Automatic primary chain adjuster

[seniorsuperglideE8]

Installed the Hayden M6 on both bikes. Two springs under the shoe keep the chain just right, hot or cold.

If you give the ratchet a helping hand and force it 1 more click than it would naturally want to do, then you can run into losing the remaining shoe spring when hot and cause an overtight condition. Just cut the tie wrap and walk away from it. It will set itself and work fine. Two exceptions that could promote over ratcheting are beating the bike before a good warmup, or brutal torque from a non stock engine can between the extra pull on the chain, which has some elastisity and shaft deflection might allow the ratchet to end up going tighter than it should.

Bottom line - if installed correctly without forcing the shoe upwards on installation, all is well. Where then are the springs in the bottom of this unit? From what I've seen, there aren't any. What am I overlooking? Thanks.

They are under the shoe. Two , if I remember correctly. When the chain is tight on the top from the ratchet, these give an additional 1/2" more or less to keep the system from going totally rigid, like when the chain gets tighter from heat. Consider this as the working zone, and the ratchet as basic initial adjustment.

Well guys for what it's worth I just listed it on e-bay. Hope this is appropriate:

I used the aftermarket hydraulic chain tensioner on Booth my bikes, they have performed flawlessly and I would highly recommend them. Easy to install and then forget about them.
