Steering Rack Bushings

So John Pirtle has a good procedure on the web at http://members.rennlist.com/pirtle/svc_sr.html#buchse , I have had the bushings for a long while but hadn't got around to putting them in. For one its a PITA job but seeing as I was going to have to do the pan gasket again I decided it was as good a time as any and with the rack removed it would leave more room under the car too.

Car loves to duck and dive on the rutted freeway, I doubt these bushings will solve it but a) you never know and b) it can't do any harm !!

So 1st shot below shows the last of the old bushings in the rack, the metal that is bent over is pretty flimsy but when they went in they did so with a press and the outer rim is crimped pretty hard.  Once the crimp had been reversed (not pretty) I bashed the bushing out with a socket.

Now to press the new ones in ......

Pan Gasket II

Because I didn't tighten the cork gasket down tight enough last time it never did reseal once I re-tightened, unimpressed with the flimsy cork I bought a more updated one impregnated with rubber. http://www.ultramaticdynamics.com. Others have reported long term success with this ... we shall see.

Have been using Mobil 1 and the pan is a lot cleaner (inside) than when I last removed it, detergent must be working well.

I lowered the engine onto jack stands where the motor mounts attach to the block if I had to leave the engine without the x-member for any period of time.

Rod Bearings

Oil pressure has not been right since I have had the car, could be a bad dash gauge but with the pan gasket off its a cheap and worthwhile item to do WYAIT. Last time I was in a rush to put the car back together ... As you may have read earlier this is a replacement auto engine so I gave the thrust bearing a visual and all looks OK, phew.

I have since removed the strainer for the oil pump to give better access to the bearings, difficult to get a good shot as the bottom part of the engine is pretty much in your face when you are under the car.

Off to the store tomorrow to get some plasti-gauge and then to order the bearings. I also removed the spark plugs so rotating the engine would be easier.

So here is the lower half of rod No2, this is not good.

Here is the assembly lube I used to coat the bearings with on re-assembly

  

All the bearings, 1 and 2 both showed signs of wear on the lower shell.
