1655 2-70 Pencil Injectors

Hello all, I have two bad pencil injectors on my 1655. It's a late model (1975). I know the Stanadyne part # on the injectors is 20498. The guy doing my injection pump said I should check and see if any of the John Deere pencils injectors cross reference to this application as the John Deere pencil injectors can usually be had a lot cheaper (usually online). I haven't been able to find a cross reference the Waukesha 283 to any John Deere. Any help?
I found the Waukesha application injector for a about $50 each and many of the JDs can be had for about $25 each. Thanks.
 
Nope, JD 20494 won't fit. Also, be aware the prices you found I'll bet are NOT for original Stanadyne injectors, but aftermarket. Last I knew the Waukesha injectors from Stanadyne were 100-110 each, JD were 60-70 each. While SOME aftermarket seem OK, I've seen some start leaking after a few hours use at the banjo joint, making them useless.
 

When I picked up the parts for my pump my local Stanadyne dealer wanted $91 each. They didn't push them on me because even they thought that was a high price for pencils.
 
What helps with cost pricing is probable use needed, JD injectors are priced less because there are so many engines out that could need them at some time. MM, Case, Oliver pencil injectors are always more due to much less demand..
 

Yeah, I have no doubt that's the case. I would have to think there's another exact same spec injector though- especially with all the Case/Deere equipment still running around out there.
 
I've bought injectors from Spencer Diesel probably not the cheapest but the injectors have been great and the people on the phone know what they are talking about
 
So for $150.00 you are going to risk roasting a piston because the pattern shape, or orientation isn't correct?
 
P.S. if you buy aftermarket injectors make them test them for pop off pressure and pattern before you take them home. At one of my prior employers (for those who know me, not the last one but the one before) we would get in batches of 500 or 1000, and get about 1% that didn't pop at the correct pressure, &/or have a bad pattern.
 


No, I'm just hoping to save some money by buying the same part under a different part #. I don't have a lot of $$ into the tractor and I'd like to keep it that way.

I'll pop off all the injectors again before install.
 
List price is 96.10.. I don't pay list BUT> w/ shipping to me, then to you, we're above list price.
& no cross listed.. either thru Stanadyne or my supplier.
 

Thanks.... yes, they're looking very specific. Just to confirm, the Oliver part number I need is 165857AS correct? Is the same part number is listed for the 310 engine as well? The Stanadyne number 20498 is specific to the 283...
 
From the Stanadyne listing, 20497 is for the 310 turbo, four holes, .0116, 3200 service PSI. 20498 is for the 283, four holes, .0096, 2600 PSI service setting. 20499 is for the 310 no turbo, four holes,.0106, 3000 PSI service setting. 20497 is 69603, 20498 is 69602, 20499 is 177033. Agco numbers may supersede..
 
Thanks. Just thought I'd update this thread...

So the part number for the injector (Stanadyne 20498) is 164453AS. I found one aftermarket manufacturer, Reliance, they're about $50 + core. I called around to some fuel injection shops and they all said, "Pencils, no problem, we have lots of those," only to give them the Stanadyne number and they go, "Wow, those are really expensive" or "Yeah, we can't get those," or "Huh, these are in what tractor?"

Regardless, Mylex International (had two new ones in stock- I didn't ask the price) was very helpful and they're going to recondition them all @ $30/each, which is good enough for me and I'll get to keep the original injectors. Just thought I'd share.
