Nice find. I would like to see some pics of how the steering cylinder is tied into the system.

The orbital valve is tied into the hydro pump and then from the orbital to the steering cylinder.

A little more work today after work.... Had a meeting after work so I couldn't run to my favorite machine supply store (Hokel in Ames,Ia) but the local welding shop was open so I got some steel to build a new chain cover and noticed on the wall they had sprockets! So I over paid for everything because I needed it NOW! uploadfromtaptalk1397003710773.jpg uploadfromtaptalk1397003725385.jpg uploadfromtaptalk1397003737683.jpg uploadfromtaptalk1397003753370.jpg
As you can see the old sprocket has seen better days! My 4850 tiller manual shows a tensioner sprocket but mine doesn't have one, it just had nylon pads that attached to the plastic cover, BOO!

Lookin good!!  My 4250 just has the teflon/nylon pads for tension too.  There's one on the top that keeps the chain from flopping,and then the spring loaded curved on on bottom that keeps tension.

Nice cover & good repair.  You might want to add a peep hole directly over the chain so you can use spray lube handily.  A flip cap would be cool.

Hey there is not a lot to the sprocket tensioner just a bolt, spacer, sprocket, a couple nuts and washers and cut yourself a slot for it to slide up and down to set the tension. Maybe I will take a couple pics so you can see what it looks like tomorrow

You mean "4850"... Sorry I couldn't pass up the opportunity.

I added my tensioner sprocket a few weeks ago, had to modify my cover too! I couldn't find a sprocket any smaller than 12t locally and didn't really want to lengthen the chain to get the sprocket down further, so the next best thing was to add a hump to the cover!

The MF4250 tiller is 42" cut, and drives off a chain system in the center of the tine gang.

Yeah, still kindof too much of a sore spot to be funny at this point!  I should've pushed harder to get my money back, but I hate pursuing things legally.

 

In better news, I really like what you did using the sprocket for the tensioner, vs a teflon pad.  Is the sprocket spring tensioned?

No it's just static pressure.I figure by the time it loosens up where the tensioner isn't working it would be time for a new chain anyway...
