Boat Van: the roofening

More misc unsorted pics of the roof extension project. Nothing is attached at this point...still deciding how far I'll go before hitting the abort-mission button.

Boat Van

I bought a boat!! It needs some work, so I flipped it over and pushed it onto a large work bench. I'll have a motor and maybe even wings attached in no time. Dad helped me pick it up from the marina. Glad he was there, I had trouble lifting it out of the water and getting it onto the boat trailer.

Jana managed to scrounge a lil' itty bitty delicate anvil for making precision wearable clockwork parts... It's about ~200kg. We got it into the van with a tractor (3 guys weren't willing to lift it), and I got it out with a fork lift. I shoved it on to a pallet at work and left it there. They're worth big bucks here. Maybe Jana will let me take money for it some day, and they can cart it away instead of me having to bring it home and set it up. :D

The goal is to raise the roof on the van by *this* much. 'course I'd do it on the van, and not simply extend the height of the piece on the trailer. (duh) Excuse the crudity of the photoshop.

Van awning and tent

Misc awning and tent kit pics. The van is too tall for the tent attachment, but I'll solve that at some point in the future. In the mean time, the awning is really nice.

Van Gearbox Pilot Bearing Tool continued

Further to the build-post, here is the home made aluminium LDV126/127 pilot shaft puller tool assembly sequence!!

The entire purpose of the tool is to insert the pilot shaft into the main bearing without any applied forces to other parts, and only contacts those two parts.

The final picture shows how it would be implemented during final re-assembly of the gearbox.

A short piece of solid aluminium tube was created for the "workhorse" end of the tool where the most forces will be applied. I am worried about tool failure here.

The remainder of the split component is retained by an off-the-shelf piece of profile tube with an ID/OD of 30/40mm.

M16 thread is wound into the central split part as far as it will go. I am tempted to make another solid collar for this end...but I think the next part (image below) in the tool-set will do most of the work.

80x80mm profile with a 40mm ID. This is the part that comes into contact with the main bearing and will do the "pushing" as the central components do the "pulling".

The external sheath is longer than the internal components so they can slide upwards as parts are drawn together.

A short piece of scrap flat-bar is used as a monster washer across the top of the tool. Keep cranking down on that nut, and the central components are drawn upwards.

The M16 thread itself does not rotate. It is bottomed out into the split components.

This is where all the action will happen when I'm feelin' the success mojo pumpin'. (It was 40 degrees C today...working outside was no fun. Final reassembly will happen later...)

Another custom tool for a vehicle.

Just a preview of another whacky tool build for a specific job.

I only partially solved the gearbox noise the last time I had it out. Partially in that I worked out the problem...the error was in my re-installation...

In order to speed things up, I modified our TINY press at work (Ross's personal press) and made a HUGE version. I've reinforced this one in various ways you can't see. The specs of parts and dimensions should meet the 6 tonne capacity of the bottle jack.

So now I can put the entire gearbox directly into the press, no problem. Last time was a big kludge nightmare. This is so much better.

In order to correct a previous error (and damage to an internal bearing), I need to "pull" the input shaft into this bearing, NOT press them. The difference is subtle. When the input shaft is assembled against the remainder of the drive-train that it's connected to, a smaller bearing that it locates onto between the two parts is crushed if I apply force through the entire gear-train. I need to pull JUST this nose-cone-input-shaft through the heavy bearing, and lightly "push" the remaining gear-train up behind into the back of the input shaft as it's pulled into the larger bearing...easy...

Of course I'd just use tool LDV126 and LDV127 if they supplied it to the public...

Here I've made the part you can see in the top left corner of the workshop manual image.

It's more obvious to identify in your head when you see it cut open like this (as is the original tool, no, the image is not just a cut-away image...the tool is actually split)

Over 40 minutes of reaming/scraping with the tip of a hand file got this to fit snugly. I had limitations on what I could do with the lathe at work as we're not a fitter-and-turner operation.

I've made up the additional collars and slide-tube for the completion of this tool though they're not shown here. I have yet to ream out the second half of this tool part before attempting to use it. ...who knows... I have a few ideas up my sleeve if this fails horribly.

As mentioned in the previous photo, here you can see the reamed out half, and the untouched half that I have yet to work on. There difference is 1.5mm all-round. Quite a lot of scraping required!!
