420c governor worn?

[jdjohng]

Is the pictured damage something of concern or should it be considered normal? The brass washer that goes between the block and the governor shaft is pretty worn could that be causing the wear on the timing gear and timing gear cover? Thanks for any input.

That is similar to the wear I found when I tore my all fuel apart. The governor was junk, and had peeled parts of 27 teeth of the cam gear. I attribute it to oil related failure. Look very closely at the governor weights, mine were loose on the pins and wobbled like crazy.

Yes Lavoy The weights are kind of wobbly and the brass thrust washer is worn out. I have decided not to put it back together without rebuilding/replacing the governor. Is there a rebuild kit available from you for this governor? If so I will add it to my list of parts I will be getting from you soon. Thanks.

On another subject.... I was wondering if you have ever seen the oil supply line for the valve train get plugged or restricted? I took the valve cover off to adjust the valves and it looks pretty dry in there. Thanks again.

No kits available that I know of, I guess I have neer even checked to see if individual parts are available. I usually keep a thrust washer on hand.
I have never seen the oil line plug, but I have had the rear cam bushing installed wrong which prevents the oil from getting to the head, and also starves the rear cam bushing for oil as well. One other possibility is that the cup pluc in the back of the block has been seated too deep and is covering the oil hole to the oil line. Take the line off and start the engine, it sometimes take a few seconds for the oil to come out, but it is not a real flow.
In case your are wondering how I know this, yes I did find out the hard way on an engine years ago.

I bought a pair of governer pins and weights from Deere about 6 months ago and about had a heart attack. Those weights aren't cheap but everything I needed to rebuild mine, was available.

Thanks for the info. I just sent out for a parts manual so I can get some part numbers and check availability locally.
