77 oil pump

Does anyone know where to get the gerotor set,return(thick) #26491-75. My sons bike has a cracked outer gear and we can't find it in any parts books.I have a 54 thru 78 parts catalog and it says N/A. He had a bad leak and was going to re-seal the pump, it did not affect pumping oil. Can we just weld it up an reinstall?

Re: 77 oil pump

Ask a H-D dealer to run a parts search for the part you need. They may be able to locate one for you.

Re: 77 oil pump

Tried that route, they said never been available. Best to buy a new pump:) We'll weld her up an see how it works, That way we can look for a used pump while still riding it. Didn't bother asking for a price at the dealer,seeing as the aftermarket ones cost as much as I like to give for a complete machine:)

Re: 77 oil pump

Thanks Chris, I looked on-line and didn't see what I need. I have sent them an e-mail to see if I am missing it.So far the only advantage to this pump is the ability to remove from engine while in the frame, by not making the parts available Harley makes sure you spend money on a new one. This is exactly why my last new machine was purchased in 1975.

Re: 77 oil pump

Don't you love how dealers avoid doing any work to make money (if it's not on the shelf, they don't care), and then complain how poor business is?
Parts "never available", in general, do not have part numbers shown, but are available only as part of a sub assembly.

Re: 77 oil pump

Thats how I look at it, Panic. Why list it with a part number and then put N/A next to it? They used this pump until 85, you would think there would be parts available:)

Re: 77 oil pump

The MoCo has done business like this for years. All manufactures do it. Just take a look in your parts books from any year of model. Example....wla mirror, sold as an assembly or a separate extension stem. Parts books do not show a part number for the clamp or first stem section of the mirror but those parts were available to some sectors of the consumers. The fasteners for them were also.

Re: 77 oil pump

To be fair it's not just H-D who pull this sort of trick; it's rife across manufacturing industry, and as items get more complex so it becomes more difficult to obtain specific parts rather than modules.

Googling H-D part numbers; been doing it for years, very useful when finding OEM mufflers for my 72.

Re: 77 oil pump

Tig welded the crack an dressed it out, its reinstalled on bike two more new oil lines an we'll see how it works. We'll put the new gerotor on the shelf when it comes in an install at next rebuild or problem, whichever comes first:)

The MOST IMPORTANT TOOL you need when working on an old Harley is the parts book FROM THE YEAR OF YOUR MACHINE. Not a parts book that covers the year of your machine in a spread of years. If you have a 1967 you need the '67 parts book. If you have the book that covers 1959-1969 you will see the part numbers being sold in 1969 that may have replaced the original part.

Re: 77 oil pump

The parts book I have covers 54 to 78, first year of this pump is 77, and sons machine is a 77. The part number is 26491-75? Why 75 if not used till 77? I would love to have an individual parts book for each of my 9 machines, I thought they only printed the parts books to coincide with the manuals. Sorry 10 machines, I allways forget the pre-unit:)

Re: 77 oil pump

Many parts books are available in reprint. Originals are more expensive and can be found on eBay. Many years don't have a parts book but instead have a supplement to the previous parts book.

Gerotor 1/2 sump engine was ready to go out in 75, most parts for it end in -75, but whatever happened in the factory delayed production till 77...

Re: 77 oil pump

Don't know if it's true but 2 different old time dealer mechanics told me that before making any oiling change Harley would release small batches of the new parts in to certain markets for a couple of years and watch for problems.
