IDENTIFICATION: The retainer rings do not have a part number on them. Identification must be made by their cross section width. See the illustration. The new 8N7295 Retainer in the relaxed position has a cross section width of 4.70 0.20 mm (.185 .008"). Both the former 83214 and 8N8058 Retainers have a width of 4.32 .18 mm (.170 .007").
The pistons in these engines can be checked to see if they are usable according to the procedure that follows.
If the groove in the piston is visibly worn, a new piston must be installed.
If the groove in the piston does not show any visible wear, install new retainers and check their fit. Check the amount of force needed to turn the new retainer in the used piston. A comparison of this force with that needed for a new retainer in a new piston can be made. If the force needed for the used piston is much less, a new piston must be installed.
