PTO Wet Kit

Yahoo Message Number: 61598
I had the PTO wet kit installed this winter. Now, I am experiencing a transmission fluid leak at the point where the PTO interfaces with the Hydraulic pump. I have lost approximately 2 quarts of transmission fluid since 4/30/2010 during which time I have driven the coach 3,000 miles. I am currently in Pueblo, CO. I'm not mechanically inclined. What is my solution and to what type of shop should I try and go to get the work done. There is a Stewart & Stevenson shop in Pueblo. Can they do this? Other suggestions in this general geographic area would also be appreciated.

Had the same problem. Added a second Spicer PTO gasket to the first one and leak stopped. I have a feeling the splines are bottoming out, keeping the bolts from pulling as tight as they should to put enough pressure on a single gasket to stop leakage. Be sure and have the thick, stock gasket used. Long story on this, but my experience leads me to believe this may be the base of your problem, and perhaps what has lead to so much spine wear. If the splines are not perfectly tight and in alignment, they will wallow and wear faster. Gaskets are, most likely, special order items, not in stock in most places. It is a simple two bolt install. May want to start with two new gaskets. The old one maybe damaged if it has many miles on it.

Brian:

I installed my own wet kit and it had a minor leak until all the bolts were torqued correctly. You should have an owners manual for the Chelsea PTO in your literature with all the torque values, if not one can be downloaded from the Chelsea website. Any repair shop worth its salt with a torque wrench can tighten up everything and stop the leak.
If the problem as a poor installation involving something like a missing gasket it still isn't rocket science. The PTO is probably one of the simplest systems on your coach. An Allison transmission shop should be able to diagnose and fix the problem with little problem. If gaskets are needed Chelsea has them.
This sounds like one of those adventures inherent to owning an RV. Relax, grin and bear it.
Do you belong to Coach Net or any of the roadside assistance clubs/organizations? If so give them a call for a referral to a qualified shop. If you don't belong I think you should consider joining. Coach Net even got my dummy locked-the-keys-in-the-car situation covered - their program covers everything you drive not just the RV. I have used them twice for service problem referrals while on the road. Each one was a fair, fast experience. You could even call them, join on the spot and get your referral. 877-797-7160 I get nothing for referring you, just passing on something we have found extremely useful.

Bob,

Can you provide a link to the Chelsea PTO literature on their website? I don't have any literature among those provided to me by CC at delivery.

It is a small booklet. I am going to send you what documentation I have but from my other e-mail account as putting attachments to messages in Yahoo is a pain.

Wait one please.

I've just finished reviewing PTO 101 and PTO 101a for the umpteenth time, and can't find the information I need. Does anyone know the part number of the gasket(s) that fit between the PTO and the hydraulic pump? I saw the part number for the gasket between the PTO and the Allison Transmission, but not for the one between the PTO and the hydraulic pump. Does anyone know that part number?

Thanks,

Brian Davis

Could anyone who has done their own conversion offer encouragement or advise against attempting the job for one with a reasonable degree of mechanical skills? Are there any special tools required? Thanks.

Jimmien,

You can do the job yourself. It is a little like changing a starter motor.
It will help if you have a ratcheting strap or two to secure the pumps to the side of the transmission once they are loosened from the PTO.
It also helps to have a swivel ratchet where the head of the ratchet can be rotated side to side on the handle - Harbor Freight has them. This helps get to the bolts on the top and back side of the PTO to Pump bolts.
A set of curved closed end wrenches also helps to get to these bolts but the ratchet is a lot easier and faster.
One of the forum members made a set of pictures of the job two or three years ago and these can help give you an idea of what you need to do.

I looked under my coach several times to get my nerve up. After having read the warnings on this site I was concerned for my safety as well as the potential of more damage being done if I drove to a repair facility. I finally decided to jump in and in the end found the job to be easier than replacing a clutch in a 4x4 pickup.
It's really not that bad.

