[mrbb]

OK guys looking for suggestions have an older (1999) new holland LX 865 I am having issue's with starter , that after its started the starter keeps going, for 5-30 seconds then stops I replaced the starter with a new one, still have issue replace the key switch with a new one,thinking maybe was holding energy now wondering what else it can be??

Under the engine fuse and relay box are to solenoids. The one to the outside is the start solenoid. Replace it.

sorry on delay here, but thanks I will order a new one, and by any chance would you know a part number for it?

I have a Bobcat mini excavator that did the same thing. Here's what a buddy told me to do: 1. Tighten up the starter mounting bolts and the cable connections. If it's loose it will flop around and the bendix gear will bind up on the flywheel when you hit the key. 2. Put a new battery in it. He said he's has several trucks and semis over the years where the starter bendix wouldn't release because the starter wasn't turning fast enough to release the bedix off the flywheel ring. I actually think my excavator has BOTH problems because I installed a new battery, but you can still hear a slight "knock" once in a while, like the starter is binding up.

thanks for suggestion but don't think thats my issue here its a new battery and always kept on a battery tender, and I swapped old starter for a new one, so all bolts are tight haven't had time to screw with it yet, but just got a full service manual and will be digging into things mroe when weather gets warmer so still open to suggestions or thoughts/idea's till warmer weather comes!

Right, I'd do exactly as Mike 10 suggested. 99% of the time the solenoid is the problem. Most diesels have an externally mounted solenoid that activates the starter-mounted solenoid. The external one no matter what diesel commonly goes bad. And the increased speed of the flywheel is what "kicks" or spins the Bendix drive back in, the instant the engine fires not the starter itself (other than help from its assist spring). Same with the big Delco's on Detroit Diesel and Cummins engines in semi's. Once in a great while a Bendix drive can bind on its shaft and not spin back in due to an extreme amount of crud on the shaft, but that's rare.
