TheNeedForZ Posted February 18, 2006 Share Posted February 18, 2006 This concerns my L28ET engine that I bought several months ago. When I tore it apart and removed the con rod/piston assemblies, the rods binds in the pistons. They will move if I use some force, just not freely. Squirting some lubricant into the oil holes will help a little bit but they are still not free to move. I have a set of L26 rods/pistons assemblies that I bought by mistake(the seller thought they were L24 assemblies) The L26 rods rocks freely in their pistons. So...what could have happened to my L28ET? I've tore the engine apart, everything looks normal except the binding rods in the pisons. Any ideas?

technicalninja Posted February 18, 2006 Share Posted February 18, 2006 Varnish inside the pin bores in the piston. usually will show as a brown line on the exposed portion of the pin (underside of piston). Spray with B12, rock piston back and forth, more spray, more rocking, blow out with air, repeat.... Be carefull to not use much force as it is possible to scratch the pin bores if you have an extremely dirty set. Some times soaking pistons in a can of B9 Carb dip will help. The B9 is a much more dangerous chemical. You DON"T use air to blown it off pistons. Carefully wash the B9 off with water. Use GOOD rubber gloves. If you get either of these chemicals in your eyes your will never forget it. Good Luck Quote Link to comment Share on other sites More sharing options...
