Pistons, Piston Rings, Connecting Rods & Cylinders Disassembly & Assembly: Assembly

WARNING: This page is about a different car, the 2004 Suzuki Grand Vitara. However, it is still accessible from the selected car via links, so may be relevant.

Two sizes of piston are available as standard size spare part so as to ensure proper piston-to-cylinder clearance. When installing a standard size piston, make sure to match piston with cylinder as follows.
1. Each piston has stamped number (1 or 2) on its piston head. It represents outer diameter of piston.
2. There are also stamped numbers of 1 and 2 on the cylinder block as shown in the figure.
3. Stamped number on piston and cylinder block must correspond. That is, install number "2" stamped piston to cylinder which is stamped also number "2" and a number "1" piston to cylinder with number "1".
A letter "A" or "B" is stamped on piston head but ordinarily it is not necessary to distinguish each piston by this letter.

Piston-to-cylinder clearance

Piston-to-cylinder clearance: 0.02 - 0.04 mm (0.0008 - 0.0016 in.)

Install piston pin to piston and connecting rod:
After applying engine oil to piston pin and piston pin holes in piston (1) and connecting rod (3), fit connecting rod to piston as shown in the figure and insert piston pin to piston and connecting rod, and install piston pin circlips.

NOTE: "86F" mark on connecting rod must face toward crankshaft pulley side.

NOTE:
- Install circlip with its cut part facing as shown in the figure.
- Install so that circlip end gap comes within such range as indicated by arrow "A".

Install piston rings to piston:
- As shown in the figure, 1st (1) and 2nd rings (2) have "RN" or "R" mark respectively. When installing these piston rings to piston, direct marked side of each ring toward top of piston.
- 1st rings differs from 2nd ring in thickness, shape and color of surface contacting cylinder wall. Distinguish 1st ring from 2nd ring by referring to the figure.
- When installing oil ring (3), install spacer first and then 2 rails.

After installing three rings (1st, 2nd and oil rings), distribute their end gaps as shown in the figure.
