I just got this XJ40 and have been trying to diagnose a brak problem. I noticed the two outlets on top of the The green plastic HSMO reservoir are different diameters. The two connecting rubbere hoses are also different diametrs. It seems the larger hose was connected to the small outlet and vice-versa as shown in the Pic below. I removed the larger hose from the smaller outlet pipe but I cannot remove the other pipe.
Logically i would think Big to big and small to small but why would someone swapp these around?
Questions.
Am I correct and the lage pipe should go on the lage hose and etc…?
My 89 factory setup on green mineral oil tank… has Larger reinforced hose towards firewall it had worm drive hose clamp fitting towards front-radiator small hose and mine has spring tension clamp.
I just hope the other end of the hoses are where they are supopoosed to be. It is annoying when you do not know whether a cowboy worked on this car or someone who knows what they are doing.
I am having trouble with my Cruise control also so i may need to buy the Factory Repoair Manual as the Haynes is not detailed enough for my issues.
At the green mineral oil brake reservoir the larger hose, with reinforce fabric scrim, the one closest to firewall goes to the LOAD-CHARGE solenoid connected-screwed into the top of VALVE BODY.
The other green reservoir hose, the smaller of the two, the one closer to the radiator goes to the hydraulic brake booster. I’d be surprised if anyone even cowboys switched hoses…
Hope it helps
Yes it clears things up for me very well. Thanks.
I have managed to prove that my Accumulator has ruptured by poking a piece of wire into it and the rubber if flat against the top of the bulb. No pressure at all.
I have ordered one from Jagdaim for about $300. This should fix my brakes.
Whole lot more to do on it though. See my Restoration post for more details. My 1988 XJ6 Restoration
Thanks. i will try to use this site. After a quic look I cannot see any place to search using the VIN. i will have a closer look at the site later as I am busy now.
You first select the VIN range of your car then click through to the part needed. The final result will show you if there is a variant or superseded part number and that choice will be determined by the VIN of your vehicle.
Sometimes there isn’t a multiple part designation listed, but often there is.
It depends on the type of part selected, however attempting to order correct parts WITHOUT referring to these part catalogues can be a very costly exercise indeed.
Suppliers are generally fairly hopeless without exact part numbers.
Getting the part number or cross-referencing to aftermarket replacements can save you a pile of money (if that is a concern; many don’t care how much it costs) -for instance, brake accumulators that can fit the 40 can vary in price from under $100 to astronomical $$$.
Thanks for clearing that up. You are right about saving money by making sure the part will fit when you can’t see before you buy.
I will give it a try.
