Dam*, I don't know where you been buying your plugs but Straight from Kohler is less than 5 bux.

Have you tried auto parts stores, Even NAPA is less than $5.....

For oil filters, you can make a much better deal. These have the same specs as the Kohler/Briggs filters.
Length" Wix Purolator Hastings Kohler B&S Baldwin MotorCraft AC JD TEC Walmart
2.3" 57035 NA LF503 2805001 492932 B7165 NA NA? ? 36563 NA

NAPA Gold & CarQuest Premium are a WIX.
Delete the 5 prefix from the Wix# for NAPA
CarQuest uses the same last 3 numbers with their prefix. (85)

Ok thanks.

Rob what other items do i need to service my mower
36" snapper

Looks like you have everything covered, Just a reminder; Use nothing but 10W30 oil in this engine and don't forget to put some oil on the pre-cleaner soaking the excess up in paper towels before installing on the filter. Check all your belts for wear and proper adjustment. And sharpen/replace blades and check blade spindles for worn bearings.

Not Rob, but those are the part#'s

Spark plug is a Champion #

I do recommend a genuine Kohler FUEL filter.
Oil filter, you can save a BUNCH on the alternatives I listed.

Dang....You haven't serviced this poor thing yet ????

I can see your next thread now;

Hey guys, my CV12.5T now has a bay window in the side. :cry:

Since I now have to buy a new engine can I put a CV15T on there ? Will it bolt right on and where can I find the best price ?

does it matter what length filter

also as mechanic do you have exactly how to service the machine?

09-04-2007, 11:30 PM
I suppose you are speaking of the fuel filter, If so any length is fine. As far as blow by blow service, Just install the new parts everyone posted and do what I said in post 13....

Oh, Don't forget to lube all grease fittings and spray all other moving parts and cables with "Fluid Film" ....

I was talking about the oil filter

I was talking about the oil filter

Well, You know bigger is better in most cases !

I use the long one when room permits....

I think bigger is better in MOST cases.
There are however, "some" bigger filters that have a "larger" micron rating. These are typically "truck sized" filters with a capacity of 1 qt. or so.
About the largest filter I would use, assuming you have room, is- the MotorCraft FL-400 Wix 51516 size. It's 4.8" long and still has a good micron rating.
I consider the larger filters to be a "poor mans" oil cooler. You have a few more sq, in. of surface area to transfer heat, plus a few more oz. of oil to act as a "heat sink". This would be useful in situations where the load on the engine includes short periods of maximum output where it'll be generating max heat. The extra capacity allows more heat absorption during this time and then can be dissipated when the engine is under less load.
OTOH, this probably wouldn't be desirable in cold weather. The smallest filter may actually make sense, in allowing the oil to warm up as rapidly as possible.

Spark plugs- stop by your "generic" chain type auto parts stores and pick up a 4 pack. You should be able to get a MUCH better price!
Supposedly that plug will fit a-
1993-2000 Dodge RAM 3.9 V6, 5.2/5.9 V8 among others.
R resistor
C compact
12 heat range
Y extended tip
C Copper
I prefer to stick with the plug brand that came with the engine. Plugs are part of the "emissions package" and have to be warrantied to last as long as that warranty is in effect. To me, that means they aren't going to just stick "any thing" on it. Stick with the factory plug. (and I'm an NGK guy)
Just my $.03!

how much oil do i need for this??? last time I serviced the mower the oil was still good

04-09-2009, 07:33 PM
Two quarts will cover it, It won't quite hold both.....And don't screw the dipstick down on the threads to check oil level, Screw it backwards slowly until you feel it drop down a little then remove to check the level.
