I have this tool it's easy to use, very complete as it will break the entire engine down, comes in a cool easy to transport case. If you do any bearing replacement or ever pull the piston or sleeve this tool makes it easy. The only down side is that it is limited to certain size bearngs. But over all a great tool well worth the money.

it is a very nice tool. I think it's a must have for any serious racer. ALthough you will hear that there are cheaper bearing tools out like the ofna one this is far superior.
It can "properly" install bearings in 5 minutes total front and rear. It comes with a sleeve puller, and flywheel tool as well.
It's worth the $140

What's up BBQ it's Richmond from Cruizin. I have one and I think it's a great tool. It does bearings for GRP sized cranks and up. It has an awesome flywheel puller that works great if you have a lot of engines. I will be at the barn Friday night, so you can see it for yourself.

Not all, I don;t really know what size crank the GRP is but it fits that (GRP crank) and anything above that. I've used it on my Novarossi engines and they worked great. Not sure about the VSPEC but if they have the same diameter as the engines I spoke of then it should be fine....did I mention the fly wheel puller is awesome? The quality is excellent and it will pay itself off each and every time you use it.

I am pretty sure it works on vspec because they take the same size bearing as the GRP line. It should work on most newer .21's because most companies have gone to slightly larger bearings not smaller. I have a friend who wants to use it on a vspec in the upcoming weeks I will let you all know.

Worth every penny! I have been using mine for a few months now and absolutely love it!

It is the single best tool I have ever used in rc racing. We spend hundreds of dollars on these motors and ask them to do amazing feets (30,000 rpm + for 30 minutes). Take the time to thoroughly disassemble and clean your motors and reassembl correctly and they should last forever-aka nhra drag race teams. If the price concerns you-you could probably rent it out at the track to you fellow racers
Only caution is when using it pay attention to the exhaust port and the winged handles on the tool, I have seen a case damaged this way
Other than that well worth the money-should last forever and it fits grp, os, go, mr ninja, the only motor I saw it didn't fit was an ops/radical and I believe some of the)'s have the smaller bearing also

Do you guys still heat the case when removing/installing bearings with this tool? Or is it that good that heating the case isn't necessary? Thanks

I have seen it done both ways hot/cold-i just think the heat will make it a little easier to be sure the bearing is seated in the case completely. I heat it up to about 150 degrees or so and the bearings seem to jump in and out of the case. Get good at changing engine bearings and charge $25 to do a motor (not supplying bearings) and it will really pay for itself!!

no heat required.
