The dreaded reman

<< < (2/2)

Cliff Ruggles:
Done long ago helps.  In the past 15 years or so most are PATHETIC and not worth putting a lot of time into.

They do drill out idle bleed holes, DCR's, and HUGE idle tubes, plus many will have driven in MAB's much smaller than stock to establish a "generic" calibration as they don't stock many parts and basically they are all a "one size fits all" deal.

Not trying to paint a big black cloud over it, just make sure than the castings are sound, plating on the metal parts so it's not a big ball of rust in 6 months, and great attention to detail with good parts used to rebuild it.

I can supply the parts, and help out with sizing of the air bleeds, tuning, setting it up for the application, etc.......Cliff

Thanks Cliff. The castings seem ok.
I punched out the bypass plugs.
MABs look stock, DCR's look stock also.
Have not removed the idle tubes yet.
Will do some measuring and see what it has.

matt68:
   Did some measuring and most of it seems reasonable other than the main air bleeds and pump discharge ports.
   The main air bleeds next to the nozzles are .125.
   The pump discharge ports are .063.
Guessing I am going to have to put some restriction in.

The other specifics are:
   Idle tubes .031
   Down channels .045
   Upper idle air bleeds .062
   Lower idle air bleeds .066

77cruiser:
Did you go all the way in for the discharge nozzles? The outer hole is big all the way in should be smaller. Like .025 ish.

matt68:
Not in far enough. I was measuring the big outer hole. Thanks.
