Does anyone know if a 73 504 sump can be removed with the engine in the car or does the motor need to be out. I have a leaking gasket i want to replace.
single , Ive just renewed it with a new one1973, eh ? That's an old one. Have you got a single circuit brake master cylinder or tandem ? If it's single, I hope you renew it regularly...when they fail, they fail completely. But new ones (or re-sleeved in stainless, with new seals) are fairly cheap, really.
as beano said sump removal can be done with engine in car,in addition to beano advice would be to remove fan shroud securing screws as fan will hit on top of shroud when engine jacked up,may also need to remove both sway bar 13mm bolts securing D rubbers,let swaybar drop down and slide sump through between front cross member and sway bar.also keep an eye on radiator hoses when jacking up engine so as not to damage hoses or radiator outlet pipes….JimDoes anyone know if a 73 504 sump can be removed with the engine in the car or does the motor need to be out.

This is the bit you need to fix your hand brake from dragging. Part Number 4408.04. They crack with age.Only other problem to keep an an eye out for is the phenomenon of the rear brake calipers not releasing properly, which causes the pads on whichever side is first affected to overheat (you'll smell it) and wear out. Are you aware of this ? Short-term fix (to get home) is to whack on the arm (the one the brake cable is attached to) to manually push it back towards the wheel.. Use a piece of wood or a rock if necessary. Long term fix is to fit "helper" coil-type springs. Therre's a thread about it somewhere.
Replaced the proportioning valve in my 505 today. The brakes are no longer sticking on and it goes a lot better because of that. Also the vibration at 100 km has gone, presumably caused by the rear brakes being stuck on.Thanks for the prompt - need to do my sump gasket as well....
And rebuild rear calipers....
And rebuild front calipers
And probably worth replacing seals in Master Cylinder (be 5 years since I last did them)
But my brake proportioning valve is new!
Joys of owning a 50 year old car.....
aaawww,bit slow in backspacing brain,but while sump is off I would check around rear main cap side seal rubbers to see if they have shrunk back a bit which would give a small gap between seal and gasket.also check rear main cap that oil drain hole is clear.at other end of block at timing case end I would check area where front cover plate that timing case bolts to and engine block meet as sometimes can be a small gap there where gasket is.also check,if steel sump,bolt holes Aren’t tuliped from over tightening causing uneven pressure sealing of gasket.lastly the obvious crankcase ventilation via wire gauze filter in oil filler tube is not blocked.another couple of thoughts….jimDoes anyone know if a 73 504 sump can be removed with the engine in the car or does the motor need to be out.
