Crank going Bad

[POORBOY]

02 Touring ,guy wanted me to see why the topend was so noise,  runout  .005 and  oil pump has  several stress cracks,even a piece of the pump gone,this oil pump looked like it was ready to explode

[Clintster]

How many miles, what mods?

[Hillside Motorcycle]

My question also is the amount of miles.
.005" is not the end of the world,(not what you want though) and we have seen worse without that damage.

[sandrooney]

I thought the 02's were the t!t$ ?

Bike has 26k on it,not sure how many miles are on the build,it has Tman Heads and TR600 cams, Scott if went back with chain drive what about the oil pump if .005 has took this one out.

Would fix the crank!
Just trued and welded is sufficient provided the pinion journal where it goes through the cam plate is not damaged. Look at the camplate bushing and check for wear there.

[02FYRFTR]

Polish the pinion shaft bushing diameter with 600 wet paper, send the crank out to true,plug and weld, replace the wrist pin bushings also if they are scored.  Purchase the 25308-07 for about 358 bucks which includes new cam plate and new style oil pump.  revolution performance or DarkHorse for the flywheel work.  Chicag H/D or jenny at Tri-County H/D for the camplate/pump assembly.

Going to pull the crank and send it out,

[Faast Ed]

Could the pump damage be from broken tensioners?  .005 should not have hurt the pump.

[POORBOY]

Fast it is gear drive,the pump has stress cracks in 3 different places, I would'nt thought .005 would take out the pump, talked to John @ Darkhorse and he thinks there maybe more issues when it is pulled and checked.

[Faast Ed]

Fast it is gear drive,

Whoops!   LOL  I got distracted with the low runout damage to the pump.

I am doing an '03 now that had the same problem only the flywheels were scissored more. Bike was made into a 103 when bought new so he had the stock flywheels. Welded the flywheels, replaced the bearings & started to reassemble but the shafts wouldn't fit in the bearings. Pulled the bearings out & measured the holes where the bearings sit. Holes were beat out of round .005 - .006 & were squeezing the bearings too tight. Getting new cases now. Another reason to go Timken when you have it apart.

[Faast Ed]

Larry, I bet the owner is puking on his shoes.  Very sad story!

[POORBOY]

Nuttin that can't be fixed with $$$   

Now that is a true answer

[Clintster]

I have a question, was there any increase in gear noise? Was the camchest loud any increased whine or any thing of that nature?

[POORBOY]

No gear whine,topend noise big time,lot 'a blowby.
