I plan on retrofitting a better oil pump on my 02 M2. I was told the oil pump from a 07 Uly. is a better redesigned pump that will bolt right up. Also that this pump has more volume. Has anyone done this conversion? | ||
| Wile_ecoyote |
Interesting idea, I'll stay posted as I may do the same. Sorry I cant answer that question too. | ||
| Buellistic |
You'll need to check PART NUMBERS !!! The latest and greatest for BUELLS is 26204-98(same as 26204-91A) which is in BUELLs to year 2007 ... The 02 M2 will already have this -98/-91A oil pump ... This oil pump will have the new BUELL BUELLschitte part number which will be the same ... A real HARLEY-DAVIDSON PARTS MAN or HARLEY-DAVIDSON BUELL Customer Service will also be able to tell you ... | ||

I wish I could find a real Harley/Buell Parts Guy! I can't find a Buell GURU that really knows the different parts over the years. I was given this info from a builder who is building a land speed bike. I was given part numbers for pump 22-26357-026 & 22-26391-06 for the gear. The part #s are from NRHS. I wanted to see if anyone else has used this conversion and really knows what changes or advantages were made in this unit.(meaning gears,casting,line dia.,ect...)Thanks for the info Buellistic, are those Buell part #s or harley? | ||

Is there really a difference in the pumps? I know they updated the gear, and that it's a good thing to replace in the older bikes, but I've never heard anything bad about the pump itself. | ||
| Oldog |
There are some differences a change was made in '01 [ says the FSM ] IIRC its supposed to scavenge better, the big thing on older tube frame bikes is to check and change the oil pump driving gear on the crank shaft if needed, they are prone to wearing out and having the teeth break and fall into the oil pump, with the resulting mayhem.. | ||
| Sloppy |
To my understanding the better scavanging pump was installed in (late?) '99. Hugh: Use the new alloy Buell oil pump drive gear -- but you can't get them at a HD only shop as it is a Buell PN. Try American Sports Bike. | ||
| Oldog |
The 02 M2 will already have this -98/-91A oil pump ... an important data point | ||
| Buellistic |
The OIL PUMP DRIVE GEAR is PN26391-06 is a HARLEY-DAVIDSON part number ... This part fits the EVO Sportster ENGINES which are in BUELL Tube Frames, BLASTs, and XB's to 2007 ... The reason for the -98/-91A is when you back off the bottom end fills up which the -98/-91A oil pump stops because it scavanges better ... The BUELL PN26204-98 was installed in 1998 models on and the HARLEY-DAVIDSON PN26204-91A was installed in Sportsters from 2000 on ... "i" would say the NEW "BUELLschitte" PART NUMBER will be the same oil pump as the -98/-91A ... | ||

So you are saying my 02 M2 has the only new and improved pump from 99 to 07. Now here's a question, I was told the Ulys. pump was a better pump? Do the Ulys. have the same part #? Sloppy I have not heard of the alum.gear (only the bronze color gear)Does it hold up? | ||
| Oldog |
The new and improved oil pump drive gear is a bronze alloy, this is supposed to aleviate the tooth in the pump issues, these gears were made standard back in '06?? I cant tell you if the XB oil pump will fit a tuber motor, I am supprised that it will, as there are other significant changes to the cam gear chest between the tube frame Buells and the XB series. American Sport Bike and or any of the sponsor dealers for badwebb can get this part for you. you will also need a number of other gaskets and small items when removing the gear case cover, I believe that its money well spent to protect the motor. | ||
| Hugie03flhr |
Thanks Oldog, I may go the easy way and just get the gear. I did however find a pump from zippers for the buell. that looks to be a very nice piece and the price reflects it. $500.00 OUCH!!!!tHANKS TO EVERYONE THAT COMMENTED! Hugie | ||
| Firemanjim |
Uly pump is the same as all the rest,get the newest upgrade #--whatever is is now. And definitely get the bronze drive gear. | ||
| Smoke |
i've put two xb pumps on my older tubers-same p/n -98. the zippers is supposed to be the shiznit. the 08xb's nosecone is different, but i don't know about the pump. tim | ||
| Buellistic |
08 XB's have a XBRR style oil pump ... | ||
| Hugie03flhr |
Buelliistic, Is the XBRR pump better than what I have (besides the gear) in my 02 M2. And will it bolt up? | ||
| Firemanjim |
XBRR will not retro,completely different design. If you are really looking to spend some cash get a Proflow,otherwise stick with the stock late model pump,it works just fine. | ||
| Buellistic |
As Jim says the XBRR oil pump is all new and will not RETRO FIT ... Proflow and Zippers are two AFTERMARKET options ... RETRO FIT H-D/BUELL parts are easily obtained at any H-D/BUELL Dealer ... | ||
| Sloppy |
FWIW, my money was returned to me by my local HD dealer on the alloy oil pump drive gear that I ordered even though it fits the Sportster line... They took the order, but I guess the factory came back and said, "you're not a Buell dealer, sorry, you can't have the part". So I had to order mine through American Sport Bike... (thanks Al!). Hugh: Do a search on KV for what you need to do to replace the drive gear. That's all you "should" do. Otherwise your stock oil pump works excellent. | ||
| Buellistic |
That is "BUELLschitte" as the oil pump drive gear carries a HARLEY-DAVIDSON Part Number, not BUELL Motor Company BUELLschitte Part Number !!! | ||
| Sloppy |
I was surprised too, but I checked on the HD website for it as a part and couldn't find it. But it's on the Buell website. Don't know why HD didn't ship it to the dealership even though it has an HD PN, but apparantly the part only comes from Buell? Don't know why, I only know that it happened to me... | ||

