What have we done this time (R4 F4)

[petak]

While i am waiting for sprockets i have used time to take leftovers from chassis.

Front drum.brakes with brake lines


Rear axle bracket i had to cut out with grinder as it was welded to chassis




Rear brake limiter i just pulled off chassis leg together with brake linea


Some more rust.
Front chassis leg under engine where it is welded to floor. Completely gon inside


Peeled floor panel for side chassis crossmember


This is location where rear brake limiter is possitioned. No more supports inside chassis leg


Other rear chassis leg where rear axle is mounted


After.all.i can not believe that this is chassis that BorgeB and drowe for 500km from Slavonski Brod to Vodice. And that all did not broke on its way to Vodice.

Still left to remove front lower arm support (i can not undo bolts) and that it isfor old chassis

That's some serious rust.. Nice project

Finally got sporckets


From Netherland or better say R-QUATRE.nl

Big sprocket is made by IJS SPAIN. I can see on internet that IJS is manufacturing all kind off sprockets, chain kits, pulleys.
Small sprocket is without any marking.

Teeth are hardened according to Mr Jan-Willem from R-QUATRE.

Now, job with engine can continue!

Mean while front suspension is taken appart.

Upper and lower arm together with vertical bracket are sandblasted and cleaned from paint, rust and body protection.





All bolts, nuts and washers listed and send to galvanising. Made a list of bolts and nuts that need to be changed as they are so much rusted that can not be used again






Rubber silent blocks take off from upper and lower arms.

Prepaired all for painting.

Nice project and again a real deja-vu watching the chassis rust photos

 

[DAA]

Everything very well organized..like a pro!!

 

[petak]

Thank you.
I do not know differently.
I spend more time, writing all down, and taking photos than taking all appart.

Rust is part of game owning an R4

When you are out of idea how to remove bolt in front lower arm (one infront of torsion bar) and you take extra big hammer which do not help and after destoring rubber in lower bush you realise that bolt got "welded" to bush inner sleve because of rust

Lower arm with bush and bolt


Cut out bolt to alove space for grind rubber inside bush with inner sleve from other side bush for comparison.



Here you can see head of bolt "welded" to inner sleve. Left is inner sleve from other side


Fun with rust all the time.

 

[JdeW]

Ít's always fun on every aspect of owning, driving and restoring a R4.
Good job so far and that particular rusted spot is very rare.

 

[petak]

I was surprised also. Other side fell out with slight push.

This project brings another point of how much car can rust.

 

[petak]

Wash primer on front suspension parts.







My paint "booth"

 

[petak]

Little bit to dark but black is always dark.



Now will cure for few days so that paint settles nicely. And then need to joint them back together in front suspension.

Merry Christmas to all

Really nice work!!!

Front legs!. New silent blocks, new ball joints, old shocks (for now)

 

[petak]

First parts are back to (new) chassis

Chassis is lifted little bit not to lay down on ground and to have more access for working around,


Front "legs" and tube crossmember is mounted






And small springs that holds handbrake cables are put on.




Next.....taking apart brakes and rear axle, renewing what needs to be renewed and back to chassis.

 

[Homegrown]

Looks great
Nice to follow your builds

@petak when you bought those Ball joints of the suspension arms, they brings those big washers?

 

[petak]

DAA...i bought it at local car parts shop. I manged to get my hand to TRW brand, and those washers came with upper ball joint together with new bilts and nuts

 

[petak]

Today was front tosion bars day.

Manage to put them really easilly thanks to explenations from Jan Mlinar, one of famous two brother who restore R4s.





And put brackets for front sway bar.
