good job on the change, but i'm a bit confused. what bolts did you break? all you should have done was remove drain bolt, and oil filter.
also FYI, while you may get away with reusing the crush washer this time, i would suggest you replace it every time. it's less than 1 dollar for a new one, and eventually it'll slowly leak oil if you keep reusing it.

 

The 300 does not have the same filter type that the 500 does. Their filter is behind a panel on the crankcase.

 

good to know. i skipped right over the title where he said '300'
D'OH!
:wink2:

 

Yeah all those 8mm bolts are on all the Honda stuff and they suck, better off replacing them with better bolts anyway.

I would at least get a new crush washer for next time though. After a few uses the crush washer will be pretty compressed. It’s safe insurance from overtightening accidentally.

 

I used a new crush washer; just used the old engine compartment gasket - the black one!!

No leaks so all good!!

 

just watched a vid on the 300 change. that sux! another reason to be glad of having the 500 with spin-on filter.
I never liked cartridge filters/housings especially on cars; always seems to be more of a mess (IMO)

 

The 300 is surprisingly clean it doesn’t really leak out when opened compared to other cartridge filters I’ve dealt with. Doesn’t change that a regular screw on filter would be way easier though lol

 

I think you need to make a red pen amendment to the manual!

Almost a 30% increase in torque value above that specified for 6mm screws is to my mind, incorrect.

Maybe even contact Honda.

(I'd do it but we don't get 300s in Australia).

 

I had the exact same complications. You understate the level of frustration they cause.

1. 8mm bolts crack
2. Crush washer crushes.

Then you cry.

 

I had the same problem today, I broke the oil filter cap bolts on my 2021 Rebel 300 by tightening them too much. According to the parts charts these are 6x25 NSHF bolts (with 8 mm head), which based on my service manual by default would be tightened to 12 Nm (9 lbf ft). However, looking at the actual bolts they look like 5 mm diameter rather than 6 mm (I used a ruler, since I do not have a caliper), which in that case would be tightened to 5.2 Nm (3.8 lbf ft) based on the service manual. Does anyone know the actual torque specs for these bolts? Is it 5.2, 9, or 12 Nm?

 

6.6ft-lb or approx 9NM.
