Ramblings....

It's only been a couple of days and I've learned quite a bit about engines. As previously mentioned, the accessory 'housing' (not case) isn't machined for a fuel pump. After posting a message in the Lycoming Yahoo group, I received a couple of responses. In the end I spoke with Mahlon from Teledyne Mattituck. (1-800-624-6680 ext.305) He sent me some pages out of the illustrated parts manual along with part #'s. He was extremely helpful.

Turns out I'm going to have to spend a few $$$. He has an accessory housing for $250 with trade. I'll also need a drive pin ($136) and possibly an idler gear if the one in my case isn't the right one ($231). On top of that, I still need the fuel pump itself ($195).

So.. for all of you out there shopping for an engine, make sure you get one that has ALL of the pads that you need machined before purchasing.

The other suggestion he made which I think I'll follow through on, is to pull at least 2 of the cylinders. This accomplishes a couple of things for me. First, it gives me interior access to lubricate everything. Second, it allows me to see the condition of the inside. Lastly, I can get a better look at the cylinders themselves. Since I'm going to exchange the accessory housing, I can pull it off too and lubricate all the gears and gadgets in there. This will also tell me whether I need a new idler gear.

By the time this plane is done, I'll know every little nook-n-cranny, including the engine!

Engine arrives

I picked up my engine today from the freight docks. Managed to get it unloaded with the help of my tech counselors who happened to be visiting. :-) Engine came out of a Cessna 172. Has ~2500hrs TT, 1145 SMOH with accessories. The alternator/starter are 28v, so I'll probably sell those and get new lightweight 14v versions. Has duel impluse slick magnetos and vacuum pump. Discovered that the pad for the fuel pump is not machined, so I will need to get another accessory case that has one on it. Not sure if I can have mine machined or not. The engine has been sitting for a number of years, so I need to get it preserved.
