Dollywobbler's Invacar - Ongoing

Recommended Posts

this one, although your right the crack I normally think of as the crack in your hard top is the one on the lower left

it may be I just have never noticed the crack going round the side before

(I did try and check some older Photos I have of TWC however none of them are from that side so I cant tell if its grown or my mind is just messing with me)

Get some Fibral, P40 (or similar) and slap it on from the inside.  It's a fairly thick paste so easily managed and will stay where it's put.  No need to have anything visible from outside, but it will help restore the strength of the area to stop the crack spreading and help keep the weather out.

This stuff.

Still messy, but it's so much easier than messing around with separate matting and resin and is pretty user friendly.

I found (far too recently!) that the best way to get things nice and smooth was actually to just use disposable gloves and smooth it over by hand, especially if you're working inside a tight curve or recess which makes getting tools in difficult.  Wish I'd worked that out a few months ago.

For small cracks and holes it's more than adequate.  While I've not done actual industrial testing, I've abused some of the repairs I've done with it and ascertained that it's more than strong enough so long as it's well keyed to the surface.

Well squidged into a hole or crack in a panel it's plenty strong.  Probably stronger than the rather low rent fibreglass these bodies are made of to start with!

The thought did cross my mind that you could only patch the cracks on the “hidden” side to reinforce them and prevent them growing whilst preserving the patina and completely negating the need to bugger about with filler, sanding, paint and all that other malarkey.

I’m also pleased for you that the spat spark plug was a relatively easy fix. They can be proper pains, hence why the spark plug in my lawn mower is currently held in with Araldite and string.

happy to see another TWC focused video I enjoyed it very much :)  (and the NMR one too! :) )  I also enjoyed the bit where @dollywobbler was explaining what TWC was etc and I like to think you where thinking to yourself "ok what did LBF say again in that ramble of his 2 weeks ago? I better get it right or he will complain again!" :mrgreen:

very happy to see she is happily cruising at 55-60Mph, did you get a chance to look at the distance of the pulleys? according to the workshop manual it should be exactly 10.25 inches between the centre of the 2 pulley shafts

as seen in the manual and in this letter to all approved repairers to RTFM! (it seems people where trying to adjust the belt tension by eye and not actually reading the workshop manual. its said at the start of the Model 70 there were quite a few transmission issues, a lot apparently down to the fact that most repairs had no experience dealing with a CVT system)

Nice to see her out and about again.  Just watching the video now as it's the first real chance I've had.

Definitely worth giving setting the belt by distance as a test.  The reduction in "thrashy belt" noises at speed was quite noticeable on TPA when I did that.

Still quite gutted I couldn't make it down...I was still half toying with taking TPA down, though once the wheel stud went ping that was the end of that.  She's definitely going to be there next year if I have my way...

DHSS Workshop Manual For The Model 70 Three Wheeler(OCR).pdf

 

for @dollywobbler as mentioned at the FoD, here's the workshop manual scanned in high quality colour by @Zelandeth and then OCRed by @1970mgb :) (that means you can search it! although as the DVLA database clearly demonstrates, OCR is not perfect)

(I was holding off making this public as I know Zel said he wanted to to tweak a couple things and scan the workshop manual again, but given how busy he is currently I think its best I share the copy I have and then I can update it when Zel produces his final example :) )

for what its worth the bad quality Manual we had before hand Does mention the 10.25 inch Pulley distance thing so I will leave you with a picture of this Tippen delta :mrgreen:

Given I didn't have the manual with me, no I didn't.

well now you have something for more video content at least! :) (I did notice you had a couple printed sheets of the manual in the video, did Elmsleigh Invacar print those off for you? I would love to have a rummage around the place and see what they have! I do wonder if a workshop manual for the Invacar Mk12 and such like also existed)

(I do wonder what the procedure is for tensioning the chain would be, maybe a Saab owner would know!)

for future reference when out and about id recommend saving the manual to your phone or such :)

It's probably only applicable to transmissions that are fully dry of oil when new or rebuilt rather than an oil change situation .

good point :)

but given how the diff "oil" was mostly water, it probably would not be a bad step to do just to flush out any crap and stuff from the chain case that may have accumulated over the past 47 years :)

Meh. It sounds like it's going to die at some point anyway. Not much point worrying now.

