1951 Pontiac Chieftain - Gearbox and wiring

Recommended Posts

Very common style of the era to have the numbers set up going around the arc.

The dots behind the needle line up with it- in photographs often I'm at an odd angle to avoid glare or odd reflections. That makes nothing line up due to parallax error, but sitting in the driver's seat the dots line to nicely with the numbers and make it easier to see.

Doesn't quite fit properly but it should do for now.

Considering it's not actually for the car, it's good enough. The connections on the back are the same too.

 

My drum fan died, the bearings quit. Just as summer is getting really warm. Joy.

Fan completely crapped itself. Bearing fell to bits. Poo. It's hot outside.

 

However, I have not been shirking the work; I have wired in the ignition switch and a bunch of other stuff. Reverse lights, starter inhibitor and such. Need to wrap the loom up under the dash.

Put the dash back in and everything is connected the way it should be. Got brake lights, turn signals, headlights. Even the clock works.

Ok so

Everything's wired in, even the fan blower though it ultimately needs to be removed and rewired and greased (lot of work I don't know if I care to do in this heat).

Ammeter registers a charge with battery charger hooked up in place of ammeter.

Horn no longer goes through ammeter.

Took driver's side door switch apart, cleaned it up and now that works, which is nice.

Clock showed I had everything connected up for 40 minutes.

Getting there!

Spoke to the transmission place this morning. They have a brand new old stock front oil pump waiting int he wings for me. I'm going to replace the nose seal simply because that one is 50 years old.

Gotta box up the old pump and send it back as a core return for $50; will be able to order the new pump and thrust washers Friday because SWMBO say that's too much to spend until I get paid with the kids going on summer camp, starting school, band instruments and crap. Hopefully that'll be here maybe Tuesday-Wednesday of next week and I can start putting things back together.

 

In the meantime I'm gonna try see about cleaning up the remaining ancillaries on the engine and reassembling that. I need to try and bush out the alternator lower spindle to fit the bolt that goes through the hole in the timing chain case plate. Got to finish looming up the wiring harness (need to run the wire for the temperature sender and the alternator warning light- the engine side loom is separate from the rest-of-the-car loom so that's good, I can build that and get it cut to length once the engine is in and that gets loomed up by itself.

 

Remaining stuff in the cabin- gotta put the hoses in for the screen wash nozzles, the screen de-mist vent pipes have fallen apart and are no more good and I am gonna put the heater box back in with the valve needing doing because that's not gonna get done before the car's ready to run.

So, last night I went and took a look at the alternator. It's a Delco unit, used in early 60's Chevrolets. However, the lower mounting point does not line up with any of the generator mounting points on the engine so the previous owner just turned it upside-down and mounted the adjustment bolt to the engine and put a thin bolt through the lower eye onto the adjustment arm, which has been bent badly to shape.

This ain't gonna work for me. There's a company that makes an adapter bracket, which is basically just 4 pieces of L bent metal bar held together with a myriad of bolts in a sliding adjustable fashion.

I'm going to attempt to make one as a test. I have a bit of steel bar that is kinda suitable (it's about half as thick as it really needs to be but if it works in test I'll consider shelling out $45 for a proper piece) so I'm going to try make my own that attaches to the original mounting points but allows for the alternator to be correctly lined up with the belt and held in place properly.

interesting :) I was going to say a couple posts back "an alternator in a car from 1951?!"

then I remembered the car had been converted to 12V so they would of had to have changed the original 6V I presume Dynamo?

(very nice work as always BTW! :) )

Yeah, 40 Amp 6V dynamo with external regulator was standard factory fitment.

interesting thats exactly 240W like the Dynastart unit the Model 70 :) (aka a dynamo once the engine has started)

(id of expected the chieftain to have larger unit given the size of the car, was 240W some sort of limit for automotive dynamos or is it just a coincidence in this case?)

Well, with the headlights and radio on, you'd be drawing about 210 Watts so that's about average for cruise. Police generators has higher output, admittedly but that's because they were expected to be idling a lot with lights on.

Bracket almost complete. Needs one more bolt hole drilling through on the rear alternator bracket and the lockwashers putting on.

It tightens up ok. I'm going to assemble things and get it running and see if it squeaks and if it charges well.

      Just about an hour ago I went to start my car up, had Mrs Dustman with me, to go and pick Miss Dustman up from work. Turned over fine but took a while to fire up.
       
      Steering felt heavy. Thought maybe as it's currently -5 + wind chill it's just cold & the fluid is thick.
       
      Started reversing out my bay then I was greeted with:
      "DING DONG" - ABS fault.
      "DING DONG" - ESP fault
      "DING DONG" - headlamp auto levelling not working, contact service.
       
