| I'm sure it depends on the specific engine, but in my experience with an 1104 I had to place a quarter inch spacer under the #1 intake valve rocker and roll the engine over by hand until the piston contacted the valve. Using a cam wheel I made note of the angle and rolled the engine over the other direction until it contacted the valve again. By using the middle value of the two crank positions found, I had TDC. This was following a procedure from the factory service manual, no less. |

Mid-Missouri | How familier are you with the 1104. I have an 1104C-E44T in a Gehl 7810 skidsteer and looking for the strongest starter available. Here is what I came up with but it cost over $400. It looks like it is meant for the bigger brother 1106. Do you think it would fit? http://www.iskra-ae.com/eng/docs/new_applications_march_2008.pdf Page 17-19, 17 in particular. |

NM | I just did my perkins in my NH Telehandler. On it you have to remove the front gear cover and the marks are on the cam and pump drive gears.

| Not overly familiar. I just have an engine we received for near scrap prices due to a spun cam bearing. We replaced the cam bearing and got the engine running, but haven't attempted to do anything to it. |

|
| To illustrate for Krantz... I took this picture when I did the cam bearing on our engine. I used a sharpie to highlight the timing mark so I could see them easier. From the factory they are laser etched and can be a bit tough to spot.

Boonville, IN | What is the age of the engine or the model number of the equipment that the engine is in. On the older Perkins engines ( up to mid eighties, early 90's) the injection pumps were dummy splined. The three bolts that hold the injection pump on are in slots. There is usually a mark on the base of the pump that the injection pump rebuilder puts on showing the timing and you will find a scribed mark on the block to line it up with. The newer perkins are different than this to time. |

| That way it is on my Massey Ferguson 275 tractor with a 248 Perkins engine in it. I did what you describe when remove the injector pump to have it rebuilt a few years ago and line up the marks on the pump and the camshaft housing. |
