MG TD TF 1500 - Fan Belt

Season's greetings to all . Are both fan belts sold by Moss Motors suitable for the T.F. Given the location of the generator gear box for the R.P.M. reading . Thank-you John

Please excuse my vagueness in posting the question on the fan belt . The fan belt when adjusted must allow the generator R.P.M gear box drive cable to clear the distributor assembly . Do both belts sold by Moss Motors provide this requirement . Thank-you John

A soft flexible washer under the reduction gear box coupling at the generator will allow you to position the gearbox in any position you desire without it flopping about.

Other choices are small brackets going to the grease fitting to stabilize the gearbox, or relocating the contact breaker lug at another position by reinserting the distribtor.

The biggest variant due to the fan belt selected is the ability to install and adjust it without being too tight. Try reading Dave DuBois article for belt information, and shop at your local auto parts store for his suggested belt.

John - Use the part numbers for Gates or Goodyear in the Article, Keep Your Belts loose in the Other Tech Articles section of my home page at: http://homepages.donobi.net/sufuelpumps/ Either one will be sufficiently long to clear the distributor and sufficiently flexible to keep from causing excessive wear on the generator bearing and bushing. Cheers - Dave

FYI: the gates number in Dave D's article fits smashingly in a TD. I put one in my TF and it does indeed fit, but it puts the spinning pulley fan a little close to the left headlight wiring loom. I put in a small P clamp to hold the wires back more for my own piece of mind.

Also, the gates numbers directly transfer to NAPA numbers as Gates makes the NAPA branded belts. Sometimes the staff don't know this.

John,
Here is some other methods of securing the reduction box. The first one worked but not too pretty or stable.

The second one is much better. Just a piece of thin sheet metal.

Much better. I think it was Dave Sheward who posted one very similar. That's where I got the idea.

I installed my distributor 180 degrees and avoided all of this. Regards, tom

If the distributor is installed as pictured in the workshop manual, the primary terminal is out of the way of the tach reduction gearbox. There is also a washer that is supposed to be in the connection to the generator, it doesn't move around. Cheers - Dave

Gentlemen . It is truly remarkable how responsive the members of the B.B.S offer their full assistance and suggestions in how to resolve so many issues we encounter in maintaining these little gems . Once again thank-you . JOhn

The way to deal with the tach reduction gearbox is to repair the incorrectly made pinch clamp. Run a hacksaw down the slot to widen it, drill out the threads and replace the pinch bolt with a machine screw and nut

I had previously widened the slot but never got enough tension on the pinch bolt before I broke it(several times).
I like the simple idea of drilling it out and using a nut and bolt. Now why didn't I think of that? Duh!!!
