I hope for your sake that you didn't have happen what happened to me (Perkins 4-108). Turned out the crank was broken in two places and it still ran. Didn't happen right away but I'm convinced it was due to using starting fluid and I never will again. Now I use heat gun in intake manifold and...

A falling bucket when the unit is not running is not indicative of a leak past the piston. Assuming the lift is enacted by hydraulic oil entering the side of the cylinder opposite the rod, consider this: every inch worth of oil on the non-rod side would occupy more than an inch on the rod side...

The fact that the hydrostatic drive works well probably doesn't mean a thing. On my 825, there are two pumps, one for each set of drive wheels and a third for the bucket operations, pointing to the fact that the pumps are separate.

Mark I have exactly your machine (see my photo; restored 2005). My machine does not have the aforementioned fuel valve and I don't believe it ever did. The engine is shut by pulling the throttle lever all the way back which changes the variable displacement injection pump's output to zero. Are...

On my old 825, there are "levers" on each side that disengages the motor from the gearing inside the chain case, allowing it to roll freely. My little JD lawn tractor also has a "knob" that pulls out under the seat for the same purpose. My Gehl excavator has no such release. I can't believe the...

I've never used a skid steer with hand operated bucket and perhaps because mine is older technology (Bobcat 825) but I find it very difficult to precisely control with my feet. I will sometimes reach down and operate the pedal with my hand if I need to do fine grading. I have a mini-excavator...

Bobcat 825

Regarding engine swaps in 600 series, I put a VW Beetle air-cooled motor in mine years ago. It stuck out the back because it wouldn't fit between the housings. I had a Baja header system on it and I drove the hydraulic pump off the back of the motor. Since the crank was running front to back and...

My Perkins 4-108 has works well but there have been issues. The crankshaft oil seal at the accessory end of the motor won't stop leaking, even after replacing the seal several times and even sleeving the journal on the crank. Recently I read in a marine forum that it could be due to the way this...

I haven't figured out how to put picture in my reply so I created an album in the Media-Photos section under imtools 825.------------------I haven't yet painted the tray nor made a permanent holdown but so far, it is much more convenient and I have a big battery that diesels need in cold...

My 825, rebuilt 2005

The battery location on the 825 is really lousy, both for replacing it and for jump starts. I ended up making a bracket for it that puts it above the wheels. I now use a 1000 amp hour battery-really BIG! and accessible. You should not use starter fluid on most diesels. The Bobcat manual strongly...
