    Where to look up info about my bobcat 743 and drive chain question?

    Do I need to remove the whole top cover and pump assembly to relace axel seals on a 743? Its not a 743B so the hubs do not come off the axels. Any short cuts that may make this easier.

    743 crankcase pressure problem

    Yes wet liners come pretty easy just a screw type puller, dry liners need a puller usually hydraulic. This by physics will compress the bore. Even cylinders from Bobcat are semi finished. I have read many times that after market are no less quality than OE. The last engine V1702 I just had it...

    643 verses 743 engine wiring harness.

    Yes but I have found that they will say they are not but yet they are the same or close enough that they would work. Just wondering if any one has used one in place of. I see no reason why they would not. Electrically the only thing different is 3 glow pugs verses 4 but it only attaches at the...

    643 verses 743 engine wiring harness.

    I got a running 643 diesel Kubota 3 cyl engine and wiring harness with it. It came with a 643 bobcat minus everything on top of the tub. Also the drive motor were also gone. My question is basically I can see no reason the harness from this would not work on a 743 the only difference is 3...

    Replacement engine for an 843 Perkins 4-154

    My main concern is parts. I am capable of rebuilding it (I was a journeymen mechanic) but I do not want to tear it apart and find there are no parts sources. If I do a rebuild and the crankshaft main bearing are out by .005 but I cannot locate parts I have a real mess. As far as replacements I...

    Replacement engine for an 843 Perkins 4-154

    Its been over a year since I searched the forum for Perkins 4.154 in my 843. Has anything changed as far as parts? Any new sources I have low oil pressure about 10 psi with a pressure gauge hooked up. Engine runs fine just worried about the oil pressure. Any help for parts would be great.

    1989 632 screaming on turning not turning well - need help.

    I have had a 632 for 20 years. I love it. #1 it has to be full of good hydrolic oil, #2 it has to have a good hydrolic oil filter no clogged at all, #3 it needs to be run wide open. It will scream if you are not wide open. There is not that much HP there especially with a older motor. I do not...
