Ok i ask this question with a very sick feeling in my gut .i had a oops today my JD 318 fell of my trailer at about 55 mph .it staid upright but now it wont move forward or reverse .ok transaxle prob trast how much is a rebuild and would a trans out of a 316 317 be the same as what is in it ? Very sick over this going to farm and home in morning to get better straps people learn from my mistake

I have a rear end out of 318 minus the pump and axles I'm looking to get rid of. Make me an offer.

 

[vinnie110]

You probably made deere burger out of the insides of the hydro pump. They don't like moving faster than walking speed without the engine running

 

[charms]

It's more likely the hydrostatic pump than the differential. Rebuild might be possible but very expensive. Best bet would be a good used pump or complete rear end. If you take the hydrostatic pump off you will be able to see if the rear end/differential is okay or not.

Shawn,

Like Cliff said, it has probably trashed the hydrostatic pump unit, not the differential. I bought a 430 that had this happen. It bent the hitch and cracked the axle mount too. I simply put a 318 pump on it and it runs great. 420 430 318 322 332 pumps all bolt right up. The only difference are the pressure reliefs on top of the unit. There are no relief buttons on the 420 and 430 since they already have a neutral for pushing them. You can just replace them with the reliefs from yours if you happen to buy one of those.

When you go to replace it, its a little easier to unbolt the rear end and slide the driveshaft off, than to take it off the engine. Once that's done, it's only a few bolts. Sorry to hear about the loss, but it could have been worse.

Ok deer burger ,good chance my question is is a 316 rear end and hydro pump the same on a 318 but also if rebuild possable will dealers still have parts what all interchanges looking to keep this 318 alive i do love her and i have the bug were can i find all this info also

 

[bearroberts]

Hey mike thanks but i am looking for a reserection if possible not ready to call her a loss maybe the hydro but the rest of the old girl is in tact . Are them the only pumps that will work or can we add a 316 to that listi do have a 316 and 317 just. Dont want to start taking parts off that wont work and waste my time

 

[jlang]

Shawn, the 316 with Onan will have the same rear end and pump. Not the Kohler powered 316 or 317.

Shawn-
You will need a hydro pump from any of the open frame 300 series or 420/430. This gives you a lot of different tractors with the same pump. As Cliff has said, you might be able to rebuild it since parts are still available but it will be expensive.

 

[bearroberts]

Ok found another 318 it is a litle older and lincages are not the same will it still work

 

[deereman84]

Shawn-
They are still the same pump and differential. You will just have to switch some linkages around.

 

[bearroberts]

Ok i found a older hydropump and were the linkages go the shafts are different the new one looks like it takes a rolepin in it and the one i took out is longer what linkages would i need