In other news, I got confused between cars, and the Invacar does NOT use the cathedral-style connector for its indicator stalk. That must have been the Fox. I ordered a selection of Lucas stalks as a job lot, and none of them fit. Yay! So, I've tied the stalk to the handlebar for now, so there's no main beam. That'll do. With New Zealand looming, I can't justify any further expenditure on the fleet at the moment.

Taking the Invacar on a road run on Sunday. Weather forecast is entirely terrible. Maybe I should have refitted the demister...

Indicator stalks seem to pop up now and then on eBay, at least we know the proper Lucas part number now.  This is what you need: 39732.

id still attend to it, you don't want it to get worse :) 

and while we both know where there might be a spare gearbox, I would advise lunching your gearbox given the general scarcity of Model 70 bits!

 

sorry to hear about the connector mishap I did notice the Connector on REV was different than the one you thought it was at the time

this almost looks like it but its not "cranked" like the Model 70 ones are

I wonder if thats what the J means

(but searching 39732J does not pull anything up but removing the J gives me results)

 

so this IS the sort of switch/connector your looking for then? just so I can keep my eyes peeled :)

Here's something to cheer you up, not the Marshalls bodied Panther Cub, the Invacar sneaking into this picture I took around 1970 in Portsmouth.

      Well I've been meaning to sign up here in forever, but kept forgetting. Thanks to someone over on another forum I frequent poking me about it recently the subject was forced back into my very brief attention span for long enough to get me to act on the instruction.

      I figure that my little varied fleet might bring you lot some amusement...

      So...we've got:

      1993 Lada Riva 1.5E Estate (now fuel injected, as I reckon the later cars should have been from the factory...).
      1989 Saab 900i Automatic.
      1987 Skoda 120LX 21st Anniversary Special Edition.
      1985 Sinclair C5.
      2009 Peugeot 107 Verve.

      Now getting the photos together has taken me far longer than I'd expected...so you're gonna get a couple of photos of each car for now, and I'll come back with some more information tomorrow when I've got a bit more time...

      Firstly...The Lada. Before anyone asks - in response to the single question I get asked about this car: No, it is not for sale. Took me 13 years and my father's inheritance to find the thing.


      Yes, it's got the usual rusty wings...Hoping that will be resolved in the next couple of months.

       






      Next, a proper old Saab. One of the very last 8 valve cars apparently, and all the better for it. I've driven two 16v autos and they were horrible - the auto box works sooooo much better with the torque curve of the 8 valve engine. Just wish it had an overdrive for motorway cruising...









      Next up a *real* Skoda...back when they put the engine where it belongs, right out the back. In the best possible colour of course...eye-searingly bright orange.







      Seat covers have been added since that photo was taken as it suffers from the usual rotting seat cloth problem that affects virtually all Estelles.

      Then we have possibly the world's scruffiest Sinclair C5...



      Realised when looking for this that I really need to get some more photos of the thing...I use it often enough after all! We have a dog who's half husky, so this is a really good way of getting him some exercise.

      Finally - again, I really need to take more photos of - we have the little Pug 107.



      Included for the sake of variety even if it's a bit mainstream! First (and probably to be the only) new car I've bought, and has been a cracking little motor and has asked for very little in return for putting up with nearly three years of Oxford-Milton Keynes commuter traffic, before finally escaping that fate when my housemate moved to a new job. Now it doesn't do many miles and is my default car for "when I've managed to break everything else."

      I'll fill in some more details tomorrow - I warn you though that I do tend to ramble...

      Hullo,
       
      I'm a masochist from Leeds who is running two rusty, worn out Triumph Dolomites as my only transport in rural Aberdeenshire. You might recognise me from various other forums and Facebook groups. Realistically I need to buy a modern car of some sort, but instead I find myself looking at £300 Citroen BXs and Triumph Acclaims on Gumtree and thinking "yeah, that'd fit right in with the rest of the broken cars I can't afford".
       
