I have replaced them here in the shop, did several of them when people started using the new road fuel, it caused the old style o-rings to swell up and then they would cut-up when the shaft turned, I removed the pump and carfully took the cover off and pulled the shaft, wasn't to bad to do..

Just needs two o-rings and two teflon backup washers - as long as it's a DB/JDB pump and not a C pump.

 

[travz500]

i believe its a DB style without going out in the shop to look

 

[travz500]

where can i get the parts to repair?

Has to be a DB pump unless someone has replaced the engine with a 210,000 and up serial number. Be sure to also install a couple nylon dust seals on the throttle shaft. Its especially important on an older pump.Any Deere dealer should be able to furnish the o-rings. Maybe the seals too. Also a good time to look for black looking bits of the governor seal while you have the pump cover off. If you find any, you might as well pull the pump and have it rebuilt. External fuel leaks are usually a good indicator of the pump condition.

I don't think Deere has sold any pump parts in years. A complete injection pump seal kit that comes with all o-rings, governor weight retainer, delivery valve stop, and shaft umbrella seals can be bought for around $15 from many other sources.

They should have the individual parts. Might have to match them up. I should have an old parts book somewhere. Used to have them all memorized, but time passes us by John.

I still have all the old parts books. Years back, we bought all our Standyne parts though Deere under Deere part numbers. It was cheaper. But, then Deere stopped selling the parts.

Now, there are several aftermarket diesel companies selling parts cheaper then ever and I've had no problems with any of the parts. Spaco from Italy is one of the major places.

Part #s from Deere used to be - T11915 (shaft o-rings) and T15720 (shaft teflon washers).

The original complete kit from Deere used to be AR34612 (no longer available). Standyne # for the same kit is 24371. You can buy the complete kit from Spaco as U24371 for around $14. US Diesel in Fort Worth Texas is the Spaco dealer I use.
