750 K2 Strip & Rebuild - help please
Nurse Julie:
Zinc is correct for a 750K2 .
Lobo:
Can anyone advise how to separate the chrome cap from the rest of the gubbins please? Tried heat + gentle prying - to no avail.
Not esp happy to try a threaded bold through the lower cap holes to push against the chrome top ….
(Wanting to re- gold passivate the lower cap)
Ta.

Hi Ash,
Wrt to my hardened airbox rubber and Wintergreen - sorry for the late reply….
Oddly, only 25% (circumferentially) of one rubber has mummified, and whist heat would soften it, within minutes it’d be back to its new norm. I then put it in a jar of 25% Wintergreen oil + 75% isopropyl, and have left it there for weeks. It’s much better, but still retains a little hardness. Most surprisingly it’s shrunk in overall size - to the point of being unusable.
Can’t work it out, OEM and the other 3 fine. It’s defo the runt of the litter…
For the price of a single replacement I’ll skip trying to source Reofos 50 and call it a day 🙁 . Thanks nevertheless!
Cheers,
Simon.
Lobo:
A bit miffed last week as Autosol polish removed the Gold Passivate from the dipstick and Voltage regulator….
Managed to separate the dipstick components by drilling a 5mm hole in the circumference, and then tapping in a blunt 5mm grub screw to prise the chrome cap off. Worked a treat.
Dipstick innards + VR cap zinc planted and passivated - pleased with the results.
Lobo:
This restoration is getting deeper and deeper 🙄.
Anyways, because I’ve now decided to powder coat the frame, the loom is out, and looked a bit grubby. So, no dishwasher for me, but rather the (heated) Ultrasonic cleaner … and it’s come out like new. The question now is… will there be extensive water / damp in the loom runs and should I de-construct / rebind with fresh tape?
In my gut I reckon I should, as years ago I renewed a 400F loom, and kept the old (original) for spares. What shocked me was finding splicings within that loom, simply twisted together… no solder… nada. If the 750 loom has the same, well, I’d rather fettle it now.
Thoughts…?
Edit - I might have answered my own question since studying the circuit diagram & noting numerous internal splicings, primarily in the live (Black) and Earth (Green) runs. I guess if the first I come across is soldered / crimped I’ll stop; otherwise it’ll be a full re-sleeving / making good splicings.
