Devilman's Pump Thread

[Devilman]

Coming to you live from the south....  :wink: :grin:

That aside... as some of you may have read, I pulled the pump outta the boat to have it gone through. Main reason is that I've been running it since I bought it (2005) with no prior knowledge or maintenance history on it. Grease pukes out of it like chicks at a redneck keg party so I figure at the very least it will end up with new seals & bearing & not be so messy back there around the engine.  :cheesy:

This is not meant to be a step by step instructional thread per se, as Duane will be the one going through it. If he wants to make one out of it showing disassembly & stuff, that's fine. Duane you can chime in however. I am mainly posting to show what I did & found so far.

Started by unhooking control cables (steering, forward/reverse, & diverter) & then pullin the droop/diverter off.

Moved on to the transom cover/adaptor next, which came off surprisingly well.

After that & removing the pump bolts the greasy, dirty biatch is out on the ground... :wink:

I'll also say that using anti-sieze on the hardware made removing the pump a snap. Everything came apart smoothly & looks as good as it did when I put the pump back in it in '05. Worth mentioning is that labeling & using a Ziploc bag for storage is a good way to keep track of all your hardware. As you can see, my granddaughter likes Dora stuff, lol... :cheesy:

Once I had the pump out, I did pop the bowl off to see what I could see. To my untrained eye, it looks as good as it did when I bought it, other than some nicks in the leading edges of some of the vanes. Somebody else may notice something I may be missing.

Guess if I was gonna go with a stuffer plate, now would be the time. Anybody have any thoughts on that?

Vanes on the exit side don't look too awful bad, there is a few nicks/gouges though. Not sure if its anything to attend to or not?

This all I've seen of the impeller so far. Haven't noticed any cracks or outstanding damage(so far, lol). Guessing it's an A by this stamping...

Got some pics of the loader too since I was right there. I'll post those soon & see if its a bad mofo or just a POS, lol. :grin:

i wander if Duane will check the clearance on the impy and ring before he removes the impy....  do you have a shouldered ring :smile21:

I dunno, probably? If all it needs is bearings & seals, thats perfectly fine with me. I wasn't planning on changing impellers unless something was wrong with mine. No idea what kind of wear ring is in it. Takin it over there after work though.

 

[KONA77]

overall your pump looks better than mine when i tore it apart,  mine looked like someone used it as a wood chipper,  the impy was all chewed up and had some vain damage  :smile18:

 

[Devilman]

I'm hoping its in decent shape & that my worry will be for nothing. Like I said at the very least it will have new thrust bearing, seals, & I'll know the clearances are good.

$$$ saved will pay for the trailer tires I had to buy the other day when we went to Medina. :tongue: :grin:

Sounds like a Patch story now! :smile26:

like i said looks good,  Duane will know more,  when he inspects it,  looks like just a simple refresher... to me but i'm just looking at pics  :smile30:

Pman gonna try a jack another thread  :smile21:  :smile27:

 

[Patchman]

Looks like it had some sewage sitting in the bottom of the bowl! I am an untrained eye though! :smile30:

Jack, who's that? :huh:

Yep.. When we left that morning, something didn't feel right pulling down the road, but wasn't sure what it was. About 10 miles outside town, left side tire seperated...  :tongue: Had road hazard on 'em though, so threw on the spare, went back to town & got them both replaced.  :wink:

LOL, Medina is the last place I ran it. And here I was talking about how nice the water was.. :smile26: :grin:

Looks good! I noticed the stake/punch marks around the bowl seal....I did this to mine and the damn seal popped out after a year of running.....pulled the bowl, and found it was chocked full of grease from the previous owner (shoulda checked it I know) anyway I flushed the oil cavity, installed a new seal and this time used some permatex right stuff on the outer edge of the seal to make sure it stayed home (recommended by Tom at JBP) so far so good! YMMV.

does a stuffer cover the rear end of the pump like after the baggie pic?

YEP....

wow I got more pump than I figured when I bought it. so whats it do? increase the pressure or what?

Stuffer plate blocks off that void there in the center. From what I've read about 'em the general idea is that by blocking that off, the water is less turbulent, makes a smoother transition into the vanes of the bowl thereby making the pump more efficient.


Or some shit like that. :tongue: I'm sure somebody around here has a better grasp on it than I. Hopefully they will shed some light on the sublect.

 

[hellnback]

sweet.... Somebody spent some money on my pump at one time or another... what with the loader,inducer and stuffer maybe my BBO isn't enough for it.... :smile29:

This stuffer not only fills the bowl cavity, it also stuffs the void in back of the impeller, reducing pump "cavitation and slip".Improves holeshot and Mid range power!

Ok, pulled the bowl off, and the first thing I see is a wear pattern on the shaft I don't like. Notice the normal wear on this side of shaft in the bushing area:

Now turn the shaft 180* and check the wear pattern:

Anyway, on with the teardown. Remove the nut....

Good idea to soak the threads with a penetrant..install the puller, and remove impeller.

This impeller has a lot of wear ring wear, as well as some pretty serious cavitation burns that are deep.

remove the bearing retainer...

remove the packing gland retainers...

remove imp key from shaft, and slide/encourage the shaft out the front..

heat the wear ring until the plastic liner melts out...

And pop the wear ring out with a screwdriver.

And, ummmm..... no need for digital calipers here......
wow, this thing was LOOSE........

Kenny if you need an impellar, I have one for you!
