I've always assumed that the strainer is zinc plated, base on appearance. I know zinc should be avoided when in contact with diesel. There are lots of tutorials for home plating and nickel plating is pretty common with good results. As far as I know, and correct me if wrong, but there are not...

Great news Kurt!

The mystery deepens... I measured flywheel runout again from a more consistent point on the engine block. Found a low spot measuring .010". Pulled the flywheel and found out its about 1/8th inch too big to fit in the lathe. The crank bolts were not fully tight and the mating face of the...

- Any black goo seeping from the exhaust manifold? - how is your output power configured? What is your load configuration? - are you getting black smoke from the exhaust A) At no load? B) At part load? C) when engine bogs? -is the exhaust smoke an even stream and big pulses? - how old is...

It's getting harder to find replacement gauges and a prebuilt system (screen) that could take the place of those gauges would be great, especially if the costs could be kept to a hobbist/consumer price point for the screen. Also if the back end bits were modular, that would help servicing and...

Thanks Ray! I thought those were just dowels, like you said.

I've looked through the TMs for the genset and the engines, but cant find an answer for this one. How does the engine generate vacuum in the crankcase? Every diesel I've worked on has a very obvious crankcase vent line that terminates between the cylinder intakes (or turbo inlet) and the air...

2. Unless you understand the inner workings of the gauge and could build one from scratch, i doubt it can be fixed. I haven't given't up on a couple of mine, but that is a challenge for a later date. Members here might have one tucked away. Ebay is another source. All things being equal and...

2. Gauge is likely bad. You can also verify this by placing an ammeter inline with the PRC gauge. Full gauge reading (133%) equals 1 amp AC through the gauge contacts. 100% load would equal 0.75 amp AC, etc, etc 3. Try the Deoxit first. The voltage regulator senses voltage on L3-N and...

1. There is a test procedure in the TM. It involves placing an ammeter inline with the frequency gauge and comparing results. This will tell you if the gauge is wandering or the transducer. 2. The 803a is a 10kW generator with a 0.8 power factor, meaning full rated amperage is 52 amps at 240...

With the rotor out, I measured axial runout on flywheel face and didn't see anything out of the ordinary. Reassembling the rotor onto the flywheel, I remeasured runout at the end of the shaft and was still getting at least .020". I called it a night, but tomorrow I plan to remove tbe rotor and...

I pulled the rotor out and set it up on the lathe between centers to measure runout. Axial runout on the adapter plate was .006", measure mid-radius. Since the adapter is sheet metal and not necessarily true, I removed it and the support bearing and remeasured axial runout on the rotor's...

Went ahead and disassembled the genhead in place by removing the rear sheetmetal and sliding the housing and stator out the back after supporting the engine. The rotor looked visibly off center when observing the gaps between rotor poles and the stator laminations. I placed a dial...

I like where this is going. Great project! I was looking at my 802 the other night and thinking about something similar.

Have you verified K16 is pulling in? They make a pretty good click when energized. Also, pull the relay and manually apply power to the coil, then verify 7 and 9 are connecting. Another thing to do is manually jumper 7 to 9. 9 should only be energized when K2 is pulled in. Then check the...

Have you checked for continuity between the pin receptacle on the relay base and the terminal 7 connection? Also check the same thing on terminal 9. Having two bad relays is not impossible, but the relay base is part of the circuit chain and easy to validate.

At this point, it seems like I need to separate the engine and genhead to verify proper assembly and/rotate their relative positions. For those that have done this, is it possible to separate the two in the enclosure just enough to unbolt the genhead from the flywheel and re-index them to each...

Looking at the wear pattern in the skid base and broken weld in the left battery area, this unit has been shaking hard for a long time.

Well, no luck here. The paint shaker shows 88-21070-1 isolators, which crossreference correctly with-24P part number (88-21070-3) My 803a uses 88-21070-2 isolators. The -24P calls out 88-21070-4, which I can't cross-reference, but the convention follows similar to the 802 isolators.

It reads 12.7v and 14.8v when charging? Yes, that is possible if the batteries are out of balance. (Different states of charge) It's also potentially damaging to the batteries because the alternator's regulator only understands that it needs to output 28.8V, and if one batt has a low state of...
