RUNAMUCK

PNot an update as such, more a musing/potential future upgrade. 

Upon procuring the engine, id noted the front crank seal had been leaking. I whipped the crank pulley off, and much like the pinion seal on the diff, the seal journal was quite rutted/cut into. A speedy sleeve put this back to new. While i had the crank pulley off, i noticed an interesting shape was present.

So i figured  while it was off, it would be a travesty not to machine off the power steering pump pulley, (these are attached to the main hub, not the dampered pulleys that drive the water pump/alternator/AC) 

A nice spigot was machined on, and some holes drilled and tapped to correspond with those nice bosses. This is very hard to photograph in the car.

Quite a while ago, the old boy picked up an Eaton M62 supercharger off Ebay. It came off a USDM nissan frontier truck, with the nissan VG33ER. (The larger version of the single can VG30 which were once common here) i basically told him, i was commandeering it. 

And back when @Vintage Grumblewas a cool kid, he had some SR20det injectors which he kindly gifted to me. 

So in the unlikely event 5his wreck ever sees the road, it wont be too big of a stretch to turn the wick up.

Id made a bet with @Luke that id have this thing drivable in time for an event aaages ago. I lost miserably. Id been sending him pictures of my progress at the time. (Before i had messenger, so by txt at fantastic cost) talking to him the other day, he still had them, and sent a few back to me. 

I manages to squeeze an Ebay special fan between the custom radiator and the front panel.

And i got some pics of the diff too.

620s run an H190 diff, with an aluminium centre housing. However because they were an underpowered light comercial vehicle, they run a 4.6:1 ratio. Great for rally driving, or farm duties. But and absolute fucking nightmare for open road driving. I found a 3.9:1 head somewhere in Hamilton. @mark105 kindly delivered it to camp Rangiwoods for Old school nats 2013. (I might have had the yellow truck that far back) since we were only rolling in a dastun 1200, @Gomaxgo kindly dragged it back down to Christchurch for me in his 6cyl KE70 ' goon.  Because reasons, i finished up using the axle out of the one i parted out for the front cut. As i mixed and matched a few bits, (my handbrake cables were fucked) i discovered this axle was ~15-20mm narrower each side. I had the housing blasted by Blain at FastBlast. And @LowTech powder coated the housing back when he had a powedercoating booth. I swapped the pinion flange over. This also required a hefty sleeve be fitted. Both because the seal journal was bady cut/worn, and because the seal journal was considerably bigger on the 3.9 diff. A lick of paint on the head, and it was glued in. 

Absolutely nobody had a listing for new brake drums. And all of mine were worn out of spec. ROCK AUTO to the rescue. (For all the parts your car will ever need) they were something stupid like $20 each. I gave the backing plates a brush up and paint. And rebuilt the brakes/ew cylinders and shoes. 

(My bench hasnt been that clear for a looooong ass time)

I dont have any pictures, but these diffs use a turbo gay cup and cone arrangement on the axle bearings. You have to set the axle bearing preload by changing shims. (Theres a thrust block in the centre of the side gears that the tip of the axle runs in permanent contact) i fucked these off, and replaced them with deep groove bearings. The deep groove bearing was a few mm narrower than the Cup of the cup and cone. So i had to make a spacer ring as insurance that the bearings could never migrate in and out within that pocket.

The other picture i found was of the gearbox X member i made. Its nothing fancy. The material was kindly donated by @Chris.QCR

The donor front/radiator support panel came from a farm ute, which had had an L16 repower. Some butcher had gas cut the radiator supporr panel out so they could fit the larger L16 radiator. I tidied this up as best i could (not very well) and got a mate to make me a custom Aluminum radiator to fit in the space i had. 

How about that wellside tray i hear you ask?

Well, thats an ongoing saga. 

To start with, i had is sandblasted.  Yep, she was a "bit" rusty.

it must have been left sitting full of geass or the like i think. Anyway, i was somewhat worse for wear. Dropped it off to a mates shop, and he sid this with it.

fast forward to lockdown, and i removed the floor. (It was fuuuuucked)

I disovered this was a new Zealand made tray. (Possibly made in Timaru) they had a different profile on the floor, different wheel tubs, no swage around the whel arches to match the front. I replaced the floor with like for like. And a sheet metal mate halped me make new wheel tubs too. ( @JustHarry grafted these in)  the same mate helped me reproduce the top edges which were also different. (Harry grafted those on too) 

Harry also grafted in wheel arches out of some fucked front guards to mimic what a proper datsun tray would have had.

The tail gate is actually off a proper datsun tray, and its needed quite a bit of fettling to fit. (The NZ tray is a bit deeper)

The tray is still a work in progress. Harry has opted to make new lower sections from scratch, rather than attempting to strighten the mangled mess that was there before.
