  1. Hayter osprey

    A drop of Loctite won’t hurt but the spring washer should be sufficient. Remember the a liquid thread locking compound effectively lubricates the threads and makes it easier to strip or shear the screw so reduce the tightening torque accordingly.
  2. Hayter osprey

    Why, it wasn’t done up tight enough and time and vibration have taken their toll. The retaining “ bolt” is a1” x 3/8” UNF thread hex head set screw . The spring washer is a 3/8 “ single coil spring washer. Flat washer. 3/8” flat steel washer. Key. Standard woodruff key All from a decent engineers merchant or Horticultural / agricultural engineers.

    Don't be in too much of a hurry to bin that lump as those reduction box engines are hard to come by. Strangely enough, a couple of weeks ago, not having seen one for ages, I was brought one to sort out by another "fettler", who had given up on it,

  5. Piston rings

    It is not the removal of the lead that has caused the problems that we have now but the inclusion of ethanol which is inheritly unstable and also hygroscopic . Fuel stabiliser is useful but the simpler solution is to only buy fuel in a quantity that will be used in a month and keep it in 5 litre plastic cans rather than a 20 litre “Jerry can” . The problem is likely to get worse as while UK fuel containes around 7.5 % ethanol , other parts of the world are on up to 13%.

    If they are for a worn engine try a set of Cords. http://www.cordsduaflex.com/whycords.html

    Little blue granules?

    Not quite so, you can retime the ignition using the Before Top Dead Centre figure from the engine spec in relation to the points starting to open. I believe the setting for a JAP80 is 25degrees or 7/64" BTDC. Points gap 18thou and plug 25thou
  9. I'll leave the tap question to someone who knows. What make of magnetic clutch has it got or did Gutbrod make their own? Some electric clutches are self-adjusting while others require setting with feeler gauges to achieve the correct air gap. If it is driving a cutter deck, check the seized or partially seized blade spindle bearings are not overloading the clutch.
  10. Maybe there’s a reason. Rigger boots are banned on many construction sites and I’ve never seen an explanation for that either. Australian construction sites and mining operations insist on long sleeved shirts to reduce the likelihood of skin cancer.
  11. Resistor spark plug or non resistor?

    That’s an interesting observation. I’ve always associated condenser failure to be age related rather than resulting from any other influence.These days I rarely work on anything with an exterior ignition coil , slightly more often on machines with exterior “ platform” magnetos and the bulk of the time on flywheel magnetos. I do change a lot of condensers on the latter group but then they are usually 50+ years old. Not sure. This lot have been changed in the past 15 months or so.
  12. Now what to do with them?

    Exercise caution if you split the box, they are usually held together with steel taptite self-threading screws. Steel into alloy, plus moisture and the passage of time equals seized screws and a possibility of sheared screws; at which point the law od Dr Sodt takes over.
  13. Now what to do with them?

    I now realise why the Hayter connection came to mind. Spicers were used in Murrays and Hayter were the distributors both for red Murrays and similar machines in Hayter green. We used to see Foote boxes in Ariens YT models but I believe that Foote had a disasterous fire at their factory and never got back into production, but the designs were bought by Husqvarna.

    Don't want to start a controversy but the Peerless box referred to will not put up with that sort of treatment for long. All Peerless literature makes the point that the machine must be stationary for gear selection. In my 30 years of running a garden machinery business, most as a Peerless agent, we rebuilt dozens of their MSTs (Manual Shift Transmissions), nearly always as the result of such abuse. If the owner was lucky it was just new selector keys but often also the replacement of the most frequently used gear wheels where the engagement dogs had become rounded as well as the keys. Yes, they were filled with Bentonite grease but this tended to be thrown outward to the inner walls of the casing and dry out there, away from where it was needed. We always used to add a cupful of semi-fluid grease to help fill the voids. Spicer boxes were quite a rarity in the UK and were a product of Dana Spicer the big US transmission manufacturer - more often associated with trucks and off-highway equipment. We very rarely saw a Spicer transaxle but something at the back of my mind says that Hayter was the source of parts etc for their horticultural boxes. http://www.dana.com/aftermarket/brands/brands/spicer-drivetrain

    I don'tthink that you can shift on the move with that box. That said there was at least one ride-on manufacturer who used a manual box with an in-line shift pattern but moving the lever sideways disengaged the drive to the box allowing a sort of shift on the move. Before the advent of lower-priced hydrostatic boxes, Ariens and Snapper used a stepless variable speed transmission consisting of a friction wheel running at right angles to a drive disc. When the friction wheel was running further from the centre it was in high ratio and closer into the centre, low. When it crossed the centre the drive was reversed. Sounds a bit Heath Robinson but actually worked well on walk-behinds and lighter ride-ons. MTD, used and may still use, a similar system on self-propelled vacuums and snow blowers.
