M8 cam tools

M8 cam tools

g'day peeps, going for a long shot here - but do any of you guys/gals have an M8 cam bearing removal/install tool you'd be interested in selling or even renting out?
Early in the new year I plan on replacing the stock cam for the SE8-447 tq cam, and upgrading to the latest oil pump kit while in there.
I can't justify (to SWMBO anyway) spending ~$300 for one time use tools.
Mixed views out there regarding the bearing needing replacing, whats the opinion from those with more experience - do I need to do it for this cam?
I plan on doing the work myself.

TIA

Hi Doc,,,
The consensus is with any cam change you should change the cam bearings.. Of course if you only had a couple of thousand km, it might be ok to keep the original ….

The consensus also , while your in there , (again depending on km), replace the lifters ,,, tensioner ,,, etc ….

Cant help with the M8 cam bearing tool …… But if you live near a good workshop ,, trailer the bike there and get them to replace the cam bearings.. Especially if you bought parts from them … Just an idea …..

Doc the puller is the same as the twin cam, only difference in the install kit is the plate but you can knock the new bearing in using the bearing support die and the rod, know anyone with the twin cam stuff?

I bought a Twin cam bearing tool kit from this mob.. Has done the job on a few bikes ... (they were then called a Heartland tool) …. Add approx $30 for postage … Better than $300 for something like the Jims tool ..

Worst part is getting the old ones out.
I just machined up an installation tool from bar stock, went in easy after being cooked to -18 overnight in the deep freezer.
Can send it to you if you want to cover postage Doc, but you will need a puller to get the old ones out.

This is about the cheapest bearing Puller tool only for the M8 on the net ,,,,
So Doc,, Looks like you have all options on the table now !!! Must say , it is a bit strange no one has the puller and installer tool for the M8 in their garage !!!!!

thanks GM, Mark and Ken for info and offers.
Mark I did actually look at the MBS gear but it'd still be close to $300 AUD by the time it's here. I did find a cheap twin cam puller for around $80 delivered on fleabay (haven't purchased yet) and was considering purchasing from FuelMoto, the Georges Garage installer (~$200AUD delivered), so still close to the $300AUD mark anyway.
When I did my evo I loaned the bearing remover and used the old cam to install the new bearing, and may end up doing as both GreaseMonkey and Ken have suggested, place the new bearing in the freezer o/night and tapping in.
Ken, thanks heaps for the offer of the loan of your installer spigot mate - for now I'll keep my ears open and ask around to get one a bit closer to home if possible, no rush as I'm still ordering parts.
Don't really have access to a trailer to take the bike to a workshop to just have the bearing done.
Wasn't really sure if anyone would have done this themselves yet and had purchased tools that were now lying around that they may have wanted to sell/rent, but figured I'd give it a crack.
thanks again guys

No worries Doc.
You can buy a cheap set of those finger type bearing pullers for about $60 on flebay, is where I got mine, and have used a few of the sizes now, latest was to do the steering head bearing races, and I did my wheel bearings with one a few months ago, so have paid for themselves for sure.

If you have access to a lathe, I can send you the tool dimensions, it is on one of my earlier posts.

Cheers
Ken

cheers mate, I can vaguely remember your posts on that, I'll do a search. You wouldn't believe it but only 2 months ago, our awesome neighbours of 16yrs moved into something smaller/newer and old Jimmy was a great machinist and had a lathe in his garage - made quite a few little bits and bobs for the old fatboy over the years for me, still have his number and may flick him a line.

If it's not urgent, I may be able to make one for you when I go back to work soon, new boat so not sure if it has a lathe.
Your old neighbor might come good for you.

Moik, I'll post up when I do get it done. Probably won't add more than what's already been discussed on other forums though.
main reasons I'm doing it, is because I like to tinker like most of us?? bit more exhaust volume without being obnoxious, better overtaking torque and good excuse to fit the new 8 lobe oil pump at the same time. Staying with the SE cam as I have the SE pro tuner and there are maps for it. Probably won't ever get the bike dyno'd unless it runs like shit tbh.
