What RonM said the tangs go the same side. On a 53 block the number marked side of the cap faces the same side of the block that has the serial number.

Cheers

i used to be a industrial engine rebuilder and i do not recall any bearing tabs going to opposite sides wether rods or mains they allways go on the same side. if you are still in doubt put the cap on with the tabs on the same side and torque you should not be able to feel a step in the bore. 90% of the time if the bearing caps are put on rong they will bind up but not allways. hope this helps

Somewhere I have seen an engine that had the tabs opposite, but can't remember what it was...I don't know how people get that idea, I once got a call from a young guy who had done an in-frame on a 3020 JD-he said it would barely start, then die...he thought he had it out of time...I went to turn the flywheel to find the marks, & almost bent a big scrrewdriver. The thing would barely turn over...Upon examination, he had the main caps on bacwards...he said every engine he had ever done had the tangs opposite...
Those bearings were really shiny on one side, but hadn't grabbed yet...
Hopefully beantown will check back here before he puts her together.

Every time we make any statement as to how things should be some one will find an exception! That said most that I've seen have the tangs on the same side. I did find a set of replacement inserts for a V6 Chrysler that didn't have any tangs at all! The supplier stated that the little tangs were not needed, the crush when torqued down was sufficient. I had to go back to Chrysler to get inserts with the proper tangs. This is why notes need to be made when disassembling. But I've seen motors put together wrong and been run that way so always pay attention to these little details on reassembly or you may be duplicating someone else's mistakes. TimM has good advice above and should help if in doubt. F.J.W.

A lot of the newer engines don't have bearing tangs anymore. I worked for an engine machining plant ~6 years ago and they were removing the bearing tangs from their conrod lines, as it was an "unnecessary" machining step. Apparently the crush fit actually keeps the inserts from spinning.

Yes that may work with every thing fresh and new, but once things get a bit worn those inserts can rotate if the tangs are absent. The big reason for MFGs are leaving them off is that it saves a machine step and they can save a few cents, also if the thing fails after a few years they can sell another. F.J.W.

The 6.7 Ford Powerstroke does not use tangs anymore.

Hi, I had a couple questions for the DD sages.I've been told that JD used DDs in some of their machines. I acquired a JD 1010C Diesel 4 cyl a while ago cheaply,and was considering upgrading it to a DD if one could be found,had on the cheap. Question is are all DDs 2-53 same bolt pattern as the orphan JD 4 cyl diesels ? Could a 2-71 bolt in as well ?

Thanks,
Pete

.There should be stamped on the bottom of the block pan rail a number one. This number is the side the bearing cap numbers would be installed. Bearing tangs in the saddle and cap are on the same side. AL

The 1010 transmission & rear end is the same as a 435D, which used the 2-53, but the clutch housing is not. A 435 engine will not bolt up to a 1010. I'm not sure if the flywheel housing used on the 435 is proprietary to that application or not, it is a Detroit part number. 2-53's are scarce, & most will have the SAE bellhousing, i suspect. The starter mounts backwards on the 435, not on the 1010.
Don't even think about a 2-71, if it would fit the 1010 ring gear & pinion couldn't stand it...the 2-53 wiped out most of the original rear ends, they were the same as a 430 gas. My 435 has a 1010 R&P in it, plus the final drive gears have had teeth welded back on.
Just noticed you said 1010C, the crawler with a 2-53 was the 440ICD, same applies as to bolt-up. Not too many of them were built...but they were cool...
