Hy,



I'm rebuilding my enigne and it's now near completion. I used new housings and irons, but have several used irons as spares.



I noticed that my new rear iron did not come with the brass/meesing water outlet plug (beneath the oil pedestrial and thermostat)

I tried removing one from a used iron but htat's near impossible.





Next? i checked my parts catalog (the PDF file on the net) but didn't find this part as aseparate item.



Does anyone know a good trick to get this plug out of a used iron or know the part number for a new plug?



My irons are N3F series.

If you have a screwed up iron, just heat the **** out of it(the iron).

AFAIK the water stud is glued in.

Hy kim,



Thanks fr the info.



Do you happen to know the MAzda part number for it? Otherwise I just order a new one.



Thx

I don't think there is a number for those. I've tried to find them myself. I got one out by heating the iron and turning the outlet with a pair of vise grips. Turns it to break it loose then wiggle it out. If you have a totally trashed iron the easiest way might be to score each side of the iron with a cutoff wheel and then give it some good whacks with a hammer. Cast iron is brittle enough it should break pretty easily. Wear safety goggles.

damn... other option is to tap thread in it and convert it to a An line or some aftermarket plug with thread.



Problem is that the engine is together and steel chips might get in the water system. Though I could turn the engine on the engine stand with the hole facing down and thread it like that, and just going in and out eveyr couple of mm to get the steel chips out.

that part of the iron is really weak, we had a couple mazda remans that got tipped, and that just snaps right off