LaFayette, All the air-cooled Buell engines are Harley-Davidson, but the Buell specific parts (heads, pistons, headers, etc...) may only be ordered through a Buell dealership. That includes the special high performance Buell oil pump drive gear. I agree though, you'd think the H-D folks would want to have access to that too. Somewhere in this there is an interesting story. Remind Court to tell you.  | ||
| Buellistic |
Blake: Thought that was why the the "BUELLschitte" Part Numbering System was for, to isolate the BUELL Redheaded stepchildren from HARLEY-DAVIDSON ... Now, the way the Part Numbering System was set up when the Harley and Davidson family had control, the -36(first year used)on the end on the part number was for the STREET Plate Forms and -41R(first year used with "R" indicating RACING)on RACING Plate Forms, ie: WR, KR/KRTT, and XLR/XLRTT !!! Now the OIL PUMP DRIVE GEAR PN26391-06 would be for STREET Plate Forms and is TRUE HARLEY-DAVIDSON under the "CORRECT NUMBERING SYSTEM" !!! Now "26"xxx-06 tells a PARTS MAN(not a parts technician person) that this is in the OIL PUMP AREA ... TO BE A PRE-"BUELLschitte" BUELL PART NUMBER IT WOULD BE A -06Y TO BE CORRECT ... IMHO, this is just more RETRO FIT "BUELLschitte" between "THE MOTOR COMPANY" and "BMC" !!! In BUELLing LaFayette | ||

What is "BUELLschitte"??? I'm new at this. | ||
| Davefl |
What is "BUELLschitte"??? It is a nice creative way to say that it is Bull Sh1t. | ||
| Buellistic |
David: That is "CORRECT" !!! "AND" that is just what the NEW BUELL PART NUMBERING SYSTEM is("BUELLschitte") ... As you well know, you can not go to a HARLEY-DAVIDSON Dealer(not one that just has a BUELL Sign on the building) and get TUBE FRAME PARTS unless you know the H-D Part Number that fits !!!

BTW, the 07 Buells do have a different oil pump from the 06 and earlier versions. I don't have a copy of the PDF on this computer, but HD/Buell issues a listing of all the improved parts for each model year and the 07 issue shows a new oil pump for the 07 Buells. It has increased scavenging capacity (the part of the pump that sucks oil out of the engine and pumps it back to the tank or swingarm). This might be good for slightly increasing horsepower by reducing parasitic drag of oil on the crank and reducing oil consumption (less oil to get thrown up against the rings). The brochure says the pump will retrofit to all earlier Buells. The brochure even shows side-by-side photos of the new and old oil pumps and points out the differences. The scavenging section of the 07 pump is "thicker", while the pressure pump section is "thinner", so that the overall pump height remains the same. The gerotor gear in the pressure section was changed to keep the same capacity despite its thinner cross-section. I have the PDF of this brochure on my home computer (I'm out of town on business). I'm pretty sure it lists the part number for the new part. Ping me if you're interested and I'll be glad to send it to you in a little over a week. | ||

Hugh I'm interested in the part number and PDF when you get a chance. I miss Summerville and charleston in general. Thanks Joe (Message edited by bad_karma on December 14, 2007) | ||
| Hughlysses |
Joe, I wasn't able to find a copy of the PDF on my computer, but I did finally find it out on the net. Here's a link (it's an 8 MB file): http://www.konaharleydavidson.com/pdf/2007%20model%20year%20technical%20forum.pdf The old and new Buell oil pumps are shown on page 81:  It doesn't show the new part number, but if you order an oil pump for a 2007 Buell or Sportster, it'll be the right part. Hugh | ||

Gentlemen: That is right as the -91A Sportster OIL PUMP is the same thing as the -98 BUELL "TUBE FRAME" oil pump ... The XB oil pump has a different Part Number because it uses different oil line hook up fittings ... In BUELLing LaFayette |
