Number 1 cylinder will be the cylinder closest to the radiator. Ie; at the front.
Firing order is 1 5 3 6 2 4.
Not shure what you have dont there.


Well that is a kick in the nuts....

okay can someone tell me looking at the engine starting from the radiator back which cylinders are which.... The service manual states nothing. So basically I timed it to whatever cylinder looking from the right side of the engine second from the left... Oh boy I am going to be an expert on this dozer before I am done.... Back to the drawing board.....

Things are going nuts here it's starting to scare me? so lets change things to easy steps, if you are standing at the front of the bulldozer looking at the engine the crankshaft turns clockwise, No1 cylinder is closest to the Fan, the engine is a pig to turn without the turning tool but as already said the timing hole above the flywheel might be your best bet, stuff some rag in the hole and remove the timing pointer as this is easy to damage, the rag is to stop any bits falling in so remove the rag after the pointer is out, then turn the engine over via the flywheel it will be anti clock from this position and note the valve movement, it might pay you to mark the exhaust valves with Tippex or something to help,it's best done with both the valve covers removed off both heads to stop any error, study the valves when you see the inlet valve on the front cylinder closing you are on the compression stroke, so keep turning the flywheel anti clock until the TDC point comes up (the back cylinder valves will be rocking) you now have the engine on No1 TDC, remove your pump and reset following the service book. tctractors

Thank you for your step by step... I appreciate it... I will go ahead and pull the valve covers both off tomorrow... And will crank the starter and use the tippex pen... Sorry to scare you... Trust me it sucks more on this side....After looking at the first valve cover closest to the seat It seemed somewhat dry to me... This makes sense as it has been sitting for years... There are two oil fitting on the valve cover (1) each... Not sure why specifically there.. I will add some oil in the top so it is properly lubricated...

According to the service manual you loosen the 4 bolts on that come off of the flywheel that attaches to the injection pump... set the dowel to ip for the slot and find TDC -1 now I know it is closest to the radiator... Here we go back to the dozer tommorow... Thanks for hanging in there... I will get her done.....

The firing order, 1-5-3-6-2-4 is listed at the top of page 3A-10 in your service manual under Engine Specifications.
Injection pumps are numbered 1 to 6 starting at front of engine.
Undo what you have done and start over!!!!!!

. I hate to muddy the waters with to much information, BUT you were close. Second cylinder from the back is #5. With firing order 1,5,3,6,2,4,,, When # 5 intake JUST stops moving ( closes), the previous cylinder (#1) is at TDC and will have valve lash(loose rocker arms). It is an old Detroit tuners trick. Don't need to look for timing marks.

Hi,
before you go much further, how did you determine that No1 cyl. was the second cylinder from the front of the engine ?????

If it was by the position of the Injection Line from the first from the front Injection Pump going to No2 cylinder then it is likely that some of the injection lines have been incorrectly installed to the wrong cylinders.

I know that the D13000 and D342 have a mixed injection line sequence from the injection pumps to the injectors and so the Injection Pump body has cast on numbers to alert you to this fact.

I am not sure if the D353 has the same --only did a couple a really long time ago to not recall such now--can someone help out with regards this.

Cheers,
Eddie B.

Hi Eddie,

To be honest I went off the Crank looking through the flywheel indicator and I took off the first valve cover the back not the front and Set the TC 136 mark to the mark needle... (I believe the mark on the flywheel was stamped TC 136... I thought #5 was #1, I was wrong... I can tell you for sure that #5 cylinder both exhaust and intake are closed.... I am going back tomorrow to take both valve covers off and look at #1 cylinder... I have a feeling I have a 50-50% chance of being still in timed... The reason being is I know for a fact that I used the flywheel that stated TC 136 To set it and that means it could be correct but will verify with inspection... The injection pump and the lines where not crossed. I appreciate your thoughts and ideas... Thank you for taking time and sharing... Aloha....

Thank you for taking the time and reaching out... On the flywheel it states TC 136 and I lined that up with the needle... I will look at it tomorrow but I hate to assume it is at TDC if #5 intake and exhaust are fully closed then it would make sense that #1 cylinder is at TC especially since I aligned to that mark but just looked visually at the wrong cylinder. So would what they are calling backlash would that be loose rocker arms?
AGAIN THANK YOU
