Balance damper replacement questions (post-tuxedo mod)

Hey everyone,

Long time no post. I recently threw on my manual cam chain tensioners and the engine quieted down a lot. At that time I started to notice a light knock/tap in the front area of the engine. After fiddling with the MCCTs I realized it definitely wasn't the cam chain, and read-up on here. Looks like it fits all the tale-tale signs of bad dampers. Old bike (86), light sporadic knock up front both in gear or neutral, but not noticeable off-idle, and plastic in oil screen.

After seeing the horrific pics of what happens if you leave this unattended, I immediately ordered new dampers and a 18MMX1.5 flywheel puller (here). I am hoping to see them before next weekend, pending cheapcyclepart's turn-around time.

The tuxedo mod has been done on my bike already, so this should be a fairly simple process?

Since I will be making my own seals, is there anything else I am missing/needing to get this done? I'll check on the stator once I get in there, but if it's all good I'll leave it be for now.

Any further guidance would be very welcome.

I am just hoping to have my bike all ready for the warmer season so I don't have to deal with downtime for stuff like this. I have a lead on another vn750 as well, maybe for the wife. She may kill me if I end up with a second, though.

I believe the engine will still have to come out to do the balancer. If so, it's a shame you didn't go ahead and pull the engine before you did the mod, so you could have done everything at one time, and not gotten metal particles in the engine from doing the mod with the cover in place, if that's the way you did it. If I had to do a stator, I would probably do the balancer at the same time, even if it didn't need it. It is 10 years old with 70,000+ miles on it, so if I have to pull the engine anyway, it just makes sense to get a new one. With the engine already out, and the cover off and far away from the engine, I might very well do that mod, just in case the stator failed again.

I am a motorcyclist, NOT a biker.

The PO performed the tuxedo mod, so I also wish he had done the dampeners to save me the trouble!

I am finding conflicting information in regards to needing an engine pull. Since it resides behind the stator, shouldn't I be able to access it?

I haven't been in there yet so this is all speculation of course.

Yes it's behind the stator but in order to properly get to all the components that naad to come out to change the balancers, you will have to remove that casing the stator mod was done to.

If you don't have a copy of the repair manual I suggest you download it from my sig & read thru it. You don't have to completely remove the engine but it does at least have to be partially removed as to be able to get the a couple of the bolts.

Stupid design I know but once you do the balancers you should be good to go for a while. Don't overlook the ballancer bushing on the other side though!

Oh well; I can't win them all.

Is the bushing you are referring to PN 92027A (COLLAR,20X28X19.5), or 92022 (WASHER)?

Should I be replacing the same on the stator side? I see PN 92027 (COLLAR,16X24X8.5) and 92022B (WASHER,10X32X4.5) relating to that side. Here is where I am pulling the PNs from.

Thanks for the continued help everyone. I hopefully can get everything ordered by today so that I can tackle this job over the weekend. I can't stand being without my ride now.

OMg, what a brain fart. Sorry about the confusion. Tha balance gear on the other side doesn't have bushings.

No worries there. I felt it better to ask and clarify than to assume.

Thanks for double-checking for me. All needed parts are then en-route!

It looks like I'll start this job tomorrow. I am hoping to pull the engine after I get off work tomorrow, do the damper installation Saturday, and finally being able to start her up Sunday (24h for the gasket maker to set).

I know there have been many articles and pics taken in regards to an engine pull; I'll try to expand upon them and write an in-depth how-to with pics on my Wiki.

Any advance advice is helpful!

I think If I had an '86, and I was going to pull the engine for partial dissassembly, I might consider replacing the Shift Linkage Tie-Rod. It is known to be a weak part of the early model shifters. Not sayin' I would do it, but it's somthin' to ponder.

Wish I had read this two weeks ago! :P

Oh well, I figure it will just get easier to do with each pull anyways. I have to do it on my '90 for the stator (and dampers, might as well) as soon as I am done with my '86's dampers!

Fun times.
