12 Valve Cummins Diesel Engine Timing Pin Quick Tip

12 Valve Cummins Diesel Engine Timing Pin Quick Tip - Finding TDC The Easy Way

Рет қаралды 50,961

Күн бұрын

In this video I demonstrate some of the tips I learned while working on my 12 Valve. After a bit of trial and error, I was able to find TDC using the timing pin. In the video I show how to keep from snapping it and I show a quick way to find TDC easily and quickly in the future without needing the timing pin.
Although there are many ways to go about this process, as a newbie I had to learn some mistakes along the way. This is by now means the best way, or the only way; I wanted a way I could easily see a few key items on the engine and determine if the #1 cylinder was at TDC, or how far off it might be. This method also helps to confirm if the timing pin is seated or not and can also help show visually if your pump gear has slipped.

Thank you. Actually very helpful. That ending was good too. I appreciate you passing the knowledge and probably saved me from doing the same.

Power driven diesel on KZfaq has another way of adjusting valves on the 12 valve. Good luck with your build.

Hi Dante. Could you advise which intake and exhaust valves to adjust at tdc and at 180 from tdc? 180 is at the crankshaft or camshaft? Thanks

Anyone know how to find TDC on a vt555? It's installed in a boat, and the damper is too corroded to see the mark

@mitchelltownsend4119 Жыл бұрын

So I am lookin at a 1st gen cummins with a new injection pump and the pump or the engine is out of timing. If I did exactly what was in this video could I find TDC without taking anything off?

Help me a lot understanding when I went to ajust my valves after head gasket repair had other people saying after I get pin to slid in the d-tent hole and set valves on #1 and it’s companions is rotate over 360 and put pin back in and do again but it’s not there your right. You would have to spin balancer twice just to get it to see hole in timing gear were pin goes..

So.... engine is at TDC. P100 is still in truck. Does that mean the pump is TDC? This is where I sit at the moment. Any guidance?

@dante04srt 2 жыл бұрын

The pump is always going to be a bit advanced in relation to engine TDC. When engine is at TDC have you verified if the pump can be pinned using the included pin tool? If the engine is at stock timing (listed on the engine serial plate), the pump should be able to be pinned when engine is at TDC.

@@jeremiahvotruba2921 I'd say unless you have a degree wheel or some way to measure as you turn from TDC to where the pump pin lines up, you'll not have a good reference to where it is now.

Now that I've got about 14,000 miles on the swap now, I've been able to get some good mileage data. At about 65mph, I'm getting about 18mpg. Loaded with our camper (~8k fully loaded) I'm seeing 13.5+. Bear in mind I still have 4.10 gears so there is still more to gain if I regeared. All in all, I'm very happy with the swap. It makes the truck so much more capable and fun to drive.
