Hi. I've just started to remove the cam followers "tappets" from a spare casing that I happen to have. The actual followers are absolutely solid in their housing. One of the housings is also abso solid in the casing.
Are they a simple straight through stem the same as a valve in its guide, or am I going to find something complicated in there.
I dont want to damage a spline for instance.

Now have the answer.

Hi.
I am still having serious trouble removing the tappet housing from the casing on Sloper. I have tried all the normal things that I know including putting it in the oven at 200 degrees etc, and so far my success has included breaking open the jaws of a spanner The next action will need to be something drastic like welding a bar on to it. However before I go down that line can someone confirm that they are both the same thread and not that one is LH. Fortunately its a spare casing.
Then I really would feel a bit silly.

Can you post a picture so we can see what we're looking at? Something is wrong there. It shouldn't take brute force to get it out.

Thats my thoughts. so I'll put a pic on later if I can still remember how.

Hi ;) ;) ;)
Herwith some pics of the offending item. The Cam follower is completely free in the housing. But I cant shift the housing in the casing

Hi Mike
Couple of ideas may not help a lot but worth looking firstly there's a stud that goes alongside the housing that as a curved section cut out of it this fits about halfway down the housing (just a lose sliding fit )it sticks out the crank case and then goes through the timing chest cover and then as a nut that helps tighten the cover on . If somebody has tried to tighten in the past and snapped it off against the cam follower housing it may be the reason you can't undo it .
On one of my cases someone had tightened the housing in and ripped the Thread and I struggled to get it out, it was just nigh on impossible ,as you say welding a bar to it to give you extra turning ability may work but will probably damaged cases .
When mine did come out I ended up only having half off my theads left that we usable

There isn't a hidden screw anywhere is there? Similar to the fitting on the cam followers on the A10
I don't think so. I never took mine off, but the parts book mentions a plate, but you took one off , correct? the threads should be the same. Have you tried putting a good fittng spanner on it and instead of just forcing it, give it a few good taps with a hammer. See if it moves even a bit. if so you're on the right track.
Hi Mike, I know you're familiar with the M20 and I recently broke a spanner taking the same part off on an M20. It's the only time this has happened on approximately 12 M20/M21/B31 engines I've rebuilt. I just used more heat from a propane burner and eventually it shifted. All the best, Glenn
Hi,
I had a pressure relief valve on an A65 case that would not move and was so chewed up nothing would grip. I had read that striking an arc with an electric welder can break the bond of corrosion. So, I thought that I would give it a try and just as a bit of insurance I would weld a spanner to it.
I struck the arc and blobbed a bit weld on but before I could put any force on the spanner the prv came undone as if it had never been tight.
Dave.
