At me the nearest dealer in native land in 750 km, and in Russia of 350 km. Therefore I ask somebody can tell from what material seal is made? And freely it enters in balance ring?
The nearest dealer in Chelyabinsk has told that can offer only the new engine. I have made consolidation from ftoroplast, At once the problem with movement has disappeared, but through 2 business hours there were jerks (Sharp intervals) in movement. After dismantling of the engine I have found out seal the equal. Ftoroplast very much elastic material.

Yes we could just order the seal. You can order it online and have it shipped. I found a place in Australia that sells them http://www.hydraulicspecialties.com.au/products/all-products?keyword=6961-000

I never thought that seal really did anything...... You should be able to buy a complete seal kit from http://loaderpartssource.com if you can't just get the seal you need.

Nester1, I work at Loader Parts Source Inc. and I was reading this and when I saw your post I double checked. We do have the seal kit that you are looking for, but we just did not have it on the website. I am working to get it up now. It should be there sometime tomorrow.

This has nothing to do with the Bobcat 743 per se, sorry. @ cnord by the way, thanks for such a great site, I use loaderpartssource and a smimlar site mwedirect.com quite often to find what I need, always nice to find sites that let you shop by your machine make and model. Showing me the parts I need for my machine instead of a million different options makes my life so much easier. keep up the great work. Shawn Hill

Call us or email us and ask for James 1-866-573-3659 or [email protected], He has the information in regards to the seal kit you need. It is different than the one for the 600 series machines. It includes every seal you need to rebuild that drive motor.

Similar shuttle valve is perfectly in order, except for the small flutes rubbed with springs on shuttles from outer side.

But I have found out internal seal damaged with one edge.

There can be it a problem? The second motor didn't assort still. Whether I can not to wait the original, to pick up or turn from a caprolactam the similar?
After replacement of consolidations motors on force work ок, but at slow inclusion of movement of left-hand side back, at first occurs nothing, and then movement begins with proslipping of wheels sometimes. I think a problem in deterioration of the transfer valve of the motor. It is possible to buy this piston and poppets with springs separately? I translate of the internet translator with the help. How to write in the order?

Nobody will prompt where I can buy shuttles valve on my drive motor ? After replacement of consolidations force at motors well, but the sharp beginning on the left side remains, I think the reason in worn out shuttles valve .

Do I have to have that tool to remove the bronze filter ? Also, Do I really have to drain the tank? That didn't work for me today.

I used pointy nosed pliers. Oil will flow out, you are better off draining all the oil you can before starting. If you have a helper, they can plug it with a finger while you go clean or replace the filter.
