Default Anyone try out GRP's Engine Tooling System yet?

After jacking up a >$130 C6 crankcase using OFNA "cheap" $50 bearing puller I've been looking at the RB rear bearing puller and the GRP engine tooling system. The GRP is more appealing as it has a tool to pull out the sleeve, which can sometimes be really hard to do. Anyone have experience with these tools?

I finally got mine a couple of months ago, but havn't got to use it yet.

Before I gotten mine, I've had Drake use his GRP tooling kit to replace bearings in several of my engine cases. Looked really easy to do and only took a couple of minutes.

RB's system is outstanding but pricey.

You really don't need any tools though. An oven or hot plate (I use a burner on the stove) really is the best way to do it. Allows you to install the bearings without putting any stress on them.

I can tell you that the grp tool makes it so easy it's almost fun changing bearings.

I disagree, I've run into more than one stubborn bearing in my day the the tooling system is absolutely perfect for those. Also I don't normally carry an oven with me to the track

I don't either but I usually do have a blow torch. Then again, I have never changed a bearing at the track. I try to do such things at home and if I have a problem I break out a back up motor. I have built dozens of motors and have yet to find one I couldn't get a bearing out of with heat. If I ever do I just might change my mind.

I did once have need of an oven at a slot car race. Fortunately the local pizza shop obliged.

I have no problem with using a tool to remove a bearing (though so far I have found it unnecessary). I just don't like the idea of pressing them in.

This GRP set sounds interesting but I haven't seen it. Any pics?

I never needed one before trying to replace a few of the old style MR ninja bearings and now I wouldn't do it without one. It's not cheap but if your a serious racer away from home it's a handy thing to have if your at a big race...

Anyone know where I can buy one of these engine tooling kits online? Amain doesn't seem to carry them anymore and they aren't on ebay.

Has the product number changed?

The only website that seems to have them is here, but they are OOS.

The product is still referenced on Losi's Site.

Thoughts?

The GRP engine tool is a must for anyone who races and works on their own stuff. Changing engine bearings takes literally 5 mins once you have the engine apart and the tool helps pull out stubborn sleeves. This tool is a must have. I love mine. I agree it almost makes changing bearings fun . I highly recommend getting one.

I must agree this tool is fun to use you will not put off changing
out old bearings the right tool for the right job makes all the
difference and a oven mitt and a stick are not the right tools

I would beg to differ. Cold pressing bearings is more stress on the block and may produce metals scrapnel or shavings while forcing a bearing place.
