Ditch Witch C99

[Whattheheld]

I am needing to get an air filter element for the Ditch Witch C99. The one I have is the round dry element filter and it is totally shot. Cant seem to find any place that sells them. I would appreciate any information.

Were you able to find a replacement air filter? I was striking out today

Joining the club here. Just pulled the old C99 out of the back 40 to see if I can get it running. Starting with gas, spark plug, air filter, and pull rope and we will go from there

You might try calling Ditch Witch about the air filter. Their motto is, "Every part for every machine ever"

I think I sent the manuals a bit ago. Hopefully you can find a part number in there that you can cross reference. In the past I have had to take a filter to a parts store and have them look through all the boxes. These days I wonder if you could find a filter maker's web site that lists the dimensions of all their filters and come up with one.

Let us know how it all turns out.

Got the spark plug swapped out and some gas in it but couldn’t get it to turn over. Spark plug cable seems to have iffy continuity and I don’t see a spark at the plug so I will try to replace the connector to see if that does it.

A big thanks to Dave for the information!

This past weekend I changed the tires on my C99 and cleaned up the gear selector. It wasn't selected the forward gear, and I found a broken spring along with being jammed full of dirt. Here is a summary.

After a good power washing:

After removing the locking collars and a few snap rings, the gear box slides off the shaft. If I were to do this again, I wouldn't have taken the whole axle off, I would have removed the drive chain, jacked up the trencher on the drive side, removed the wheel, then remove the gear box. It would have saved a lot of time.

Here a found the broken flat spring

someone decided to weld up this box. I didn't weld it back when I put it together, so I hope it holds with just the two bolts.

Here you can see the dirt jamming the gear selector. The power washing didn't get rid of this dirt.

I welded the spring back together. I didn't think it would work, but I gave it a try.

Here is the selector back together.

Here is a video of the selector. Notice how these tabs will engage when the selector is all the way to one side and in the middle neither tab will engage.

And just because I liked how these wheels turned out:

I hope this helps some c99 owners out there!

Nice job, I have a c4 that uses the same gearbox nice to have an idea of how it is supposed to be.

I would be happy to send them but I will need an email address that can accept file attachm

Would love the same manuals at biggermacdaddy@yahoo.com thanks

Hey Barry, great job on the pics and great job in general! I think the gear boxes are all welded from the factory. Surprising to me but maybe DW figures they will never break. Did Dave send you the manuals yet? If not, I can get them off to you.

Happy trenching and wrenching,

Gary
