EMPI 0.36mm Flywheel Shim for VW Air-Cooled Engines

EMPI 98-1281-B is a 0.36mm (about 0.014 inch) flywheel shim that sets crankshaft end play on 1966-and-later 1300cc to 1600cc air-cooled VW engines, matching VW part 113 105 289A. Three shims sit between the crankshaft and the flywheel, and their combined thickness decides how far the crank can slide fore and aft. The target is about 0.07–0.13mm (0.003–0.005 inch), which protects the main bearings from premature wear. Sold individually so you can mix sizes.

EMPI makes six thicknesses, 0.24, 0.30, 0.32, 0.34, 0.36, and 0.38mm. The 0.36mm shim often lands in a stack beside 0.34mm shims (two 0.34mm plus one 0.36mm total 1.04mm). Order one size above and below your calculated stack so a final check that comes out slightly off doesn't hold up the build.

Fitment & Compatibility

EMPI fits this shim to Type 1 engines from 1966–1979, the Karmann Ghia from 1967–1974, the Type 2 Bus from 1964–1971, and the Type 3 from 1964–1973. Go by the engine, since many of these cars no longer carry the one they were built with.

Installation & Tuning Notes

Measure end play at the flywheel with a dial indicator or EMPI's 5760 end-play tool, and convert to millimeters (inches x 25.4). Subtract the clearance you want to finish with. The result is the total your three shims need to reach.

Common Questions

How many flywheel shims does my engine need?
Three, in whatever mix of sizes brings end play into about 0.07–0.13mm.

Can I reuse my old shims?
Only if they are flat and free of burrs. A bent shim throws off the measurement.
