3400 rolled over this weekend and still feels as good as new.2015 t3.How do you check runout properly.I tried on the clutch and didn't really work.

plugs out and clutch removed Dial gauge on the crank

I was told to leave the plugs in. That way it puts stress on the crank and takes al the play out of the bearings

 

[Cableguy]

Ive done it both ways but when i pushed dealer for a new short block they check with plugs out prob gives them the least amount measured

The dealer will do it plugs out so if you want to be able to compare your number to theirs pull the plugs.

Plugs out is so there is no drag and false readings from the added compression

Makes it hard to spin slow and watch also

Ok, and how about runout? My sled is off warranty in December and my season is done. I wanna go through it before it’s put away for the year.
Thanks.

Well old spec is 2.4 tho, but I heard doo upped it to 5.5 tho

5.5 is too much at 8000 Rpm lmfao

I agree that seems pretty high for something spinning at that speed, but 20 thou runout on a clutch? No big deal.... Anyway, thanks for the info Tex, much appreciated.

2.8 thou i believe is spec. Had a picture sent from a dealer of update specs was about double of what my manual showed when it originally can out..... plus our are so the dial indicator doesn’t jump and it’s smooth rotation. Plus in and out will not effect runout of crank phase. Crank can be check on the bench with v blocks and will show the same numbers

Had 13 thou on mine before rebuild... ran just fine

You mean 1.3 thou not 13 ? Lol

 

[oler1234]

no I meant 13... or 0.0130. spec is 0.0045

That would explain the stator shaking off the block.

Are you sure on that spec I’m sure it was .0024 - .0028 the dealer text me a picture from service info first of this season

 

[Cableguy]

my 13' is at .017 still running but def more vibration in the handle bars
yard sled only now til she blows

It used to be 0.0024, but they upped it to 0.0055 last year I was told in a few different instances , most dealers don't have the newer specs and no idea

Mine was way out dealer tilt me that “we don’t have the proper brp fixture for the dial indicator though so we have to order it first” it was on back order until January. They couldn’t fasten a piece of steel to it or use a dial indicator with a vise grip attachment though wanted my sled to sit from October until December or January lol needless to say I bought my own motor
