Jack Shaft Bearing Replacement

[KZOOVIPER]

2005 Vector

I am thinking I need to replace the Jack Shaft Bearing (Behind the Secondary) and I am looking for instructions for the easy way. I have never changed one with a tapered collar like this.

Thanks

There's TONS of info, including fantastic picture tutorial on the site here... so a quick search, and I'm sure you'll find lots.. if for some reason u can't find anything... post back, and I'll post a few links for u....

EDITL Changed my mind... <g> Here's one... it's not specific only to the clutch side, but all bearings... The one your looking for is in there...

Rite at the very top of every screen you will see "TY TECH" It's in there...
Don't feel stupid lol... The TY TECH section is NOT included in the 'search' as it is not technically part of the forums.... A lot of people I find miss rite past that link at the top of the page.... Dig thru it all bud... there is hours and hours of reading to be done in there.. have fun... and your very welcome... glad i was able to help...

Looking for some advice guys! I was just out getting my Vector ready for a ride tomorrow, and I noticed play in the jack shaft( clutch can move up/down, feels rubber mounted if that makes sense) is my bearing gone? I took the clutch off and shined a light around the shaft and I can see light behind the shaft, looks like the collar on the shaft is either missing or moved on the shaft. Should the locking collar be tight to the bearing, it is about 1/4" from the bearing right now. The Vector is my back up sled, it would really suck if I couldn't ride tomorrow! Thanks guys.

Thanks again for the info.

FYI- you might find it hard to change just the clutch side bearing because it is hard to get off without removing the jackshaft (and chaincase). There are some posts on here about different ways but the easiest seems to be applying heat around the bearing so that it can be tapped out from behind.

Are you saying that I can remove the bearing without removing the Jackshaft? Do you apply heat to the bearing or to the Jackshaft?

Some guys have done it by heating the housing area around the bearing so that it expands enough to allow the bearing to slide easier. Others have tack welded a slide puller to the bearing to draw it out.

if the shaft is ok
the bearing can be pulled out without removing the shaft
it is easy to spin the shaft if the collar has moved
i had to remove the chaincase as the shaft was spun
it lost 7 or 8 thousandth, but that was enough as the collar has to fit the shaft and the bearing perfectly.
it is a special bearing also as the inner race is tapered
to fit the collar
also make sure you get a new collar and locknut
i hope it goes well for you

Do you have a suggestion on how to pull the bearing out, without using the shaft as a puller ?

Thanks for the replies.

I haven't tried it but have heard others say to heat the housing around the bearing so that it expands and you can tap it out from behind.

there is a great link on here that shows pictures and everything
i don't have the link handy
and it will take me time with my dial up internet
darn slow speed
the puller is a hammer puller type with a 1 jaw gripping the inner race
the collar has to be tapped out first

The bearing is the easy part. The hard part is removing the collar from the bearing.
Another note for everyone with a Mono skid, you can use the same spanner that you use for adjusting the transfer rod on the nut on the collar of the jackshaft bearing.

I am having a real tough time with this! I had the chain case all apart, removed the jackshaft and replaced the tapered collar and lock nut, put things back together and had the chain case all buttoned up and found a spacer/collar in my drain pan. I cannot think for the life of me where it goes? Everything went together good, fits tight, I am stumped!!!!!!!!!

It is a little bigger than the collar that goes on before the brake rotor if that can help anyone identify it.
