Bobcat 610 Sheave Re-Install

The decals don't mean anything......they cost a few bucks at any Bobcat dealer or e-bay. The ID plate on a 610 is just below the seat, basically behind your left leg as you sit in the machine. If you can see a serial # you can call Bobcat customer service and they will tell you all the info on the machine. The same plate *should* have the model # also. You're either working with a machine that I have no experience with or someone has re-powered with a different engine than original. Not saying this is the case but someone "could" have simply replaced the stock Bobcat VH4D or VF4D (M-600) engine (short taper shaft) with a common V4 configuration engine (short straight shaft) and then used sheaves from a Petter or Deutz.....slap some 610 decals on it and voila'. Call Bobcat with the numbers you have and see what they say. You've got me interested now.
Yes. See my 9th post within this thread. The original engine was replaced by the previous owner. Ill check the serial number tag tomorrow and give Bobcat a call. The outer half of the sheave has drilled points for balancing and a balance mark the inner half doesnt appear to. So your saying that all M610's had the tapered shaft set up.?

That I am aware of (and I'm certainly not the final word).....in the gas version of the M-610 they used the VH4D with a short taper shaft only. They also had an electric version which was the M-610E and a diesel version that I believe was the M-611 but maybe they were ID'ed as a M-610D. I know the diesel version of the 600 was ID'ed as M-600D. Customer service will probably have that info......if not, I'll ask my friend in ND....he will know for sure but it would take a while to get an answer. Question....is the 'cut-out' in the frame of the machine at the flywheel end of the engine square or round? Again......my understanding......round was equipped with the gas engine, square was equipped with diesel and I have never even seen one equipped with the Reliance Electric motor so don't know how that body was built. Also....to answer your original question.....at this point I would put it back together and see if there appears to be any movement/imbalance in the sheaves when running the engine. Your belt sounds just fine to me......we run them until they are about to come apart before replacing them.

At the flywheel side? or the output shaft side of the engine?
 
It is square, the engine shroud appears to tuck into it nicely.
OK....it's going to be interesting what Bobcat says when you call them with that serial #. Were I looking at the machine without any info what-so-ever......I would believe it came original with a diesel engine and/or not sure of the machine's model #. It'll be interesting to see how far off base I am.

Well I'll see what they say tomorrow, I sure do appreciate all the help and effort. Thank you very much. Ill post what I find out. Good evening.

I cleaned some more of the paint off of the serial number tag and it is stamped M610 and 213621. Bobcat didnt recognize the 213621, they said it isnt long enough to be a serial number but then again they couldnt really answer any of my questions except after referring to the manual they said it looked like all M610's had tapered shaft engines. They did however give me the number of a guy who only works on the older belt drive models and has so most of his life, he's retired but by the sound of it has a huge shop at his place with Tons of spare parts, he still works on them in his free time and he's not to far from me. According to him all M610's were tapered shaft and with mine being a straight shaft he's thinking someone had the sheave machined to accept the straight shaft. Plans are to take the machine to him so he can go over it and see what we can make work. That may be awhile though, we got a foot of snow the other day and the next two days is suppose to be bringing more.

Thanks for the update Bob....unfortunately that's about all the info I've gotten from Bobcat also. You're better off to find someone who worked for them years back so I'd hold on to that phone number they gave you. I realized after looking at one of my machines that you couldn't answer my question about the "cut-out" anyway with the engine still in place. You couldn't see what I'm talking about..... My apologies.
