case 311 rounds nose parts needed

Check your tach this way. Looking at the back of the tachometer, if you spin the brass drive sleeve CW with your fingers the pointer should jump. Don�t force it with pliers, use your fingers only.

The link is a thread that is relative. 311B is the same as the older 300.

Amp gauge is not voltage sensitive, will work on either 6v or 12v.

The mechanical temperature gauge is obsolete, no new drop in replacement. They can be repaired, very spendy, $200 - $300.

If you convert the tractor to 12v, electrical gauge movements and senders are available for both gas & temperature and installed in the gauge board with the existing gauge faceplates function & look as original. Pos or neg ground is not an issue.

Roger Hornbaker does 300 gauge board and instrument repair & refurbishment. He can provide some other hard to find 300 parts as well. You won't deal with a more honest or nicer person.

John may have the sending unit, but if not I would bet that NAPA auto parts has it, they have a lot of stuff for old tractors.

Look at his card in the store John or Chris, his wife, will answer. Again these a real nice people and very good to deal with.
