Who Can Rebush Conrods?
« on: September 08, 2009, 04:58:05 AM »
Can anybody recommend somebody, either is Australia or the USA, who can rebush conrods? I have an old OS 29 twin stack and two old Super Tigres (51 & 40) that are worn in the big end.

There was a company called "RPM" (or R.P.M.) that manufactured bushed con rods for our engines. Mebee a search will turn up something...

I would worry that when worn out, the supporting structure might also be compromised (e.g. worn too). So there may be a strength issue.

You might try Mattes Engine Rework.  This is a site I happened across but have no experience with their work.  If they can help you out, please post result here.

Dallas

Most anyone who has a small lathe can make a bushing for you, Get SAE 660 bronze, or Phosphor bronze or use a automotive bronze valve guide, You may need to buy a reamer or 2 sized near what you are working on.

I suggest that you talk to Herb Hanna, (Dallas Hanna) or John Goodwin (raglafart) on the forums.

Cheers, Geoff

The first name that comes to mind is Bill Gruby, Master Machinist.

He just had surgery, but should be recovering soon.  We all hope.

 Thanx Clancy;

  You make me blush.
  They can be rebushed without too much trouble. The problem comes if they are worn out to one spot on their circumferance. If this has happened I have to agree with Allen, their strength has been compromised. In that case the lesser of two evils is to make a new rod. Randy is correct 660 Bronze is the stuff to use.
 A good drill press and a dedicated jig and anyone can bush a rod, it is not rocket science. A lathe is better and a mill better yet.
 My preferance would be a new rod, don't mess with the old ones.
