Reverso Impeller Replacement Part

[Prosideus]

I have all the supplies needed to do my first oil change on my 3116s. 14 gallons of oil, oil filters, oil sample kits, two extra five gallon buckets, strap wrench, celebration cigar.

However, my research on this site had me concerned about my reverso impeller. The boat is 2.5 hours away and I don't know the model number. So I am wondering if there is a generic impeller part number (like jabsco, etc.) that anyone has as a replacement impeller for my circa 96 Reverso unit?

Help appreciated.

" Pro " hopefully this helps... It's been a standard for a while, but if you actually need it for assurance because of travel time, # 360010. Don't forget a new gasket... Good luck, Tim

Good luck.... I'll be following your lead.

I changed mine as a pert of baselining the boat when we got it. The gasket is the tricky part it is rubber and will "extrude" out of the sealing area if there is any oil on the sealing surfaces or the screws are over tightened; it is not captured like a O-ring would be. The unit will have quite a bit of oil in it so put something under it when you remove the cover. Clean all oil from the cover and body where the gasket goes and wipe with IPA; it must be clean and dry fot the gasket tot stay in place. Do not under any circumstance use a gasket sealer.

I hope that you are a midget. I had to get a friend to change mine because I could not get down to it. If the impeller in the motor is not completely intact, you will have to find and fish out all the missing blades otherwise they will get sucked back into the pump and kill it or get pumped into your motor which would not be good. Clean the whole pump with brake parts cleaner, make sure you put a light coating of oil on the impeller when you install it. I hope that you are using Cat Special Application Engine Oil Straight 40 wt, and Cat filters. It is the only oil that should be used in the 3116.

Good Luck, Pete

Quick update. I bailed on doing the oil change. Wednesday I am moving the boat 400 miles. I will do the oil change after the trip when I have a spare impeller for the Reverso pump. Since I could not get one on hand, I couldnt risk getting halfway through and being stuck.

So, I will update with all the details when I do the deed. Thanks to everyone for providing the info. It will come in handy.

ok, help me out here... I was under the impression the oil change pump has a metal impeller in it.. ?

Bill Collector, you may be right.

As a further update I arrived at the boat only to find I have a groco oil change system and not a reverso system. So groco may indeed have a metal mpeller. Anyone else able to comment on that?

The Reverso is a rubber impeller the Groco is a gear-rotor. The impeller and cover gasket are service items for Reverso and the cover seal and shaft seal are service items for the Groco. The gears in gear-rotor pumps are not normally a wear item; I would get the Groco service kit and keep it on the boat but not mess with the pump unless it's leaking.

I found out my Groco Oil Change pump has a white plastic/man made material type impeller that has removeable veins/fins (4-sell as a set) and a hub (?) that the veins fit into. Groco sells the parts (in stock). For both I recall it was near $30.00.

Reviving an old thread. Anyone have a picture of their Groco pump? I want to order a spares kit and always thought I had a reverso OP-6 but looking at their website, my pump doesn't have a cover at all. It has a manifold, and a black pump motor that is uncovered. Thanks!
