Just got my engine (235) back from machine shop. All in pieces.
When I brought the engine to shop the pistons , crank shaft and cam shaft where installed.
Now all came in a box and when I tried to install the cam shaft and match to crankshaft, I cant find the marks on the fiber gear. The only two marks I could see are the logo and on the oposit side two faint 00. How can I get the correct setting to have the timing where it should be.
Don't forget I am a novice and need simple explanations.

There is enough good in the worst of us and enough bad in the best of us that it does not behoove any of us to criticize the rest of us. - - Be yourself. If you are ever lost, It will be much easier to find yourself if you know who you are!

I had the experience of having the fiber gear let me down and I was not amused. | | | | | Joined: Feb 2001 Posts: 1,096 'Bolter | | 'Bolter Joined: Feb 2001 Posts: 1,096 | I recently did a rescue job on a '39 truck ,, the owner was driving to Auckland ( 1000km away) he got 180km in the middle of the night and the engine stopped !! , sounded like running out of fuel ,, only the valves weren't going up and down ! Yep , no teeth on the fibre cam gear ,, this engine had had big $$$ spent on it too ..  | | | | | Joined: Jun 2000 Posts: 2,773 'Bolter | | 'Bolter Joined: Jun 2000 Posts: 2,773 | The difference between the car and truck 235 is the gear. Cars used fiber, it was quieter (especially after it broke) and the trucks used aluminum, a little noisier but far stronger. I have to admit, I have never seen a 235 with a broken aluminum gear.
