Anyone adjust engine valve clearance on M 7040 or similar tractor?

It's not hard -- just read the service manual carefully.

However, like oosik said, if you don't feel comfortable, take it to the dealer.

I can't imagine a valve adjustment being more than $250. A LOT cheaper than a new V3307-DI that costs about $6.5k reman, less install fees.

To give you an example, a reman drop in 5.4l 3v v8 crate engine for a Ford F150 is around the $3.5k mark. Still not cheap, but a V3307 costs twice that of a light duty pickup truck engine. So at the end of the day, with install fees, you are looking at probably $8k to drop a new engine in your M7040 if you mess up.

Look go to messicks.com buy the shop manual WSM, then read the detail instruction, then decide. Even if you don't you will know enough to ask the right questions at the dealership. Plus discover lots of new things about tractor that you can do.

How hard is it to adjust valve lash on an M7040 or similar tractor? I bought a new-to-me M7040 that the valve train is getting a little noisy on. The OM calls for a valve adjustment at 800 hours and, while this one only has 625 hours, I'm thinking of doing it anyway. The adjustment itself is likely easy but what about the whole job? Any surprises?

Here is a LINK TO WSM VALVE ADJUST PAGE for the M7040, it should give you an idea whether you want to do it yourself. You can also download the WSM from there for free.
