This article mainly introduces Perkins 2806F EngineTurbocharger-Install
NOTICE Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened component life.
1. Ensure all the components of the turbocharger are free from wear, damage, and restriction. Replace any component that is worn, damaged, or not free from restriction.
llustra6on 5390d0rr8502. Ifnecessary, follow Step 2.a through Step 2. fto install tube assembly(8) and tube assembly(15).a. Install a new O-ing seal(23)(not shown) to the elbow connection for tube assembly(8). Ensure that the O-ring seal is correctly seated into the recess of the elbow connection.
b. Install tube assembly (8) and hand tighten tube nut(24). Install bolts(20)(not shown) hand tight. Ensure that O-ring seal (23)(not shown) is not dislodged as the tube assembly is installed.c. Install a new O-fing seal(22)(not shown) to the elbow connection for tube assembly (15).
Ensure that the O-ring seal is correctly seated into the recess if the elbow connection.
d. Install tube assembly(15). Install bolts(21) and hand tighten.
e. Tightening of bolts(21), bolt (20)(not shown), and tube nut(24) will be required after the turbocharger has been installed.
f. For a turbocharger that is already installed, tighten bols (21), bolt(20)(not shown), and tube nut(24) as follows: Tighten bols (21) to a torque of47 N-m
(35 lbft).
Tighten bolt (20)(not shown) to a torque of
47N·m (35 ib ft).
Tighten tube nut (24) to a torque of65N-m
(48 lbft).

3. If necessary, follow Step 3.a through Step 3.b to install studs (19) to exhaust manifold (16).
a. Apply Tooling (A) to the threads of new studs
(19).
b. install studs(19) to exhaust manifold(16).
Ensure that the studs are correctly orientated.
Tighten the studs to a torque of 18N-m
(159lb in).
4. Attach a suitable lifting device to turbocharger(7).
The weight of the turbocharger is approximately
30kg (66Ib).
5. Install a new gasket(17)(not shown) onto the exhaust manifold. Ensure that the gasketis correctly orientated.
6. Use the lifting device to position turbocharger(7)
onto exhaust manifold(16).
7. Install nuts(18) to turbocharger(7) hand tight.
8. Install a new gasket(13)(not shown) between tube assembly(15) and turbocharger(7).
9. Install Allen head bolts(14) to tube assembly(15)
hand tight.
10. Install a new gasket(10)(not shown) to tube assembly (8). Install Alen head bolts (9) to the tube assembly hand tight.
11. Tighten nuts(18) to a torque of 55 N-m(41 b ft).
12. Tighten Allen head bolts(14) to a torque of
25N-m(221lbin).
13. Tighten Alen head bolts (9) to a torque of25N-m
(221lbin).
14. Iftube assembly (8) and tube assembly(15) had been removed, follow Step through Step to tightenbolts (21), bolt(20)(not shown), and tube nut(24).
a. Tighten bolts (21) to a torque of 47 N-m
(35 lb ft).
b. Tighten bolt (20)(not shown) to a torque of
47Nm(35lb f).
c. Tighten tube nut(24) to a torque of65Nm
(48 b ft)
15. Connect inlet hose(6) to the inlet of turbocharger
(7). Refer to Disassembly and Assembly, Air Cleaner Housing-Remove and Install for the correct procedure.
16. Install a new O-ring seal(2)(not shown). Position elbow connection (3) onto turbocharger (7). Install V-band damp(1). Ensure that the O-ring seal is not dislodged as the elbow and V-band clamp are installed.
17. Follow Step 17.a through Step 17.b to tightenV-
band clamp(1).
a. Tighten V-band clamp(1) on the turbocharger to a torque of 8.5N-m (75 ib in).
b. Lightly tap V-band clamp(1) with a soft faced hammer to seat the V-band clamp. Again, tighten the V-band clamp to a torque of 8.5N-m
(75 b in). Repeat this Step 17.b until the V-band clamp are correctly seated onto the turbocharger.
18. Install a new V-band clamp(4) and connect exhaust connection(5) to turbocharger (7).F ollow Step 18.a through Step 18.b to tighten the V-band clamp.
a. Tighten V-band clamp(4) on the turbocharger to a torque of 8.5N-m (75 lb in).
Note: Ensure that the flexible exhaust section is not strained and the flexible exhaust remains in original alignment.
b. Lightly tap V-band clamp(4) with a soft faced hammer to seat the V-band clamp. Again, tighten the V-band clamp to a torque of9N-m
(80lb in). Repeat this Step 18.b until the V-band clamp are correctly seated onto the
14. If tube assembly(8) and tube assembly(15) had been removed, follow Step through Step to tightenbolts(21), bolt (20)(not shown), and tube nut(24).
a. Tighten bolts(21) to a torque of 47N-m
(35 Ib ft).
b. Tighten bolt(20)(not shown) to a torque of
47N·m(35 Ib ft).
c. Tighten tube nut(24) to a torque of65N-m
(48Ib ft).
