GRP Engine Tool
 

Anyone have any experience with the GRP engine tool for tearing down an engine good or bad. I know the good old heat method works, but when there are special tools that do the job, why not use them? I am about to use this tool to break down an engine and replace the bearings. Any comments or special tips?

I'd like to find out if GRP's engine tool will only work with GRP bearing sizes? It would be nice if that $170 could be used on other engine bearing sizes.

i have used my GRP engine tool to tear down vspecs, nova's, grps, and mugen motors. Works like charm.

Are you heating the engine case at all before using the tool?

You dont need to. But i do, just to make sure.

I suppose you can heat it, would not hurt at all. But, you don't have to and it will smoothly pull them and put them in!

It's a very nice tool.

+1 they are great. The only size you can't use them on is 13mm bearings. The tool won't physically fit into engines that use 13mm cranks. I have used mine on OS, nova and GRP engines with great success. I never heated the block up at all either. It pulls them and installs them cold very easily.:nod:
