Hi Gazza, I was wondering how you went with your n844lt? I have just bought a L175 with a blown engine. The head has been removed on this one and there are score marks on the bores. Any hints and tips would be greatly appreciated. Regards John

Thanks Tazza, couldn't have done it without the help of the forum. It probably took me about a month to do. Mostly worked on it in my spare time. There is definitely a huge difference in power now. I had to adjust the pressure relief on the control valve because it was stalling the engine the...

After a couple weeks of playing around with the 543, I've finally managed to get it to do what I want.. The left side drive motor is still a bit weak, but that will have to wait till next time.. Ended up stripping and cleaning down the hydro motors, replaced the old D950 with a D1105, and a lot...

Hi, I could be totally wrong about this, but could it be from one of the bolt holes for the manifold? Ive found on some of my kubota engines that the bolt holes actually go into coolant galleries. This is more so for the exhaust manifold bolts..

Have you tried www.bobcatpartsonline.com/bobcat ? I'd suggest using internet Explorer to open up the page.. online parts catalogue for bobcats, Has illustrations and parts breakdown, so you will see what parts and seals go where.. Hope this helps!

Hi Tazza, yes, I have the 2 hydraulic drive pumps and the gear pump on the table. I have since competely stripped down all pumps to inspect for damage and wear.. This is how I came to see the extensive damage inside the gear pump. According to Machinist's info, I think i might try and fit the...

Thanks OldMachinist for the info, it's exactly what i was looking for! This is what i'm up against at the moment!

After sitting outside for a while, i decided to bring the bobcat in and pull it apart and repair the multitude of problems that ive had since i bought it. after searching the net for a while, i havent been able to find the specifications for the hydraulic gear pump. bobcatpartsonline.com lists...

hi tazza, yeah i posted about the problem with my d950 about 2 weeks ago. the bottom of the bore itself was warped and had excessive ovality. What we found was that the liners themselves hadnt worn at the bottom, but that the block had warped. We ended up putting it all back together with the...

Hi Tazza, thats pretty much the info that i was after. Thanks. I figured that with a higher torque engine, i wouldnt have to hold the revs at a higher range. In doing so, i thought that pump flow may not be as high and the hydraulics may be slightly slower moving, but the engine itself shouldnt...

Hi All. I have a 543 with a Kubota 3 cylinder D950. According to the WSM, the D950 has 20Hp at 3000rpm with a maximum torque of 55Nm at 1800rpm. The engine that I am looking to replace it with is a 2 cylinder diesel with 30hp at 2400rpm and a max torque of 107.5Nm at 1680rpm. I would like to...

Hi all, Im looking for a bit of help at the moment. My father recently bought a 543 off ebay in a rush. The machine had no hour meter, the VIN plate had been painted over and the previous owner had told us that it was a 1990 model with no oil leaks and in fine condition. Waited over a week...
