SECT5.FR5 Page 20 Tuesday, March 21, 2006 12:49 PM Inspection Assembly Refer to Figure 5-19. Two methods can be used to assemble camshaft gears on a camshaft. 1. Thoroughly clean camshaft (3). Use the heat method to install new gears on a new camshaft. Use the press method if reusing any service parts. Do not use heat method on used parts. Use magnaflux (PT7190) inspection procedure to detect cracks. HEAT METHOD — CAMSHAFT/INJECTION PUMP DRIVING GEAR INSTALLATION 2. Inspect camshaft lobes and journals for evidence of cracks, pitting, scoring or severe wear. If any of these conditions exist, replace camshaft. Refer to Figure 5-19. 3.
Inspect camshaft gear (1), injection pump driving gear (5), and camshaft captured thrust washer (2) for cracks, pitting, scoring or adverse wear. 1. Thoroughly clean camshaft (3) and gears (1 and 5) using a contact-type cleaner that dries rapidly and leaves no residue. 2. Insert key (4) into camshaft (3). It may be necessary to tap key with a rubber mallet to ensure proper seating of key. 4. Visually inspect key (4) for signs of distortion or breakage. 3. Install a new camshaft captured thrust washer (2) on camshaft. 1 5 2 3 4 200310a Figure 5-19 — Camshaft Assembly Components Page 5-20 200 BENCH PROCEDURES 1. Camshaft gear 2.
