Valve lash. Why does the manual tell me to call the dealer?

Going down the list of maintenance tasks on my Deere 310L backhoe, one of the items is "adjust valves".

Under this heading, it says to "Call the Dealer".

Curious why this is a dealer issue?

I can't do this with a feeler gauge and a wrench?

I think it is a case of trying to protect themselves from liability or just trying to push more work to their dealers!

Would not surprise me to someday see an owners manual that under "check oil" for them to say call dealer!

Valve bridges are the usual culprit that make people nervous when adjusting valves. I always loosen the rockers up, loosen the lock nuts up on the valve bridges, set the bridge adjuster and then set the valves. After all are set, then I go back and check the torque on all the valve bridges. Anyone who has seen the damage of a loose valve bridge adjusting nut will know what I'm talking about.

I'll echo the comments regarding the complexities of adjusting valve bridges, but I have a question. Does this particular engine have screw-type (adjustable) or floating (non-adjustable) valve bridges.?

Maybe mg2361 could comment.

When the Deere tech comes out, I'll watch him do it so I know how next time.

words can’t describe how much disappointment I feel. Here I was, silently following along, thinking that somehow you were gonna stick it to the man and HEF as a whole would bask in a small but significant to us victory and then you went and invited him over.

I'm looking upon this as a way to get the lug nuts loosened, a bunch of questions answered, and I can watch him do these jobs so I can do them next time. It's worth the price to pick an expert's brain for an hour or two.

Im curious as to whether your tech will be reading from the service manual while doing the job.

When I worked for end users, putting a young person with the dealer wrench was always cheap on the job training and you got more for your money. Part of my consulting services was working with client newbies getting them up to speed on maintenance and repairs.
