572's motor has lost 15psi of hot oil pressure since i have owned it.  id get a 10 or 12 psi switch instead of 20.  my 20 blinks at hot idle.  its annoying.

Trans temp sensor working, interested to see how warm she gets at Rausch in some go fast and big uphill rock trails. Going to be hitting it hard after to make the race 4/12!

Winching in the comp course with no winch brake or brakes = not fun

and a high stall converter that stalls the engine when rolling backwards doesnt help either.

[GBR928]

Yeah fail on that too. Frustrated

id be more agervated that the steering system is 100% the same as 572 and 571 and it continues to fail pumps. 



Should give a pump to gifford to take apart and figure out whats going on.

I read up last night have some things to try with existing system.

Steering system update:

Found metal flakes in fluid (needs flushing) I assume this is from the pump I wore out with my old non load reaction orbital. Never flushed for new pump/load reaction orbital put on.

Going to add a filter and a non remanufactured pump with something better than ATF as a fluid.

Some of you run the Tractor Supply stuff? Anyone have specs or details on what type? Heading there tonight before the FLX meeting.

Adding copycat larger MC for added braking like 572, dropped my brake booster and ruined sealing surface. $130 on summit back up if J&J doesn't have any this weekend. Possible test and tune this Sunday at Rausch! My brother Joe is in to go!

Also smike came up with a good idea last night for lower link anti twist bars from the lower links to the rear axle housing, we have materials an rod ends to get it done as well!

schematic shows how the return fluid goes into the reservoir after the cooler.
This allows any air to rise to the top.    Air free fluid is pulled from the bottom of the reservoir into the pump.
reservoir should be the highest point of the system.

P185 pump is what we want

P185 was available in 97-99 chevy Medium Duty trucks with a 6.5 diesel.

most "P" series saganaw pumps will put out between 3 and 5 gpm depending on flow mod and pump shaft speed

keep in mind there are different stile P pumps there is the p132 and the p185
the 132 is the every day run of the mill p then the 185 has the larger ring and rotor (it pumps more oil) which is like the "1400 pump" from PSC

there is only one true way to tell the difference between a P132 and a P185 and that is to compare the ring and rotor (the P185 ring is .200" taller)

***  most re builders seem to use the lower flow pumps in applications that were factory high flow ***


top pic is 185    bottom is 132




Hydroboost brakes "P" style saginaw pump with attached reservoir (1980 Chevy K30 4x4 1-ton with 350c.i. and Hydroboost brakes)

I figured you guys would have been running "TC" style pumps not the "P" pumps

Is there a tc pump that flows as good as the 185 pump?
