Put the new coupling in and all is good. Your theory must be accurate. The coupling stripped out completely yet the hydraulic pump shaft didn't suffer any damage.

Next to the grease fitting on the adjuster should be a bolt to release pressure. I used a block between the blade and front idler to push the front idler back. Next you want to find the track pin and position it 11:00 on rear sprocket and drive the pin out to break the track. The rest should be fair...

It would be nice to know if the undercarriage and blade are the same if so I'm not gaining anything. Heard as well they were overpowered for size ie. spin a lot. My undercarriage about 90% to trade up with a 400 machine with shoes half worn would probably move less dirt.

I pull my 350 with a 7 ton float f250 without any issue 400g would still be fine to go to 450 I'll need a better set up 10 ton float. I have the licensing to do it a 450g would be pushing it. Looking for some feedback as to who has operated and trailered all 3 of these machines to see if it's worth ...

Research I had done had the 400g at 12~13k lbs and a 450 at 14500 at least a 450c not sure about a G or H. It sounds like it would be worth trading up. The 350c had exceeded my expectations just find I'm running it hard at times trade up while it's still in good condition.

Have this 350c good machine just wondering if I'm gaining much by going to a 400g or 450 ? I need to keep under 14000lbs so I can float it. It will be a 5 to 8k investment. Just worried I might be disappointed with little gain or whether I'll be happy with the extra hp and ability of the machine. Wo...

Got it off with some heat and a pry bar. The coupling stripped out at the pump :shock: pump shaft looks okay. I ordered a replacement from john deere ag for about $50 less than Nortrax. It's still $95 dollars. Hopefully button it back up and it holds together. Is it common for this to happen ? All t...

It shows the 2 bolts. I'm going to try and grind 2 slots to fit pry bar in to see if I can get it to budge that way. I've been hitting it pretty hard not much luck. Thanks for response.

The hydraulic shaft stripped out at the coupling I had it apart to change fan belt not sure what happened? I removed the 2 bolts each side pump and it won't budge. Don't want to hit the pump to hard for risk of damaging it. There isn't 2 bolts that run through the pump housing that have to be remove...

Quick update on this thread. I purchased a hydraulic seat from TSC used the side brackets off the old seat and welded a couple flat bars across the bottom. Bolted the seat up and it works great. Definitely notice a difference on the back after a few hours of use. Hope someone might find this helpful.

Have this 350C the T handle hydraulic is pretty sloppy. Looks like a fair bit of work to re-shim or weld and re-drill all the linkages. Does anyone know of a place that could repair or possibly purchase a remanufactured unit and provide the old core at a reasonable price ? Just looking at options. I...

That worked, there was a C-clip on the shaft that had to be removed as well to get the yoke to slide forward.

How to get the pump to separate from the front x-member is still a mystery

Have this 350C thought I would change the fan belt while I have it somewhat apart. Realized the PTO shaft for the hydraulic pump is an obstacle. Figured the easiest way is to undo the 2 bolts holding the pump and slide it out to loop around the fan belt. Removed the 2 bolts and the pump does not wan...

I found a hydraulic repair shop that cut the line in half and attached a hose to the good side with a compression fitting. Good to go thanks for the replies.

Due to the number of bends I was hoping to find a factory type replacement. Sounds like I'll have to go this way. Thanks for the replies.