      I shut the car down straight away and we went in Mrs D's Corolla.
       
      Alternator is less than 2 months old, it's a recon unit from Alternator Man in Portsmouth. Hoping the cold isn't killing the battery and it's taking the 'nator out with it (battery passed the drop test last time the no-charge warning came up). Looks like a session with the multimeter after work tomorrow.....
       
      MEH.

      Mrs Dustman has a dash cam she wants me to fit to her '99 frog face Corolla. It came with a hard wire kit as opposed to the usual fag lighter lead, so I might as well make a decent* job of it and hide the wiring completely. Trouble is I can't remember how I got the radio pod out when I fitted the DAB unit she now has. I've also got a few dash illumination bulbs to change so I might as well do it all in one hit while it's a sunny afternoon.
       
      A bit of googling comes up with the US spec dash which appears to be different from the European model, or the 2002-on model. I seem to remember spudging out the dash vents to access some bolts/rivets.
       
      Failing that, is there an easier place to get a switched live from (besides the radio) that doesn't involve destroying the car's interior?

      So, someone posted on another thread a link to an Ebay listing for an LHD '74 Marina listed on Ebay.
      I called a little while ago and talked to the seller, and the story is that it was a good running and driving car 10 years ago, but has been neglected and won't run. I'm debating with myself about whether or not I want to take it on as a project.
      I know these had a terrible reputation when new, but at the same time they're actually legitimately rare in the US. I have seen one in person, and most of the estimates I've seen put the number of survivors at 10-20(although I don't know how much we can trust that).
      There's some definite appeal in the engine familiarity for me with the MGB. I MIGHT have to convert it to a manual though. In addition, there's the issue of having it shipped a couple hundred miles to me. It's listed now for $700...if I could do $500 it might be a make or break for me.
      Any thoughts here on it?
       
      EDIT: The car as it sits now is an automatic. If I swapped the transmission, it would be to a manual. Sorry for any confusion from my incorrect statement!

      After many a long year of occasional contribution on here I've probably got enough old shite on fleet now to do something I should have done yonks ago and start a project thread.
      The story so far.........
      I had an 02 CRV for 6 years and it performed faultlessly as an car taking everything in it's stride. The only issue with it was the 25mpg it returned but as I worked close to home that wasn't an issue. Cue December last year and a new job saw my commute go up from 4 miles a day to 32 miles a day.

      By March I was drowning in green shield stamps so  bought the mighty diesel disAstra from Davehedgehog of this here parish. Shown here on the only off-road parking and only second car parking space I have. The garage contains a few motorbikes so I've always stubbornly stuck to a single car rule so I don't have to move motors to get bikes in and out. More on this detail in a bit.....

      A combination of broken motorcycles needing worked on, a bike trip around the Baltic and work meant that I soon realised that I had no time to prep the disAstra for its MOT  at the start of this month. It wasn't worth enough to pay to have the work done so I decided that the poor old thing would be scrapped in favour of a replacement motor.........
      The mighty Volvo (V70 D5) was purchased from Ma & Pa forddeliveryboy of this parish and migrated north of the border back to it's natural home.

      Three days after being pressed into commuting service the mighty volvo suffered a (badly) sticking caliper and much burning brake smells that had to be stripped and rebuilt before work the next day. Sticking piston at that so the whole thing was off and the brakes had to be bled afterwards. Two and a half hours in the pissing rain was a bit character building especially as the still MOT'd (by 3 days) and taxed (but not insured) astra was sitting on the drive. Decision made, insurance checked and a soon to be taken out Admiral multi-car policy will see me with two cars on the fleet again. I could have used one of the bikes but motorway commuting in the pissing rain on two wheels is no fun. The volvo needs an MOT in december so having the astra back on the road will take the pressure off getting that done if it needs work and the weather is bad.
      And so as the volvo continues to provide daily service, project astra revival starts. Known MOT work needed is frilly arches,  broken number plate and front discs and pads so nothing major. Thus far the arches have been sorted without resort to duct tape.
      After a bit of prodding.......

      And after the angle grinder was let loose surprisingly it was only the return lip that was rotten so the welder was broken out to lash on some roughly cut fresh metal.

      Linished off filled, sanded and primed. Note the use of a farmfoods brochure pulled out the bin being used as masking paper for extra shite points.

      Followed by a near perfect colour matched (*) top coat....

      Well I had black on the shelf and it's good enough to stop the primer soaking up the water so that'll do for now.
      Hoping to get brakes and MOT sorted in the coming week so more to follow soon (hopefully).
