Does the stub axle have the alko 'one shot' nut ? ............... if so then it must be renewed and requires to be done up to 290nm to preload the bearing. 290nm is a fair bit more than 3 grunts and a hernia, I use a 350nm torque wrench.

Excellent. However, you need a wallet warning as dampers tend to be expensive (£60 ish). once stripped snd cleaned the coupling may be ok. Use lithium grease (wheel bearing grease ) for reassembly.

I don't think I will be fishing this weekend 🙄

As in liquids............ water, Oil, Blood etc ?

Yes, that will do the job ........... great when I use it in the HW80 and it hydraulics, I get a tad more than 12ftlb then and a lot of smoke ! 🤣

You really need to drip a 'sticky oil' into the bearing overnight, as WD40 (water repellent oil) and Plusgas (penetrating oil) will both dry out very quickly. Got any 3 in 1 or reel oil handy? , both will do the job fine

Nice area, I have fished Lac Villeneuve-De-La-Raho many times .............

Once I have taken the liquid Norovirus preparation it certainly is ! 🤣 However, I will be pleased to get this sorted ..............

The M&S Chino's are quite expensive unless you are a real skinny git. Matalan and Tescos F&F have a better selection. I have worn Chino's and Cargos for years .................

Vac side effects ............... fooey !!!!!!!!!!!!!!!!! Just been told this afternoon that I have to have a full inspection in order to treat my colitis better (the current medication isn't really working) ........... so, in early May I shall have a session where a camera goes down me gut, and another up me jacksy (had that 4 times in 3 years). I said to the consultant ..... I bloody well hope you do the gut one first ! The actual camera bit is Ok, but the preparation that you have to take 24 hrs before is a real nightmare. The prospect of a mild AZ vac headache seems much more appealing right now ............... At least, I get to see the video as its made !

I dislike like servicing inboards because even the simplest job is usually a major faff due to lack on space. Having said that, I changed a starter motor ( knackered solenoid) on a merc 100 outboard this week and dropped one of the 3 special mounting bolts in the drink. Some judicious work with a fine mesh landing net at low tide saved the day.

That is pretty handy. Beats using a hand pump. Is there room under the sump to drop the oil into a shallow pan or can it only come out the top ? Are those hose clips the sprung wire type ? Awful things I bloody hate servicing inboards 🤣

Tut, tut ....... Tony has already posted in the boat thread ......... Definitely a VW tractor engine, and as usual, not enough room to swing a cat ! Draining the old oil is always an issue, I always use a sump pump if i can, otherwise it is standing on your head undoing the sump plug

🤣 It was more to illustrate that the forces of towing a trailer are definitely not simplistic. However, not the sort of complex math that I would remember without reference TBF the only formulas I remember are those I used to use at work, like calculating my commission, formula based around satellite orbit, and several formulas related to Global positioning (GPS). Google (and others) are a great resource, but you have to know what you are looking for as there is also a ton of shite on there. However, it beats going into the loft to find the right reference book.

Yes, you are correct Geoff, the mass remains constant (because ' it is what it is') but the force is variable, but is there not another scientific name for it ? a 'something mass'

In simple terms ........ It means the quicker you slow with the tow vehicle, the trailer mass becomes greater, thus exerting more pressure on the brakes from the damped over-run actuator.

@JonC, @Andy135 , @suzook12 , @Geoff Here you go............ Decelerating mass is almost a sinusoidal function, which is why it is similar to wave mass calculation. u(x, t) = 2a²·sech²(a(x + 4a²t)) u is the vertical displacement from equilibrium, t is time, x is horizontal distance and v is velocity, sech(z) is the hyperbolic secant function and is equal to 2/(exp(z)+exp(−z)

A stunning performance, but then I guess it had to be given who was in the audience and the guest drummer !

Well, you should be, it is the same formula for wave acceleration and mass, so you can calculate at what deceleration rate is needed to avoid a wave over the stern !

In its most basic form it is really just Newtons second law, which is F= m a. However with a declining acceleration (retardation / deceleration) then the formula is more complex. I will post it up later.

Not quite that simple. The force applied is dependent on the inertia, i.e the faster the rate of speed decline of the towing then the inertia of the trailer is increased. you need to draw up a vector diagram to see the full effect, as it is not linear.

Use external grade plywood (WPB), it will be way cheaper and easier to get.......B&Q, Wicks, etc Also, the ply panel will be bonded together and then encased in fibreglass, so not open to the elements Your engine bolts will be put through holes plugged with sikaflex, and the drain bung will also be sealed with either sikaflex, of drilled oversized, resin bonded, and then drill the correct size.

It is a lot of extra weight to carry, which means more fuel burn and also causes handling issues on some boats with all that weight confined to the bow locker.

No AZ side effects whatever for both the wife and I ............. I am going in for my 2nd dose on Sunday.

Only the right so far, still waiting on the left, but the results are staggeringly good. I think it is only megabyte that has a full house...........
