Got a question for the experts on here. When my oil pump went out on my 230 d-152 and it partially spun the rod bearing I noticed a little smoke coming out of the dip stick which I expect but on the fuel lift pump side right above and towards the back end of the engine on the head was a round hole about maybe 1/4" or so that had smoke puffing out of it. What on earth is that hole? Is it where a small freeze plug or something went? I never noticed it until the puffs of smoke. And I can't seem to locate it in my IT manual.I'm going to tear the engine down just wanted to get all of my parts when I do and I don't know what if anything should be there. This is the first MF I've ever had only worked on Fords before this one. Thanks.

Hello Danny,
The only thing that I can think of that would be in that vicinity is the rear engine lifting bracket. The horizontal bracket is attached by 2 3/8" unf studs and nuts. Is this bracket in place? It is possible that the drilling for one of the studs has gone through possibly into the port of the number 3 exhaust valve but above the valve seating.....hence the puffs of smoke in time with the number 3 cylinder firing perhaps.

Hey David P. thanks for the reply. I'll look closer and see if it indeed has threads. Also if you had an engine that was rebuilt and sat for 15 years then after a few hundred hours the oil pump died and it partially spun the number 3 rod bearing but didn't mess up the journal to bad. Also never ran hot or smoked would you clean up the journal put in a new set of bearings and pump and change the oil an filter a few times or do a complete rebuild? About all it would cost is my time and a couple hundred dollars if I had to go back in. I value your advice a great deal and appreciate you help. By the way my last name is Welch according to my research maybe you are a distant cousin!

When rod bearing starts to spin in the rod, the rod end goes out of round. So if you just put another bearing in it, it may want to spin in the rod again. You can either get a new rod, or take the one have, and have them resize end (if the rod end didn't get too hot, change colors). On a resize rod the remove a few thousands od a inch off the rod cap, then bolt it back together, and bore the end round again.

Hi Danny, this is a 'piece of string' question. No two tractors in the same circumstances would be the same. In order for the shell bearing to turn it has to be gripping the crank journal by some degree. It will not turn of its own accord. All I can suggest on this one is to remove the sump and inspect each of the BE journals very closely for any marks or scoring and if possible measure the journal in a number of diameters and see if they meet spec allowing for the fact that you might already have oversize bearings. Std or the oversize size should be stamped on the back of the shell. If the diameters are all good and there are no major marks the journal can be cleaned with fine emery cloth tape. Keep as much dust as possible out of the oil passages and blow it through with a compressed air line as well.

I don't know the origin of the word 'Welch' but of course it has a downside in the English language. An example of this would be to 'welch on a deal' where one side would back out after a deal has been done. Not applicable, I'm sure.
