Bagstrs Trivial Mechanical and Equipment Issues

Recommended Posts

Moto Ownership is about Riding and Maintenance. The Ride Reports take care of that side. I had a thought to compile a number of these little maintenance issues here in one thread.

We will see how valuable this concept is.

Front Axle Grease Seals

Six months or more past, I replaced the grease seals on the front axle of my 2016 KTM. Un-knowingly they were installed incorrectly. The seals have a sharp outer lip and the steel spacer has a narrow groove ring. When installing the grease seal ( by tapping in with a socket ), the seal can be pushed too far toward the center of the hub. This can cause said lip to be out of alignment with the spacer groove. In my case this misalignment created a high friction point and premature wearing of the grease seal.

I believe my spacers are OEM, and when installed the narrow seal groove is 1 or 2 mm outside of flush with the hub. Leave the grease seal that same distance and you won't have pre-mature seal failure.

     HHmmmm,  moderately a concern to know.  Personally, I would ( and did Not ) prefer to live in ignorant bliss until The End on a desert wash, miles from rescue.

Oh, Wait, I had immediate rescue.  "Who Me, Worry?"

I ordered the parts today and some tools- cha-ching!

But as long as I use fresh fuel and stay out of 6th gear in a sand wash, the worst case is just riding very slowly back to the truck. It will wear out rather than catastrophically fail.

A couple weeks it will be as good as new.

So was it rings or valves other than the picture not details so what are we talking about here?

Mine's rings. 
 

I’ll replace piston, cylinder- r&I valves, replace only if necessary, clean head and valves, new valve seals and misc gaskets etc. 

I’m also replacing coolant hoses, including the frame T  

 

partsbill so far (with discounts) is about $1k

If you can get the silicon replacement hoses, I used those on bikes with over 100K miles they are the bomb

Yup. Already waiting for me.

So honest question. Why replace the radiator hoses or remove the thermostat? It's not like they are a high failure item. Bling?

Hoses just fail over time 

thermostat is more a bike specific thing imho

In my experience if they're well cared for (i.e - regular coolant replacement, etc) they last a very long time but I'm pretty anal about inspecting things during routine maintenance so would never reuse a hose that looks suspect. Actually never seen one fail other than impact related.

On bikes like the ktms what happened to me was a breakdown of the hose internally and it started to weep along the cords to the ends Under the top rubber layer.

dunno why but the silicon replacement never failed like that in my experience

Interesting. Out of 10 water cooled bikes I’ve owned haven’t seen that but it’s certainly something to look out for.
