Reassembly White RZ

[85RZwade]

great progress! If those cylinders show up any color BUT pink, I'm gonna be disappointed.

Thanks!
I got them but haven't unboxed them yet. I am in the middle of my 1st gout flare-up in 25 years despite daily meds so I can't use my left hand. I had some Wageu beef and that proved to be a mistake. Urgent care is in my future later today...

Today in the shop was FPP expansion chamber refurb day. I bead blasted the spigots and then wire wheeled them.  In the shop oven for 30 minutes at 250, then shot some Rustolem 2000 degree black snd back in the oven for an hour at 250.



While the spigots baked I cleaned up the pipes and scuffed them up with some 360 grade wet or dry tri mi, wiped them.down with acetone and tacked them off good. The packing was shot after 3 years of hard running and will be replaced.

Today was clutch cover prep day. All new seals, new Economy Cycle billet impeller and new bearing. Lexan window temp installed for photo.

I love new tools! Per M in SC I need one of these and from what I can see there is no other way to properly torque the inaccesibble RZ350 cylinder nuts other than a crows foot as Mark indicated. $21.99 from good old Amazon Prime free shipping MotionPro 08-0134.

Today was clutch cover install day complete with Allen head bolts from Yambits and the window from Seans RD an ebay vendor who manufacturers them in the UK. No leaks after 2 hours. 1 quart of Lucas 80/90 for leak check purposes and to slosh around on the clutch and gears. Kicker appears to operate normally as well.

Today was Wossner piston prep and install day.

I saw those but looked at their users manual for it and didnt quite understand the conversion formula to use it?

M in SC correct me if I explain this wrong.


T is the torque value in this case 18 ft lbs for RZ350 cylinder base nuts.
L is the dimension from the center of drive on the torque wrench where a socket goes or in this case the center of the adapter to the center
of the grip on your torque wrench.
you need to adjust the torque wrench setting to compensate for the extended moment arm which I think has to do with the increased leverage provided by the adapter.
A is the length of that extension.
So 18 x 14.5 =261 on the top line.
14.5+3 = 17.5 on the bottom line.
Divide 261 by 17.5 = corrected torque setting  of 14.91 which I will round up to 15.
I used to be a Flight Engineer but I haven't done any math remotely like this in a long long time so please correct me if I am wrong.

In the last twelve months I have had need for one of these tools and almost purchased one. I had no idea a calculation needed to be made to use the tool correctly.

What was your reference for the formula for calculation? Does this come with the tool as instructions, have you sourced these instructions elsewhere, or has a mathematical background told you a calculation needs to be made?

Whatever the way, thanks to you and the forum for this gem of information. Great stuff!  : thumbs:

the instructions come with the tool. you are increasing the length so you need to use a 'lower' indicated value.
 below file is the instructions from motion pro.

And there it is. Thanks Mark!

Does the calculation work out as a general percentage, or is a new calculation needed for different torque settings?

Yes, I read those but still dont quite understand the bottom line setting I need...math has never been my strong point.

you can use the adapter at 90 degrees from the arm and supposedly will need no conversion.
