1. Raise and support rear of vehicle. Remove rear wheel assemblies. If drums are installed on vehicle,
remove cover from adjusting hole at bottom of brake backing plate. Turn adjusting screw with a brake
adjusting tool until shoes drag against brake drum and lock drum.
2. When shoes are against drum, loosen adjusting screw an additional 10-12 notches so drum rotates freely.
If drum does not rotate freely, remove wheel and drum and vacuum dust and dirt from linings. Use
sandpaper and remove rust from points where shoes touch backing plate. Apply a light coating of
molybdenum grease to brake shoe-to-backing plate contact points. Install wheel and drum and adjust
shoes.
3. To adjust brakes with rear drums removed, first clean all rust and dirt on points where shoes touch
backing plate and apply a small amount of molybdenum grease to those areas. Using a brake shoe
adjustment gauge, measure inside diameter of drum braking surface.
4. Reverse tool and adjust brake shoes until they touch gauge. Gauge contact points on shoes must be
parallel to vehicle with center line through center of axle. Hold automatic adjusting lever out of
engagement while rotating adjusting screw to prevent burring screw slots. Ensure adjusting screw rotates
freely.

Fitting Pistons
1. Ensure pistons are not scored or damaged. Measure piston diameter on piston skirt at 90-degree angle
from piston pin, .65" (16.5 mm) below lowest ring groove. See PISTONS, PINS & RINGS
under
ENGINE SPECIFICATIONS.
2. Check piston-to-cylinder wall clearance in 3 different vertical places of piston travel. If clearance is not
within specification, re-bore cylinders to fit oversize pistons. Using NEW piston rings, measure piston
ring side clearance around entire piston circumference. If clearance is not within specification, replace
piston. See PISTONS, PINS & RINGS
.
Piston Rings
1. If ring end gap and side clearance are not within specification, replace piston and/or rings as necessary.
See PISTONS, PINS & RINGS
under ENGINE SPECIFICATIONS.
2. Install oil ring spacer. Ensure ends DO NOT overlap. See Fig. 19
. Upper and lower rails are the same
and are interchangeable. In stall rails, ensuring rails are expanded by spacer tangs (oil rings when
assembled should rotate freely). Install rings No. 1 (top) and No. 2 (second) with "R" mark toward top of
piston. Ensure ring end gaps are properly positioned around piston. See Fig. 20
.
Fig. 19: Identifying Oil Rings
NOTE: Pistons and rings are available in .010" (.25 mm) and .020" (.50 mm) oversize.
