We are doing a timing belt replacement on a Deutz D2011 in our JLG 660SJ boom lift. We are replacing it for PM so the unit came in running. We are using the factory manual to do the work. We are able to pin and lock the camshaft, when we move to pinning the crankshaft timing, its off. We would have to make an additional 1/8 turn as measured on the camshaft in order to pin the crankshaft. As seen in the attached photo. Are we missing something or did previous person in there have the timing off that far and it still ran?? We are tossing around the idea of just pinning the camshaft, cutting off the belt and advancing the crankshaft so we can pin it and installing new belt and tensioner from there. Are we on the right path or are we missing something?

Weve spun this thing over multiple times, if we pin the camshaft the crankshaft is NOT at the machined flat spot unless we advance the belt the additional 1/8 ish turns.
mksJunior Member#4 I have not worked on this particular. Foley engines has a write up, google search. Sounds fiddly to include having the crank in the wrong spot.

Click to expand... thank you for your response! Yes, we've read though the Foley writeup on doing this job. They want us to pin the camshaft, pull fuel injector and crank the engine over by hand to find TDC then pin the crank..... but how would we be able to crank the engine over if the camshaft is pinned??? It left me more confused than we already were with the suspected timing being off.
mekanikSenior Member#6 Are there two timing pin locations on the crankshaft? Left front and right rear?
mksJunior Member#7 Also from the foley info actually short 4 and 3/4 minute video if the center bolt in the crankshaft pulley is loosened it may create trouble. The write up is kinda vague. Would hope the factory would be better.
mksJunior Member#8 Skidsteer engines on YouTube has a 1011 video, timing belt may shed some light.

It confirms my suspicions that even though it came in running its likely its jumped time or improperly installed last time it was replaced. We will go with pinning the cam, cutting off the belt and resetting timing on the crank as well as removing pushrods for inspection.
whtailhunterNew Member#10 mekanik said: Are there two timing pin locations on the crankshaft? Left front and right rear? Click to expand... Yes and no, there is one timing pin used in the camshaft that is at the bellhousing area and the second pin is used in the crankshaft near the pulleys. The issue we see is the engine is out of time. Came in running with no complaints of lack of power.
whtailhunterNew Member#11 UPDATE: We finally got back to this unit. We are going to reset timing as if it had lost a belt. We pulled all the pushrods out for inspection and 4 out of 8 were bent.
