Peter, did you do your belt? I am mulling it over on my machine. My rational is that the deutz is an interference engine, although it looks like if you bend a rod (which appears to be the result, no bent valves) they are very easy to replace.
I haven't done it on my PT. I have a few more hours before I get there. (3000 is the recommended change point on agricultural use.) I watched someone else do one. The two pins align the engine and lock the cam and crank, which makes it easy.
There is a nice video on You Tube from Foley engines, who also Deutz sell parts.
If it were me, I would unbolt the engine cover and tip it over toward the left side to get reasonable access to the timing cover and to the two pin chambers.
The Deutz is an interference engine, but it seems to tolerate timing belt accidents with bent valve push rods, rather than broken pistons. Yes, the replacement is quick. All you might need besides the push rods and bolts is a new valve cover gasket. It is a good excuse to adjust the valve clearance when you are in there.
Reminds me of the old joke about whether the patient will be able to play the violin after the operation.
Have a look at the video, and see what you think, given the tools that you have. I don't know how much clearance the 1430 has, fore and aft. You need to be able to unbolt the V-belt pulley and pull the cover.
There's Tim's naval method of cutting through the tub to make an access port, doing the repair, and welding it back up again. It all depends on your tools, talents, and time. :laughing: In all seriousness, a single hole large enough to get a socket in, and you would be home free, just rotating the crank enough to bring the next bolt into position.
Take photos when you do it, please! It would be great to see.
