KDP killer dowel pin fix
« on: August 12, 2010, 06:18:43 pm »
here is what we are tryin to stop


here is a rough sketch of what to build



Blocking Tab Installation Instructions:

Timing Cover Removal         

1.   Remove fan assembly with a 36mm or 1 7/16" wrench. The thread is left hand and you may need to whack the wrench with a hammer to break the nut loose. In many cases, a drift punch and hammer are are the easiest tools to use for breaking the nut loose; place the punch on the driver side of the fan nut face and hit the punch with a hammer.

2.   Remove the fan belt. (3/8" ratchet)

3.   Remove the 6 bolts that hold the fan pulley on and then the 4 that hold the fan mount to the block.

4.   Remove oil fill tube and adapter. (13 mm wrench)

5.   Remove vibration damper. (15 mm wrench)

6.   Remove the bolts that hold the gear cover to the gear housing. (10 mm wrench)

7.   Gently pry the cover away from the housing, taking care not to mar the gasket surfaces.

8.   Clean the old gasket residue from the back of the gear cover and front of the gear housing.

Tab Installation

1.   Remove the timing gear housing bolt closest to the KDP. (10 mm wrench)

2.   Position the tab so that it covers the dowel pin hole and is wedged between the cover bolt boss and the rib cast into the housing.

3.  Install the original bolt through the tab and torque to 18 ft-lbs. (10 mm wrench) Use Locktite 205 or similar on the bolt threads to prevent the bolt from loosening. While you are there, remove the other bolts ONE AT A TIME and apply Loctite and torque back to 18 ft-lbs.

Timing Cover Installation

1.   Lubricate the front gear train with clean engine oil.

NOTE: Mike Beatty reused the seal and gasket with no leaks. Use a thin plastic, like what is on a loose leaf binder, and tape it together to make a tapered sleeve. Just be very careful installing the crank seal over the snout. Oil the snout and sleeve with synthetic oil, and it will slide right on.  It also helps to use several studs to guide the plate on and hold it until you get the other bolts started. If you do it this way, you can skip to step 10.

2.   Use a hammer and punch to drive the old seal out of the cover.

3.   Thoroughly clean the front seal area of the crankshaft. The seal lip and the sealing surface on the crankshaft must be free from all oil residue to prevent seal leaks. The seal is designed to transfer a film of teflon to the dry, clean crank surface after initial startup

4.   Apply a bead of Loctite 277, or equivalent to the outside diameter of the seal. (Note: Some use 242 blue or 205 Red)

5.   Install the seal into the rear of the cover using a plastic hammer and the alignment/installation tool provided in the seal kit. To prevent damage to the seal carrier, hit the alignment/installation tool alternately at the 12, 3, 6 and 9 o'clock positions.

6.   Install the pilot from the seal kit onto the crankshaft.

7.   Using the pilot as an alignment tool, install the cover and a new gasket.

8.   Install the cover bolts and tighten to 24 Nm (18 ft. lbs.) torque. (10 mm wrench)

9.   Remove pilot tool.

10. Install the oil fill tube and mounting bolts. Tighten the bolts to 43 NM (32 ft. lbs.). (13 mm wrench)

11. Slide the small black plastic dust seal (included in the seal kit) over the end of the crank and up snugly against the crank seal with the flat side out. Install the vibration damper. DO NOT tighten the bolts to the correct torque value at this time.

12. Install the fan mount to the block and the 6 bolts that hold the fan pulley on.

13. Raise the belt tensioner to install the belt. (3/8" ratchet)

14. Tighten the vibration damper bolts to 125 NM (92 ft. lbs.). (15 mm wrench) Use an engine barring tool to keep the engine from rotating during tightening operation.

15. Install the fan assembly. 36mm or 1 7/16" wrench

Dowel Pin Stabilization Instructions From Cummins:
The dowel pin itself can be replaced if desired or Locktite can be used to hold it in place, without having to replace the pin or gear housing assembly. Inspection and securing of the timing cover dowel pin:

1.   Remove the damper, pulley and gear cover from front of engine.

2.   Tap on the dowel pin with a flat punch to insure that it is seated in the bore.

3.   Clean all the oil from area with solvent and dry completely.

4.   Apply some wicking type Locktite #290 on the dowel pin and let the Locktite cure.

5.   Reinstall the cover with a new seal and gasket.

6.   Reinstall damper and pulley.
95 12v 4x4 auto K&N drop in. 4 inch turbo back MBRP exhaust, Garmon trans, 4k gsk, 140 injectors, fully modded afc, pump timed, delivery valves, custom ground fuel plate, Phatshaft 62. And a very large list of to do's.
