Can you get such a thing for bikes this age?  the cups are just cut into the crank so it would mean a crank replacement.

yeah you'll be able to source that stuff, but if you dont care then dont haha. most of my bikes get the grease burnt out of the bracket, filled with grinding dust, and run like shit for ever with no troubles.

Cool, yeah I have the side in me which says replace replace, but then there's the "it's just a bike you'll use once in a blue moon" bit, I'll get the bearings and see how it feels, it it pisses me off then I'll get a new crank/cups.

 

Leaving it looking rusty has been a challenge for Mr. ooh shiny bead blast it, chrome/paint

Went to Saeco bearings and ordered some new ball bearings.

 

For future reference in case anyone needs the info:

Pedal Ball bearings are 5/32", 11 balls per cup.

Steering ball bearings are 5/32" , 16 balls per cup

Crank ball bearings are 1/4" 9 balls per cup

 

Will update with wheel bearings when I get to them unless someone else still has the info?.

 

Grease, I'm using a Lithium Complex EP2 as that's  what I had in the shed,

another wee step closer, some of the detail.

Dusted off the drawing board, been a while and no compass for drawing radius's, but an old radio knob came to the rescue.

it probably could, it runs on jet-a1,avtur is jp-1 which

no longer exists along with jp-2,3. Jet-1 is the same as jp-8

we run avtur FSII (icing inhibitor). and fuel samples every day to check for water in the tanks almost always come up clean, but that fuel still gets wasted.

 

you could probably get a pretty steady source of jet -a1 if you made friends with who ever does the samples at the civilian airports.

How much fuel do they sample? It was only 100mls or so back when we were doing oil and fuel samples, but some things might have changed sine then.

I don't use a heck of a lot tbh. Still... free fuel is free fuel!

meant to be 500mls from each sample point, and on the herc thats well over 10 sample points. sampling 100mls runs the risk of if there's serious water contamination, that you might draw 100mls of water and it will look like 100mls of clear fuel!

Sounds logical, Just being nosey, are you (or whoever) doing the tests onsite or do you send them off to a lab for testing? We used to use SGS, cant remember who it was before them, I think it was our own labs back in Australia.

LOL when I was training we would drain like 50ml and then it would get hiffed into the grass.

If we drained 500ml from a tomahawks tabk we'd have had to go refill again lol

fuel drains are a daily occurrence during preflight checks. we literally drop 500mls from each point, swirl it around (this causes a vortex that forces the heavier water to the bottom) and check for water. 

 

oil samples are done via a SOAP (spectrometic oil analysis program) and is done offsite i believe, but im not sure, all i do it package it up and send it off to the tech cell.

its all relative. a tomahawk cant load 52,000 pounds of fuel onboard

I watched that a while ago and had a chuckle at it.

One thing I didn't anticipate is how loud this thing is and the extent of how far very hot air extends. certainly not going to be an every day commuter.

 

Put the engine on a test rig and had a couple of trial runs up to 90Krpm, loads of fun!

The Mrs now knows about the secret jet bike plan, that's for sure.

pretty sure the neighbors do too.
