Returning to check on the charge after our drive-free day in Valencia (a town well worth a visit!) everything was OK regarding the charge… but there was another issue manifesting itself on the floor of the garage I was parking in: A puddle of oil!
Hmm. Even if a TWIKE only has around 150 ml oil for its gearbox (a rather simple fixed-ratio affair which, nevertheless, can require servicing), losing said oil is never a good thing!
Looking under the TWIKE just before the battery compartment there is a huge amount of gunk – yuk!
As it’s quite difficult to remove the battery compartment and lift the TWIKE to check what’s going on (it might just be a loose oil sump screw … or worse, a faulty seal) I rather would like to check if the gearbox is already dry or if I can still continue to San Juan and have the time to decide what to do with some time on my hands and from the relative comfort of our apartment there.
Checking a TWIKEs oil level is very easy … if you have a stock, non-modified, ex. 2 NiCd battery setup TWIKE. There is a small cover between the seats that reveals a screw when removed allows topping up.
My TWIKE was a 3-block (long-range) NiCd version, which had an additional block just behind the co-pilot’s seat. I loved these 30 kilograms on the right, as it vastly improved handling.
Which is why I decided to emulate this block by placing my 2*8kg quick charging infrastructure at the exact same position, re-using the frame which already was there for the NiCd block.
Only one of the chargers needs to be removed – much easier than removing the 30 kg block that was there before!
The cable leading through this hole is a temperature probe for the motor.
Let’s undo the screw and see if there is a problem with the washer … and if there isn’t if there is still enough oil to continue our trip.
The easiest way to check is by using a white cable tie and push it down through the hole until it touches the metal at the bottom.
I have cable ties with me but mine are black. This isn’t a problem, though, as the following picture shows:
Whew! There is still some oil there and we’re still good to go for one more day!
San Juan, here we come!
