Stock Bumpers refurb



Just a quick post today to bring Gus's blog up to date so far.


The cheap aftermarket chrome bumpers had not done well this winter




Managed to find a set of original stock bumpers for sale via Facebook not to far away and very cheap

So popped up to collect.

Spent a day cleaning the insides of surface rust and rust killing and a good covering of POR15. Then tacked the original chrome.

Considering these are 48 years old the original German chrome is so so much better.

Good coating of Chrome polish and a little bit of foil they came up perfect.




Next the bodywork!


New Engine Fitting

Fitting new Engine

In my previous post I wrote a post on building Gus his new engine from mostly secondhand parts.

See the previous post below or here:


After the build of the long block it was time to remove the old engine, swap over auxiliaries and refit the freshly built engine.

Sounds simple BUT I ran into a few problems along the way.

Engine Removal


After driving Gus onto the ramps on the drive the process of removal began over a few evenings.

Standard engine removal process followed.






Engine out!

Engine removal process was simple. I built up a trolley dolly which fits onto the jack so its simple to hold and simple to maneuver about.

First problem / Issue was that my newly Trolley Dolly worked great to lower BUT its additional height under the jack means that it is too high and the engine cannot be rolled out under the bodywork. My Ramps just are not high enough.

So I managed to remove the engine from the trolley and drag it out under the body work.

Lots of manhandling and tipping the engine later (had to remove carb and slide it out under the holes which the exhaust go through under the rear valence)

Finally the old engine is out

Old Engine Stripdown

After removal I decided to strip down the old engine auxiliary off.

Lots of parts and easy to remove. I really love working on VW air-cooled engines!


Trolley Dolly makes a nice seat in the sunshine









Done





Parts parts and more parts!



A few "spare" nuts found!


 

Cheap aftermarket chrome crap!


Found a few issues.


Cannot believe the fuel hose has cracked. I replaced ALL fuel lines with NEW SAE R9 Fuel hoses 
(Purchased from reputable VW parts dealers 10 months before!

PLEASE PLEASE check all your VWs fuel lines even if new!



Moving new engine - Simple - NOT

Our house has to be the worst case  to work on cars! It has the following points all which have conspired to make it the worst:

  • I have a large workshop at the furthest point away from the road & driveway. Great.
  • It has 8 flights of stairs between the workshop and the drive
  • Two grass lawns
  • Brick paving & slabbed patios
  • 2 Gates
  • Side passageway approx 1m wide between house and driveway
  • Sloped driveway
  • Large concrete driveway enough for 3 cars. Great
So I needed to transfer the new engine from the workshop to the drive overcoming all the obstacles in my way.

So in an A-Team moment I bought a sack truck and Built a RAMP!

Trolley £28 B&Q


The Ramp!

After a little construction and clearing the way, the eldest son & I managed to man handle the new engine to the driveway!

New engine on Drive & old engine in workshop.

New Engine buildup

Onto the build up stage. So it is just a simple process of building up the long block with ALL the auxiliaries.



Job done!

Took me a nice sunny afternoon and a few cups of tea!

Fitting New Engine

Started to fit the new engine.

Oh dear.... This is where it all started to go wrong.

  1. Went to re-fit old engine clutch  - Too big
  2. So new engine must be 180mm clutch.
  3. Ordered 180mm clutch - 180mm Too small
  4. Measured flywheel on new engine - 200mm
  5. Checked original engine clutch diameter - 210mm??
  6. Very confused. So checked flywheel teeth & Diameters
  7. New engine has 200mm Clutch with 109 Teeth!


My understanding was that you have 12V and 6V flywheels 

6v=109 teeth 180mm
12v=130 teeth 180 & 200mm

BUT I have a 6V / 200mm /109 teeth flywheel!

Also I don't have a clue what flywheel was fitted to original engine (210mm??)

I found out there is a 1 year when a Type 2 Splitscreen in 1967 was fitted with a 6V 1500 cc (H0 1966-67 1500cc)

VW where worried about the additional power of the engine size increase they fitted a bigger clutch diameter but as it was still a 6V electrics they kept the 109 tooth. These engines also used a non stepped crank shaft without O ring, so swapping to a 12v flywheel was out of the question.

So this was a problem as I have a 12V starter motor & Bush and I needed to swap to a 6V with an adapter bush.

I managed to purchase a cheaper 200m clutch and a 6V starter motor was donated to me by a nice guy from a forum (Thanks TonyGhia)

Fitted the 6V starter motor running from 12V supply spins like a banshee but good enough.

Once this was overcome I fitted the engine and connected everything up.







Guess what? 

He started up first time once fuel had got through!








New Engine Build

The adventures of Gus and the engine build

Background:

Gus the 1968 beetle has been with us for over 1 year now and he was used for a daily driver since then. The long cold winter has taken its toll on him. Rust body due to the salt and poor spray paint by his previous owners.

After a year of driving he needed some TLC. The engine which he came with had unacceptable level of end float and after daily use it was starting to sound rough and so I thought I would build up a "spare" engine to have in reserve just in case.

