    TR4 piston question

    Reply Quote

    I purchased a 86 mm piston and liner set from Moss.P/N  814-310

    The eng is back together and running great.

    Now I notice in the TR4 shop manual (pg.1-102 fig.36)   that the original pistons had a slot in the skirt that must be orientated toward the offset on the piston rod bearing cap or, facing the cam shaft side of the engine. 

    Someone please  tell me that the Moss pistons don't have a slot on the piston skirt like the originals!

    I can't for the life of me remember if they did. If they do,what happens if they are installed 180 out? 

    I can't sleep at night!!!!!!

    Dear KSD.

    You can rest easy. The new pistons are based on an updated design and do not have a slotted skirt.

     

    Enjoy your TR.
