connecting rod sleeves?

Post by Farm Shop » Wed Dec 10, 2014 4:09 pm

The small ends of my connecting rods have just enough play in them with a new wrist pin installed that something needs to be done.

I have read posts about Honda having made oversize wrist pins but I was wondering if anyone has successfully bored and sleeved the small end of the rod to accept a standard pin again?

Not a lot of metal for sleevng the rod. Oversized sleeves are available still.

Mod code -305

I see that David Silver has them available here in the states. I was just curious if anyone has attempted sleeving the rods.

And with the wiseco pistons I decided to go with the Honda pins would need to be shortened.......

Thanks for the reply G man I will keep the post updated when my machine shop let's me know what they can do!

Soooo..... The machine shop said it wouldn't be a problem to shorten the Honda wrist pins to fit the wiseco pistons and bore the pistons for the oversize pins.

But they won't bore the rods. I know I've seen posts about people doing it with a straight flute reamer?? Does anyone have any input on how difficult it would be to do that way myself?[/list]

The problem is getting the reamer to run perpendicular to the rod. Ideally you would dismantle the crank and ream the rods on a vertical miller.

Making a tool that used one rod as a guide for the the other might work.

I have some rods to do and I was thinking of making a tool using a scrap cylinder barrel as a guide.

I've not worked out the detail yet.....
