On other Bobcats I have had, over the years, every time I heard this insane growling noise, it was always worn out hydro pumps. But in this case, there is NO lack of power in any direction - in fact has more drive power than I ever expected a 642B would have. Changed hydraulic filter in rear...

Have a 642B that I recently purchased. Stored inside in closed-in garage, supposedly for 2 years. Runs good - loader arms and bucket tilt work perfectly. Hydrostatics are strong - almost like they are getting over the recommended maximum 4000 psi of drive pressure. You can't control this...

Sorry guys, been off this forum so long that I didn't see "Bobcat" up at the top. Who could miss it, right? Anyhow, can't find an "Edit" button to be able to move this post, so I guess I'll just have to leave it here, until one of the "Mods" do it. Thanks John

Hi guys, Been off the forum for quite awhile, after I sold my last Bobcat. But, once you get "skidsteeritis" you have to have another one! So, in rambling around, I came across a Ford CL35. Owner says it has a Wisconsin engine, but the little bit of info I have found so far, says it would be a...

Actually, guys, I mistakenly quoted the service manual as showing a charge pressure of 85#'s, when, after rereading it this am, I find that for this particular machine, it should be 95 - 115#'s. I do recall that it maintained this 100#'s plus during hard operation yesterday, so at least that is...

For those interested, I hopefully have got the bottom of the problem - just not sure how I got there! I removed the charge pressure switch and put a run tee in, screwed the switch back in and reconnected the wires. I then had a 4' hyd. hose made up which would route up through where the wiring...

Tazza, I ordered a manual on this machine (more about that, later) and it shows, if I'm reading the schematics correctly, that the wires from the temp sending unit and the charge pressure unit are tied together, going to the light. The light is described as a "Transmission" light. Seems somewhat...

Drive power seems to be unaffected, as it will spin the wheels if it can't move what's in front of it. Lift arms/tilt seem to have sufficient power as well. Several months ago, just motoring around the shop, the light came on a few times, briefly and then went back off. After starting this...

Thanks for the reply, Tazza. I talked with a Bobcat service tech today, and he seemed to think that it indicated the charge pressure, and further, that it also controlled the hour meter. Incidentally, the hour meter quit working about the same time the light problem showed up, but I attributed...

Alright, time for a dumb question. Does the red warning light, on the right hand side, indicate a restriction in the hydro circuit or extremely high hydro oil temperature????? Or, something else entirely ? Further, if this is the case, is it tied into a shutdown system which would stop the...

Just a brief update to let everyone know my findings. The hydro oil leak was a result of a broke dipstick tube - poor system, if you ask me, to solder a dipstick tube into the side of the hydro tank. Apparently a limb had hit it and broke it loose. Not wanting to drain and remove tank for...

Thanks for the replies, guys. No, we're definitely dealing with two seperate problems. The engine has not lost a drop since it's last oil/filter change (Delo10w30) and as I indicated, I had just checked the oil before startup, yesterday AM, and then again after lunch. Dead on the full mark...

Hi guys, Been off the board for awhile. Have been running the 742 pretty hard this week. Checking engine/hydro oil twice daily. No problems, until this afternoon. Checked both and they were right on the full marks. After about 3 hours of running, I noticed that a good bit of oil had come out of...

Thanks for the replies. Yes, the red oil is in the hydraulics, not the engine. And I did say, in my original post, that the hole was in the engine block. As to seeing an engine in my future, that's debatable, as I could just TIG weld this hole up and rebuild the engine. I don't consider Northern...

Hi guys, Acquired a Bobcat Farmboy, which according to the dealers I've talked to : (a) does not exist (b) is about 40 years old (c) is not a Bobcat, I just think it is. Even called the factory in North Dakota and the brilliant woman who was supposed be a Tech said I should just consult the...
