The Char-Lynn PTO pump that I have is a good pump and I have cleaned and painted it to the max, installed a new shaft seal. However, there is a leak at the shaft. Some of it may be at the tank seal, but it leaks more when the shaft is spinning. I know the company does not sell parts anymore but is there anyone out there with some good answers or sources. I need a really good seal. 1-1/4 shaft and 1-13/16 bore and the bore could possibly be machined larger. Thanks for any help here. ---Derrol in Texas---

Is there a groove worn in the shaft where the seal runs? If there is a groove then check if you can re-position the seal along the shaft to miss the groove. A double-lipped seal might contact the shaft in a new spot. Worst case for a grooved shaft you can install a "Speedi-Sleeve" (from Chicago Rawhide?) over the groove, about $20-$30 at NAPA, or any bearing supplier.

Maybe the new seal was damaged during installation or put in backwards.

Good luck.

Sounds like you have the correct info to go to a bearing dealer and ask for the lip seal for that size you stated.. goodluck ! chuck

Thanks Guys, I did not see anything wrong with the shaft, and I did install a new double lipped seal. But something is not quite right, so I will try again. I think there is room for a double lip and a single lip seal in the bore. I thought there might be a better seal system that I am not aware of.---Derrol in Texas---

Well I tore down the Char-Lynn pump again today and found a problem with the tank seal where it seals around the shaft against the pump. Didn't have the fat O-ring that I needed so I manufactured a brass spacer and gasket for the O-ring to set in, works good so far. The seal on the shaft doesn't hold pressure because there is a relief hole drilled between the brass bushing (inside the pump) and the seal. I did enlarge it to the next size, 13/64". Put it all together and haven't lost a drop of oil. Did some plowing for the first time since I went to Kansas and got the 4-bottom Case plow. Been dry here and that ground is hard and it comes up in big chunks. But the pump works fine. ---Derrol in Texas---
