I just kept the fuel shut-off pulled and bumped it with the starter. No biggie. The valve just has to be off the lobe of the cam...

Turns out that American Diesel has an adapter that bolts to the pulley and provides a big hex head.

Hello All,
As a newbie to the forum and recent owner (last 4 years) of a Defever 44 I am wanting to make an attempt to adjust my Ford Lehman 135 valves myself. It has been a couple of years ago since I "observed" my Mechanic doing the job and it "appeared" pretty straight forward.
I have attended Bob Smith's diesel engine class several years ago and while I took copious notes on how to complete this job, I unfortunately, have forgot most of what Bob taught. (a mind is a terrible thing to waste)
There are references to "Da Book" in this thread, but I am not sure what you are referring too. Does American Diesel have such a resource manual? If not, where can I get one? Are there any links to "youtube" or other type of medias to help educate oneself in this area?
Wanting to learn, and thank you for your help,
Rusty

Greetings,
Welcome aboard. Da Book is usually the service manual. I'm sure theer is one available for your 135. We've got 120's, so no use what-so-ever.

Thanks,
I will make a call on Monday to Brian at American Diesel and see if he can provide one.
Travel safe,
Rusty

There's an error on page A28 in the manual under 6 Cylinder engines, Valves to Adjust. The third sequence, with Valves Fully Open, 2 and 6, the book says to adjust valves 7 and 1. That is incorrect. You want to adjust valves 7 and 11. You will notice the opening and closing sequence as you go through the valve adjustment. It's a head scratcher the first time.

On straight six four strokes, there is an easy way to set valve lash: Roll engine so #6 exh is starting to close and intake is starting to open (valve rock). At this point both int and exh should be at (or near)zero lash. #6 piston is now at or very near tdc, but not firing. Piston #1 is also at tdc, but is firing. So set #6 to valve rock, set #1 valves.
Pistons travel in pairs: 1 and 6, 2 and 5, 3 and 4.
So rock #6, set 1. Rock 2 set 5. Rock 4 set 3. Rock 1 set 6. Rock 5 set 2. Rock 3 set 4. This is following the 153624 firing order. Rotate 120deg between settings.
This has the advantage of getting lash correct right at firing tdc, with no doubt about whether lobe is nearby or not.

For my 225, American Diesel sells an adapter that bolts to the pulley and has a big hex head on it. Then you can use a big socket wrench to turn the engine over. They can tell you if you need that for the 135 also. From the pictures in the manual the 135 pulley looks just like the one for the 225.

Here's a picture of our SP135. Ours has the hex head. I have no idea if was a factory install or a previous owner added it.

That doesn't match the picture in "da book". Send the picture to American Diesel and ask them if you can use that hex head to turn the engine. My pulley had the tapped holes but did not have the six hex bolts in them. The adapter mounted to those holes. It looks like you have three grooves? Those six bolts may be holding an add-on for the additional groove.

That hex looks just like mine on my 120... and yes you can use it to turn the engine over...you can even turn the engine over with 2 cylinders hydrolocked...don't ask....
The extra bolts are maybe for the 3rd pulley?

I sure hope so. I have been using that hex head for 7 years to adjust the valves.
