After cleaning everything with a pressure washer i discovered two items of intrest.......A hydraulic line running to the left drive motor was preventing the right control stick from going to the neutral position (pinched below control lever).........The left control stick and lever was missing...

Brake is off......At first I thought that the brake was causing the issue, so I completely disengaged the brake. As soon as I pressure wash everything I will swap drive motors. Is there a "check valve" or "restrictor" in the drive motor? Thanks for the help.

Changed Hyd filter....Still no change.... If I move right stick forward and then move the left stick forward the "grinding and vibration" does not seem as bad. Still doesn't seem to have the power that it did and the hydraulics seem like there is a leak or that it is "by-passing" some where. I...

Tried your suggestion with no improvement. At first I was thinking that it may be the left drive motor.....BUT.......I don't think that that would effect the bucket movement.... Also checked to make sure brake wasn't sticking or dragging......This issue seems to have started when I adjusted the...

I have a 642B that I am having some issues with...At first the bobcat was driffting when in the neutral position, so I adjusted the steering to stop the drifting. Now when turning the bobcat the hydralic light comes on, the engine stalls and the bucket lacks the pwoer that it had. I have tried...

While using my 642b yesterday it was very sluggish, then completely quit. When trying to restart, the engine turned over fine but would not start. I pulled the #1 plug and checked for spark, there was none. Checked coil for spark with same results. I am thinking of replacing coil, points...

At the time the fluid leaked from the front of the reservoir I was traversing a very steep incline in reverse. All of the fluid moved to the front of the Bobcat. I don’t believe the reservoir is over filled, I will check to make sure. Thanks for the help. Always appreciated.

Thank you.......Great help.

I recently purchased a1990 642B bobcat. After adjusting a few things and replacing a few small parts the bobcat was ready to work. While using the unit to dig I noticed that oil was coming out of the front chain case cover. I guess it was not sealed the last time it was removed. I have a service...

Thank you........Great help. I found the sending unit hidden under intake manifold.

Thank you for your quick reply. Where would I find the sending unit for the coolant? I have looked over the engine and see nothing that looks like a sending unit. There is a "bolt/plug" in the head on the right side between the intake runners. That is the only thing I have seen.

I recently purchased a 1990 642B. I am fairly new to the forum and have already used some of the information from this site. I believe the machine has been “modified” by previous owners. There are NO gauges on this unit, only two lights, one for engine and one for hydraulics. I would like to...
