    1995 Bobcat 743B Engine Knock

    Where are you located in Ct ? I’m here also. It doesn’t sound bad to me these engines do kinda have that sound and I can also here the lose clamp or something. But I don’t hear a rod bearing that’s for sure. Maybe a main bearing but I don’t think so either.

    1995 Bobcat 743B Engine Knock

    My 743b that is ready for a rebuild doesn't sound much different . Really hard to start this machine at this point gotta really ride the starter even on warm days. Trying to get through this one job with it before a rebuild / replace engine ill either rebuild my 1702 or get a 1902 or 2203 for...

    How do i disengage wheels from engine in order to pull a bobcat machine

    I had a situation where I couldn’t get mine started not to long ago and I hooked my dodge 3500 diesel to it and pulled it across the yard in reverse the wheels were locked. Spun it around and it rolled forward with ease. I don’t know why one direction was different than the other. It’ll...

    Yes to testing voltage . No to testing length of time But you did see the picture of it pouring blow by out of the breather tube right?

    And if it’s a cold day I end up using the grid heater. It is a really big plus having that thing there. It works great. And it will stay on when I rebuild the engine shoulda had it in the first place on the IDi engines in My opinion.

    I saw that written online somewhere but I also talked w 3 people w v2203 DI engines that were in 743bs and they were really happy. And they’ve been I a while. They also said , no glow plugs needed and there’s weren’t even rebuilt v2203s

    743b issues electrical and other

    I don't see how stuck valves could cause that , it would go out the exhaust or the intake (which I do think it pops back into the intake sometimes.) But I think the only way you're getting that amount of blow by is w really bad bores/rings. Did you see that pic of the blow by? It's like...

    No because I didn’t have a 8 mm adaptor and I was pretty sure based on blow by that it was toast. So the blow by kinda gave it away IMO

Wanted to see if it would stay running. It ran for a good 2 hours . Next day started cold on glow plugs alone no...

    743b issues electrical and other

    Here's the blow by, I actually did a trick we leaned worked do. Race cars and misted some water into the intake (fine mist) and it cleaned up the blow by a bit, it cleans carbon off The pistons. So it's better than this picture and the second day started w just glow plugs but it runs rough when...
