Strip AAZ to bare engine, head and block, good time to replace cambelt and tensioner and check crank pulley and crank for wear.[see note] Fit JX sump and oil pick up pipe without windage tray [see note] Use AAZ injection pump, modify throttle linkage. Use T3 Diesel (CS,KY, JX) throttle cable. Small hole in engine lid, probably about 15cm's by 10cm's and about 15mm increase in height. Use JX exhaust manifold.[see note] Use JX exhaust. Use AAZ turbo, change attitude to suit JX exhaust manifold.( you can use JX turbo if required)[see note] Manufacture oil feed pipe for turbo. Use JX exhaust and mounts. Use T3 Diesel clutch.[see note] Fit spigot shaft bearing to crank (Part of Brickwerks kit) Fit block bung to back of cylinder block (Part of Brickwerks kit) Fit «Cut to length» Oil return line from turbo to sump (Part of Brickwerks kit)only for KKK turbo's, not Garrett) Use JX airbox and piping to turbo, relocate airbox to behind LH light. Use JX water housings for cylinder head. Use AAZ waterpump to head rubber hose as the JX one isn't long enough, block the spare end. Use AAZ inlet manifold, JX and AAZ ports are different shapes, if you match port the JX manifold to suit the AAZ head then in my opinion you aren't left with sufficient material to create a good seal. Use which ever alternator/belt set up suits you, they are interchangeable. Use (KY,CS,JX) Dipstick [see note]
Notes.
Using the original AAZ exhaust manifold and turbo in it's AAZ orientation results in oil not being able to drain from the turbo, engine will run on it's own oil and self destruct, A lesson I have learned from the mistakes of plenty of others. Using the AAZ turbo and exhaust manifold will mean you have to make an exhaust to suit, any smaller diameter of the exhaust pipe will result in high EGT, therefore a shorter engine life and less performance.
Once done, fit new oil filter, fill engine up with 4.5l of oil and run, once run then re-mark dipstick to new level. If you don't the level maybe too high, the engine may smoke or run on it's own sump oil, and possibly self destruct.
215mm clutch will be fine for standard AAZ in a T3, if you start tuning, then it won't be strong enough and you will have to find an alternative method. The clutch from any of the T3 Deisels will do, they are the same.
Don't use the windage tray. It increases the width of the gasket as it were, then when you try to get the bottom bolts from bellhousing to sump they won't line up. Leaving the sump loose while fitting the engine, I don't see how that would work as the sump is still that little bit further away from the engine. If you insist on fitting it then you will have to modify it to fit the pick up pipe, then increase the diameter of the holes in the bellhousing that the mounting bolts pass through. If you don't then I should imagine that it will crack the sump when tightening and putting unnecesary stress onto the sump.
The AAZ has problems, big problems, when buying an engine it is essential that you check theat there is no movement between the crank pulley and the crank. The design of the pulley assembly was such that after a period of time the bolt would work loose, the pulley would move on the crank and damage the pulley and the crank. If the crank is damaged then it is scrap, and if the crank is scrap then generally the rest of the engine is too as repairing or replacing the crank is not a cheap, or easy job. VW realised there was a problem and modified the pulley bolt to stop this hapenning but there are some unmodified ones out there so beware.
There are 4 different injection pumps fitted to the AAZ, some have EGR, some have NoX reducing measures also.
Doing the conversion with the info above will result in haveing 2 non genuine parts, the oil feed (Which some people just bend a 1.6D one into place ) and the oil return line from the turbo (JX one is too short) If you do it any other way you will have to make an exhaust, and if it breaks you won't be able to just buy one over the counter. Using as many parts from VW means when something breaks you can buy said part and not have to mess around bodging. If you are going from 1.6TD because you don't have enough power, then fix the JX first, chances are you don't like it because it's not been maintained properly, a properly maintained JX is a good engine with more than enough power for most people. Remember tappets are manual and not hydraulic and rarely get set, once checked they generally have very little gap, hence not seating properly, low compression – low power, valves get hot as they are not closing enough to transfer the heat away from them to the head so worst case is burnt valves, not good.
A AAZ is only 5bhp up on a JX, but it does have slightly more torque.
