help with Thermo dyne

[Paul1890]

Hi

I need some help. I cant seem to find anything on internet or from mack

I have a 70 U model, with a thermodyne,at least that is what valve cover says.

Purchased truck in 83, we did an in frame overhaul on engine in 2004. All parts available from Mack then

Was running perfectly, but it knocked out a wrist pin bushing, about 25,000 miles since in-frame.

It has a 1-5/8" wrist pin, I don't seem to be able to find these wrist pins or bushings. Mack is no go and PAI also does not show them.

I'm a little confused , i thought all Mack turbocharged  diesels had 2" pins. Wondered if these parts were still available. This engine does not have wrist pin oil nozzle coolers.

Any help would be greatly appreciated. The motor is perfect except for wrist pins, hate to change if we don't have to

Thanks again
