You have to pull the flywheel off of the crankshaft to see the woodruff key. The key should point up towards the camshaft. there are two marks on the plastic camshaft gear that also must align with the two marks on the housing.

Model 31G777 Need to know what the timing position is for this engine please ,As stated earlier I have it at 3 o clock it wont start . ideas please

Don't waht your trying to with the 3 o'clock position but crank and cam timing marks align with each other.

Instructions from service manual:

Install Crankshaft and Camshaft

1. Lubricate the cylinder bearing/oil seal with engine oil.

2. Install intake and exhaust valve tappets.

3. Support both ends of the crankshaft, and carefully install into the cylinder.
NOTE: The counterbalance system, if equipped, must be assembled to the crankshaft before installing into the cylinder.

4. Assemble connecting rod assembly to crankshaft.

5. Install the timing gear to the crankshaft with timing mark out. The flange of the gear must face the counterweight link, if equipped.

6. Install camshaft, making sure tappets clear cam lobes. Timing marks (A, Figures 6, 7, 8) must align.

7. On horizontal crankshaft engines, make sure the paddle on the governor shaft (B, Figure 6) is rotated in line with the governor cup inside the crankcase cover.

8. On vertical crankshaft engines, assemble governor gear/oil slinger (B, Figures 7 and 8) to camshaft. Make sure the paddle on
the governor shaft is contacting the governor cup (C).

2000 honda odyssey v6 I need the timing mark on

The cams are very distinctly marked, and numbered for the cylinders, with a cast mark in the aluminum cover behind the cam marked for alignment. The crank gear has a dimple, and the keyway should be up, to line up with the v mark on the oil pump behind it.

I need a manual for model 842252441 craftsman rear mount tiller. I bought a new engine for my tiller and am having a problem with exchanging the new for the old specifically the crankshaft.

I was looking at various manuals available for craftsman tow-behind tillers.If you click this link you'll find 7 models of craftsman tow-behind tillers listed. While I didn't find your exact model, one or more of these manuals might be useful.

Also, I noticed that on the 486.252442 manual, it mentioned contacting Sears has rebranded many company's products as Craftsman over the years. I suspect in this case, Sears repackaged a Agri Fab 71-252441 as the 842252441. I found a few web sites selling a paper manual for the 71-252441, but I didn't find anywhere to download an electronic copy.

Agri-Fab's website is and their contact page lists a toll free contact number (800) 448-9282. Their web site had manuals for 6 tow-behind tillers, but none of the models obviously matches up. You may be able to look at them and ID your model better than I. You could also try giving them a call maybe someone can ID their model number for your tiller.

Hope this helped. If so, please give it a thumbs up!

How to set tne timing on a7.5 hp ohv engine

For the Camshaft Timing:

The gear on the camshaft usually has a dot between two of the teeth and the crankshaft gear normally will have a hash-mark on one tooth. Align these marks and the camshaft timing is set.

For Ignition timing:

Set the Ignition coil at .010" clearance from the flywheel magnet and ignition timing is set

Hope this helps,

Connecting rod bolt torque and cam to crank timing on a 16.5 ohv model#310707 type#0137-E1 rider mower engine

moz-screenshot.jpgmoz-screenshot-1.jpgRod bolt torque is 150 INCH POUNDS - - NOTE: INCH POUNDS NOT FOOT POUNDS

Valve timing is generally performed by matching either a dot or dash mark on the cam gear with a dash or dot on the crankshaft gear. If your engine has a ball bearing, the mark would be located on the crankshaft counter-balance. It is important that the marks match, EXACTLY. One mark will be on the top of a tooth on the gear, the corresponding mark will be found on the bottom of a tooth on the other gear.

Need specs.for Honda rototiller motor

The valve clearance is 0.08 for intake valve and 0.11 for exhaust valve . To do the timing you have to remove the spark plug and set the piston at top dead center (all the way up) and on the cam pulley you have a mark (like a triangle) that you have to align with the fan cover bolt hole . Hope this help
