Re: Loose Rod

Guys: Look at his post above. He states he is using AER (Antique Engine Rebuilding) rods. If these rods and inserts were purchased within the last 8 years, the inserts are not tri-metal. They consist of a steel shell with bearing grade aluminum applied. The aluminum is quite thick when compared to the last layer of a typical tri-metal bearing. The rod bolt spec for torque on an AER rod is 35#. I recall from his earlier post that he was torquing to 45#. (50# in one case.) If he is torquing to 45#, he could be twisting the cap and binding the bearing... "More" is not "better" when torquing to a manufacturer's spec. I have used lots of the rods and inserts from AER and they have all been consistent in sizing. ("Lots" equals over 180 sets...that's over 720 rods and insert shells) Given he changed a loose rod to a different journal and it corrected the problem...either his method of assembly has changed or the diameter of the rod journals vary. Or am I missing something here? I still suspect the rod journal diameter is not consistent. Follow-up: I just saw his follow-up posted while I was typing this. He had the rod caps interchanged. Problem solved. Good! But...I still suspect the rod journal diameter is not consistent. Good Day! Last edited by Dave in MN; 04-02-2020 at 12:41 PM. |

Re: Loose Rod
See, it is good that we kept nagging at you. Now you can have a good time touring the countryside. I'll bet you never do that again.

Re: Loose Rod
Bravo!
Honest mistake, but something to ponder, as technology changes so does the discipline. Put it together and enjoy, J

Re: Loose Rod
This just didn't add up, something was wrong. Its nice the problem was found, but, the rods and caps should have been marked.

They are. Each rod has a unique number within a set of 4. The rod and cap are each stamped with the same number on one side. Keeping the numbers directly aligning on the cap and rod is how you know which way to install the cap on the rod. (and, in this case, which cap goes with which rod.) Good Day!

Re: Loose Rod
Same here! Honest mistakes are OKAY as long as you recognize them.

Re: Loose Rod
Mistakes are just a part of learning. If any mechanic ever tells you they've never made one then he's pulling your leg. In your case you caught it before it got out of hand so that's a good thing and will make you feel a lot more confident. It makes a person careful to check things completely before changing tactics that might do more damage than good.
I've found that the guys who admit mistakes quickly and move on are much less likely to make mistakes in the future. It's a sign of good character and something a few of folks I've know over the years could use more of. |
