I want to know as I'm dismantiling some ones I have spare to compare the bores on the two, as I've heared they vary. James I've no idea mate. Heat up with blow torch? MM is your man SillyBilly LOL! Where the hell is he? Or is it to early for him? James Probably gaffa taping his car together before it collapses into a pile of rust Mamodman123 James you bad mouth the car and I run you over...simple the caps are just a push tight fit, a little heat may help not too much or the cylinder will fall off the block If you can avoid taking them off then do so.

I want to know as I'm dismantiling some ones I have spare to compare the bores on the two, as I've heared they vary. SB - the cylinders on a Mamod are now of one piece of brass. Earlier ones were two peices, ie a brass tube and a backing/port face plate soldered to it. Only the very earliest cyclinders had end caps, such as the SE4. A Mamod cylinder is a simple peice of kit. Beware when rplacing them as cylinder and engine frame port faces varied in spacing and number (ie if the engine was reversing type or not). Bore were generally the same, although the newer, say 1990 type on will not fit earlier 1950/60/70 type. Strokes generally varied depending on model - ie an SE3 has a much longer stroke than a TE1 or SR1. Pistons varied too from the earliest 'power piston' type with thread/twine sealing 'ring' to the plain type and the 'new' power piston with a groove milledinto the piston. Let us know how you get on! Mike Chris Think he might be talking loco ones Mike, which are a different kettle of fish. Interesting to know they are push fit though, I just assumed they screwed in.

CCairns Dismantling a cylinder Hi William, Some time back I got some loco spares on ebay which included a near complete O ring cylinder upgrade kit. Looking at IP Engineering's Refurb Kit page ( http://www.ipengineering.co.uk/page74.html), you can just read some of the instructions. Use a small screwdriver through the collar and twist and pull to remove it from the piston rod (worked well on one example I tried but failed on another - do not have a vice set up for pulling power yet). Use a Mallet (or soft hammer) and tap piston against front cover till it pops out. Then using a suitable flat punch tap the piston against the back cover till this pops out as well. You now have a dismantled cylinder. Here is one I produced earlier: - And a comparision with the O ring upgrade: - Does anyone know if these green o rings are special high heat ones or can any O ring be used. One of the O rings with these bits was perished so I only have one O ring for 2 cylinders at present. Chris Cairns. SillyBilly Thanks for that Chris, it'll come in handy when I buy a refurb set.        The Unofficial Mamod and Other Steam Forum Forum Index -> Locomotives Page 1 of 1
