Rogillio Posted September 22, 2014 Share Posted September 22, 2014 Decided to start on the wheels. There are 8 bolts holding the wood hub/spokes....in each bolt someone cut a slit. I say 'someone' cause it does not look factory. They were very tough getting off with an impact wrench. When I tried to put the nuts back on the bolts they would not go on! After an hour of trying only 3 of the 8 started. I got to thinking about the boltsand why someone would cut a slot in them?! This was the day (1926) before the nylongn self locking nuts. My guess is that someone cut the slits and then splayed the bolt to keep the nut from backing off? Just a guess. What say you?I ordered for new carriage bolts and self locking nuts. The original are not exactly like modern carriage bolts. The originals are more like ovals....or squares with the corners trimmed. May yet try to salvage the old bolts.....but I don't have a tap/die that size. Link to comment Share on other sites More sharing options...
JayG Posted September 22, 2014 Share Posted September 22, 2014 I just went through this exercise restoring my wheels. The bolts were peened so the nuts would stay on. Factory original as this was the case on 2 different sets of wheels that I have. I ended up grinding them enough to get the nuts off then dressing up the threads to save them. I looked everywhere on the internet for bolts to match the originals and they don't exist. The heads are smaller and higher profile than modern ones.

MIClassicGuy Posted September 23, 2014 Share Posted September 23, 2014 We had a couple break off, so we replaced them all with modern bolts from Fastenal. I think they called the "shaker screen bolts" and yes, the heads were larger than the original ones.. Link to comment Share on other sites More sharing options...
cahartley Posted September 23, 2014 Share Posted September 23, 2014 I bought grade 5 carriage screws with the correct length believe it or not...... :eek: ........2 1/4" under the head I believe.After nutting them I used a wicking thread locker to lock the nuts.

Rogillio Posted September 23, 2014 Author Share Posted September 23, 2014 I've got 8 on order from Fastenal. I bought 8 self locking nuts and will use some Locktite too. I got to thinking that the wood is being sandwhich'd between the two plates and wood will expand and contract so I can see where the might loosen. I will keep an eye on them.

cahartley Posted September 23, 2014 Share Posted September 23, 2014 (edited) I just measured the bolts I got......they are 7/16" × 2 1/4" and the heads are 15/16" in diameter.I also bought 7/16 heavy nuts at the same time.I don't know what length bolts you are getting but I'm afraid you won't have enough threads for nylock nuts.
