V-BELT SET 5L3308 - Caterpillar

This procedure alleviates the need for the "H" bar to hold down liners during projection measurements.
Liner Projection Components
(1) Bolt. (2) Washer. (3) Washer. Install clean liners or cylinder packs (without the filler band or the rubber seals), spacer plate gasket and clean spacer plate. Install bolts and washers, as indicated previously, in the holes. Install all bolts or the six bolts around the liner. Tighten the bolts to a torque of 95 N m (70 lb ft).Use the 8T0455 Liner Projection Tool Group to measure liner projection at positions indicated with an A, B, C and D. Record measurements for each cylinder. Add the four readings for each cylinder and divide by four to find the average. If the liner projections are out of specification, try rotating the liner or install the liner in another bore to see if the measurements improve.If the liner projections are all below the specifications or low in the range, 0.025 mm (0.0010 in) or 0.051 mm (0.0020 in), try using a thinner spacer plate. These plates are 0.076 mm (0.0030 in) thinner than the regular plate and they will increase the liner projection, thus increasing the fire ring crush. Use these spacer plates to compensate for low liner projections that are less than 0.076 mm (0.0030 in) or if the inspection of the top deck reveals no measurable damage directly under the liner flanges, but the average liner projection is less than 0.076 mm (0.0030 in).Do not exceed the maximum liner projection of 0.152 mm (0.0060 in). Excessive liner projection will contribute to liner flange cracking.With the proper liner projection, mark the liners in the proper position and set them aside.When the engine is ready for final assembly, the O-ring seals, cylinder block and upper filler band must be lubricated before installation. Apply clean engine oil immediately before assembly. If applied too early, the seals may swell and be pinched under the liners during installation.
