Hello, I have several machines (and Land Rovers) with these dpa pumps., I find them to be very reliable and I like them because they are easy to strip and service with no special equipment. The only problems that I have had has been diesel leaking out of the governor cover at the throttle and stop lever spindles, just a couple of O rings and an easy job. Of course, where diesel leaks out air leaks in which can cause starting problems but an easy fix. As for which is better, the short answer is, I don't know. Regards, Jon

Good day from Ont. My 574 has not got that on. A neighbor told me about that on David Brown, he said if they don't work diesel will run in cyl. Thanks

If anything fails it can cause problems. Instant failure on those thermostart integral valves doesn't usually occur. If it has the small reservoir there is usually only a small amount of diesel in it..... If it has been in there 40 years maybe a new one might allay fears?

How do I test the thermostart wiring with a volt meter? It’s on a Perkins 3 cylinder AD3.152 diesel engine that’s in my Massey Ferguson 231 tractor. I don’t think the thermostart is working.

You need an ammeter the thermostart should draw about twenty amps. A multimeter will not do the job, they normally fuse at ten amps. Or take the plug out and see if it is working, see my video 'Genuine thermostart v. spurious. Good luck, Jon

@@wotjonsez2560 Is there anyway to test, with a volt meter, if the single black wire that plugs into the thermostart is getting power when I turn the ignition switch to the heat position?

@@travisricks3436 Yes, if it's a negative earth put the black lead to ground anywhere on the chassis or the neg. battery terminal and the red lead on the thermostert terminal try the switch and you should see battery voltage - 12-13 volts. If it's a pos. earth put the leads the other way round. You don't even need a meter, with the switch on just try the wire to the chassis and you should get a spark.

@@wotjonsez2560 I had a mechanic test 2 thermostart plugs using lead wires off of a 12V battery. Both were bad! 1 wouldn’t heat up at all, and 1 wasn’t getting power at the terminal. I’m going back with a genuine OEM Perkins thermostart, part number 2666108. This is for a Massey Ferguson 231 tractor with the 3 cylinder Perkins AD3.152 diesel. Very happy that I now know what the problem is! Just gotta order the thermostart now. Thank You!
