4. JACKS
A. Travel Trailers
On the top of the jack is a metal cover attached with a wire spring
clip. Remove cover and inspect gears for grease. Re-grease if there is
none there or it has dried out. Some brands of jacks have a hole placed
just below these gears to insert oil for lubrication of the ram so it will move
smoothly, ten to twenty drops annually will do the job.
B. Landing Gear Jacks (Fifth Wheels)
a. Extend landing legs as far as possible, clean drop tube and inner
ram tube. Coat exposed surface or tubes with silicone spray
lubricant.
b. Coat inside of handle alignment tube with silicone spray lubricant.
c. Oil shaft bushing in gear box and leg gear heads with SAE 30 oil.
d. Lubricate gears in gear box and landing gear heads with extreme
pressure grease.
On 2000 lb. rated jacks there is a flat plate on top attached with spring
clips. (Not in production since 2003) On 3000 lb. & 4000 lb. jacks there

amp fuse. If replacement is necessary, replace only with a Buss Type
AGC-30 fuse or equivalent, available in automotive supply stores.
5. TIRES
Tires installed on your RV are matched to the weight of your coach
according to the rating of the tires. The most important item in tires is
to inspect and test air pressure no less than once per week, perhaps
daily during travel. Correct PSI air pressure is listed on each tire as per
rating. When air pressure is not maintained as specified tires will run hot,
especially in summer months, and blow outs can occur. Pressure must
be always be checked when tires are cold, preferably in the morning. NO
NOT adjust or lower tire pressure when warm as it will be too low when
