I know this has been discussed before, but, does any one know what company was the last to make the M&W Power seal engine kit was? Seems i remember they quit making them? Sure would like to find a set for a 8070. Thanks Randy ------------- CA WD WD45 D17 D17 Diesel 7060 8050 8070 |

| You may not be able to deal with them directly. I believe that they have been purchased by Howard Enterprises of Indiana. |

What? Who do you order from, and what have you been getting? I had no idea you guys dealt in parts like this! ------------- There isn't much a WC can't do. WD's just do it better. |

I did some checking today, Hershel Adams told me that the plant where they got M&W power Seal kits did burn down and all molds were lost, had hoped that was not the case, now am checking with Toms Agri Diesel. Thanks for all the help. Randy ------------- CA WD WD45 D17 D17 Diesel 7060 8050 8070 |

Gee, I guess this means when I tear down my WD45 engine - the pistons go off to a custom maker. They were Pow'R Seal, and were a measured 8.2:1 compression. ------------- There isn't much a WC can't do. WD's just do it better. |

I put a set of Power Seal M&W knock offs in my 45 and they were 6.5 C/R instead of 7.25 like the real M&W's I replaced.I don't remember(been a while)but it seems like they were listed as WD45/D17 replacement.Maybe yours were for 175?They did NOT advertise C/R.I did a crude CC of bowls and the new ones held abut 10cc's more.Rough math indicated the stock 45 C/R on the new stuff.You call tell the difference on a hard load. |

I bought mine in '93 at the Louisville Farm Show. The guys were in a small booth that had signs to the effect "M&W Add-Power". The boxes said "Pow'R Seal". It was mostly Farmall stuff. I asked about M&W parts for Allis' at the time and I believe they said they had been "bought" by another company and were selling as much of the old inventory stuff as they could at Louisville and other farm shows. I asked about a '45 sleeve piston kit - and the one I have is the last one they had then, cost me $290. The guy brought the box out from under a table, and the other attendant remarked that some other guy (can't remember the name) "was going to kill you for selling those!". I can understand why, I reckon these pistons had the extra compression point yours didn't. I didn't put them in an engine till '2000 or so. They've been run hard for many hours and need a revisit. Never had a problem with them, stoutest farming WD I've ever sat on. ------------- There isn't much a WC can't do. WD's just do it better. |
