So rushing because my wife wanted me inside….(her fault) just kidding, I had taken the valve cover off and not noticing the gasket got pinched. Went to tighten the valve cover on the center down and snapped the stud in the middle. Tried drilling it out but wouldnt budge so I said oh well I’ll just get a new camshaft holder. Well now I can’t find a part number for this damn thing at all. Called Partzilla and it’s the only part not labeled on the cylinder head diagram. Anybody know a part number for this thing?

It’s a 2018 Honda Pioneer 1000-5D

Honda knew exactly what they were doing with this one

That's how the majority of OHC engines have been for years, the CRF/R models have used this setup since 2003 . The clearance for the camshaft oil has to be a certain thickness and the only way to be sure it stays consistent is to have the caps line bored/honed to keep them straight.

You could most likely get that bolt out very easily and save that cap.

Can’t u just take the cap off. Weld a nut on it or set in a drill press and whittle out ?
Or even drill it out and replaced it with an insert. I've done it on the CRF dirtbike heads before, because their set up the same way. You can't buy the caps without buying a head.

👍 way better than a new head assembly
