Hi

I have mahle piston for my 5.3 engine I want to use my stock connacting rod but my stock connacting rod Fit press pin and the mahle had floating pin is what must I do ??

 

Get a floating pin connecting rod?

Why you would want to reuse the stock ones is beyond me. Even a basic OEM Gen IV rod is cheap enough to swap in.

 

I have floating pin with my new Pistons , I want to change my old Pistons with new mahle Pistons

 

If your rods are press fit and the pistons are floating pin, then they'll work together just fine. Take them to a machine shop to assemble.

 

I take is to machine shop he doesn't know what he will do he asked my what do you want me to do

 

 

Ok but the new piston had floating pin it's ok if I press it ?? I will not have any problem in future??

 

Nope, it'll be fine.

 

Depends on what size the pins are.

 

Thought I remembered reading that pressed are .943" and float are .944"
If true, a competent machine shop could still hone the rod small ends to get the correct interference fit.
A few other options are as someone suggested, get a factory full floating rod
or just hone the small ends enough to float them metal on metal. I've run engines like that on the street plenty of times. We used to just drill a small oiling hole into the end of the rod (top inward toward the pin hole) and with .0008" clearance they would often look just fine on repeated teardowns.

 

I don't understand why you would put in aftermarket pistons with stock rods.

Ask questions FIRST before committing to poor choices.

What will it cost to recondition stock rods and hone them for the different pin size? Then you still have stock rods.........

 

Because I have the Pistons for free I don't want waste more money I will use it as stock piston

 

Thanks gays I asked mahle thay say


You can use it as Press-Fit or Floating

Wrist Pin Size: .945" same the stock size