I installed the PTO wet kit about two years ago. This is not a terribly difficult job. Basis mechanical skills are needed. I would rate it as a one man all day job. The tips already given are good. Don't forget to checking the condition of the male spline coming out of the pump.
Good Luck, RJ 2005 Inspire #51264

Look for document "PTO-101a.pdf" in the files section of this website. It contains information about looking for the PTO and determining if it is WET or DRY. It contains great info, pictures, and a link to pictures of a torn-down PTO.

After receiving encouragement from other owners, I ordered the kit and plunged in. I found it a bit more difficult than some of the descriptions, but since retirees have lots of time, I plodded instead of hurrying through the process. I am sooo glad I didn't wait as mine was very worn. The coach has 33000 mi. If you haven't verified your PTO is wet I recommend you do ASAP' A failure could really ruin your day.

I inspected my dry PTO at 32k. Link to slide show is here: http://muniac.smugmug.com/photos/swfpopup.mg?AlbumID=18975398&AlbumKey=kh2TZb I cleaned and repacked the spline with synthetic grease. Luckily all looked fine. I'll probably do another inspection this Spring. Pictures will be taken, of course. I think this is yet another maintenance item that needs attention constantly. I have no plans at this time to install a lubrication system.

I'm curious if anyone (besides me) has concerns about circulating unfiltered transmission fluid back through the transmission that might contain metal filings?? If the kit has a filter than this is a moot point. Safe travels to one and all.

Scott,

I believe the fan/power steering hydraulic system is isolated from the transmission. The 2 fluids do not come in contact with one another. Therefore, there is no chance that the PTO fluid could contaminate the transmission fluid.
I'm pretty sure this is the case on my coach at least.

Scott,

I have no concerns about non-filtered oil in the transmission. Actually all the trans fluid is unfiltered until the trans oil pump picks it up and runs it through the two (Allison) filters before pumping it back into the transmission working parts. The metal filings from the PTO would be very small compared to what is coming for the transmission itself. Not only metal filings but large pieces of clutch material also. The majority of the PTO is oil lubricated already. Only the splines between the PTO and hydraulic oil pumps is not lubed originally. Wouldn't expect to see any wear when the splines have constant lubrication.
I replaced my PTO with the wet kit myself and no longer have any worries in that area.

Well, the transmission has its own internal filters that trap contaminants from any location in the transmission. Allison did provide the PTO port, so I would think that they have engineered the transmission with the assumption that a PTO may be fitted.

My 2007 CC Tribute 260, 40', single axel coach is in perfect condition with 35K miles. Everything has been serviced by Kenworth. We are leaving in 10 days for a 4 month trip...KY->Dallas-> Venice, Fl ->KY. I do not know if my CC has a dry or wet PTO? CC tech told me what to look for under the coach but nothing under my coach looks like what he described. Does anyone know about the Tribute? I have a C-9 400 HP CAT & Allison Trans. Do I need to try to have it checked/fixed to Wet if necessary? Do I have time??

You have a dry pto. I have the 2008 Tribute 260, and mine also is dry. That said, I don't know all of the details, but it is my understanding that the pto that we have is a different and more heavy duty model than previous years. I have, at the advice of the manufacture, pulled and lubed my with the provided grease, and it is still going well, but I only have 25,000 miles on it.

Scott,

Whilst I am not aware of the route of the oil flow, I take what seems to be the same stance as yourself. I had my PTO pulled at the first engine service in my ownership, spring 2012, 20,000 miles. The splines were reported fine, same again this last spring. On each occasion the engineer is instructed to remove, inspect, clean out the grease and repack. It only adds an hour to my account and gives me peace of mind. I think that whilst this regime does have a cost I would under the circumstances be just as fragile about the wet solution if I had one. This next spring we will be at 32000 miles so it will be interesting to see the state of the splines, I may make the effort to be there for that part.

When I researched this several years back the issue was not heavy or light duty but application. The manufacturer techs said that the dry style was not designed for continuous duty. I have never heard that there has been any upgrade of change to the part. I was also told that the PTO is adequate for continuous duty if it is regularly lubricated. Just like AGM batteries, I like to eliminate maintenance to the extent feasible.

Installing a Wet Kit to a dry spline PTO allows for continuous lubricating without actually having to do it yourself.
