1. Chelsea 1" spline kit 328591-129X

2. QCC pump 1"-15T CPC 1049 CPC 030-R-2-AF-BC

& what's the delivery time?

I need to change mine, it's starting to make noises.

The new PTO is fine. About an ounce a run. Screw it, unless the weep turns into a leak I'll pull the pump and have my local guy change the shaft seal on the next fluid and filter change.......kinda disappointed in the company that now builds these pumps new. Most hydraulic shops can rebuild old pumps but only one company now build the pumps new..........

My leak was at the grease fitting on the shaft of the PTO. If you're leaking hydraulic fluid from the pump I'd be a little concerned of hydraulic fluid filling the cavity which joins the PTO to the Pump and eventually overwhelming the seal at the PTO which would mean hydraulic fluid in the transmission.

SOOO, with the monsoon rains subsiding, I finally got to get under the bus to look at the pump "weep".

Observations:
- It truly is a weep, no noticeable loss of fluid, still at the same tank level
- The cavity is empty and stays empty??? Huh!!! How do I know that, well there is an inspection "port" / line hole not used in the back of the PTO flange you must put a plug in. I removed the plug, used a dental mirror and high powered flashlight. I can see all the way into the cavity and the shaft splines not in the pump, cavity is dry
- The weep oozes out between the PTO Flange and Pump, where it bolts up.

I will FIX this when I get home in the fall as the next walk about will be a very long one.

Questions:
Does the wet spline conversion have a different PTO flange from the grease version? to better seal the PTO and Pump cavity???????

If you convert to wet spline and the pump seal eventually lets go as other owners plus myself reported, are you now mixing hydraulic fluid and pumping it into the transmission as David suggested????

I am not berating anyone's decisions on how to upgrade the PTO/Pump...We are all adults and in the end we call our own ball and live with our decisions. I just want to report what I see going on in my new grease setup.......... new pump AND new PTO
FWIW my 18 year old no grease, no wet setup NEVER leaked a drop of either fluid and the splines would have lasted another 3-4 years...They sure don't SPEC and make things like they used to!!!!!

When switching from a greasable PTO to a wet spline; what happens to the grease in the PTO? It gets mixed with the transmission fluid;doesn't it? I doubt that it is enough to hurt anything but it may be prudent to flush out the grease by removing the end cap (the one with the grease fitting) for access. Also the grease fitting should be removed and the hole plugged or replace with a new end cap with no holes.

Thanks for clarifying the process for upgrading a SAE B (7/8"-13T) PTO to a wet splined SAE BB (1.0"-15T) PTO. I'm on your heels! This upgrade is on my short list.

Concerning the use of flex hose in place of the steel U-Pipe. From our Document Library, the Chelsea 267 PTO Installation documentation, page 3, has this to say:

Chelsea strongly recommends the use of pump supports (Support Brackets) in all applications.
P.T.O. warranty will be void if a pump bracket is not used when:
1) The combined weight of pump, fittings and hose exceed 40 pounds [18.14 kg].
2) The combined length of the P.T.O. and pump is 18 inches [45.72 cm] or more from the P.T.O.
centerline to the end of the pump.

It's been a while, but I think our combined PTO + Pump length is shorter than 18 inches and I think we come in at less than 40 lbs. If not, then the steel flex pipe does serve as a support of sorts. (It's better than nothing)!

Thanks, David,

I will get the part #'s and their cost together when I know what they are for sure and post the info here. I just don't have it broken out yet.

The problem with the steel u-line is the coupling nuts have bad threads.
A new steel U-line pipe would probably have to be custom made. The present u-line configuration does include a length of flexible hose.

I haven't measured it but I think it is less than 18"s but not much less. It may also be that the 1" pump is longer than the 7/8", I don't know that it is tho. I wouldn't be surprised if the weight exceeds 40#s. There may be a convenient way to add some bracing, I'll speak to Rolando about Chelsea's recommendations. I wouldn't want the weight to fatigue the bolts and let the assembly fall off. Yikes!
