Lot`s of people here have many years experience as professional mechanics (50 years pro, 45 as A&P), and we don`t all agree on everything.

Hmm, seems like most people here thinks the yellow is enough, also found some inscructions from Harley using these bolts (sprocket for a Dyna) and it said that the newer bolts with the yellow stuff don't need extra loctite. I'll go for that. Thanks to everyone that gave input!

I personally and just my opinion think that is why the service manual says to replace them. The replacements have that dried Loctite. I know good and well that aluminum hub does not stretch or hurt the original grade 8 bolts. I would use a Loctite primer in the threads to wash out of all grease. If you do not have that, use lacquer thinner. I personally think the dry threads and friction going in activate it.
If the original bolts look good, I just use Primer T 7471 to clean and permanent grad 35 Loctite on that drive pulley. I use Loctite Medium 242 or rotors.

Ha guys, when it comes to Manufacturer questions, I always go to the source. In my career, I worked for 3 years with a title on my hat Work Methods. Three years was dedicated to working with Engineering, our Four Machine Shops, and our Supplier Company Engineers. .

This is an answer from Loctite engineer Arif Mehmedovic. Interesting but Arif did not think it was their product. They do have a form in tape.

Hello XXXXXX,
Been a while. If there is a product already on the bolt it will not properly work as whatever that yellow product is on there will create a barrier between the Loctite and bolt.
