MG TD TF 1500 - Motor mount nut size

What the heck thread is Moss using on the front motor mount studs imbedded in the rubber. None of my BSF or BSW hardware fits it
W. A. Chasser Jr

According to Moss website it is 3/8 UNF stud & nut
Stuart Duncan 1953 TD

should be 3/8 BSF

part no 311-220 is the nut
but they have a repo version that is unf

310-050

Mine must be und because my new BSF hardware doesn't work. I'm presuming UNF IIs the same as SAE ? To many damn threads to keep at straight! 3/8 x 24 didn't even enter my vocabulary... But I have a few choice new words to add. Lol

Thanks

Well I just came back from the hardware store with 3/8 x 24 nuts and they don't fit either. I'm at a complete loss I have BSF nuts that don't fit I have UNF / SAE. And they don't fit. WT_?

Have you tried metric ??

Yep. I just tried a metric and no go. Looks like I'll be lifting the engine to remove the rubber tomorrow and out a thread gauge on it and / or take it with me to the hardware store. Barring that I'll run a die down it to make something I can use. Very frustrating to take half a day on this one item and still not have it resolved. Time to give it a rest for today...

Cheers

Bill - According to the information that I have it should be a 8 X 1 mm thread, which seems a bit small to my thinking. Whether it is 8 or 10 mm is is going to be a thread that is not available at Agent Orange or Lowe's since the studs used in the TD are an obsolete French Standard metric (either a 8 X 1mm or a 10 X 1.5). That said Moss Motors may have something completely different. Cheers - Dave

McMasters has them.
Listed as fine thread metric

Dave my hardware store had 10m x 1 and it didn't work either. I think 8m is too small. Tomorrow I'm taking the part with me. I'm just so fed up with hardware issues. Now I need the screws for the brake switch terminals. Mine were missing. I also can't find a bolt for the Dynamo
Adjustment arm slot the thread in the front plate is coarse thread (?)

Phone Moss about nuts. The mount I bought last year came with nuts. Perhaps yours were left off.

Hi Tom

Tom, Unfortunately the mount I have is old stock that came with the car. I have no idea how old is now or when it was actually purchased from Moss. There's likely no way of knowing if there was a manufacturer change as to the thread at this point I will have to do further sleuthing once I take it back out of the chassis

Jim & Dave, My local hard ware store has 8m x 1 & 1.25 pitch and 10m x 1 (?) and 1.5 pitch surely one of these has to work.

Will try again this AM

Cheers

If it is NOS and truly OLD, not sure I would use it. Rubber gets hard and brittle with age. I'd get a new one.

Tom It is not NOS. Repo part but it came with the car when I purchased it. I just don't know when it was purchased. It is solid condition with no deterioration of the rubber and the vulcanization is sound.

Cheers.

Bill when you get your nut issue sorted check to ensure the crank handle still engages the pulley when offered through the radiator cross member. I had to pull my AM front mount out again & fit a plate under it so I could engage the crank handle. Cheers

I finally found the right combination. 10m x 1.25. Thanks all for your help
