I need to find some 30 thou undersize bigend bearings for my D4 7J with the D4400 engine, original part numbers are 5B3762 and 5B3761, I have a old D4 parts number book here and someone has hand written the number 2F2360 alongside those 2 part numbers, so I'm wondering is 2F2360 a good number for the 2 shells that make that bearing, can someone please clarify that.

One of our nicer Catheads here in Oz has a new set of Miba conrod bearings he picked up somewhere, but he doesn't know what engine they fit or what size they are, the numbers on the box are   1466 05 0 ST    and 9F8580/ST     Can anyone please advise what these bearings suit, I'm assuming the ST might mean standard size, I just looked on Google and the 2014 Miba catalog I found didn't list any bearings for the early D4 / D4400 engine unfortunately.
Thankyou
Mike

Thanks Bruce, I sent them a message via the Machinery Trader website a week ago and never got a reply, that website shows Florin Tractor supposedly have one in stock too, I really need to confirm if that one part number has replaced the 2 original numbers.
All the best

OK, thankyou for that info Bruce, you didn't come across a description of the 2F2360 bearing by any chance did you, I don't want to buy a set out of the USA only to find they are not correct.
All the best

Well I found out this morning the 100 undersize 2F2360 bearings that American Crane supposedly have on the shelf is a fabrication, they don't have even one, nor do Florin, nor do Phil Hunt here in Oz, so I'm stuck.

I just tried a Google search for Federal Mogul for those undersize bearings for the D4400 engine, but got everything but old Cat engines.

Does anyone have a alternate part number, or numbers from aftermarket suppliers for 30 thou undersize bigend conrod bearings for the D4400 engine, engine number is D4 7J1276.
Thanks for your help
Mike

Mike, could you consider getting your shells retinned if you can't find new stock?

Yes Neil, in fact just this morning I spoke to a very clever guy here in Melbourne about possibly doing this, he said it will cost around $US150 per bearing, but the crankshaft needs to be in good condition. My crankshaft has old water stain damage unfortunately, and I'd really love to avoid having to dismantle the engine to clean up the crankshaft, it's already been ground to 30 thou under, this tractor will be lucky to do 5 hours a year.

It's a interesting problem Neil, when the engine oil is cold the oil pressure is a steady 34 pounds, both when slowly cranking the main over with the pilot motor, and when the diesel fires up, but within 20 minutes of starting the diesel, and the engine oil slowly warming up, I can see the oil pressure slowly decreasing on the guage, at high idle it's still 10-15 pounds, but at low idle it's only around 1-5 pounds, that's too low for my comfort.

I'm running 40W oil in the motor, and had the pressure relief valve screwed in as far as it will go, I dismantled the oil pump a week ago and it looks great, I can see how someone has been in there before and reconditioned it. I measured the conrod bearings on 2 cylinders with plastigage and got 13-14 thou wear, so they are at maximum wear, hence I thought if I could find some new bigend bearings I should help improve that low pressure at low idle.

I'm just confused at how I've got a beautiful 34 pounds when cranking the diesel motor over with the pilot motor when the oil is cold, then almost zero pressure when the oil is warm, unless the diesel is running above low idle. There is some minor wear on the oil pressure relief spring from rubbing within it's bore, and I'm aiming to replace that.
Thanks for your input, appreciate it
Mike

I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
