MG TD TF 1500 - What's wrong with this pic - TF gen.

Gents,

Something is amiss here. A little guidance would be very much appreciated.

Generator #22258E Mfg. date 9-56

Pulley measures 1 3/8" from back of pulley to center.

When mounting the old pulley to the new (rebuilt) gen. I was unable to draw the nut down more than a half nut.
Do I have the wrong pulley?

Is this correct? Seems everything lines up.

The top bolt should be either Whitworth thread (not BSF, not metric) or UNC.

Dan, Looks like there is space between the rear of the generator pulley and the fan plate. The pulley should bottom out on the fan plate when the nut is tightened. You must resolve the issue with the generator shaft nut threads -- you mentioned the nut would only go on half way. Frequently, a spacer washer (about 1/8") is needed at the front lower pivot bolt to move the generator forward a little, and correct the pulley alignment. Yes, the adjusting link mounts like you show it in your last photo--- Bolt from the rear.

Richard, When I placed the fan onto the shaft it went past the key and thus would just spin freely. I decided to place a washer between the fan and the generator so the fan would land on the key. All that worked well except it moved the pulley outwards as well thus leaving very few threads left for the nut. When I found my old original nut I noticed it was much thinner (more like a jam nut) and when used it gave me almost a full thread.

Does that sound safe?

There's a spacer on the generator shaft that butts against the front bearing and then the fan butts against this spacer. Its normal for the fan to go beyond the key and since the pulley is tightened against it when the nut is torqued, everything is secure like that. I would remove the washer you used, so everything is as its original configuration, however, the washer you installed probably won't hurt anything as long as the nut is tight. Its important for the pulley nut to be secure so there's no chance of it coming loose and parts damaging the radiator. I use a strap wrench to hold the pulley while tightening the nut and add a little blue Loc-tite.

You pretty much described what I did. Bless those strap wrenches.

Thanks for your help.

Dan - here is a series of pictures I did for fellow T Register member, John Brickel when he was having the same sort of problem. Cheers - Dave

Thanks Dave.
Your pictures will help me to confirm what I did is correct.
I think the distance collar provided with the generator is too short. I was also concerned that since the fan was notched for the key it should not just pass over the key but stay engaged. Since reading yours and Richards comments it sounds as if its not that important.
Dan Nordstrom

Been a while, but I think the notch in the fan is just to let it slide over the key, and that it does not engage. It looks like you have space between the front generator plate and the lower mount arm. Make sure you use washers or spacer to fill the gap(s) and make sure pulleys still aligned well. George
