Tool size for 240D's manual transmission FILLER PLUG.

[ericnguyen]

Dear friends:

I've heard that a 14 mm Allen Hex is needed to remove DRAIN PLUG for 240D's manual transmission even though a different tool (and size?) is required to remove the same manual transmission's FILLER PLUG. Is that true?

If so, what's the required tool for the FILLER PLUG?

Thanks,

Eric

On my 240D manual both are 14MM socket head (Allen type.)

Have you crawled underneath and looked? The fill plug is too close to the tunnel to get socket and ratchet in place. You can cut a piece off of a 14MM Allen and use a box end wrench on it. This will give you access.

Always remove the filler plug before the drain plug. The last thing you want to do is to remove the drain plug, drain the oil, then find that you have no way to refill it.

Good luck,

Dear LarryBible:

Thanks a lot for your precious information regarding lack of space
to access the manual transmission's fill plug.

BTW, do you know a MB tool (part # ?) specifically designed to open this fill plug?

Best regards,

Eric

Part # 117 589 02 07 00, actually a HAZET tool with the Star.

Might just work for your application. Has a 14mm allen on one end with a 1" side and a 1/2" side, whicle the opposite end has a 13mm box. Don't recall how much it was though.

Thanks Mike Tangas,

That little tool part costs US $47 !!!

Gosh, the German tool manufacturers have always fleeced their
customers with exorbitant and ridiculous prices for their tools.

Long live Taiwan or China-made tools (from trustworthy US distributors of course). I just wish they could make more specialized tools.

$47, that's about what I paid I think. One of those things you gotta have sometimes, me I needed mine for the rear diff fill plug on the 560. Some of the other tools cost plenty more. Best part about buying your own tools is you'll always have them (unless you lend them out and never get them back), not a regular consumer item.

I made one by grinding a large cut off hardened bolt useing a 14 mm allen wrench as a guide I ground it with an angle grinder till I had a snug fit ,it also works for the plugs in the differenials of my 126's.I think I used a 3/4 inch hardened bolt cut it to about an inch in length and the used a 3/4 inch box end wrench to loosen the plugs, they were quiet tight but the big wrench made it easy. I traded one to a local lube place for a diff. flush and refill. If you have and angle grinder use a new wheel(as they gring flater) it only takes ten or so minutes to make one............
