Thanks Timm9, This unit has only 17 hrs on it. Hopefully it something as simple as a relief valve. It that doesn't work, perhaps a blower motor change out is the best option. Do you have any specifics on the new motor you are happy with?

DEWFPO,

I can get you the actual Char-Lynn Motor number if it would be helpful as I have a spare on the shelf in the shop just in case. The lead time for the motor was 5 weeks. My only concern in suggesting my motor number is if you have the same series (B) with the same pressure and GPMs. If my rusty brain remembers correctly, I'm 26 1/2 GPMs @ 3000 PSI. If you have the same series I can run out to the shop and get you the actual motor number. Just let me know.

DEWFPO,

I had to run out to the shop for something else so wrote down the motor number just in case.

Char-Lynn #105-1463-006

As I mentioned, if your flow and pressure are different this motor may not work for you. I spent lots of "phone time" with Char-lynn as well as Erskine before the switch.

My snowblower does work better in hi-flow than standard flow. But disappointingly so. It only throws the snow about 12-15 ft max at full rpm in high flow with dry, light snow.

My D is rated at 18.9 GPM standard flow and 27.9 GPM in High Flow @ 3,000 psi.

Thanks, DEWFPO

The Bobcat Blowers are actually Erskine designed as Bobcat bought Erskine then later shut them down. The Erskine employees later reopened themselves. The Bobcat dealer only has 3 or 4 motors they order for the Blowers while Erskine chooses from many different motors based on the particular tractor.

I would chat with your dealer and tell them you are less than happy and would like them to try a different motor and see what they say.

Good idea, will do.

I'm stunned to hear that your high flow TC/Blower combo is working better in low flow. My Blowers origionally did not meet my expectations and the dealer ended up changing out my blower motors to a different model motor. Made a world of difference. As previously posted, each blower is built to match the particular machine's pressure and GPMs. I suspect you are having a pressure/flow problem. The high flow (if properly matched) should well out perform the right motor in low flow mode.

You might also check your hydraulic filters, the large one under the bed near the rear axle in particular. Remove the filter and pour the fluid into a pan or container. Look for copper or brass colored flakes in the fluid. Just before discovering our drive motor issue last winter we were starting to see a reduction in performance (fan speed, blower performace, and road speed) just before the filters plugged.

with my c the 240 worked better in low flow (other than shorter throw distance). they changed out the motors to the higher torque/lower fan speed motor - same issue. i got a new d and from day 1 same issue - the blower works great in low flow except for less than optimal throw distance. never have rpm loss unless clogging blower going into a hill of snow. with high flow anything over 3mph and i loose power/rpm. exactly the same as with the c. my d came in late nov so i bet it had all of 25 hours on it when i first used the blower. since the blower motors were replaced and both the c and d had the same problem (both were tested at 3000psi and expected flow rates in low and high flow by dealer) i think the 240 is just too heavy for the tc - that is what erskine told me also. i am debating weather i want to change to the 200 or keep my like new 240. i see on the website the tc is no longer listed under the 240. i wish i could try a 200 out on my d to compare.

In the Snowblower O & P Manual (revised 01-08), it lists the 60" SB200 & the 72" SB240 as the only approved Snowblowers for the 5600T UTM. I run a 72" SB200. I'm not sure I understand the reason for the limitation in the manual.

I just found in the back of the manual, (as others have said) a list of several motor package (combinations) for the snowblower. I don't know what I've got on their but I'll have to dig around since they are covered in packed snow right now.

My dealer was a JD salesman and not an expert on Bobcats so it's possible he spec'd the wrong motor set for my application. We'll see what I find.

There are 6 sets listed and they are all rated at 2500-3000 psi.

Fan Motor : 105-1398
Auger Motor : 104-1027

Hydraulic Flow Range : 14.5-18 gpm
Fan Motor : 105-1399
Auger Motor : 104-1027

Hydraulic Flow Range : 16.5-21 gpm

Auger Motor : 104-1028

Hydraulic Flow Range : 21-26 gpm
