 Topic: Distributor shaft
Posted: 22 Mar 2024 at 6:57am |

I have a couple of Delco distributors from WD45s that the shaft is very loose due to rust. Is a new shaft available?

G'Mornin' Lonn!
Some mainshafts are available through older Delco dealers like myself. I have a few mainshafts in stock left, but like anything else you have to go by the Distributor number. The prices are pretty dang high though. Delco Remy isn't bashful with their pricing especially on discontinued or deleted parts. Depending how rusty they are, if its just surface rust where the bushing contact area can be polished, you can then mic the mainshaft, install an oversize bushing, and hone it to size. The unit is like new again. That's what I do on some customer Distributors that I can save... HTH Steve@B&B

Usually it's the bushing that wears, not the shaft. I'd bet dollars to buttons if you replace the bushing it'll be good to go. All replacement bushings for Delco distributors have undersize bores that have to be polished/reamed to size anyway, so you can account for a bit of shaft wear anyway. You have to be a little careful when pressing the bushing out/in as it's a tight interference fit: you need to support the body inside the housing, not on the rim the cap sits on or it'll crack the body. But replacing the bushing is something you can do yourself: Even polishing the bore to size. I used to take them to a machine shop to be reamed to match the shaft, but now I just use a piece of fine emery cloth in a slotted shaft in a drill chuck to polish it to fit the shaft: I think I get at least as good a fit as I did when going to a machine shop.

Thanks for the replies. After moving parts around to get nice distributors I ended up with two that need lots of help. One is a D17 that is very loose and a very worn gear. The other has a very rusted shaft. The bushing is nice. They are back on the shelf for parts. I suspect more parts tractors will show up in the yard giving me more parts to choose from.
