I,m at present rebuilding my severly damaged ZPJ4 engine & have checked & rebuilt every nut & bolt on said engine... But I have a problem... on putting the front rocker assembly together there are 2 x 6mm cap screws that hold the ends of the shaft to the base plate... on my set up these bolts go straight through the shaft... I think there are 2 half moon washers missing... the same type as fitted to the other rockers... Has anyone have a Technical bullitan that shows the correct installation for these shafts.

Cheers Eddie.

Hast du WhatsApp?

Dann kann ich ggfs behilflich sein.

 

Ich habe solche Motoren öfters zerlegt und wieder zusammengesetzt.

Via PN 

No Eric I am not... but if you send me a friend request on facebook... you can send me a photo or other information via.that... & I can do the same.

Cheers Eddie Wynne.

Eric, I,ve repaired the rocker shaft & have now completed fitting the cylinder heads to my engine...I installed the front timing chain as per the Russek manual then turned the engine 240 degree & installed the rear timing chain...the engine is now locked...as per the manual both camshafts are the same...so If I,m timing the front head at number 1 at TDC on the firing stroke...I must now set the rear head at TDC on number 4 stroke...I found a Peugeot site which says the engine must be turned 360 degree & then a further 240 degree to set up number 4...this makes sence...if I just turn the engine 240 degree I,m making number 3 at TDC...is this correct the engine must turn 1 revolution then 240 degree.

Ganz wichtig, du musst 360 +240 Grad anwenden. Die 1 in der Reparatur steht für eine komplette Umdrehung . Ich habe das Anfangs auch verkehrt gemacht.

Thank you for letting me know.

Cheers Eddie.

Für diese lustigen Bildchen aus Y3-Zeiten braucht man in der Tat Vorbildung. Das ist nix für Noobs. Ich versteh da oft auch nur Fragezeichen.
Die Mechaniker waren ja wohl alle auf Weiterbildung. Wenn du es einmal erklärt bekommen hast, dann weißt du auch später wieder was damit anzufangen.

[...] Russek manual [...]

Hi Eddie,

never heard of that before.
In case you are not aware, there is documentation from Citroen available on the interwebs: http://ckc.dk/cgi/catlist?

Where in the UK are you located, if I may inquire? I spent three years at the SW coast, Bournemouth to be exact. Stunning place, splendid times, wonderful people. Sweet memories of times long gone.
And not a single XM spotted on the roads. I did stumble across a Trabant though (a car that has been produced in Eastern Germany, we like to call it "Pappe" - cardboard).

Wishing you the best of luck with your rebuild.

Cheers,
Michael

@schwinge
Dss Peter Russek Pocket Manual ist gar nicht schlecht.

Alle Infos kurz und meist verständlich. Nicht viele Bilder wie im Haynes, aber dafür weitestgehend fehlerfrei (habe zumindest keine gefunden). 

 

 

Thanks for the replies guy,s...but the instructions in the Russek manual with regards fitting the timing chains to the ZPJ4 engine are WRONG....timing the front or right bank is correct...your setting the cam timing on cylinder number 1 on the compression stroke...the problem is...as the camshafts are identicle...unlike the ZPJ... you must now set the rear or left bank at number 4 on the compression stroke...because number 4 is the last cylinder to fire in the 720 degree cycle you must turn the engine 600 degree to set the timing chain & NOT just 240 degree as the manual says.

Michael I live in Newton Abbot just along the coast to where you lived...origonally from Edinburgh.

Citronabx, What is the manual you were using to send me those photo,s.

 

This is the original workshop manual. A copy can be found here:

Scroll to "MAN008931". Just a headsup, this particular one is in French. 
Within that pdf, find chapter XM 122-0/4 (page 306ff).

Genau so ist es auch in der von mir verlinkten deutschen Peugeot-Anleitung auf Seite 57 für den ZPJ4 beschrieben:

"Hinterer Zylinderkopf....Kurbelwelle EINE UMDREHUNG PLUS 240° im Uhrzeigersinn drehen"

Eine Abbildung gibt es dort aber nur zum ZPJ, mit angegebenen 240°.

This is also described in the German Peugeot manual I linked to on page 57 for the ZPJ4: "Rear cylinder head...turn crankshaft ONE TURN PLUS 240° clockwise." However, there is only an illustration there for the ZPJ, with the specified 240°.

Joschko
