PRM gearbox control synchronisation

25 August 2013 - 09:16 PM

I have a PRM150 gearbox controlled by a Teleflex 700SS. Having had a gear cable break and replaced, the gear level arm is now very hard up against the stops. The workshop manual states:
With 38mm travel on the Teleflex control this is impossible to achieve, it hits the stops, and did knock it out once. Calculations suggest that the 31mm travel setting at the Teleflex end would not give enough travel.
Has anyone got a similar set up and which holes are used on the control lever and gearbox operating lever? Any advice would be appreciated.

Gas cooker installation

12 August 2009 - 03:20 PM

I am trying to install a Hotpoint HW170LIW Free Standing Gas Cooker. The manual indicated to make the LPG connection to the left hand side. Having now cut the pipe :banghead: to fit the connection on the left-hand side looking from the front, I am having second thoughts about the wording in the manual. It states the following:

"Gas connection
The cooker should be connected to the gas-supply by a corgi registered installer. During installation of this product it is essential to fit an approved gas tap to isolate the supply from the appliance for the convenience of any subsequent removal or servicing. Connection of the appliance to the gas mains or liquid gas must be carried out according to the prescribed regulation in force, and only after it is ascertained that it is adaptable to the type of gas to be used. If not, follow the instructions indicated in the paragraph headed “Adaptation to different gas types”. On some models the gas supply can be connected on the left or on the right, as necessary; to change the connection, reverse the position of the hose holder with that of the cap and replace the gasket (supplied with the appliance). In the case of connection to liquid gas, by tank, use pressure regulators that conform to the regulation in force. The gas supply must be connected to the left of the appliance. Be sure that the hose does not pass through the rear of the cooker touching hot parts."

I have contacted the manufacturer but they will only offer an opinion on the wording of the manual (which they believe implies left, from the rear) rather than explain the reasoning behind the technical requirement.

1. By 'left of the appliance', do they mean port or starboard?
2. Why does it matter for LPG, but not for other gas?
3. Has anyone else fitted a similar cooker, and which way round have you done it?

Thanks in anticipation of any advice.

gas locker location

23 January 2009 - 11:27 PM

Hi, Im looking for advice/views on the problem I may/may not have caused myself. The plan was as per photo to locate 2 small gas bottles in the housing as shown. I am about to install the gas system to a cooker only. (to be checked by CORGI). Whilst I am sure that I can comply with the BSS (the bottles etc. will be below the the opening) I note that BS EN ISO10239 says that "cylinder lockers when closed will be vapour tight to the craft interior openable only from outside the craft". The housing has two external bottom vents. Should by some means gas escape over the lid then no doubt it would drain out through the cockpit vents. The photo is an old one, I am now on the water so am loath to alter my original design. The housing lid and raised water tank lid were intended to, and do, provide ideal access steps for my elderly mother.

Whilst not keen on gas, I was happy with the safety aspect of my intended cylinder location, however ISO10239 has put doubt in my mind. Other views would be appreciated.

Electrozapping fish

03 November 2008 - 08:47 PM

Casually watching from my narrowboat the local angling club electro-stunning pike presumably to remove them from the canal, I enquired as to what power was being used and was somewhat surprised with the answer 10A at 110V in very close proximity to my boat. It crossed my mind as to what effect, if any, this would have on my galvanic isolator.
