So I bought a supposedly serviceable crank off Ebay

DOHCFOX · Post by **DOHCFOX** » August 6th, 2008, 8:33 am

And when I measured thrustwasher-counterbalance clearance, I found that it measured .043". The service limit is .040". I also noticed that the drive sprocket collar had a sizeable groove in it, indicating that the crank has more hours on it than advertised, which will doubtlessly cause spooge issues. I wrote to the seller, a 'Dr. Ilja Hermann', and he responded by saying:

Hello JT,
Thank you for the message. I am sorry for the delay in response - I have
been on a short hike with family since Friday.

About the crank:
All critical dimensions were indeed inspected myself before listing
(metrology is my background, earning my living with in R&D for a major
test equipment manuf. in the silicon valley), and privately I keep
service protocol for every riding hour with my bikes (Rode/raced/passion
built my CR 500's from scratch for 18+ yrs). By experience I know that
there is always room for subjective interpretation wether a part needs to
be reworked (if possible) and/or replaced. However, I am also well aware
of handbook clearances, but after working with brand new cranks and
rebuilding used CR 500 cranks myself, I know that the mentioned clearance
is hard to judge objectively as long as you do not characterize the wear
of the axial bearing thrust washer itself + overall counter balance
width. Just to give you an example for a used, never serviced crank - the
latter can vary by up to +- 30 microns around the nominal width 68.00 mm,
so that a clearance can be easily <0.04 (0.038 in particular case) in
even for a crank with obviously worn thrust washer (radially varying
thickness). I would clearly indicate this with immediate service need
(rod replacement) as the axial bearing lubrication would not work anymore
reliably and the entire crank would fail soon. This was not the case for
your crank, and if otherwise, I would have replaced it (still would if I
should have sent you not the one on the picture by mistake). Regarding
the collar I would like to say that the probability of leaking is zero
with new seals as long you have uniform circumferential wear trace as the
loss in normal pressure is caused mainly by wear of the gasket lip and
not the metal counter part. Usually, those collars last 2-3 lower engine
rebuilds with 120+ hours of total use, and though inexpensive (new
roughly $10), you still can have a used one performing like new if your
wear track is not too wide (<0.06in), so that you may install the seal
slightly off the original position not compromizing function and
performance at all. I also could send you another one, though I think you
won't have any problems with this one as well as the crank itself. Please
let me know what you think though. Thanks again.

While the seller (who I am not bad mouthing) had a lot to say about why the crank he sold to me is actually serviceable, his claims seem contrary to real world experience documented on this site and 'that other site'.

Whatcha'll think?

What did you pay for it?

was that the one you outbid me on?

I think it was around $150... I think.

If a seal needs to be repositoned from the original position that is a clear indication that the part is not satifactory. What he is saying is if you fudge it it can be made to work.

Why take a chance on the single most important, and hardest , part to replace.

My point exactly!

Funny thing is, I think my other crank is still in spec, if I measured properly it's at about .038". I'd bought this one off Ebay on a whim as a backup.

that dude parts out a crap load of bikes on ebay and always has these funny hour claims. I think he just buys some bikes locally and parts them out. I've probably personally seen him part out atleast 10 cr500s on ebay.

Exactly I watch a lot of parts on ebay from him and everything he sells came from his gently used 19xx cr 500 with only 20 hrs time since new blah blah blah blah........

I think he just buys cr5's and parts them.

DOHCfox I would be asking for a refund. Last time I saw it he had 100% feedback and he probably wants to keep it. I would ask for a refund ASAP.

DOHCFOX · Post by **DOHCFOX** » August 6th, 2008, 2:36 pm

Let me see if I can even leave this guy any feedback as it was many weeks ago that I received the crank. I'll certainly look into it. My reply email to this guy will say something like:

Inspite of the technical jargon that you used to try to snow me in your email reply, assuming that the drive sprocket collar is the original unit, two things are known about this crank:

1) Utilizing factory recognized measurement techniques, it is obvious that the crank thrust washer clearances are out of spec, certainly so much so that any 'subjectivity' becomes meaningless.

2) The groove in the drive sprocket collar is sufficiently deep to cause transmission fluid to leak past the seal into the crank case. Your suggestion about installing the seal at an offset to the groove in the collar means that the seal would be improperly installed and would create further compromise in the operation of the motor.

Contrary to your hypothesis about collar tolerances and sealing ability at the collar/crank seal union, practical experience shows that nothing short of a flawless drive sprocket surface will prevent leakage of transmission fluid into the crank case/combustion chamber area.

Should I also accuse him of being a tool for trying to outwit me with his technical jibber jabber?

Wait until you get your money back first and then write that in his ratings for everyone to see.

Oh and Bob I'll take all the games the Angels aren't playing in.

He ask's why?

I tell him I want to see the managers fucking face when I pull $330k cash + 2 $200k CD's out of the bank over the principle of this.

You dont pull some bait and switch bullshit like that... on anyone.

He's sitting in the seat right next to me tonight. Hope he enjoys the FULL beer I'm spilling going down the back of his shirt, and the constant farting.

I just went to AM/PM and had 11 ( thats all they had) of those super shitty " Johnsenville Brat's" they sell there. God Damm they make you fart.