The Purchase:

 I was on the look out for a cheap engine as I don't have much disposable cash. So after a few weeks looking on e-bay I found something which had no bids and was located locally.

I thought it was worth a punt as worst I can use it as an exchange for a reconditioned engine if required.

For £100 it is a 1300 engine complete except the Pistons & Barrels.

So after a business trip to France I arranged collection.

The Cleanup

I got the engine back and started to clean it up.







Upon initial inspection all looked okay. Some slight end play and years of crust and crud.



Removing the flywheel "ghetto / guerrilla style"





Half way

A few days of wire brushing and plenty of elbow grease the case started to look okay. Not going for spotless but just wanted to get enough off to start the rebuild and be able to see any oil leaks.



Clean Enough


Rebuild Parts Required:

So the engine came with a pair of DP heads. Not in bad condition BUT the usual crack from valve seat to spark plug and general signs of poor condition. So these went in the pile of hoarder spares I have. I will also need enough parts to build up the long block including oil cooler and fuel pump. 

I have two rules when it comes to parts.

Rule 1 - Stock Rocks
- Original Stock VW parts either NOS or secondhand are best. The fit and are much better build quality than all the cheap aftermarket parts.

Rule 2 - Bargains
- I hate paying full price and the "scene tax" so always on the look out for cheap. That's why I like e-bay :-)

The shopping list started to grow to build up to long block:
  1. 1600 DP Cylinder heads
  2. 1600 Barrels & Pistons
  3. Doghouse oil cooler
  4. Doghouse oil cooler adapter
  5. Pulley wheel
  6. Breast plate tinware
  7. Under Barrel tinware
  8. Rocker covers
  9. Rocker cover clips
  10. Gasket kit
  11. Flywheel oil seal
  12. Flywheel shims
  13. Spark plugs
  14. Push rod tubes
  15. Fuel pump
  16. Oil Pressure switch
Managed to get secondhand, original stock parts of the following

1600 DP Cylinder heads
Doghouse oil cooler
Doghouse oil cooler adapter
Pulley wheel
Breast plate tinware
Rocker covers
Rocker cover clips

I had to buy these parts.

1600 Barrels & Pistons
Under Barrel tinware
Gasket kit
Flywheel oil seal
Flywheel shims
Spark plugs
Push rod tubes
Fuel pump
Oil Pressure switch

Managed to get the barrels & pistons cheap at just £80 new as they were returns as they had a bent fin! Bargain!

The collection of parts started to assemble:



Cylinder head build up:

I had to check and recondition the secondhand cylinder heads.

They where not in bad condition. Checked sellers photos and asked questions. and managed to get a low offer accepted (2 original stock heads for much less than the price of 1 new aftermarket one)

First job was to clean and remove valves



Lovely gold color!

One issue that I found was that one of the heads came with an "old" spark plug. It was really old and why did they remove all the others and leave this in.

Went to remove it and it was completely seized in! Looked like it had been over torqued and also had gone rusty. That's why there cheap. Could have got annoyed or see it as just another engineering challenge.

The worst case I will have to "helicoil". Not ideal but that is the worst case.

Soaked in penetration oil. Then removed carefully. It was tight! but came out with little alloy from the threads.

I thought I would re-tap the threads to ensure that they are all clean and sound.

Found a spark plug re tapping tool.

After the re-tap tested the threads and all went in really well. I think this tool is great as it cleans out and up the threads. Good one to have in the tool kit.

After removal of valves I spent many hours cleaning up and removing years worth of carbon. Then leak checked and reground all valves and seats. Simple leak check of filling each port with solvent and waiting to see if any leaks. A few leaks but all sealed after a good grinding.




A little leak before grinding in valve

 

 Good clean & polish!


Not going for a full port and polish, just a stock engine so clean is enough.




Cleaned and reassembled.


The Build:

All parts are ready and prepped so the build began.

Flywheel & End play first






Shim shim shimey

Then Moved on to Barrels & Pistons









Not forgetting the under tinware!

Note: Now you can see the bent fin. Its not on the sealing area.

Heads on next.









Rocker and Roll


Painted pulley.


Rocker Covers


Fuel pump and oil cooler fitted


Finally completed the build.

Engine Test

Did not want to fit the engine without a good test. Did not want the hassle of putting all fuel and ignition system on to fire it up.

Just wanted to check compression and oil pressure and see for any leaks or issues.

So got my old gearbox and starter motor and hooked up a ad-hoc test bench



Turned engine over and checked compression. Hooked up oil pressure send and checked for oil pressure.

All good compression spot on each cylinder at 120psi on all 4.

Learning:

A little bit of scavenge of original stock parts and bargains can build an engine.

Its just a matter of hard work cleaning, checking and reconditioning to use secondhand parts.

So I added up the bills and the Long block came to £350 and accessory addtional parts (fuel pump, oil cooler etc) cam to £100

So for £450 I have built an engine! Its not the best but better than I could afford and half the price of a "recon" engine

So it was now on to the next phase fitment.
