Hey guys. I'm hoping you can save me some time. I have the New RM Maintenance Manual and all of the Technical compendiums from the Association.

I am in process of having the Commercial Vehicle Safety Inspection done and am looking for some help on a couple of things:

Transmission Oil Leaking
Wheel Cylinder Leaking (send to Imperial for Repair?)
Steering Oil Leaking (send ram to Imperial?)

I am also in need of wheel studs and nuts, nearside and offside- and idea on a supplier?

Thanks

You are not saying where the oil leak is coming from on the transmission. If it is an oil seal there is a possibility that the flange nut is loose - leave it too long and the shaft's splines will be damaged beyond repair - assembly scrap. If it is a porous gearbox casing there will not be a lot you can do. If it is an RM rather than an RML the complete rear propshaft has to come off to do the diff pinion seal. All transmission seals and wear sleeves are available.

A leaking wheel cylinder is an immediate urgent issue. Vehicle off road until rectified. Send to Imperial.

Wheel studs simply are not available. I tried some years ago. Fortunately it ended up as someone else's problem.

Maybe take the bu to a specialist in RMs for safety check for a second opinion?

Imperial do rebuilt or new wheel cylinders but they are not cheap. Having changed one , will your garage know how to bleed the system properly or how to check the accumulator pressures?

I can re-charge the accumulators. Is the bleed procedure in the manual?

There are no RM specialist here in Vancouvet so I am slowly becoming one.

Any advice/direction would be very much appreciated.

Thanks

Aha, that explains it then. :) I don't know about what's in the manual, most of my knowledge was got before the manual was printed! To bleed the brakes, with bus over a pit run the engine, wedge the brake pedal down with a bit of wood or get someone to sit in the cab with the brake lightly applies, go round each wheel cylinder and open the bleed nipple until fluid free from bubbles appears. BEWARE, this is a very high pressure system, 1200 psi or more can come out! When that's done at each cylinder, release the footbrake then top up the brake oil.

Don't pump the brakes as you would with bleeding car brakes!

Thanks a lot.
