Tazza, I've been doing a lot of reading and I came across a post, long ago, where you discussed checking hydraulic pressure etc. The manual says to use a MEL1355 Pressure Test Kit....well, the sticker shock has me thinking about making my own test kit. I came across a site that listed all the parts for the kit. I can pick up gauges for about $20 apiece, and I assume the fittings and hose cannot be that much. Anyways, this is the item list for the kit: http://www.handsontools.com/Kent-Moore-MEL1355-Pressure-Test-Kit-for-Excavators-_p_74673.html Kent-Moore MEL1355 Pressure Test Kit for Excavators This kit consists of: MEL1355-1: Gauge 0-400 PSI MEL1355-2: Gauge 0-1000 PSI 45763 (Fluid Filled) MEL1355-3: Gauge 0-5000 PSI 303261 (Fluid Filled) MEL1355-4: Hose Assembly 60" MEL1355-5: Male Quick Coupler 1/8" NPTM 214026 MEL1355-6: Adapter 1/8" BSPTM x 1/8" NPTM 304725 MEL1355-7: Teflon Tape MEL1355-8: Socket 1/4" Sq.
