Power steering pump fitted


Prop shaft fitted, This gap look about right?


Fitted stainless strut nuts. Btw, what's the point of those rubber disks that go on the middle shock nut?


Got this to use as a burper for the diff vent

Another 2 days at my mates workshop. Bit of deja vu here as I bead blasted the other set of suspension arms. These will be clear coated and will retain the Mazda bushes as I won't have the money for a full poly bush set for the arms I have already done.

This time I also broke the hubs apart. The fronts had a quick coat of VHT as they are steel.



I also took the rear bearings off. Removing the inner race from the hub shaft was done in seconds with the right tool. Only problem was that the wheel bearings I ordered didn't fit. Looks like I have ti import some.



I also got the right hand header flange straightened out. I then bolted the flange down to a huge lump of steel to keep it flat for tack welding. Hopefully the bloody thing will fit this time.



Lastly, this sexy little knurled adapter (simple things) was made so I can fit the triaxe handle.



No pics, but the last bushes for the diff have now been finished so that can get finally bolted in.

I now have my second set of suspension back from the painters, but I am waiting for my bearings to turn up before I can fit it.

I have finished painting, sealing and sound proofing the bulkhead.



I have also mounted the rad and the intake (temporarily) and it looks like I am going to have to cut a section out of one of the bonnet supports as I can't quite close it.

For the diff breather pipe I have decided to route the hose to the left rear wheel arch and then mount the rubber bulge next to the fuel filler pipe.

A few small victories today.

Washed and put mastic on any rust patches in the wheel arches (not many). Next is to spray rust converter where I couldn't reach and then coat the arches in anti-stone chip.



Tightened the clutch pedal. Not much clearance between the master and head.



There is one bolt in the water pump that is stopping me from fitting my power steering line. It's in the perfect place to make it impossible to tighten the fittings. I am going to fit a flush bolt.

Details, details...

Which reminds me I need to fill the split I made in my bulkhead seam when I bashed it to fit the TPS on the end of the ITBs. I'm planning to MOT mine this week and start driving it again. How far are you from getting back on the road?

Getting "back" on the road...it's never been running :)

I am hoping to get a start up by the summer. I keep thinking that I don't have much left to do then spend all weekend in the garage and come out without ticking anything off my check list.

The biggest hurdle now will be the bay wiring. I've been avoiding it, but I will have to get on with it before too long.

I also need to figure out how I am going to hold the top of the rad.

After lots of pondering I have decided to sell the YT rockers and springs etc, and get Comp Arc Utra-Golds with BTR springs. I have already ordered some YT rubber gasket/spacers. New rocker will come nearer startup time.

I'm with you on that one bud, I'm too the point also where I need to wire the bay and I've been avoiding it like the plague,  it's one of those things though once you decide to get started we'll  get right through it. That PS setup is super clean.

At least you guys can do a decent job now rather the hack job I did to get it running and then suffer some charging issues because I didn't replace the 20 year old battery, alt & starter cables for example. Which apart from being old n crispy weren't really thick enough for my relocated battery anyway.

Yeah, silver linings and all that.

My wiring will be a 2 stage job.

Stage 1: make sure everything I need still works

Stage 2: relocate fuse boxes, battery and relays

I was surprised how hard it is to find water tight relay holders over hear. No fancy Bussmann stuff for me :(.

Check out Waytekwire.com as they may ship international and are a damn good resource for wiring...

Finished the front arches



"Modified" the bonnet so it cleared the intake pipe



"Modified" the rad fan so it cleared the water pump





Fitted the countersunk bolt in the water pump. Just about a perfect fit.

I had a clearance issue when I removed the Power steering pump as the belt wrap meant it was fouling on one of the alternator bolts. Quick fix was to chop a section off the bolt head which of course makes it tricky to get out again! That needs a longer bolt and a bit of sleeving.

I've had a nagging issue when tuning that the O2s start to wander around idle for no apparent reason plus some instability when trying to tune steady state. After much head scratching and diagnosing, yesterday with a mechanics stethoscope. I've decided there's at least one lifter/rod/rocker combo that's just too loud with a distinct tick where the others are more of a mechanical swish. So I've order a new set of lifters, gaskets, bolts etc. to pull the heads again!

At least it was a good excuse to order a 2 part timing cover and fit the other timing, oiling upgrades I've got sitting around. Pity it passed the MOT (that's a UK road worthiness test for others reading) yesterday too.

That sucks. Hopefully there's not any excessive wear on anything.

I think the problem with the bolt happens to the guy I bought the engine from. It didn't come with PS and one of the alternated bolts is missing. Must put that on my purchase list actually.

Attempted to adjust the clutch pedal but found that I don't have enough thread left to make adjustments. I am going to have to cut off the nut from the back of this fitting and weld it inside. Hopefully then I will have a little more adjustment. Of course, I still may not have enough adjustment. I have no idea where the bitting point is at the mo.
