Centrifugal service questions Honda XR150L
« on: August 14, 2018, 09:46:54 AM »
Hi all
I need to do this service in 1000km. Now my question. For this I need to remove the right hand cover. As I understand, it has a paper type gasket.
Is it just clean and fit or must I smear something like liquid gasket sealer on it.
I don't fit bolts and nuts on a frequent basis and I am afraid of over tightening or uneven tightening. What is the recommended torque specs of the cover when putting it back. I would think 15Nm?

check out this vid on youtube...ok..its for the 125...but it also has this "centrifugal" oil filter

15nm might be a bit much. 12 nm at most i presume?
If i find any more relevant info i will post here.

Regarding your questions.
Dont be scared to start making your own paper filters. With a bit of practice you'll end up with a nice one.
If you are concerned with loosing bolts and nuts....use a bit of Locktite on the threads. Yeah...after a long time its a b***ch to remove a bolt stuck with Locktite, but a little heat does the trick.

MANY thanks!

Well, in 1995/1996 my father and I reconditioned a 1989 Yamaha XT350 and for this exercise we made our own paper filters where needed. Smeared very little liquid gasket sealer on each side when installing. It did sweat after many km, but with my Honda it will probably start sweating when it is time to service the filter again.

I have watched that video on youtube. Will be an easy job. Was just concerned about how tight the bolts as I don't want to over tighten or uneven causing warpage or maybe cracking of the aluminum side cover due to uneven tightening.

I generally follow this chart if i dont have torque values for a bolt.
yours should be 8mm bolts...12ft/p...around 16nm
There is many calculators on google...

on this chart you see 8mm can be from 10nm to 27nm
Honda might have used a better/higher carbon alloy but in today's market i wont take any chances.
In general 8mm bolts on motorcycle casings from 8nm (on scooters with 8th generation scrap alloy) to 21nm on a bmw bike. I would default to around 14nm and use lock tite on your bike.

it also depends on how much meat at the point where the bolt goes into.
I also checked out the manual in the link i posted earlier...seems yours are 6mm bolts...then its 12nm as per the manual.
