  1. Decompression gear

    In LW spares book 518.5 published in 1955, it shows the dual anvil rockers and the cam that moves the rocker to a second position to increase the tappet clearance, thus giving max compression as the valve would close earlier than normal, this would coincide with the lever being in the No 2 position. It was probably fitted to engines supplied with hand start only. As Martyn comments it was more common on L2'S. Its also worth remembering that the manuals are pretty much backwards compatible in that the information they contain applies with small variations back to 1931 Steve
  2. Gardner Engine Forum

    Gardner Engine Forum was formed in 2001 by a group of enthusiasts all of whom were or still are narrowboat owners. In its infancy it was supported by Gardner themselves and later Gardner Parts Most of our members have narrowboats which by nature have the smaller engines fitted i.e 2-4Lw's and 2-4 L2's The forum grew out of some Rallys organized by one of the founder members and has been holding rallies every two years since, normally in the Midland and Manchester Area. We don't have many members in the South of the country. On the website under publications can be found PDF copies of all the newsletters published. We publish 2 newsletters per year so getting an answer to a query would take a long time. If you want quick answers then this forum or the Gardner Diesel engine face book page (nothing to do with the forum) is the best place to ask. We will be holding a rally this year to celebrate 150 years since the formation of L Gardner and Sons. It will take place on the 15th and 16th of September at Etruria. If you can make it you would be most welcome, you don't have to be a member to attend, we are a friendly bunch who are happy to pass on our collective knowledge Enjoy your engine, they are fine pieces of engineering. Andrew no doubt had sourced an L2 manual and left it with boat, if not pm me. As Athy commented , Graham Edges book is about as comprehensive a history of L Gardner and Sons, there is also "Gardner A product History over 125 Years by James J Francis", copies available from the Anson Engine Museum. A much smaller book as as the title says it is about the different types of engine. Steve (GEF Vice Chair and general goffer)
  3. 4LW starter battery size

    Depends on which manual you look at. My quote is from No 67, (which I believe is the last version published) it does mention that it my need to refining depending on the amount of electrics on the vehicle. Not normally an issue for a dedicated start battery on a boat. It does only give one size Steve
  4. Control cable linkages

    Probably one on this page https://www.asap-supplies.com/steering-and-controls/control-cables-and-fittings/control-cable-fittings
  5. I spoke to Malcolm Braine last night, he remembers a company called either Dami or Dani located in Stockport producing some boats in the early 1960's, maybe ties up with the previous post. He also mentioned some boats built by a company called Halmo, also known as Halesowen Motor Company by anyone living in the West Midlands , one of the owners /directors was involved with the Avon restoration, although this was probably nearer the mid 60's Steve
  6. Goliath

    Hi Glenn Yes I know Micheal. He kept the boat at Stourbridge, and is a member of the Staffs & Worcs canal society, both of which I am associated with. Interestingly my brother had tried to purchase Golitah but Michael had beaten him to it. Had I checked the EXIF info for the photo and not relied on memory I would have got the time correct. It was taken on 21 September last year at 9.42am Steve
  7. Goliath

    Ive always believed Goliath to be a Bantock. I knew its previous owner who had purchased it from David Bough or as commonly known Boffy. Photo taken earlier this year at Trentham Steve
  8. A BCN Dredger

    Yes, The Merry Hill shopping center is built partially on what was called the new level mill of Round Oak Steel Works. The photograph is taken from just through Greens Bridge heading for Park Head, next to where The Brewers Wharf hostelry is now The water intake for the water used in the mills is on the right of the photographer. The cleaned water was returned through a filtration system on the left through the bridge in the picture. In the late 50,s through to the late 70's the canal had a permanent film of oil. Delph top lock had a permanent coating of sticky oil. What is now often refereed to as the Marina at Merry Hill was originally a wider section where the filtration plant was located. When Merry hill was constructed the canal was realigned. During the redevelopment the bank retaining the canal was undermined which lead to the canal being closed as it was no longer safe. There was some speculation that the developer was trying to get the canal closed. The Pensnett railway company was integrated into the internal railway within the steel works and was still in used until the 1980's, I remember seeing steam locomotives on there, they ran until the early 1960's. How long the livery would have remained on the trucks is anyone's guess. Steve
  9. Clip of Gardners

    Starts at around 52 min. Interestingly the 1L2 is an anticlockwise version. When Trinity house decommissioned the lightships many of the 2/3 cyl engines found their way into narrow boats. Steve
  10. Prop size

    I have a 50ft narrow boat with a 3LW PRM 2:1 and 23" X 23" prop. The B.A.R of the prop is around the 60% mark, this is more commonly known as a compensated prop. A standard being 45-50% Max revs are limited to about 1100rpm, normal running speed is 475/500rpm on narrow canals 6-700rpm on Northern waterways. 7-750rpm on tidal rivers. anything more is purely just moving water for no great gain. Slow running i.e passing moored boats is at 350-375rpm. I originally had a 24" X 18" 50% B.A.R blade fitted, normal running was 600rpm and stopping was poor. All LW's can have there tick over reduced to 330rpm by fitting a different rack spring. This was detailed in a service bulletin A.I 160 issued in February 1952 Gardner's recommended prop dia for a 3LW with 2:1 gearbox is 27" Steve
  11. 2LW serial number?

    The post that you mention most likely refers to a different number. Each crankcase was pressure tested before being used, the date of the pressure test was stamped on the crankcase usually on the rear face as per the picture , this one is dated 1/11/51 and was tested as a completed engine in May 1952. On painted cast iron engines the serial number tends to get obscured by the paint job so unless you go looking it is not always easy to spot, and if it was a South African engine it may have even been altered.

  12. 2LW serial number?

    The numbers cast in the side of the block are pattern numbers and should be on all LW blocks with slight variations in numbers between 2 and 3cly blocks and possibly of different ages when there has been a modification to the pattern, and or batches of castings for identification later. The engine number should be stamped into the top of the crankcase just behind the injection pump next to the front cyl block holding down stud, if the engine has many layers of paint it is probably obscured, the injector pump should also have a number either on a plate or stamped on which matches the engine number, assuming its the original pump to the engine. The number stenciled on is probably a plant number as you suspect, I have seen ex Trinity House engine's painted green so maybe one from there. If you can find out the engine number then it should be possible to find more information by asking the Anson Engine Museum to check the records (small fee) or maybe Martyn can help. Steve
  13. Waterworld TV series 1998

    At least one made it back out as I am still here to testify. Sadly most of the contributors are no longer around to share their memories and wisdom. We owe a great deal to them and other enthusiasts of that time without which there would be considerably less of the current network available for cruising. Steve
  14. BCN

    When I came past in April this year the demolition crew was busy removing the buildings, so probably nothing left of the offices now. Used to feel like a little oasis in the middle of the industrial conurbation, another sad loss. Steve
  15. Alternator rpm

    I have a Lucas publication from about 1990 that list the ACR range from 15ACR - 28A up to 25ACR - 65A. Never came across anything above the 22ACR - 45A though. I had an 18ACR with an Adverc controller fitted for about 25 years, worked well except that the front bearing life was poor. The 3/8 in (9mm) blade is rated by Lucas at 35A maximum so anything bigger needs to use both blades Steve
