Ford 2000 3CYL Tach Drive. Alternator or Oil Pump

[bwalsh]

I have a Ford 2000 3 cylinder. I think its a 75 or 76. The generator was replaced with an alternator. The generator had right angle drive for the tach cable and the alternator has a straight tach drive. I've been through 5 or 6 drive cables. With the straight tach drive off the alternator it routes the cable right past the exhaust manifold with several sharp bends. I've tried different routings and heat shield jackets on the tach cable. Nothing works. My questions are: Does anybody make a right angle drive for an alternator? Is it possible to convert a gas 3 cylinder to an oil pump tach drive? Any help is much appreciated.

Its new enough to be made in to oil pump drive, Have to replace oil pump drive gear along with tack or cluster. Rotation changes to LH

I'm guessing that oil pump drive gear is located directly underneath the oil filter. Is it as simple as removing the plug and inserting the new drive gear, then replacing the plug with the tach adapter? After doing some google searches it seem like the cluster out of a 2600 will work. The pictures of the 2600 cluster are identical to the 2000 except the tach scale is reversed. So I imagine that will work. Thank you for the reply.

Serveral ideals... first off get a bigger belt.. so that the alternator is now further out from the engine... second, reclock the alternator so that the mounts are rotated to move the feed to a more advantages location. third, get a 4 cyl tach cable that is longer that has more room to be re-routed.. forth reverse exhaust pipe from vertical to horizontal... And finally the early block have a threaded plug over the oil pump drive and they cant be converted easily or at all. The later blocks had the press in plug and that block can have the "press in" tack drive installed, but its the reverse direction, meaning you will also need a new instrument cluster. I have had very good luck with the alternator conversion myself on around 10 or so tractors that I've used it on, but i stock the 4 cyl tach cables.

I know they sold aftermarket alternators with tach drive on it but I've never had that style. If your tach/cluster is good reclocking and cable from a 4 cyl 5000 will be cheapest.
Though I prefer horizontal exhaust on that size tractor I don't think you need to do that here.
If you go oil pump drive gear route you need a new tach too.
Simple to change the gear.
Dig the pressed in cover out, pull the gear out with long pliers and drop the new one in.
Bump the starter while you press down on gear to get it to mesh and drop in. Replace cover with drive for 2600.

75 was the last year for the 2000 model, 76 would have been the 2600 model
I’ve installed a few of those Delco conversion alternators with tach drive, on every one I’ve had to unbolt the back case and reclock (rotate) the case to get the cable away from the exhaust manifold, on Delhi non tach drive conversions I still reclock the rear case to move the wire plug away from the side of the engine

I changed to oil pump drive on one of my Fords...forget what it took but was no biggie. ebay had the adapter and installing was no biggie. Don't remember anything special about the display having to be changed from cw to ccw or vise versa. Don't know when Ford changed from the generator to alternator requiring opposite directions for the instrument cluster.

It was late 75 - for the 76 X600 models

I purchased a right angle adapter from these folks when I switched to an alternator with tach drive. It maintains the same cable path to your alternator that you had with the generator.

Thank you for the information about it being a 75. I wasn't sure. That right angle adapter would have been my first option. Unfortunately I already ordered the parts for the oil pump drive. If it turns into a hassle I'll just by the right angle adapter. It looks like my oil pump drive gear cover has threads on it. The one I ordered has an o ring. If that's the case I'm not gonna mess with it. Once again thanks for the info.

If your oil pump drive cover has a Allen hex threaded plug your tractor or it’s engine is much older than a 75 model

According to an old parts book, they switched from the screw in cover over the oil pump drive to the press in cover on April 1, 1971.

Interesting about it being the wrong oil pump drive cover. I guess the engine was switched sometime in its life. I ended up ordering the adapter from texasindustrialelectric.com. I was stupid expensive but worth it. By the time I bought a new cable, cluster and changed the drive gear, I thought it was easier and more cost effective to buy the adapter. If fit right on with no issues. The tachometer reads exactly 300 RPM higher than actual. I measured with a digital tach on the balancer. Thanks again for all the info.
