Hi,

Everyone I'm new on here and new to being a cat owner. I'm trying to figure out where the serial number is on my machine. I think it's a 951c but not 100% sure it has 39 pads and was told the motor is a 3304 ritchiespec says that matches a 951c. My friend that I bought it from had thought it was a 941b. I attached some pics there are part numbers all over but nothing that looks like it matches a serial number.

Thanks

It looks like a 951C? but it has managed to get its tracks on back to front, it looks a nice lump of iron, it might have a few bits missing Bonnet, grill plates, return to dig control, etc

Hi Jared,
welcome to the BB.
From memory on these units the plates are normally located on the rear face of the transmission case--likely covered by the ripper mounting plate, the left side of the engine block--looks like you may have a remanufactured engine or short engine by the 0R number stamping shown, and on the rear face of the dash plate in the operators compartment near the brake pedals.
Cheers,
Eddie B.

Thanks for the fast response yeah a few parts walked off it was sitting a tweakers starte taking the metal they could carry off it did have a rebuilt motor from what I was told. What is the return to dig control? The rear fa e of the dash plate do I have to take the dash off to see it? That would be a lot easier than the rippers. Will having the tracks on back to front make any problems is it worth switching around?

I found that link on here for serial number locations the one on the dash is not there and nothing on the engine I'll look closer at the rippers tomorrow. Where is the bevel case gear looks like it could be in the back under the ripper mount?

Is there anywhere it is stamped or cast into the frame? I think they may have taken the plates of when it was painted and didn't get put back on.

Hi Jared,
if a plate was never situated near the pedals then it may have had one on either side of the main frame at the lift frame tower, at about floor plate level, near the grab handles--no need to remove any covers to see the plates other than the ripper frame over the rear case or the engine one if side covers are fitted.
The "return to dig control" is British for Bucket Leveller--it is a mechanism that will return the bucket to pre-set adjustable flattish floor position so you can dig the next bucket full without manually setting the bucket position each time.
It is normally mounted to the right tilt cylinder. Nice to have but not necessary as they were usually troublesome.
Cheers,
Eddie B.

Edit Tilt Kickout is on right tilt cyl--brain fade. Thanks Tony.

The build date and some times a Serial No is often stamped on the side of the loader frame arm on the nearside close to the main mounting pin area, if there is no detail there look on the hard bar that is bolted to the track frames, this detail will be stamped on the exposed area if the track frame covers/guards were fitted, this is near the adjuster flap on the off side, you would look at it in the same stance that you would look at the flap, the return to dig feature is a first class aid to being a fast and smooth operator of this mount, there is other pointers that are on the bucket tilt linkage that you can see visualy but for speed and neatness this feature is top draw, as for giving trouble well you do have to oil it now and then, but it does not change the fact that your tracks are on back to front???

p.s. the return to dig valve and linkage is "always" on the right (off-side) tilt cylinder as you are sat in the seat.

The 941 came with 38 shoes, the 951 has 39 or 40.

Thanks for the help

Edb I checked there and I didn't see any serial numbers in those locations.

Tctractors I guess I should have got back on here sooner I was just out at playing with the tractor today I'll check those spots tomorrow. I'm far from fast and smooth but it still gets stuff done I almost got it paid for with my first job clearing fence lines for one of my jobs. Oil what? Should I just leave them the way they are that's what I'm hoping but if will cause premature wear I'd rather change it.

Old magnet it does have 39 pads

The only time I came across a 951B with a similar problem was exactly what TC says, all the crud in the cooling system seems to collect in the ends of the two oil coolers, thankfully, the later 951C had an air to oil cooler alongside the radiator for the transmission.
Another way to identify the machines is that the 941 has D4 size 6.75" pitch U/C, the 951B is 6.75" D6B U/C and the 951C is 6.91" pitch D5 U/C.
