Smog Pump Rebuild
|
Tech information furnished by "PabloCruise" I wanted to pass on some information on rebuilding a smog pump after I successfully rebuilt two of my own pumps. The vehicle in question is a 1978 FJ40 - Federal Spec. It was originally missing its air pump. I got two from various sources. When disassembled, one had vanes and wipers, while the other one turned out to be a shell. I rebuilt them both and put the functional one on the vehicle and put the decoy on the shelf. My buddy and I carefully pulled the pulley by threading the two holes in the pulley to accept a puller. We then soaked the case in carb cleaner to get rid of the funk inside. I purchased all the bearings I needed for a total cost of $22! Part numbers are as follows: Front bearing 6203-2RS (Qty 1) Rear bearing B188 (Qty 1) Vane bearings BA65 (Qty 4) The place I bought these from said the part numbers should be industry standard. The front bearing is an upgrade, as part number listed is a sealed unit, while the one that stacked up in my pump was a shielded unit. Pump works well, hasn't seized yet! It has since made the trip to Moab and survived some shallow water crossings. I built these pumps in early March, and the one on the vehicle still works well. I just took my emissions test and passed with ease. I hope this information helps some Cruiser heads get their pumps working so they can pass the emissions inspection. Posted February 22, 2005 |
