Default Maytag Model 72 - Shaft Seals

I know the Maytag part numbers are oil/shaft seals 14451 an14452.

Is there an aftermarket part number for replacements?

jumper, the part numbers you refer to are oil retainer numbers . there are no oil seals on the maytag twin cylinder crankshaft ,the bronze crankshaft bushings with the internal grooves control the oil leakage around the crankshaft. but the bushings cant be worn out or the
oil/gas 16/1 mixture will leak by them. the oil retainers are supposed to hold any excess leakage until it evaporates.i have known people that have tried to put o rings in the oil retainers but they normally dont work .so if there is too much leakage the only sure cure is new crankshaft bushings. i hope this answers your question

Clearance on these bushings to the crank are supposed to be about 2 to 3 thousandths. If you pick up on the crank, and you see visible movement, then the bushings are worn. Slight oil weepage is normal. If fuel/air is pumping out, then the bushings should be replaced and reamed into alignment.

I was given a model 72 on a Zip mower that hasn't ran for many years. After much cleaning, can not get fire at plugs and also have major fuel leak from bottom ofr engine at crankshaft. Where can I get new bushings for this engine, also gasket set? When checking coil and condenser, there is spark at plug wire but does noes seem very strong. Is that most likely bad condenser? Thanks.

The brass bushings are a Bunting No CB141714. They are 7/8" ID 1-1/16" od and 1-3/4" Long. Most bearing houses can order them for you. After installation they will need to be reamed to fit the crank.

the bushings and gaskets for your twin can be ordered from mark shulaw 1 419 516 2996 or bobs small engine 1 319 377 3339 or on e bay.as far as the spark, chances are the coil is bad, twins are notorious for that.
