Reviews
I bought it to use on a Ford tractor, Ford dealer wanted three times the price for basically the same thing. We were able to take this tach drive apart to reverse the direction and so far it works awesome.
The perfect solution to a difficult installation problem The Tach cable now passes through the firewall with a gentle turn - no more broken cables at the tight bend
Perfect fit. Nice product
Looks well built but we couldn’t use it on this customers project. It is rather bulky and heavy. It will not fit above the alternator on small bore Continentals (O-200, O-300/C145, IO-360 etc.) with a Delco 60 amp alternator as an FYI for your planning purposes.

Yes, you would just need to switch the tach cable end fitting to the other side of the unit and it will change the direction of the rotation.
Per supplier: This right angle drive has one end that has the key/tang that goes in the drive and a nut to secure it to the tach drive on the engine, and the other end at 90* to attach the tach cable that has the key/tang that would normally go in the drive, and a nut to secure it. The thread size is 7/8-18.
The grease nipple will have no threads on it. This will have a .263" OD of the largest point on the grease nipple.
2.641" long, 2.205" wide, 1.87" tall.
It does not reverse the rotation.
