Auto CCT cross reference

Yes that's right. But it seems odd that they are metalling the manual ones, as per the pic, I response to a perceived problem with the type of ACCT that we, including me, have put on their XS1100s. I've left my automatic one on the XJR

[bikerphil]

James... my guess is that eventually the auto tensioners could fail causing extensive engine damage and the person that it happens to (or person reading about it) may not trust them anymore. They may then choose to go to a threaded manual type tensioner that positively will not fail. They look bullet proof unlike the OEM XS type with the flimsy sliding plunger and lock down bolt.

All really that it would take for one to fail would be for the small little spring on the ratchet mechanism to fail and then in theory the plunger would be free to go in and out except for the main spring.

Yep Nate, if the ratchet should fail, I would bet that beefy spring would keep the chain from skipping teeth, we should hope.

hey bonz, I went to the bike salvage yard here in phoenix and for $20.00 got my acct from a venture. took about 10 minutes to install it without any modifications. well worth the time and money 'cause when I got the original stock unit out it was bound up and probably not working correctly at all. my bike only had about 13,000 miles on it so probably no damage done. knowing what problems can come from a bad stock unit i'd gladly pay a premium price for an acct unit. i'd be happy to go see if the other acct unit is still there. let me know.

Yes, IMO, changing the Xs1100 OEM assembly is a must. The manual one in the pic is pretty foolproof, I would say. The thing is, on the XJR, the OEM tensioner really is something strong looking, so it seems unnecessary to remove it, especially since the 'upgrade' on the XS1100 is probably not as strong, if you see what I mean. I dare say that the one in the pic would fit an XS1100 actually...... Maybe?

Now I do not see where the manual one James presented could fail it is the best fix. However I do see where people unfamiliar could torque that thing down and really create problems. Most failures in these machines come from someone at some time not doing a proper adjustment or using the wrong oil and some not doing anything (run it till it breaks).

The biggest possibility in failure of the ACCT I see would stem from the dependability of it. The tendancy is if it has no problem to leave it alone. The issue I can see is our oil tends to pick up fiber from clutch and become some what gummy. After long periods it could stick to or settle into the teeth or the spring of the ACCT. Then as the unit feels slack it tries to move to the next tooth and can not get a good grip so it could sit there for a long period just barely having a grip till the old tooth filled also. Now you have a unit the is not far from slipping and having no locking action at all just a spring.

My thought process to avoid this slip is maybe once a year to take it off clean it check the spring action of the catch mechanism for crud and gum, clean inspect and reinstall.

Wow, thanks for pointing that out Ron about the maintenance of the ACCT. I would have never thought about checking it till you said something. There will be a point down the road where I.want to go over my bike's electrics and make sure all is working. Plus, I'll maybe do an HID conversion and put Tkat's fuse box in.

[natemoen]

put Tkat's fuse box in.

Just for clarification, tkat only does fork braces. TopCatGr (or TC) has the fusebox.
