Location of Grease fittings?

[Rollerdog]

I've read that some guys grease their skis. Can someone post a diagram of where these fitting are located?

Looked at your avatar and took a stab that it's a 2018 but earlier years are the same. http://partsfinder.onlinemicrofiche....amahapwc&a=303 Number 9 on the mid shaft bearing housing #3. It's under the black electric box. Mid shaft bearing housing bolted to the front of the mid wall. Grease fitting on left side top of the bearing housing. I unbolt the electric box to get to it or some have put an extension hose in the bearing housing. If you grease the mid shaft bearing, do it gently and once a year is fine. Easy strokes from a 14oz grease gun. Once you feel a slight resistence, stop or you can blow out the seal. Mine only take a couple pumps each year. There's posts from other members if you do a search for the extension hose. There's no other grease fittings. Some members have their way of greasing the steering cable.

I have a 2014. Thanks for the message!

I stopped and talked to the dealer and the service tech said that all bearings are sealed (so he thought)
I need a diagram to show them where these bearings are located.
Thanks in advance for any helpful info here!

The IB bearing itself is not a "sealed bearing". Yes, I've had the part in-hand - it's a very open bearing.
That said, where it is situated inside the mid-shaft housing, it is sandwiched between mid-shaft seals on either side. The grease port accesses that bearing area, thus filling the bearing with grease and lubricating the seals. In-fact, if you over-pump it, grease will ooze past the seals.

On a side-note: since that grease nipple is such a PITA to get too... several of us (DIY types) have relocated it to a remote location. Mine is mounted to the mid-wall partition, pointing aft, so all I need now, is to reach my grease-gun down in the water lock exhaust area.
FWIW, this nipple used to be remotely located in previous Yamaha models, therefore it is not hard to reach-back to the parts-fiche and acquire the OEM parts needed to relocate it.

I put a 45 degree fitting on mine and it's much easier to get to...I still have to remove the electrical box cover for access to give a a few squirts at the beginning of every season.

Sorry the last link was all the parts sections from a 2019 but still the same. In this diagram, #4 is the bearing housing and #10 is the fitting. Click on the diagram: Propulsion system - Internal from this link. http://partsfinder.onlinemicrofiche....amahapwc&a=223

Most excellent information. Thanks so much guys!

Thank you! So you do have to remove some parts to get to this?

Anyone who is interested in relocating the IB’s Zerk grease fitting, using OEM Yamaha parts . . . here’s the necessary shopping list :

1) 61L-45378-00-00 Nipple, Hose $7.29
1) 61L-5169A-00-00 Nipple, Grease $5.83
1) Hose (small reinforced/braided, fuel hose, etc...)

Directions:

Step 1 - Swap-out the IB’s Zerk fitting for a hose bib fitting.
Un-screw the existing Zerk fitting from the IB housing and set it aside – will not need it anymore.
Install 61L-45378-00-00 into the house as a replacement, as this will enable you to now clamp a hose to the IB, thus route the other hose end to a preferred location.

Step 2 – Attach the new Zerk fitting to the hose.
Once you’ve found your ideal location, attach 61L-5169A-00-00 to the end of your hose. This is the new Zerk fitting, which has the hose bib adaptor. This part also has a threaded section, if you desired mounting it somewhere.

This is how I relocated my grease fitting to a more accessible location. Details via the link above.

I remove the 4 bolts that hold the entire black electric box to the mid panel. No wiring connections are disconnected. You can then move the electric box about an inch forward and slightly to the right. It gives me just enough room to reach down with the rubber hose from my grease gun and attach the hose to the zerk fitting.The zerk will have a small black rubber cap on it that just pulls off. When I find time, I will probably make the permanent extension that is explained by TimeBandit and shown by K447, which is slightly different. But then the bearing normally only needs greased slightly once a year, so I do it during Winter lay up. I ride 50-60 hours a year and that has worked for me.

Great thread; can anyone provide a link to the specific grease, size tube and grease gun y’all are using? I assume only a small tube is required as this is a once-a-year task and I really can only think of a couple other joints, etc. where “a dab’ll do”

(My knees buckled and dropped my iPad when I saw how much Yamaha wants for “their” grease gun

This (couple gentle pumps of grease) is my #1 PRIORITY once this season is over and I have my first (of what will likely be at least 2) DIY dolly carts assembled.

Any grease gun will work, I think walmart sells a mini grease gun. So does any automotive store like Advance or Autozone, and any marine grease will work fine.
