Aluminium Water Pump Gear

Post by **oldjapanesebikes** » Mon Aug 03, 2009 10:40 pm

Fred (Buffalo-guy on the board here) has had a small number of aluminium water pump gears made just to test out the concept. In the photos below, they are shown on the right of a new nylon water pump gear (part number 17522-31031).

Due to the small number made, the price would be in the USD$140 range - obviously if more were made, the price might be lower. Any interest out there ? If so, please PM either Fred or myself.

Thanks !

I bought one some years ago from somebody, I believe in Europe, works fine so far. seems like it was about $100 shipped.

I'll be the first to admit that the cost is most likely prohibative for most, if not all. It just seemed like a worthy experiment, and the cost only came to light when 3 prototypes were done. They do fit well and look great, and I will be putting one on the gold GT when it gets resurrected later this year. Water pump gear failure should be a thing of the past. I'll keep you posted, and if anyone is truly interested, I'm only a PM away.
BTW, Ian is way more computer savvy than me, hence, he posted the thread and pictures. In case you were wondering. Cheers.

Lanes got grammeritus, however,,, Fred your gears look quite impressive i need to take a look at one in the flesh.
You think for that money you could add anodizing into the deal???? LOLOL

Allan.
I'm not sure about anodizing, but spray paint is cheap. Maybe a "gear gazer" on the timing side cover to see it in action. Lots of options. You will see one when you're in town, I'm sure. Cheers.

All bling issues aside, would anodizing be helpful or harmful on a gear? Back in the day I used Aluminium timing gears in my Triumph twins and they had a tendency to shed some metal over time as they wore, but not usually anything serious.

Anodizing leaves a nice hard surface but I have no idea if it's suitable for gears.

At 140 bucks for a driven gear, an electric pump is starting to look really sweet.

I don't remember who made them in Germany, but Reiner carried the german aluminum gears for awhile but he's out now (I tried to buy some from him a year or two ago)

I think this aluminum gear, anodized or not would be better than the oem's plastic.

Of course it's not the tooth surface that was problematic, it was the gear body cracking up.

my concern is that suzuki made them out of nylon/plastic for a reason .
lightness maybee but i think also to take the wear on a cheap easy to replace part.
i noticed that they all crack from the small spigot end first so i made a surport sleeve to try and mitigate this.
what do you think .??

it is pressed on with a small interferance fit of 0.001 of an inch.

Mark its a good idea but you really only need the sleeve, the flanged portion isnt really necessary.

The other problem of course is that in different parts of the world, and at different times Suzuki still offers these gears (17522-31031) direct from dealers at a pretty reasonable cost. I bought two last August here in Calgary from a regular dealer, and I think the cost last time was something like $46 CDN each, or about $40 USD. I see there is a distributor in the UK selling them right now for £ 28.25 - the stock seems new as it has the bar code stock tag - that's about $42 USD.

If I remember to check, I can ask if they are back in stock here also if anyone is interested. I find it curious that they are not offered in the US.

yes you are right Fred it is the cost that's put folks of.
and what they don't realize is like I said in Allans post..
these are not easily knock out in minutes..precisions precisions precisions
every thing down to a thousands of an inch.
sorry to say Fred if I were wanting one I would go for the cheapest option $42.. I would buy 2. how long do these last if they for ever breaking up say after a couple of thousand miles then yours would be a better options as I would not like to strip an engine down every 5 minutes so speak.

Just based on the engine tear downs I've done, I would say the nylon gears are good for a minimum of 30,000 miles - in some cases much more.
