Looking for Bobcat SN Information
Posted: 01/02/2009 03:48 PM
I am a new member to this forum and the proud new owner of a 753. I was wanting to know how to decode the serial number to find the manufacture date , options, etc. I searched Bobcat's website but could not find this information. Can someone help me or do I need to talk to my local dealer? thanks

Bobcat dosen't roll like that, other than the first four digits identifying the build group.  After any basic builds id'd by the first four digits, all units are serialized starting with 11001 and are sequential regardless of any factory options that were in the build.

Incidentally, build runs went through the calendar year, so year of manufacture isn't an issue when searching for parts or as an identifier of a certain build.

All parts listings are based on serial number at the dealer.

The dealer may be able to find out for sure.  Probably, some old-timer will tell you he thinks that was “built in 1997 or 98, I believe“, but since it dosen't matter, no one really cares.

Sorry if this sounds nasty, but why is everyone so interested in what year their machine is? It really only matters about the hours that it has done. The dealer only needs the serial number to provide you with the correct parts, not the year.

With that said, remove the covers for the drive motors, have a look at the model plates on the motors, there should be a month/year stamped on them for when they were manufactured, it will give you a good idea, add a few months to that figure and you should be pretty close.

On newer machine I guess its a indication of value, but hours are more important then years for sure. The dealers of most brands can now tell for the last several years when a machine was put into service thanks to computer records.

I think the year thing comes more from vehicles where a title is involved.

Bobcat  has series and serial number breaks where a change in the way a unit was made (which would affect the correct parts required in the future) and series which indicate a major upgrade and finally different model # that progressed as the years went by. some where bigger and other were a update of a earlier #

I general I still think of years for heavy equipment, but its much less of a indication then the hours on the machine, Both of which have to be taken with some skepticism and the overall condition used a the main guide.

Bobcat's website show historical specs for their equipment that is sorted by first year of manufacture. They show the first 753 in 1990 with different HP and pump capacity than one built in 1999 (40hp vs 43.5, 11gpm vs 15.9), which may rule out some attachments that I might want. I understand that machine hours are more important than year (mine has 413 hrs, just broken in) as far as machine value goes, but I want to understand better what my machine is. I'm guessing that it is one of the later models. I will be getting the manual in the next week or so from the seller, does it give more information specific to SN? Thanks.

Mike , there are 6 serial number breaks in the loader technical service book , and all 753's start off 512 or 515 except one break which it doesn't give a serial number.

It only list it as a (nonBICS) machine which is the oldest out the 6 breaks , for the Non Bics it says v2203-b , 40 hp , 13.0 gpm @2480 rpm's @ 2500-2600 psi

To give some reference the next machine up would be 515811001-518829999 which was 43.5 v2203-b@ 14.3 @2650@2500-2600rpm's 

 It then jumps to v2203-eb @43.5 @ 14.8 gpm 

 v2203-e = 46.0hp @ 15.0 gpm , same @ 15.9 , and high flow @ 21.7

Are you sure of the number or model , I'd call the dealer --------good luck in your quest for the truth

I took another look at the ID plate and verified the serial number: 511532014, model 753. This ID plate is riveted to the frame above the radiator screen by the left lift arm bushing. It is a Melroe Bobcat, division of Clark Equipment. I will contact the local dealer and see what they say. I bought this from a private individual, but the dealer's sticker is on it, so they probably have a record of it. I will post what I find out about it. Thanks for looking.

It's always a search. I gave up trying to figure out the serial number on my 843. The ID plate was corroded, so I tried to clean it using electrolysis. Too bad I left the plate in there for a day because I forgot. Only black sludge was left. If I can find the number somewhere I am going to silk screen a new ID plate so I do not have this mystery anymore.

The dealer was able to tell me that this 753 was purchased new in March 1994. I am still waiting to get the manual from the seller, but the dealer loaned me a newer 753 manual. Does anyone know if the lubes changed for the engine, hydraulics, and chaincase?

For my 93 753 (prior to C series) it was 10/30  motor oil throughout. Some members here are using hydraulic oil in the hydraulic system and there has been some debate as to which one is best.  Search oils for the previous threads.

You could run almost any oil in the chain case. Some dump the hydraulic resevoir oil into the chain case and add new oil to the hydraulics. (Be sure to wipe the chain case clean b4 refilling) Both hyd and chaincase have a 1000 hour drain interval. Often the chain case gets water in it from the top covers leaking or cracking from the boom stop slapping the front of the chain case when the boom is lowered too fast.

Engine is generaly 200 - 250 hours, the manual says something like 50 but thats just insane, for a serious operator thats almost every week.

I think the manual should say change after the first 50 hrs, then like 250 or so afterward.

My loaner manual is for SN 515811001 and up, and it says 250 hr interval for engine oil, 10w30CD in engine, 10w30SE for hydraulics and chaincase. I'm assuming that it should be the same for my older 753. Thanks everyone for the tips and advice, I appreciate the help.

You can run the diesel grade oil in the hydraulics too, the beauty of it is you can use the same oil in the entire machine be it hydraulics, engine or chain case. You can even use it in your truck if you cart the machine around.

If you go to the bocat website, and get the phone# off of there and call them with the serial# they can tell you the year of manufacture and the model.
