Replacing fork seals
« on: 21 April, 2020, 01:24:02 AM »
I read a posting from Robo dating back to 2015 (changing the fork oil) . The pictures are no longer available and it looks like every experienced member replied with kudos. One of my forks is leaking and there is not a mechanic who will open their shop at this time.
Any chance that posting could be refreshed? Any advice as to how to change the seal would be welcomed. :034:

Hi There,
Done this job on both my front forks last weekend (CBF-F)
First thing to do is slacken the damping on forks fully down ie. turn adjuster anti-clockwise all the way.
Then do following:
1. Loosen caps on top of Forks.
2. Loosen top yoke clamp bolts.
3. Remove brake calippers.
4. Remove wheel.
5. Remove mud-guard.
6. Loosen bottom yoke clamp bolts.
7. Jiggle and slide both forks down & out.
8. Loosen Hex bolt inside bottom of forks.
9. Remove top cap with fork uprigh.
10. Remove spacer, washer & spring.
11. Pour oil out while pumping the fork.
12. Prise out dust cap & retaining clip underneath.
13. Remove Hex bolt inside bottom of for & slide out damper.
14. Pull bottom & top of fork sharply away from each other several times to free oil seal.
15. Remove sea, washer & copper bushing. Keep all parts in proper order. Clean all parts.
16. Replace damper thread in bottom of fork tube and slide tube into fork leg. Hand tighten Hex bolt back into bottom of fork leg.
FOR THE REMAINDER GO TO THIS LINK on YouTube.

He gives very good instruction.

Take care

Love him or hate him Del Boy gets the job done with good commentary.

Your motorcycle descriptor is confusing. If I was a gambling man I'd wager your CBF1000A(2012) is in fact a 2012 registered CBF1000 A-A SC58 (MKI). If that's the case change it to CBF 1000 A-A and ignore Stvlas's instruction to "slacken the damping on the forks fully down", you and he have different models. If that's not the case I apologise.

Also read the Honda workshop manual, its all in Section 14 (front wheel, suspension and steering) pages 19 to 30. Its an easy 5 minute read with a step by step pictorial guide specific to the job in hand.

You'll need 1L of fork oil to achieve the 129mm air gap. I filled mine with 15W Valvoline Synpower front fork oil, off the shelf at Halfords, to stiffen the forks the little. The Honda specification is for 10W fork oil.

Thank you both. Since I am in Canada and this type of bike sold poorly in North America, resources are very limited and the nomenclature is obviouly different. I have no idea how to match the nomenclature to identify if it is SC58 or a CBFF. Is there a way? I thought those with one can (my model) were MK-1's, no?
I will read and watch avidly. looks like a whole day job. Thankfuly I still come to work every day so it will wait till the weekend.
Much appreciated.
M.

Apologises then, that's why I'm not a gambling man.

The MKII as it is known here has a four into one exhaust with a single silencer and digital clocks. If that's what you have there are several models which are CBF 1000F, CBF1000FA, CBF1000FT and CBF1000FS. Which is which I don't know but there will probably be some clue in the registration paperwork or VIN number. For what its worth Honda call it a SC64.

OK, thanks. I guess I have an MKII (4 in 1 exhaust and digital displays). As to what subtype, beats me. It has half fairing and ABS if that defines it. No need to apologise. :027:

Click on profile and forum profile and change your bike to "CBF 1000FAC" then we'll all know roughly what you have

F=SC64 (that's a MKII)
A=ABS
C=2012

The forks, seals and oil, should take 2 hours, home mechanic 3 hours, first timer home mechanic 4 hours

Happy days ahead
