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

[@cal48koho]

very well done explanation. The engine is a real beauty!

[@p.melvinshyturtle3722]

I pulled the plastic pin out, made a facetime call between my ipad and iphone, put my iphone down where i could watch the timing indicator show up while i turned thE motor.

[@LightWaIker]

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

Good common sense explanation. Thanks!!

[@HollywoodCod]

Very informative video. Thanks. I’m a mechanic and this helped me a lot! About to put a Cummins swapped ford on the dyno, going to advance the pump.

[@clark7111]

Extremely helpful! Thanks!

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

[@HenryCastronuovo]

Very nice, clearly helpful thank you sir i will attempt this on my own.

[@JackConnick]

I just used an inspection mirror and a flashlight to see the de-dent.

[@cdpperformance2613]

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..

[@dante04srt]

Glad to hear it helped you out.

Nice name lol

[@mitchelltownsend4119]

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?

[@deanjohnson2183]

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

[@robc3863]

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

[@shanepeterson8679]

Excellent info. Very helpful tips. Thanks 👍

[@rogelioespinoza7852]

Well done, thank you, thank you, thank you. Clear and concise

[@ken808surf]

360 degrees to adjust other valves. not 180

[@kennethryan8112]

Yea i might as well just pull the head off the engine and put it at tdc that way

[@stuartbagedonow9770]

I’m a mechanic for over 45 years., I feel your pain. Thanks

[@garekpurcell4786]

Very helpful! Thank you😃

[@kknows3512]

You keep saying 180 degrees when you mean 360 degrees. Still a good video though.

[@dante04srt]

You're right. Too much time working on gas engines in the past and the terminology just stuck.

[@jacobecavalier1499]

How do I time the pump ?

[@vendetta1306]

God bless

[@blainecelestaine4543]

Thx

[@jeremiahvotruba2921]

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]

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]

@@dante04srt truck is not stock. I will not be able to pin the pump. Will I lose my timing that has proven to work well?

[@dante04srt]

@@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.

[@jeremiahvotruba2921]

@@dante04srt uhhhhh that's not good. Very much appreciated responses! Thank you sir. Have a fantastic day.

[@shartlesrestorations2263]

How did you retrieve the broken piece of timing pin inside the injection pump?

[@dante04srt]

I was able to find it through the governor spring access. It took a while and I had to get creative to fish it out. It wasn't fun.

[@shartlesrestorations2263]

Thank you . I don’t want to have this pump torn down . Ugh

[@88theduke88]

Where did you find a metal pump timing pin?

[@dante04srt]

Picked it up from a seller on Amazon if I remember correctly.

[@oldcroneysgarage9739]

How did the swap go?

[@dante04srt]

Swap went good. Got it running in my 98 K3500 dually cclb. Sooooo much better than the 454.

[@oldcroneysgarage9739]

@@dante04srt I bet it gets better fuel mileage too

[@dante04srt]

@@oldcroneysgarage9739 MUCH better. I haven't done any MPG figuring yet as I'm still getting things dialed in but based on the fuel gauge alone, I am seeing significantly better mileage.

[@dante04srt]

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.
