Connecting rod bushing needs work

[2wrench]

This connecting rod top has a hole that should
line up with the hole in the bushing, but they are off
a bit. I suppose I have to drill the hole through for good
oil passage, huh?
Excuse the pic quality, please.

This is the connecting rod bushing that attaches to the
piston.

I hate to take the time to return it to the machine shop
for this. I think I can do it myself, but will listen
to voices of experience on this issue.

Use a very sharp drill and go slow. You just don't want to have a convex shape going toward the pin. I guess the oil is coming from the crank and up the rod to spray on the inside bottom of the piston to cool it. Did that piston look like it had been heated more than the others? Just curious.

Just some BS, I had my bushings check when I put new pistons in the TR6 and all the bushings were just fine eventhough they had 80k+ miles on them. The bushes must be the best part on a TR6.

 

[2wrench]

Yeah. I figured the material is rather soft on the
bushing, so that's why I thought I could do it myself.

If it were mine, I'd likely leave 'em as-is as long as none of 'em were any more off than that one. It's a "splash" lube point not pressurized. Whatever oil gets tossed up there will get thru the hole you have. IF you decide to drill 'em, you risk having to check/resize/ream the bush I.D. If the pins are a proper fit now, no worries.

Just MY opinion.

Muck it up and you will be going back to get a new one put in. Leave it as is and it will get the exact same amount of oil anyway.

Send them back and make them do it right. Thats what you paid for RIGHT?

Either leave them alone or take them back to the machinist that you paid to do the job correctly.

2W,

If you paid to have this done, get it corrected now. There is no excuse for a shop not installing them correctly and it shouldn't be e big deal for them to correct the problem.

 

[PeterK]

Trouble is that the bushing is first pressed in and then reamed to fit the wristpins. So to replace it, the shop will need another bushing, most likely. They may just drill it out which would be OK but let <span style="text-decoration: underline">them</span> do it.

 

[Brosky]

Agreed, Peter.

Man, nice shoes...

Its like some kind of Cinema Verite...

With the line of the concrete going exactly through the middle of the opening in your hand and the tapering lighting on the "mystery" cord on the right...

Definately counterpoints the surrealism of the underlying metaphor.



As to the holes in your con-rod not being aligned:

I agree with the above agreeing.

AMC,

Those are really Dale's feet and shoes.

They manage to show up in nearly every thread with pics.

 

[amcboy]

WOW! And I thought he was just being "arty" in a pedestrian post about connecting rods or something.

DUDE :smirk:
