gp, but I normally just sell the correct ones. The newer ones are made by diesel rx and don't like more than 12 volts, so if you have an alternator capable of charging 14.7V, it's not a good idea to glow after it starts to help clean it up. That will smoke the newer ones. Good luck! 1 1 Quote Link to comment Share on other sites More sharing options...
kevinj Posted January 30 Share Posted January 30 Keep in mind that the old original genny never put out what a modern alternator does. So if ya still have a genny it may be fine. I have a modern alt on mine and can burn up glow plugs!! After it starts.....no more glow to clean it up. Best to let it die out & start over. 1 Quote Link to comment Share on other sites More sharing options...
Missouri Mule Posted January 31 Share Posted January 31 Diesel rx in my 656 here. Going on 5 years. Have yet to burn one out knock on wood. Hold it 5-10 seconds and she fires right up. If it's real cold I'll let off for 5 seconds and hit it another 10 but normally dont need to. When its 80 out I hated sitting there 30 seconds. Seemed like an hour when I'm trying to rake hay or whatever im doing. The only reason I tried it is because I modified the plug not the head, so what was I out? Only thing I dont like is they seat right at the end of threads so theres potential to get one stuck in there if it doesnt seat on the shoulder of plug I suppose soot could get up in there around the threads. So theres some caution 1 Quote Link to comment Share on other sites More sharing options...
560Dennis Posted January 31 Share Posted January 31 Hers what my experiments . I find that the when I testing old GE will glow red in 15 seconds . I tested three separately,all I have in tool box . That surprised me . But I did not consider I was testing one with alligator clips and 18 guage wire off the 12 volt battery directly . The best test would all six as close to real service conditions , what the time to get them all red is a much better test , I have not tried this . I think but was testing the diesel doc plugs three or four years ago , I say they were slightly faster to glow red , but I can’t recall the time and it was a single glow plug test. I did not have good luck with diesel doc plugs , burnt them up in a month using the ihc starting procedure for 560 . Tips expand had the tractor down with injectors out to drill out Diesel doc plugs they expanded that much . If I could get them I would get more used GE OEM plugs . Personal preference they have stood the test of time. Just me. I have not had good luck with cheaper eBay plugs either . My locals dealer gave me this tip that use to start my 560. Whirl the engine 2 to three turns before you energize the glow plugs . That wets the glow plugs with fuel and you get a much better vaporizing of fuel for starting and it prevents the cheap glows plugs from overheating. Then energized the glow plugs for 10 seconds and starter to whirl the engine , it’s should start about 15 to 20 seconds. What I do today with cheap glow plugs ,they last longer . Again what I’ve found ,do not have the resources to test reliable to say this fact ,but still works so far on a 560 . 1 Quote Link to comment Share on other sites More sharing options...

acem Posted February 3 Share Posted February 3 I installed a Ford style starter relay on my 706 25 years ago. Quote Link to comment Share on other sites More sharing options...
886 dreaming Posted February 4 Share Posted February 4 Last year put in a set of DRX 00017 glow plugs,started tractor one time.2nd time will not start all six plugs burned out. old plugs put back in 5 out 6 good plugs tractor starts. I also use a relay. This winter down to 3 good plugs and a bad block heater. DRX plugs for the 282 are not cheap thought a controller would help.The new drx plugs have not been used yet. I am using 6 of the cheaper amazon plugs have 2 spares, I like how the trator starts so far working good. Replaced the block heater 600 watt a&i brand claims usa made. Bad rite out of the box Quote Link to comment Share on other sites More sharing options...
Injpumped Posted February 4 Share Posted February 4 Only time I've had anyone smoke the DRX plugs right away is if they had a battery charger on and glowed for 30 seconds like the old ones. Important to know they are now fast glow plugs, that only need power applied for 15 seconds. Maybe you got a bad batch, who knows. Quote Link to comment Share on other sites More sharing options...
