Hi all,

I've stripped all the steel from my crankcases to get them vapour blasted. Except for the inlet tappet guide, which refuses to shift despite lots of heat and my longest spanner.

My question is, is there such a thing as a socket or ring spanner that'll fit the square guide, to help get a bit more leverage?

If I remember correctly, I just masked the area with a piece of wood and a stud through it.

Hi Ron,

Thanks for the link; that's just the tool I need. Is it a BSA special? I've tried 12-point sockets, but nowt seems to fit well.

Success! Heat (again), great big Diamond Calk Horseshoe Company of Minnesota adjustable spanner and a Hilka lump hammer. I won't be uploading the video, mind.

Thanks for being there all of you.

That tool is homemade and I've seen a similar one or the same one by one of our Dutch forum members. The answer is, put it in the oven at 200 degrees till the case is sizzling hot. When your wife comes home, blame the neighbours for their smelly bonfire. Ron

There is no tool on the market for this job that I know of...I made one using an old 1/2" drive socket and a bit of hexagon bar....I cut off the 'socket' to just leave the shank with the square hole...I then filed that to be a good fit on the square head of the follower guide...
Next I drilled the hex bar to the correct diameter to take the socket shank with a 5/16" hole all the way through for the tappet shaft to pass through...Then I welded the prepared socket in place...A bit crude but it works a treat...I made it years ago after I got fed up with stretching spanners and damaging the tappet guides...Heat the cases before unscrewing the guide...Ian

Yes, it is my video... just like Ian I was also struggling with open-end spanners :upside_down_face: and I made the tool straight after Trevor shared his clever idea here, Thanks again Trevor :+1: :+1:
