It appears that they offer a full kit. I am also curious what exactly was ordered. I am assuming OP also ordered the loaner tool?

Looks like he ordered the kit.

The kit from BE also comes with a new temp sensor and high performance oil, I didn't install the temp sensor, but I did siphon out the old oil from the reservoir and replace with the new oil. If I can get access to autoenginuity, I would like to completely replace the old oil with the new oil but that will have to wait for now. Overall, it was a good experience and I could probably do it in half the time if I had to do it again.

Nice DIY and video. This may come in handy, but so far my SMG has operated flawlessly.

I'm a little suspect of the fluid. Do you know what it is? CHF11s has some pretty strict cautions about not mixing it with ATF (CHF is used in place of ATF in the power steering system for cold climate cars).

I might be off; the thicker oil will net pressure more quickly, but doesn't this put more strain on the motor with less frequency?

definitely should have waited til this was posted ugh...great DIY hopefully i find what is causing mine to have an issue of not starting or prime on its own..great news is that it primed while getting bleed since i removed the whole system.

take in mind this car is designed to operate from very low temp to high temp. I would guess -30C to +100C as normal operating temperature. The viscosity of any oil at -30C will be much different than at +100C that been said putting a new oil which viscosity is a little bit higher is the same as vehicle would be running a lower temperature but should still be within operating range. I do see advantage of having pump cycle less often.
is the temp sensor just replacement for existing one?

Thanks everyone!

To answer a few questions. Yes, I ordered the repair kit from BE. It came with everything needed except for the tool to push the pins out. I ordered that separately and don't see how you could really do the job cleanly without it. It's a simple tool, but the last thing you'd want to do is to break the SMG wiring harness connector as I doubt you could get a replacement part.

As far as performance, the car has been working great over the last two days and 100+ miles I've put on it. The real test will be my commute to/from work this week as it will be in the mid to high 90s. With all of the concrete and other cars around, I'm sure the ambient temp reported by my dash will be 100+. Typically, I've had problems any time the car showed 90+ degrees in the past.

As far as the power output of the motor, I'm not 100% sure. It is slightly smaller than the OEM motor but felt heavier in my hands. The smaller size made it much easier to put everything back together, which was a plus. I'll send a link to this thread to BE and see if they can clarify specific output of the motor compared with the OE unit.

Hi everyone,

and a special thanks to Stephen. Your DIY video is great!!

And you're right - also very important for the success is the change of the hydraulic oil and that the rest of your hydraulic unit is in good condition (this is usually the case).

In the following I try to answer all your questions:

Very important during our development with our oil supplier was that the hydraulic oil is mixable with the Pension CHF 11s. You should try to get out as much old oil as possible but it is not necessary to flushing the hydraulic system.

Because of the thicker oil your pump can be more efficient and you have less internal leakage due to low viscosity. You should not use the oil under -20 celsius.

The new motor has more output power than the old one but it is still a burst motor.

I hope a questions were answered.

Johannes