Pues si me avisas de eso paso, ya me paso una vez y lo que ahorraba comprando en china, me lo gaste ne impuesto de aduanas, a no ser que me cobren 50 euros de la culata y 20 de transporte
De todas maneras en amazon y en una tienda alemana, las he encontrado por 200 y pico de euros amc, tambien.
Creo que he encontrado al fabricante chino, o eso creo, por que se supone que es una empresa fabricante de culatas pero las culatas son AMC y lo pone en la culata:
De ahi se come material, se deja a la medida adecuada y listo, vamos listo por decir algo, por que vaya coñazo. Aun me acuerdo de haber visto como se hacian esos motores de simca y similares, que se hacian con unas galgas y unos tornillicos
Creo que solo migrare todo, pues no tenia ningun problema el motor antes de irsele la culata, no hay perras y hay que ir al duro.
Faltaria de saber par de apriete de los inyectores y los calentadores para se elegantes del todo…
El autodata que tal? Vienen muchos datos sietes? o en el haynes manual ese creo que venia todo. Si eso me lo bajo…
Mas dudas que me salen (Luego lo unificare todo, para hacer el brico):
-Desnuda es desnuda?, todo para cambiar de una a otra, hasta la ultima tuerca no?
-Las valvulas y los taques, se migran asi, como asi?, sin tener en cuenta deformaciones y desgastes? se ha de marcar en que cilindro estaban y que posicion, tienen que hacer algo a las valvulas los de los rectificaos?
-Que pares de apriete llevan los tornillos que sujetan el arbol de levas? Se ponen nuevos?, valen los viejos?
Pues me dejas mas tranquilo, desmonto, saco culata la llevo a comprobar y en su caso planificar, que esta rota, pues compro una pelada, donde las venden? Aunque ya os digo que con los precios de la rectificadora de huesca, igual hasta me sale mejor esa de 350, que seguro que esta bien… Me cobraron 75 € por rectificar 2 tambores…
Me sigue convenciendo mas llevar el motor original, por que es como es mas fiable y menos problemas te puede dar. Ademas soy el unico que le gusta el ruido que hace a barcaza el 1.6 TD?
Hoy cuando le he dicho 800 euros la culata a la parienta, ha dicho joooodooo, asi se pensara lo de no mirar el cuadro de agujicas y lucecicas… ya se me ha cargado 2 culatas la del saxo hace ya y ahora esta…
No es purismo, pero como oigo de gente que tienen mogollon de problemas.., de bombas de inyeccion, caja… y siempre se dice que lo mas fiable es la mecanica original…
Se supone que es:
Del 1.9 TDI el bloque-culata na mas y el resto del mio? Va asi como asi a la caja de cambios? es decir coinciden tornillos y como va agarrao a la cuna motor, asi como asi, o hay que adaptar algo? Hay que recalibrar la bomba? El de 90 cv es no?, con lo accesorios del JX, cuanto da 80 y mas par?
Mira que me pillo una grua de motores de 100 euros y asi hago 2 cambios de motor
Si ademas de tochista, soy monologista, me hago cargo…
Gracias por aclararme todas las dudas.
Lo de comprar por amazon, lo hago por que donde vivo Huesca, las ferreterias son muy caras, te pueden llegar a cobrar 10 euros por la punta esa, mas luego pedirla, hacerte esperar, dar vueltas… Todo loque puedo lo compro por internet y me ahorro tiempo y dinero. Gracias tio por el ofrecimiento, pero cuando me lie comprare una caja de herramientas ahi y me la pillare tambien.
La culata estoy pensando una de intercambio, o una que sepa que esta bien antes de montar, la opcion mas economica que tengo, es que me la mire el rectificador lo primero no?
Si, si la junta y lo tornillos doy por hecho que hay cambiarlos, lo que decia, es que si ha juntas de 50 €, pues que no me importaria, pero veo que lo mejor es Victor.
Seguire tu consejo y cambiare los tapones de dilatacion.
Por ahora a ver que me ponga a desmontar, a ver que sorpresa ahi.
Me voy respondiendo a mi mismo, constumbre que tengo para ir acumulando la informacion y si quereis me corregis, veo que los tornillos de la culata llevan esta metrica no? de 12 puntas?
