I am trying to find the size of the sensor plug in a Ragusa FD Cover. I put it on then decided to add a temperature sensor now that it is full of nice new oil. Is it metric or SAE threads ??
No comments about planning ahead, please.

Thanks Jim. I have a bunch of adapters. I can narrow the selection a lot and hopefully lose less oil until I find the right one.

Why not just call Chase Ragusa and ask him?

The sensor is in !! I measured the exposed threads on the plug and called Ragusa. The hole size is 1/4" NPT and with a 1/8" NPT sensor in an adapter all fit well. Only lost a small amount of oil changing the plug and sensor.
Thanks Jim, Ken, & Johnny

Al,
Almost all GMC MH accessory are non metric.
I discourage people from using metric as you do not expect to see it .
Watch out on alternators and Torque convertors.

It's sometimes useful to remember that GM issued a decree, IIRC in 1973,
that all NEW designs from 1974 on would be metric. SO, there was a long
period, including most of GMCMH production run, when "old" designs were
continuing to be produced, with "new" modifications -- in METRIC. Talk
about a mish-mash! And the world still suffers from a lot of that fiasco
-- but what else could they have done?

before you toss that plain steel cover search on youtube for a series of videos by Gale Banks where he scientificly analyzes aftermarket diff covers. Almost all of them upset fluid dynamics and aerated the fuild, starved the pinion bearing, and wasted energy making it into heat. There is a reason that ugly stamped cover is shaped as it is.

The GMC rotates opposite of a rear drive. Cover is on opposite side.
The cover on our unit is designed to accommodate clearance of the front
steering .
These Ragusa covers have been running on our coaches since 1985 and have
never seen it cause pinion failure.
Having sold over 3,000 units, if there is a problem I would have heard
about it.

A closer look gives me the impression the Ragusa on my 26' has the same contour - except the fins on the outside - as the stamped one. I've not set them side by side, the 23' with the stamped cover is gone. I side with Jimmy the K though - after that many if there was a problem it would of come up by now.

Agree. If the inner contour and volume is same, it's probably behaving the same. Still a great study by Banks and brings awareness to aftermarket and their unknown R and D compared to OEM. Lots of performance claims that are simply not true.