      On to the cars, the main attraction being my 1976 1850HL "50 Shades of Yellow" that I bought for £850 and is currently my daily driver, here is a picture of it before I sanded off some surface rust and sprayed it badly in the wrong shade of yellow with rattle cans:
       

       
      Within a month of purchase I managed to plant it in to a steel fence backwards after a botched gear change on a wet roundabout and ruined the N/S rear wing, although judging by the other dent that's packed with filler it looks like somebody had already done the same. I also managed to destroy a halfshaft and one of my Sprint alloys (good for an extra 15hp) in the incident, so now it's sitting on it's original steelies but painted black (good for an extra 5hp).
       
      It's only broken down on me twice. once with some sort of fuel delivery related problem which may or may not have been an empty fuel tank and once when the thermostat jammed shut and it overheated and blew out some O-rings for the cooling system. It has recently developed a taste for coolant and oil which is rather annoying, although it's done 89,300 miles which is about 80,000 more miles than BL engineering is designed to last, I'm keeping my eye on eBay for replacement engines... 
      I tried to keep ahead of the rust a bit by rubbing down the arches and re-painting them, but apparently rattle can paint isn't great when you are spraying it at -5C, it also highlighted how although my car might have been Inca Yellow in 1976 it's now more of a "cat piss" sort of shade. So I ended up with the wrong shade of yellow which has rust coming back through after 5 weeks. Did I mention I'm incompetent?
       
      The other car is the first "classic" car I bought, so I can't bear to sell it. It's a '77 Dolomite 1300 and it cost £1400 (about £400 too much) and has been nothing but a pain in the arse:
       

       
      It looks much prettier (from 100 yards) but that's most due to the darker paintwork hiding the rust. It lives a mollycoddled life in my garage, where it somehow still manages to rust, and is utterly rubbish. 0-60 is measured on a calendar, top speed is 80ish but at that point it uses more oil than petrol, it rarely ventures over 50mph and if you encounter an incline of any sort you can kiss that sort of speed goodbye, along with about £20 of 20W50 as it vanishes out of the exhaust in the form of blue smoke.
       
      One of the PO's had clearly never heard of the term "oil change" so it developed into brown sludge that coated everything internally with the next owner(s) blissfully pouring fresh oil on top of it. This lasted until about 600 miles into my ownership when there was muffled "pop" from the engine bay and the car became a 3-cylinder. The cause was catastrophic wear to the top end causing a rocker arm to snap:
       

       
      As this was my first classic car I'd assumed it was supposed to sound like the engine was full of marbles, it wasn't.
       
      I put the engine back together with second hand bits declared it utterly fucked and promptly did another 5000 miles with it. After about 3500 of those miles the oil burning started, valve seals have gone so it's been relegated to my parent's garage as a backup car and something to take to local car shows as the 1850 is now embarrassingly ugly. I'm keeping my eye on eBay for replacement engines (deja vu, anybody?) Oh, I also recently reversed it into a parked Ford Fiesta and royally fucked up the rear bumper, rear panel and bootlid. Did I mention I'm incompetent?
       
      There have been two other cars in my life. My first car, a 2008 Toyota Yaris 1.0 an it's replacement a 2012 Corsa 1.4T. I didn't really want either of them, but it's a long story involving my parents and poor life choices. Ask if you want to hear it!
       
      So that's a brief summary of my current shite. If you want more pictures or details of anything do say as I've got photos of almost everything I'd done with the cars.
    • By strangeangel
      I thought I'd start a thread for this as I'll probably end up asking all sorts of questions, given that this is my first 'proper' Citroën.
       
      So... the ground clearance lever won't go all the way to the highest setting (all others work), which is bad 'cos the book says I need it to do that in order to check the LHM level. It feels like something's seized, so I don't want to force it. Any ideas for a plan of attack would be much appreciated.
       
      Next up are the wheels. I now have a set of 205 pepperpots that have just gone off for powder coating & I need to get some tyres for them. The handbook says the car should have 165/70R14s on, the wheels came with 185/65R14 on. Any thoughts about what size I should get please? Cheers.
